Create network creation script & Update Pixi Environment With Geospatial Packages

[SWRIganderson]

I have created a network generation script that will create ALTRIOS networks from open data sources. The inputs are two layers in a geopackage. An example geopackage is in the resources/networks folder as an example. The layers are a polygon with defines the regions and a point layer that defines the destinations.

There are few problems to solve yet and items to check.

1. Pixi environment is not working right. I have tried running this through command line and vs code with no luck.
2. Does NetworkBuilder.py belong in the resources/networks folder?
3. Should the example usage of it create a folder in a different location?
4. We need to remove the environment.yml file from the networks folder before approving this.

I wanted to get this drafted so we have it on the radar.

Technical Requirements

• Must generate networks for US (lower 48 states)
• Pull OSM data automatically
• Pull DEM automatically
• Filter DEM to a reasonable level
• Apply speed limits based on user input for mainline and sidings
• check generated network for problems
• report coordinates with problems
• Needs to run on Linux and windows
• get up to PEP8
• Create documentation

Problems/Tasks

• Need to solve GDAL generating error messages which seems to be pixi related
• Need to get speed limit application on sidings and define the input format. Currently applying constant speed limit to entire network.
• Need to integrate network checking and error reporting functionality with Network Builder

@calbaker Well it worked on my computer........

@calbaker I'm not 100% sure what is happening here. It looks like it failed while downloading the elevation data. Could you tell me what folders got created in the elevation data folder? If you have folders with tiff files in it, can you send me the file size for those folders.

The co_..... folder for me is 50.7 GB. The tx_..... folder is 62.0 GB for me. This may give us some indication if there was a partial download of the data. If there is a partial download, the problem may be in the seamless-3dep library. It may be worth commenting out the build_network() call down at the bottom and just call the download_elevation() method if there is a partial download of the elevation data. If you see a couple files with a .vrt file extension, the elevation data download did not complete. I hope this is not a mac specific problem.

@calbaker This may be a rasterio problem. seemless-3dep uses rasterio. This issue below looks to be similar, but I have not read it in detail yet.
