changes to my pavement entries and learning rivers

Posted by Govanus on 21 July 2014 in English (English)

I've found that for a time I've been picking the wrong term for pedestian pavements beside the main carrage way. In normal language i'd call these pavements, but for good and well explaind reasoning OSM decided to call them sidewalkd to avoid international confusion (pavement as a term has different meanings around the world). Knowing that I'd need to pick a differenet term I've been mistakeingly using footway by mistake (footways on some editors convert to footpaths) and I'm also begining question if some of my "Front Garden paths" should be footpaths or even private byways??? the problem is that what is simple to build with paving or a narrow strip of tarmac can be seen in different ways in osm but is physicaly similar and often used also used in very similar way too.

I'm intending to review the tagging I've done on sidewalks in a progressive manner.

I'm also looking at advanced bridge tagging to sort out some issues with some more recent entries. Bridges and rivers can become quite complecated when there is a lot going on like the Magdelen Viaduct/bridge (which has nine arches, 5 "tunnels" placeing places two river courses two-one embankment apontoondock and two sides, {not mentinon the multilane stuctures of the highway running over the top}!!!). I'll get there in the end but it might take some time. I've also been working on find details for the tasked missed off the last task listing and that is utility features like pumpsite and substations......

Current Activity List

Posted by Govanus on 25 June 2014 in English (English)

this is not exsusitive but outlines my work program for OSM:-

Finish adding CAB offical tags for OxCAB Finish suport services missing from OSM needed for CAB mapping such as third-party support and advice services. Add The Regional CAB sites following toward the rest of the organisation...

Compleat the records and relations to all the garages operated by the council in Oxford. as well as neighbouring others.

finish multilayer buildings for buildings at southfiled park and progressing futher out accross the city as suveying is done.[I've had more in notes for a ling time now]

Learn 3dPhoto-survaying to increase accuracy of Southfiled Park features.

Try to develop a decently accurate hight aware suvey technique to add public relm and communial lamps and secuity features across oxford [I done some preservey exploration to the centre of oxford and at southfiled park, hght will be important for the referance number to make sence as a lot are mount high on the side of buildings to avoid haveing poles]

Compleate the NPLG records gathered from lable surveys.[both Oxford City and the Vale of the White horse councils add them in codes on their bins....

compleate the transfer manually of refrances and route codes about railways from official sources like the NESA and line rental matieral [theis is helpful for users of live datafeeds and planning - there also is the issue of details of posaic nameing that passengers use but are different than the rail industry internaly] - Ialso have mapped these three different ways in the past some with some without the use of relations.

Need to review rail tagging especially when addingg the tracks/roads for each line to avoid logical errors being introduced.

Look at trying to expand highway areas [ I note some recetly became deleted and in the past people have not felt happy with how the tags define them [I was originaly working on the proposed standard but others seem to want to cover things differently so the standard went into dispute. the features I hope to work to add will be geting into the sub 1metre locational sensitivity level [wether I can get the coords absolutely accurate {using all technical meanings here} or to some relative approximation {more technical meanings used}] At this level road widths and edge shapes look very significant.

Look at fixing any errors and omisions to Wash Common [see previous work for location]

Look to chip in to work going on in Newbury as well as finaly getting multilevel models translated from pdf to OSM of the new centre of town developments and correting big interpretaion mistakes to the other shopping centres.

Do more work in andover and bradford.

work in Northumbria

fix problems in my previous work that I failed to get good location inputs for mainly from paralax, vegitaion cover, poor resurlution and lighting, and no clear fix points for base picture misalignments . What I fail on posstional accuracy I have hoped to makeup thematicly and with a sence relative layout sence.

Construction sites and other new changes needed.

improving detail like addeding relvent referances, addresses and surfaces etc.

add referance numbers for offical rights of way.

Add 3d data when understood and availble.

map out the parking restictions in oxford and Newbury. including on developing the clausual deffinitions.

develop bosme

various activities overseas

look at adding NUTS and LAU to Europe.

add offical language translations to various sites [such as russion arabic and chinese forms]

add more thangs I notice are missing....

Well thats a lot to work on for a while. So if it looks like I scattering about and leaving nothing finished then its probably competeing for time with these ares with equal urgancies.

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.

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.

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.
