Skippern's diary

Recent diary entries

Testing of GPS, gathering tracks, new car, new job, etc

Posted by Skippern on 18 October 2013 in English (English)

There have been a lot of changes to my life since last post. I have changed job, my new job will give me quite some traveling around, mostly in Brazil, but might also be some travels abroad. Much of this travel will be with hired drivers (taxi, VIP service, etc), mainly between communication hubs and ports. Since I had my new GPS last July I have brought it with me, partly to test the data quality where I travel (I have OSM maps installed, latest update from garmin.openstreetmap.nl ), partly to gather tracks, along with recording POIs with Go Map!!

Further I played around with Java/Eclipse, and got some basic Java into my fingers, I hope I can get something useful out of this soon (might or might not be OSM related)

By getting myself a Macbook Pro computer I extended this to Xcode (the platform for iOS (iPad/iPhone) apps), and will try to make some useful/interesting apps for these platforms - might be a mapping tool, might be a navigation tool, might be a game

If anybody have some GIT/SVN repositories for any Java/ObjC/Xcode OSM related projects, let me know, so I can be connected with it, so much interesting to learn within these fields.

We have just changed our car, the new vehicle is a Chevrolet Cruze, which is the new family car, that will bring us around when visiting people, going on holidays etc. The car came with a multimedia/navigation system, which I can use to compare maps when traveling (against my GPS unit)

We have plans of getting another car, maybe a Chevrolet Montana, a pickup that will be used mostly for work related activities (and some outdoor activities as well)

Garmin Nüvi 50 with OpenStreetMap

Posted by Skippern on 9 July 2013 in English (English)

My wife have recently been on a holiday in Europe, and one of the things she brought back was a Garmin Nüvi 50 Car Navigation System (with preinstalled maps of western Europe with speed camera information). Western Europe map is close to useless for me, so I quickly dived into the fountain of wisdom called the OpenStreetMap wiki, as well with other GPS and Garmin sources

After trying a bit different sources, copying maps in different formats to different places on my GPS I found the following to work:

  • Go to Garmin Dashboard WebResource
  • Install the plugin they suggest
  • Go to garmin.openstreetmap.nl
  • Select the map regions of your interest, along with stylesheet, etc, and generate
  • Download the gmapsupp.img file, zipped
  • Unpack it to Garmin Device root.System\ folder
  • Replace your gmapsupp.img over the existing gmapprom.img

I liked the interface of garmin.openstreetmap.nl, the only thing that wasn't completely clear to me was source age (are they generated from minutely updates? daily updates? weekly updates?

I am now just looking for an opertunity to take my GPS for a spin to see how good the maps are. AND: When I see something wrong on the GPS, I can take up my iPhone or iPad and correct it on the fly with Go Map!!, that way next time I download a map, it's already corrected.

Next step will be to find out how I get POI displayed in a zane way on my Garmin Nüvi 50 device

Progress Note February 2013

Posted by Skippern on 16 February 2013 in English (English)

I am running out of motivation of doing any organized mapping. Partly because things I have wanted to do is coming to an end (I have reached the bottom of the stack of available data from the Brazilian hydrographic, and have traced most of the area surrounding Guarapari, and added most street names according to IBGE in the vicinity of Guarapari, etc.) Also it slows down my work with the INT-1 tags, as I am getting to a point where high technical knowledge of Inkscape and defining how much additional data should be availlable in the tagging preset, etc. Also while I am onboard it is limited how much I can test features with Go Map!! as the wireless data connection have limited bandwidth, divided by too many users,

The result have been that the last few weeks I have done random tracings, both Bing, and IBGE addresses, around Espírito Santo, mostly in the area of Grande Vitoria, but also some random edits further out. Closer to Grande Vitoria I have also worked my way around some landuse and natural landcover, getting woods and agricultural land as well as a little industry on the map. I hope that the increase in colours on the map can help recruiting more people to the project, and getting even more colour on.

Further, the more street names that get onto the map, the better routing works.

Also the more complete the map is with seamarks, the more value it gets as an alternative to commercial navigational maps for the hobby navigator. I know OpenSeaMap is actively working improving their interfaces and additional data layers such as harbour and marina guides, depth sounding database, etc. Looking forward to seeing the new base layer with more maritime friendly colours.

