Re: [OSM-talk] finding overlapping buildings

I don't have an interest in buildings as such what a lot of my mapping is concerned with validating HOT projects. I generally sit on three and check the work as its done. Working like this I can catch new mappers making mistakes and give them gentle feedback to get the overall quality of mapping

Hi Frederik, I tried with the area I provided as example in Bali. Interesting to learn that we can export a group like that to JOSM for editing / correcting.See this zone https://www.openstreetmap.org/#map=17/-8.447237794027034/115.40394650097596 As I said in a thread for Maproulette, QA tools

Re: [OSM-talk] finding overlapping buildings

Re: [OSM-talk] finding overlapping buildings

Very nice. The process I'm using is run it to find the rough area that contains duplicate overlapping buildings. Then redownload the area so its fresh. Then scroll through the buildings. Sometimes one is beeter tagged and more accurate than the other so you really do have to scroll through them

With Osmose you can also get only large building intersection by filter on severity http://osmose.openstreetmap.fr/en/map/#zoom=11&lat=49.9788&lon=8.3169&layer=Mapnik&overlays=T&item=0%2C8300&level=1%2C2&tags=&fixable= Or addressee the class 2 only. http://osmose.openstreetm

Re: [OSM-talk] finding overlapping buildings

John, Pierre, I made some improvements to the select duplicate buildings script. It now uses a spatial index, which makes it a lot faster on large datasets. It also now uses the actual area of the buildings and their intersection, as opposed to their bounding boxes. I will work on your other reque

Re: [OSM-talk] finding overlapping buildings

Thinking it through I can already select buildings then validate for crossing ways. Dump the selection in a new layer and save it. Restart JOSM to clear the memory then load up the saved layer and the todo list. I can even chap down the number loaded into the layer. I think this is workable. U

Re: [OSM-talk] finding overlapping buildings

My gut feel is as simple as possible especially when dealing with larger areas. I loaded a 215 kb file into JOSM and found 181 duplicated buildings but after dumping them in a todo list JOSM seemed reluctant to delete them one at a time. Could it work through a selected area? There is already a

Re: [OSM-talk] finding overlapping buildings

I am not sure what is already included in JOSM validations, but with orthogonal and Duplicates, we cover most of the  newbies tracing buildings problems that we can automatically spot analyzing the data. Others would be about dimensions that exceed normal building size, this including big insti

Re: [OSM-talk] finding overlapping buildings

I have a fix for the speed issue, but need to test before posting. There is also bug with how the overlap is computed. Do you want both tests in the same script? I could include "building ways with unclosed area", anything else? On Fri, Nov 24, 2017 at 4:14 PM, Pierre Béland wrote: > Ok > > for

Ok for the script, I simply commented the console print message and it does work. Great if developpers could collaborate to improve this as a Building Validation plugin. It could include other features such as building ways with unclosed area   Pierre Le vendredi 24 novembre 2017 18:03:4

For a small number it works well. When faced with a sample with a thousand buildings it takes a little longer. The real test is how do you cope with a 2 mb file of OSM data containing a few thousand buildings? But having said that what you can do is if you spot one then download the surrounding
