some homes, fence and wide verge land at the top of morrell Avenue on oxford UK,EU. The accuracy is pushed abit with tree cover paralax Im tring to map to the base of the walls not the roofs remeber. The polygons can be impoved but I have data waiting for them and no one else got around to them yet...

indoor and street gazettering

Posted by Govanus on 12 June 2014 in English (English)

I've been using the indoor: system to Gazetteer flats in blocks either by outline separated with their corresponding layer/level data or just by entrance nodes were outlines are not clear to me yet.

In basic rendering the view is generally ignored unless you have a renderer that knows how to make a building plan in various possible styles from flat to isometric. big map renderers generally gloss over and ignore these but take the data into a spreadsheet or database and it gives a good postal listing like those that Kelley's used to make. As a data user this is more useful for me than say a number range especially when I try to add office or owner data into the Gazetteer which due to it being in osm allows it to be automatically to custom maps. It also helps navigation when the dwellings aren't sequentially numbered which is actually quite common (from both alterations and odd/even splitting schemes as well as say something that tries to combine floor and unit numbers from to separate ranges. The Gazetteer form just cuts though all of this and makes it straightforward and easy to work with automatically

Josm hasn't been so easy to work with for this needing a layer approach workflow to work and the online editors are very difficult to use with stacked features (think of a 40-story block of flats or halls of residence - the baseplan for most floors in the middle are likely to be very similar with most principle doors and loadbearing walls being in the same horizontal place on each one, with just layer/level/ele/height data to split them up). I have been thinking about writing a new editor to make things easier but I've had so much going on recently that I've surveyed a lot more than I've had time to add to osm lately, especially when I have to work in complex way without online editors, to get the data clear and without unwanted clashes of wrongly joined nodes.

Customised units and dwellings with variant layout features are also easy to handle like this.

-- In general Gazetteering is more useful for data users than large-scale mapmakers though interactive maps could highlight the important sub parts or jump into a building layer mode.

I read that is increasing use of osm to work in 3D on the wiki and the like. Describing where the dentist is on the 4th floor on the northern wing corridor, with these is easy this way.

In general I am adhering to the principles elsewhere expounded in OSM that: -the information provide and stored should not restricted or specially overly tailored to a specific purpose like a certain rendering engine or flight-sim such that it less useful for other users purposes. -If you don't like the rendering, change the render settings not the data per say, -if the render can't understand the difference between things add more differentiating information to OSM and not just remove things or worse deliberately remove detail such as for ways so they "store better on system x because no one renders under [arbitrary] zoom level y"!

It can be tough but it helps to make a general-purpose data set that can be used by so many people in different ways.

A useful set of slides explaining things about UPRN

Posted by Govanus on 10 May 2014 in English (English)

This is a link to a useful set of slides about how UPRN workthough the lifecyle of buildings and the agencies that get involved:

Remember old UPRN's never die they just get a cross-referance!

rececent change to parking tags

Posted by Govanus on 22 April 2014 in English (English)

revising mainly parking restictions. mentor prevously updateed the tags to parking lane routes but this along with illegal parking problems is likely to confuse, so removed it all to lok at more appropriate parking lableing. If parking at the side of a garage road you create a blockage problem either for turning vehicals on one side or blocking a garage door on the other. were garages face each other both sides block doors. The police have already athorised garage owners that they can leagaly tow or dispose of vihicals in front of the doors without any warning. The areas are laid to allow 24hr access for large vehicals to the garages. if now used in a storage mode then it is only a loading stop that can be made and you need to be ready to move out of the way. vandalisum and rouge parking has dammaged some low walls and signs and illegal parking followed. originaly parking on the main road on the estate was also banned but recently this began to be increasingly ignored by residents not wanting to pay for garages so now a large parking scheme has been introduced but not on the garage lands as they are private and not adopted highways. I'll need to rethink the original tagging as I suspect the original is likely to be mass retagged again without local knowledge if I just revet it back to private like a houses drive

osm text yet to be done completed and a quick method to add direct from text

Posted by Govanus on 13 March 2014 in English (English)