Yeah, and my possition is a little approximate, I am currently on vessel waiting in line to take fuel at a tanker moored in the southern Campos Basin, at Petrobras Tanker Mooring no 6 (bla bla bla yeah I know safety bla bla bla accident waiting to happen bla bla bla)

Back at work

Posted by Skippern on 18 January 2013 in English (English)

I am back at work, that means I will be able to do some more focused work.

The beta testing of an iOS editor (working name was OSMiOS, final name became Go Map!!) have allowed me to do random editing on lazy hours. As Go Map!! Is getting closer to official release (currently awaiting pre-release review by AppStore), and significant improvements done in the usavility of the app, I believe I can in near future have close to daily contribution to the project.

For the upcoming weeks I plan to continue my seamark importation, will complete coastal seamarks, and hopefully do a good impact on inland seamarks. Parallel with this I will improve my INT-1 tagging preset, mappaint style, and icon library, as well as some other preparations for other imports (still lot of work with IBGE Census addresses of Espírito Santo)

I will also if time permits, look at some documentation, such as continuing translation of Key/Tag wikipages to Portuguese, updating status on wikipages for areas I work, add more Brazilian information to SkipperGuide.com

There are preparations under way at OpenSeaMap.org to get a more nautical base map rolling, I am taking part in that process (this far mainly via mailing list, but also have submitted a MapCSS file for test purposes), I will continue on that process, either purely as a professional advisor, or more actively with edits to the style sheet.

Beta testing OSMiOS

Posted by Skippern on 29 December 2012 in English (English)

After leaving a comment in another diary entry here, I was contacted by the developer of OSMiOS, a new, and after a quick examination of features, probably the most complete OSM editor for iPhone and iPad.

I was invited as beta tester and promptly installed the necessary gadgets and the app. A first glance on it shows me that it is as close to a JOSM replacement on any mobile device I have used. The features I have missed in Mapzen POI collector and PushPin is included, at least as far as the developer have been able to date, and it also allows for bulk upload of changes (rather than in place of uploading each change on the fly, this editor actually work offline, just like the more complete editors we all are familiar with)

Another feature that looks promessing is that it allows for downloading Bing aerials for offline editing. That will be of good help when preparing for edits on trips where I know mobile coverage will be limited (see previous post). The only obstacle it doesn't overcome yet is where it is lack of Bing coverage.

Also, the tag presets is probably the most complete with regards of predefined presets, and if the tag you are looking for is still missing, there is an "all tags" tab that allows you to manually edit, add, and remove any tag, even those unknown to presets.

After less than one day testing, I am very much satisfied with the program, I have sent one feedback with minor topics to the developer, and as it looks now, this will soon be the closest to JOSM you'll get on any mobile device

An unexted holiday

Posted by Skippern on 23 December 2012 in English (English)

I have known for about a week that my main employer wanted to change my work schedule, but because of contract of the vessel I worked on I didn't expect to get home at all until February.

That suddenly changed, my vessel went alongside in Rio de Janeiro late Friday night, but this close to christmas air fares was impossible to get, resulting in VIP transport, 9 hour drive along BR-101, from Rio de Janeiro to Guarapari.

I used the opertunity to do a stress test of my new iPad/PushPin.

Upon departure from Triunfo terminal, near Pier Maua, and the access to the bridge Rio-Niteroi, my iPad was close to fully charged. I had forgotten the car charging plug at home, or rather left it with my wife as we have only one, I had no chance to charge my iPad during the trip.

I added features along the highway as I observed them, using the download feature to ensure I did not create duplicates.

I probably got half of the gas station along the stretch Niteroi - Casimiro de Abreu (shortly after there phone coverage is lacking, and when phone returns quickly bing coverage for support is missing)

I also got a few features on entry to Campos, but there also the battery died.

Conclision is that with current situation I can manage the stretch Rio-Macae or home-Macae without recharging. Getting another car charging plug will allow me a longer stretch.

For those not very up with Brazilian geography, Rio - Campos (the life of my battery) is about 600km, Rio - Macae and home-Macae is both roughly 400km (one slightly more than the other, difference less than 100km)

Upgraded tools

Posted by Skippern on 9 December 2012 in English (English)

During the last months I have been spoiling myself a little. I have upgraded my old iPad (first generation) wi-fi 16GB to a new iPad (fourth generation) wi-fi celular 32GB. That means I can access net on travels without the need of activating my cell phone as access point, so it opened some more opertunities to gather data.

I therefor did a heavy sort out of the programs I had on my old iPad, installing the ones I used a lot, the ones I would need for my job, and a few ones for fun.

