  1. Hello, thank you for your answer. As long as I understand, the method you suggest me to us requires to draw the buildings manually and this is not what I am looking for. I need to run a simulation for the whole city and drawing the buildings (even using bitmap in bakcground) will take it forever... I was actually looking for a method, that i described in WallMan manual in 3.4.3 Convert Urban Database from Scanned Map Data. If my understanding is correct I only need to upload a scanned map image (which I get as png from QGIS) and the Pixel Converter will do everything for me. The quiestion is "how to do it" when Pixel Convertor is greyedout? Thanks!
  2. Hello, can someone help me to create an Urban Database, based on a scanned map data (as described in WallMan manual)? Since I can't create a database from a shapefile, I have decided to do it in another way: "Convert Urban Database from Scanned Map Data". For this, I have opened the shapefiles in QGIS and saved a black/white image without any unwanted parts. I first create an empty Urban Database and choose "Draw manually". Then I go to File / Convert Urban Database / Pixel Database and it's grey and NOT clickable... I have found previously that in order to a Preprocessing for a Database, you need to close it, then open again as a new project and only then you will be able to do preprocessing: I was wondering, maybe it is the same thing here? I can't really figure out how ... Any comments much appreciated! Best regards, Yaroslav Smalko
  3. Hello, I am now trying to import shapefile to a WallMan in order to build a 3D model for propagation computations. During the import i get an error I can't figure out what exactly the programm doesn't want to except, because when I use another files, which have the same structure it works... Can please someone explain to me what the shapefile should contain in order to be succesfully import to WallMan? The shapefiles I also add for you: - the first one (file1) is the actual file I have and need to use (contains more information) - the second one (file2) is the one I have downloaded from the internet, looks simpler and still does not work well - the third (file3) was again downloaded from the internet but for some strange reason sucessfully imported by WallMan Best Regards, Yaroslav file1ImportError.shp file2ImportError.shp file3ImportSuccess.shp
