Replace building by rectangles updated

I have finished updating the algorithm of scenProc to replace building polygons by multiple rectangles. From the tests I have done for the Nantucket area I am quite pleased with the results.

I just spend most of tonight to type in the manual how the algorithm works, so I’m not going to repeat that here now. I would say just download the new development release tomorrow and have a good read in the manual.

Upcoming updates

The last weeks updates of my tools have been a bit slower than usual. On one hand that was because I have been busy with non-FS activities, but also because I have been experimenting a lot with creating autogen for Nantucket with scenProc. It’s useful to sometimes do some actual work with my own tools, that gives a lot of ideas for future improvements.

For ModelConverterX the highest priority new feature is to improve support for aircraft MDL files. But since I’m quite busy with scenProc now, it might take a few months before I will concentrate on ModelConverterX again. In the mean time I do try to fix bugs that are reported, but that also goes a bit slower than usual.

In the last week I have been working on improving the scenProc algorithm to split complex building footprints in multiple rectangles. I’m almost done with this update, I only need to implement one last improvement that I have in my mind now. After that I will have to update the documentation so that it is clear how to use this improved step.

I had hoped to finish this scenProc improvement by this weekend, but last week I had less time than expected. Next week we’ll go on vacation, so it might be I will only be able to finish it after that. So in that case you would have to wait a few more weeks…

Reading complex OpenStreetMap files

I got some error reports about the scenProc IMPORTOGR step. Sometimes it would throw an error that interleaved reading mode should be used. This mainly happened on bigger, more complex files. But when working on my Nantucket test area I also noticed that reading with certain required attributes stalled and got in some kind of endless loop.

I have now fixed both of these problems. So in the next development release it should be easier to use OpenStreetMap data in scenProc.