When I tried to reinstall Mapzen POI collector, which I use on my android phone, and used a little from my old pad I could not get it installed (didn't find it in App Store), and looking for the other I had (OpenPOI), couldn't find that one neither, I ended up finding PushPin. I was happy to see that it used Bing! Images instead of Google (openPOI used google), and could swap to OSM Mapnik, also that it allowed to fetch existing POIs just like Mapzen POI collector, and with the latest update also allowed to edit POI areas (not limited to nodes) The only drawback with PushPin is that every edit comes as a separate changeset. I would love to see it keeping edits in same changeset as long as the changeset still is open, and allow me to customize comment field in the changesets.

The way PushPin get my GPS possition allows for me to quickly add POI's as we are driving (of course as long as I am the passenger) makes it possible for me to collect along the route, and not only where I stop.

What is missing now is a tool to pick up roads to add names and ref (could be included in next update of PushPin?) How I do this now is to edit the address in a POI along that road and than try to remember it so I can go back to the same place next time I open JOSM and correct the road data. This makes for delays, forgetting to correct all roads, missing important data, etc.

What I am loking for now is a routing/navigation app that allows for what I use OsmAnd for on my cell phone as I might swap my phone for an iPhone soon, I am in great need to upgrade my phone, and swapping to iPhone means I will no longer need to have two separate addresbooks, but loosing what I have from OsmAnd means I would still prefere an android for the time being (and since iPhone5 will be availlable in Brazil from end of next week there is a chance that I'll get one for x-mas)

Next week I will have time again to reassume some of the other maping activities, such as doing Bing tracings, seamarks, INT-1 symbols, MapCSS and JOSM presets, looking more at the new base layer for OpenSeaMap, etc

I have noticed that many roads traced from old Bing are slightly misaligned with the newer recalibrated Bing, which is more alligned with actual GPS traces, I think for most of southern Espírito Santo, shifting roads to allign them with new Bing will greatly improve accuracy of the map.

OpenSeaMap, INT-1 and a new base layer map

Posted by Skippern on 23 November 2012 in English (English)

I am glad to announce that I have been accepted as a team member in OpenSeaMap's attempt in making a more nautical friendly base map. We are still just starting the process, but at least it is a start.

The team at the moment is myself, Dominik, who does the testing with mod_tile, and Yohan, who for some time have been developing a houseboating site.

The three of us have the common goal of making a base map where typical land features are toned down, or maybe even completely neglected, in favour of enhancing the viewability of features that have an importance on nautical navigation.

I will use my place on the team to get the base layer as much influenced on INT-1 symbols as possible, though we might do some priorities on the side of INT-1.

Since we are just about to start off, it is still too early to say anything about actual results yet. Also, it has to be noted that there are a faction within OpenSeaMap that want a combined nautical and land map. My message to them is to continue to use the Mapnik base map, but as mentioned, we are too early in the process to know what will be the outcome of this yet.

INT 1 Tagging Preset and Documentation

Posted by Skippern on 26 October 2012 in English (English)

As a result of my reversed engineering of OpenSeaMap data model, I have gotten a lot further on both my tagging preset and my INT 1 documentation. I might need to do a cleanup in the tagging preset shortly, but at the moment, I'll focus on adding all the correct keys and values to the preset.

Next step on the preset will be to clean up the preset, getting the keys in logical order, with the values of combo and multiselect sorted in a logical manner (most used on top, the rest in alphabetical order?)

Some might have noticed that I create documentation pages for various keys and values as I continue on the documentation. That is because there are already usages of most of these, some times several thousands, and they are part of complicated schematics. I will try to make this as documented as possible. I hope that the team behind OpenSeaMap can go in and document some as well, that can help me go in the right direction both on the tagging preset and on the wiki documentation.

Reversed Engineering of Data Model

Posted by Skippern on 22 October 2012 in English (English)

It sounds strange, and should not have been necessary, but since the people behind OpenSeaMap havn't been much of a help of documenting their data model (a few scattered wiki pages with not much readable structure is not documenting). The result have been that I have looked through the tools they have provided (Harbor tagging preset for JOSM and OpenSeaMap Editor plugin also for JOSM), which have given me something more useful to work with, and than started to search for common values with taginfo. The result have been that I have managed to structure their data much better. Things I tag with my reverse engineered data model actually start showing up on OpenSeaMap, something that proves that I am getting closer to the data model.

