This is an app that gathers the freshest copies of all the parcels in Washington State using primary data sources.
The state publishes a yearly parcels snapshot.
This project has the same goal, but rather than a one time snapshot this app will give you the freshest parcel data everytime it's run.
Right now we don't have complete coverage of all the counties in Washington state.
If you know a GIS person that works for any of following counties please convince them to publish their parcel data on the web.
- Adams
- Asotin
- Benton
- Columbia
- Cowlitz
- Franklin
- Garfield
- Klickitat
- Lincoln

Note: You can also run this from command line or VSCode if you have the latest version of dotnet installed by setting the current directory to this project and using the "dotnet run" command. There's no platform specific code in this project so it should run on MacOS and Linux without modification although this has not been tested.
If you find this project interesting or helpful please let me know.
- Use GDAL's ogr2ogr to merge all of these shapefiles into a single file.
- Use tippecanoe to create a vector tileset from this parcel data.
- Use Protomaps to create a static tileset and display it in a map on the github pages site for this repo.