I have a couple of files in osm xml format I'm struggleing to find time to finish quickly and given thier stacking node nature they are tough to put up in stages. Some need polygon alignment but incase someone whats a preview I'll try to upload some of the small ones here:- <?xml version='1.0' encoding='UTF-8'?> <?xml version='1.0' encoding='UTF-8'?> <?xml version='1.0' encoding='UTF-8'?> <?xml version='1.0' encoding='UTF-8'?> <?xml version='1.0' encoding='UTF-8'?> <?xml version='1.0' encoding='UTF-8'?>

longcross

Posted by Govanus on 13 March 2014 in English (English)

some features at long cross. Site was a contry house and grounds then taken over by the milatary in later years used to test milatary vehicals before being used in closed rally sections and then sold to a film company. site had a golf course developed on in nr the fine original house probably by the army? there are a lot of stuctures for testing vehicals like tanks and lorries.

area still has unmapped features

I had another upload crash afewvhours back

Posted by Govanus on 18 February 2014 in English (English)

I upload about 23 simple changes to new house ways and after a long wait recieved the upload servers html error.

after a few attemps I' had to abandon the data and turn off for leaving all changes will need to be redone some time in the future.

Fixed railway land at Oxford that had corrupted nodes uploaded

Posted by Govanus on 17 February 2014 in English (English)

This land is loosely the land owned by Railway bodies like BRRB and NR. The BRRB section in the south near the Royal Mail office is being prepared for possible redevelopment, so the tags tried to reflect recent changes. The rail line was taken up in the last couple of years as part of the sale preparation process.

This is a really helpful looking document for working with addresses

Posted by Govanus on 14 February 2014 in English (English)

http://www.nlpg.org.uk/documents/LLPG_SNN_best_practice_v2.pdf

It covers UK numbering for flats and split use buildings and all the other special things that crop up.

It is used by parts of the goverment to do the same process that we do when adding addresses on OSM when they put them into thier databases.

Merchant's Railway -Portland UK,EU

Posted by Govanus on 10 February 2014 in English (English)

Tried to use the original (unpart updated) 1930's 25k map loaded to id editor along with bing aerial surface information and a few other sources to make a reasonable attempt at marking out the "Merchants Railway" on Portland that travelled quite far at both ends of its cable incline. Not actually sure but I don't think it was adverse to some trips carrying additional non-stone loads over time. But heavy stone was economic base of this and initially most railways reaching up to the top of the island. Local supply goods for other trades did begin to show signs of diverse future as the National rail network spread and gained more influence than sea traffic towards beginning of the 20th and end of 19th Centuries. The Navy and Prison service also utilise the rail capacity mainly around the coasts.

===

On the weekend I tried doing more infomation to Southfiled part as there is a suppriseingly large amount unmarked especialy in the large mixed use buildings. Also a the longest terrace of garages also needs to be finshed off too.

Weymouth dock railway.

Posted by Govanus on 7 February 2014 in English (English)

Did a lot of work to show the unused part tarred dual track railway that runs to Weymouth dock around by the river and under the american bridge. Note this is listed as active though unused till 2015 in NESA ver 11/05/2013. The fate of the line is dependant on rail operators requesting to use it. it was converted to single track but the old unused bit was just tarred over. now all is until reactivation. More tags could be added to clarify this state of affairs.

Gloucester Green Car park

Posted by Govanus on 23 January 2014 in English (English)

Was to be added as a continuation of the edit comments for tonight's drawing of Gloucester green carpark in Oxford.

The various offices stairwells plant rooms etc. are also yet to be added. Area was redeveloped in the late 1980's after failed attempts at the end of the 1970's and some major additional works were done at the beginning of the millennium.