There are still a lot of things that I cannot get around, though it might be missing from their data model altogether as well. Taginfo doesn't return to me commonly used combination to these tags, as they still havn't enough occurances in the database. That means it is hard to know how to distinguish different types of restricted areas from each other, for example.

Another thing I am wondering about is how to get notes on objects that can show up in separate information boxes depending on map presentation. At the moment I am using note=

My JOSM preset and MapCSS for INT-1 will be updated when I get a chance, probably in a months time (they have been heavily edited compared with the ones on my web page).

How to Contribute to OpenStreetMap in 5 minutes

Posted by Skippern on 14 September 2012 in English (English)

Catchy title?

User wille have made a poster [1] which gives an introduction into how to contribute to OpenStreetMap in a few easy steps. The one finished (actually he is still polishing on it on inputs from the Brazilian mailing list) product is in Portuguese, but he have an .svg source where the text easilly can be translated to other languages. I think this is a good idea, and such posters can be set up on collages where "tech-savy" people might study.

The project of cleaning up IBGE imported highways are proceeding with great speed. Many from the Brazilian community as well as other people intersted in helping are daily doing improvements, not only to the roads in question, but also to the surrounding areas. See my previous post if you are interested in that project.

Today I also added some port details near Rio Grande, where I might need to visit a ship yard in the near future. The details I focused on was to put enough information on the map that I might be able to route to it with OsmAnd. I hope it is included in the map befire I actually need to go there, OsmAnd doesn't update their maps too often.

Looking around the map today I noticed brownish yellow spots around several places in Espírito Santo. Did I really add that many farmland patches? I think I might have had some help. Are people starting to map landuse? I see that at least one of the foreigners helping tagging are adding landuse=residential so we are starting to add color to the map. I wonder if IBGE might have some sources that can speed this process? Europe have come a long way with Corine landuse data, and the US with some (TIGER?) data, why not look into doing some imports in Brazil as well?

I am starting to realize the ironic in the offshore industry. A ship equiped with an expensive remotely operated vehicle (ROV) install a two dollar toilet brush in one of its arms to clean a petrolium well hub at almost 2000 meter water depth.

IBGE (Re)Mapaton

Posted by Skippern on 8 September 2012 in English (English)

Some years ago, I think it was in early 2009, user Claudomiro imported IBGE highway data under PD license. At that time the Brazilian map was mostly blank, and except for a few, relatively small geographical areas, no high resolution imagry available. The import was welcome by the Brazilian community as it helped connect the dots (the areas with highres and/or active mappers) into one grid.

Now, in 2012, a large portion of Brazil is covered by high res images from Bing, more detailed imports have been done, the community have grown, data quallity in general is getting better.

With this improved data it has been noted that the IBGE imported data is of very low resolution, and some places deviates from the actual path by quite a large distance, users have at random basis corrected these paths until resently, when another user, Vitor Sessak (vitor1234) took the initiative to create an extract with the unaltered nodes of Claudomiro's import [1], and by an idea spurred by me we have started a (Re)Mapaton in order to get these last roads aligned as best we can.

Of corse I started out in Northern Espírito Santo where Bing coverage is quite good (some holes still missing though), and some alignment already done by GPS and other sources. Litoral South Espírito Santo is already fully aligned. The Caparaó region of Espírito Santo will be tricky to align as highres imagry is almost completely missing, and few gps tracks available.

For other states I havn't turned my attention yet, but seeing on the archive [1] I see that Minas Gerais, São Paulo, and Goias among other have a lot of non-aligned data.

If there is anybody else out there wanting to take part in our IBGE (Re)Mapaton, download the mentioned file, open it as a background layer in your favourite editor (I use JOSM for this), browse to an area with non-edited points and compare it with Bing, readjust the road if nobody else already have done it and upload your changes.

Vitor have said on the mailing list that he will update the archive, though it is not confirmed how regularly he will do so. The suggestion was weekly updates.

As the road network of Espírito Santo is improving I am thinking about making a complete list of ES-roads on the wiki, and create relations for at least all long and important ones. A complete list of BR-roads in Espírito Santo, and as well all of Brazil already are on the wiki, and most relations already have been created.

If you find my location strange, I am on Roncador oil field in northern part of Campos Basin off the coast of Rio de Janeiro, in the visinity of FPSO Frade (Chevrron/Frade oil field), FPSO Brasil (SBM for Petrobras), FPSO Petrobras 52 and FPSO Petrobras 54

Status update

Posted by Skippern on 8 August 2012 in English (English)

Its getting towards the end of my "offline" period, where I focus my attention on familly, and less on OpenStreetMap. I have during these few weeks witnessed the redaction bot (not many changes in my area), as well as been able to add a few objects through Mapzen POI collector (from my cell phone) and OpenPOI (from my iPad). The objects added is in Macae, Rio de Janeiro and Guarapari.

