Re: [Talk-GB] How to map new housing?
Dave, As others have pointed out there is no particular way to do this, but I find that cycling round the roads with a helmet mounted video camera, speaking out the road names/house numbers as I go past. Often it takes a few visits to get everything correct, but even if it is not perfect it can still be helpful. The advantage I find with video is you get more context than still images. However I sometimes also use still images to try and triangulate the positions of parts I can't access, or upload to Mapillary to allow others to use them for other purposes. For building outlines, I usually just estimate the size based on the number of houses and the length of road from the GPS traces, offsetting back from the road by eye. I tend to draw simple boxes, rather than try and be too accurate. Once new imagery is available (every year or so), the size/shape can be tweaked.

Re: [Talk-GB] How to map new housing?
Field boundaries are often retained (development usually takes a field at a time), look out for these. They are a useful guide to aligning stuff with old aerial imagery.

Re: [Talk-GB] How to map new housing?
Hi Welcome to OSM. Mapping new developments is trickier without aerial imagery, but there's quite a bit you can do to make it more accurate than guesswork. * if you're mapping the roads use the GPS to walk down their centre, if it's safe to do so, of course) * Takes *lots* of photos. Videos are even better * If there is something already mapped in OSM Field Papers may help: https://wiki.openstreetmap.org/wiki/Field_Papers * I found that many new estates have a certain amount of conformity. Try offsetting a copy of the road centre lines to use as guidelines ensuring buildings equidistant from the road & the same width To map larger buildings you can walk walk around it taking waypoints with a GPS whenever you're in line with the plane of a building's side. These points can then have a way drawn with their opposite number to create the buildings outline. Make sure you're far enough away from it to avoid GPS interference.

It's a useful background on josm ... when combined with a GPS walk around. Planning applications are made available to the the public on the strict understanding that they may only be used for planning purpose. They generally contain maps which, if from digital sources, have a condition that all copies be destroyed after a year. Generally I would say that planning applications are not an acceptable source. Personally I think people put too much emphasis on building outlines, probably because they can be armchair mapped. Having housenumbers is, in my view, more useful, but less common. Unless you can convince the developer to contribute them, I would suggest that only old fashioned triangulation, or hiring a professional drone operator/commissioning aerial photography, are going to give you good information. I suppose you could laser scan, but the hire fees will be excessive. ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
Re: [Talk-GB] How to map new housing?
If you've got no imagery - basically you're stuffed for building outlines except for guesswork ( I tag these as "visual estimate" - sound a bit better). Digital Globe Imagery tends to have more new housing estates than other imagery sets .If you've surveyed an area just add address nodes Regards Brian On Fri, 8 Mar 2019 at 10:37, Dave Abbott wrote: > Hi, > > I'm quite new to OSM, and am wondering how I might go about mapping new > housing plots in my area. > > In general, there is nothing on the imagery - I know I can walk the new > streets and map them with GPS - but how to go about mapping the new > buildings? > > Is there a guide I can look at? > > TIA, > > Dave Abbott > > ___ > Talk-GB mailing list > Talk-GB@openstreetmap.org > https://lists.openstreetmap.org/listinfo/talk-gb > ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
Re: [Talk-GB] How to map new housing?
Hi Dave In general new housing is a bit of a best guess and a bit of creative use of gps traces. I use techniques such as walk the roads and cross over, or put a wiggle in, when I am level with the ends of the building. I tend to use those traces locally in josm as they will be a bit odd to someone else.

[Talk-GB] How to map new housing?
Hi, I'm quite new to OSM, and am wondering how I might go about mapping new housing plots in my area. In general, there is nothing on the imagery - I know I can walk the new streets and map them with GPS - but how to go about mapping the new buildings? Is there a guide I can look at?
