SceneryDesign.org I have made a new video tutorial that demonstrates the typical workflow I use to create autogen from OpenStreetMap data. In this tutorial I am creating forests, buildings and lights as FSX autogen. The tutorial also explains way to classify the buildings into types and categories, for example industrial or residential buildings.
Creating rectangles from a footprint
I have added a new processing step to scenProc, with this step you can replace a complex building footprint by a number of rectangles. The step only takes the filter of the objects you want to process as argument. So for example: REPLACEPOLYGONBYBUILDINGRECTANGLES|BUILDTYPE=3 It only works well on footprints that have many parallel edges, else […]
Features with holes (2)
Not so long ago I posted about added support to read features with holes from OSM files. Recently I learned that these changes slowed down reading OSM files more than 60 times. So I have removed this feature for now. Back to the drawing board, let’s see if I can find a more efficient way […]
OpenStreetMap, performance and more
In the next development release there are some interesting changes to the scenProc tool. These are the main changes: You can now read data from the OpenStreetMap XML format. This makes it even easier to use OpenStreetMap data to create autogen objects for FSX. By reading the OSM XML format directly you can get even […]
Autogen from OSM (2)
Tonight I was able to fix the remaining bugs in my tool to generate the autogen forests from the OpenStreetMap data. One of them was that I didn’t know that in the AGN file all polygons need to be closed (first vertex the same as the last vertex). Below are some screenshots of how it […]
Autogen from OSM
As I mentioned in my previous blog posts I am trying to create autogen from GIS vector data. For my first test case I am using the OpenStreetMap data of the Dutch island of Schiermonnikoog. Below you see a screenshot from the data, as well as a screenshot in the Annotator tool showing the autogen […]
OpenStreetMap rocks!
I had came across the OpenStreetMap project before, but only when I revisited it earlier this week the reail power of it struck me. Let me start with a little explanation about what OpenStreetMap is. It is a free Wiki world map as their slogan says. I has been created by people collecting GPS tracks […]