I also got a chance to try out routing with OsmAnd, and start to get results. Pedestrian routing worked fine in Rio de Janeiro, except that it didn't route me diagonally through squares, but along their edges. Don't know if this is a tagging or routing issue.

I will also familiarize myself with the access to some ship yards and other maritime structures, I was at Camorim yard and base on Sunday and Monday, and will in a few hours go to UTC yard, which will be introduced to the map during the following weeks.

Note: every time I sleep at a new hotel, or ieat at a new restaurant I try to add it to the map, though some might slip. Sometimes I add hotels and restaurants close to where I am, such as when I ate at Makoto restaurant, close to Praç XV, Rio de Janeiro, I also added two other restaurants next to it.

Comes to an end...

Posted by Skippern on 5 July 2012 in English (English)

My work period comes to an end, that means no more edit frenzies for some weeks as I have to spend time with my family.

For people reading here, and as a reminder for me for August/September:

  1. License Change Status around Vitória, ES, Brazil - Need to look into replacing a few nodes and roads. Roughly 20 objects need to be created.

  2. License Change Status around Cachoeira de Itapemirim, ES, Brazil One object affected, only the addition of one node in a road, I think we can survive if that node is deleted.

  3. Loads of Bing! coverage. Only the western most part of the south of Espírito Santo that really is in lack of coverage, though there are some holes and gaps around. Quite some cloud cover a few places, but anyway, some is better than none.

  4. Continue aligning my collection of Brazilian Hydrographic Maps, and maybe prepare for starting to trace this data.

  5. For the last few days my work have been focused on new Bing coverage, even though I have the source file for the Brazilian 2010 Census address data still laying around. More fun in tracing new roads than looking through the census data for street names. Though I can always fall back to that from time to time. Would probably be easier if I could arrange a paint style displaying street name and house number in each point.

  6. My INT-1 project are slowly progressing.

Gap in Minas Gerais

Posted by Skippern on 16 June 2012 in English (English)

Since I knew I would have problems accessing internet for a few days I downloaded all boundaries in Minas Gerais and did a little tidying on the border relations (created micro and meso region borders mainly), I discovered that there is a gap in the border between Ouro Preto and Mariana. Downloading the area with the gap, and there is certainly a gap, nothing connects or almost connects the two sides of the gaping boundary.

Somebody with access to the source data that can help fill in the gap?

Editing before going to work

Posted by Skippern on 11 June 2012 in English (English)

The bad thing about editing on the map before going to work is that I forget the time. I have to exit JOSM and unplug my hard drive as I use a public computer. If I have edited a too large area or starts the upload too late I risk that I have to either come too late to work or leave my hard drive connected to the public computer. Thankfully we are limited to only 20 people accessing those public computers, but still, I have some private stuff on that drive....

After the stunt with border relations in Rio de Janeiro state, I am now back on IBGE Census data for Espirito Santo, hoping to complete those parts of Presidente Kennedy that is not covered by clouds. I think I have one or two more days to do that. The question will than be if I continue with Itapemirim or Mimisa do Sul, but I'll probably decide on that first edit session after completing Presidente Kennedy. Municipalities of Marataizes and Vitoria had no valuable census data to import, and there are some municipalities not covered by Bing, I need to correlate the census data to Bing, or other background data to get it on the map, a slow process.

I filtered some garbage from the census data set today, removed all addresses consisting of only "RUA PRINCIPAL", "AVENIDA PRINCIPAL" or "ESTRADA PRINCIPAL" (main road). Keeping only data that have a streetname that make sense reduces the time editing alot.

Rio de Janeiro

Posted by Skippern on 9 June 2012 in English (English)

I suddenly got the idea to make border relations for all municipalities in Rio de Janeiro state. During this work I discovered some problems in the imported border ways, and cleaned up where I could understand the problems. Still, Sao Goncalo and Duque de Caixas municipality borders are broken relations (not forming complete circles) as there was lacking and conflicting data. Also it seems according to wikipedia that the municipality of Novo Iguacu have been divided into two municipalities, though I have no idea where the border goes.

There are some people importing IPP data for Rio de Janeiro, maybe they can look into this.