Floods

was going to start something on high river marks here for regular flood areas but havn't time today. So maybe next time.

garage numbers at southfield pk colwey

Posted by Govanus on 6 December 2013 in English (English)

I started to look at the other half of the estate and it seems to have been tidied up with regard to number marking though many are marked in fading pen enough to make some logic to the scheme. It seems to follow a pattern relating almost to one garage to one flat with some left not so clear as the numbers have gone completely. As the flats where originally numbered on a numbering that best suited neat terraces with numbers jumping across the street (odds to one side and evens to the other) allowing a postman to walk down the street once and deliver all the letters when put in number order. Unfortunately that means that house numbers in Southfield park although theoreticaly still on opposite sides of the road are not really as close to each other when in numerical order anymore as whole blocks dozens of ten of meters away hold each half. There is a possibility that the garages run by the council were also once numbered in a similar fashion to the flats but where rationalised into the current scheme now going into OSM is also possible. the only two distinct garages on OSM from the private side there number too faded to read. When I dissolve the blocks made and add the missing ones then I can begin filling in the other scheme to OSM. I had hoped to go down to Cowley airfield to extend the council site designation scheme across a larger area but I've not had the time yet.

today

Posted by Govanus on 29 November 2013 in English (English)

tried to finish the area of highway on southfield park started yesterday unfortunatly tree cover on the arial shots made somebits hard to track on the ground its fairly smooth and constant width with the bays and turnings starting on the edje of this flow. The drive to southfield farm used to end at barracks lane so the continuation of batlemas close into the park was the official nameing as all the flats are named southfeild park,in their 1st address line the Bartlemas close became steadly droped so no official boundy exsists between the two but it lies anywhere alone the old drive to the 1st bend in an informal sense.

Tonights work on rail ref's

Posted by Govanus on 15 November 2013 in English (English)

this has crashed with a relation placeholder error when saveing and substatially regressed so wiill need to be redone - GW260 from NESA. It might look a bit complex but it is designed to still work when lines are cut up for features like bridges, level crossings and future midspan abandonments. the ref GW260 is a rail equivalent to nameing a road A34 so all the sub sections [of individual OSM ways] have a close relation to the ref (known as Routecode and LOR). I also put in a grouping level for named lines (traditionaly termed roads in the trade) along with there relations. this should still function when ways are split. I was going to add the speed limits but gave up today as they can sometimes very along a named line/road as well as chnage See NR info for latest speeds, till I think how best to mark them. OSM has what look like informal levelcrossings for footpaths along this stretch but NESA dosn't tell the train driver of them and you might be likely to by fined for tresspass!

GeoVRML

Posted by Govanus on 14 November 2013 in English (English)

Intreasting site to fold into my osm db useage.(http://www.ai.sri.com/geovrml/1.1/download/)

Maybe its reinventing the wheel but a mashup with mapcss, GeoVRML, OSMdata, kensi3D engine (in josm plugin) and some runtime intergration possibly with some html5 friendly version of ECMA/Java might give a {text-editor level(/maybe also by an html form element)} easily user maluable 3d render solution that could include multiuser realtime 3D interactive vectored MIcons and sound responces...

video inset signposts incoperated into kensi based landscape with mapcss colour and texture ques intergated: While users and deamon/bots feed info into the landscape (sea and rail traffic openseamap style [but fed with VRML ship models to annotate](and weather links...

For those wondering what happend to VRML97 in standerdised officialy at iso went though some impoving versions and then had the core effort pulled into making it like the xhtml effort at the same time to make it XML capatible and turned into X3D. Early bandwidth restrictions and some user awkwardness with dimlly lit models in cosmos made it lose widespread permanace as browser wars began to focus on pandering to the consistant visual layout Dreams of corperate marketing teams used then to still working in paper white than user definable world of html's 1-2. with big browser support week people gave up sticking to a standard and mainly evolved there own for use in things like games and more widely supported java/Flash filled the rest of the gap.

I think if people are putting the effort to evolve new things like mapcss that don't depend on a wide 3rd party browser support then loking at these older (fadeing from the mainstream memory) initiatives might prove useful to some. Software and algorithums are often already made and teasted (though admitadly some systems could benifit with some updateing of the old s/w to make it run on newer enviroments).

recent work

Posted by Govanus on 11 November 2013 in English (English)

Stopped mid way though seperating highway boundry from the main roadsurface as previous attempts to get the tagging right for wide compound road sites like this was makeing a confused mess. the road is getting an area likeat the north and the boundry and footway are yet to be seperated in the south end the result will render all parts in true areas (at bing sat accuracy) this I hope to then extend beyound the estate when finished.