Also the border between Rio de Janeiro and Sao Paulo states need to be looked at as they are two sets of borders almost maching.

Data imports

Posted by Skippern on 8 May 2012 in English (English)

Finally thhe Brazilian comunity have been able to extract address data from IBGE 2010 census data, covering millions of points all over Brazil. Following a discussion on the Brazilian mailing list, this data have been devided by states and voluntairs from different states have received their part of the data.

This data have a few limitations:

  • the data is mainly covering rural addresses

  • there are lots of duplication in the data

  • data sometimes refer to entrance of building, entrance to estate, and even center of building

With these limits the import of the data must be done with caution. The preferred way after the discussion is to use the IBGE data in a separate background layer, and compare it with already existing data and Bing overlay.

Further I have been in contact with VLIZ regarding importing their EEZ/Maritime boundary data. They like the initiative, but are uncertain of what impact it will have on their userbase. My plan as I states in my contact with them is to do a one time import of their data, or even part of their data if they are not willing to release it all. They have also responded that they have some other data packages under development and might be willing to share some or all of it with OSM. I will continue to playnthis ball to see if we can get some benefiting data out of it.

For the rest of May I do not know how much time I have for OSM. Generally when I am at home my time is limited to diary entries and mailing lists, and to some extent some gps surveying, though there is little I can survey anymore as most streets have been traced. If I had time to do some walking paper I could get some street names in place (where IBGE data doesn't cover it, i.e. urban parts of Guarapari.

Bing tracing, INT-1 .svg, JOSM preset and mapcss

Posted by Skippern on 18 April 2012 in English (English)

The good thing about not having a specific project is that I can jump around on the map without feeling that I am delaying a specific import or project. This way I have now been able to add some residential roads in Marechal Floriano and Vila de Itapemirim, some random land cover in southern Espírito Santo, and gathered a bunch of SVG files I can use as base creating a complete collection of SVG icons for my INT-1 documentation.

The same SVGs are used in my INT-1 preset and mapcss for JOSM. I have by now all icons in chapter U according to British Admirality, US Hydrographic Institute, Brazilian Hydrographic Survey, French Maritime Administration, Canadian Coast Guard and Singapore Flag Administration. Mostly there are an agreement on usage of the INT-1 symbols from IHO, though there are some national variations. All national variations will be documented on the wiki, while I will chose the icons looking best for the preset and mapcss presentations.

In the future I will try to make a Mapnik style rendering based on INT-1 recomendations. I will follow the same base rule there as in my JOSM mapcss, chosing the icons looking the best.

At the moment I develop the preset and mapcss as well as edit new icons while at work (in my spare time) and upload changes while at home (due to somebody deciding to block ssh connections in the company firewalls). This makes for a long and slow debugging process, but hopefully the preset might be ready for an official listing in JOSM in not too long.

After completing the INT-1 preset I will start looking into making a Brazilian preset, where I collect tags and values agreed on by the Brazilian community, in order to assist in more consista t tagging in Brazil. This should IMO be done for several countries, not necessary to replace the default JOSM preset, but as an additional support to it.

All my .svg files are public domain, though some are derived from copyrighted material, all elements copied from other files are from PD licensed files, rest are drawed from scratch using only the copyrighted files as guide. No direct tracing of copyrighted files done.

ODbL

Posted by Skippern on 4 April 2012 in English (English)

Ok, so OSM is now under the new license, ODbL. Hopefully this doesn't mean much different for the contributors, and hopefully tha transaction to the new license havn't messed up too much.

In the last coupple of days I have gathered a few gpx tracks, and finally today got them uploaded to the server. I will within a couple of days look into getting some editing done, adding a few new features.

Among what have been explored is a german restaurant (Grossmutter), a tourist attraction (Fjordland) a zoo (didn't get the name) and a few roads. I also have the height warning of the viaduct in Linhares (the sign on the site says 5.20, but that is actually only valid for the lowest corner, I got to see more accurate measurements as it was in the process of approving a special road transport)

The tags I will use for the viaduct is maxheight=5.20 and maxheight:physical=5.20

With some of the roads I got around Pedra Azul I will be able to get a lot more out of Bing in the area, a large portion of one of the roads is so covered with trees that it is impossible to track from Bing. I hope the entire Rota de Largarta (thats the name of the road) can be traced now, previously only a few hundred meters have been traced.

Location: Avenida Atlântica, Macaé, Microrregião Macaé, Mesorregião Norte Fluminense, RJ, 27920-390, Brazil
