Note on Compatibility

We strive to provide universally compatible GeoJSON files, but sometimes a mapping application may require a specific coordinate reference system (projection) or particular data fields. If your file doesn't load or display as expected, please get in touch. We can reproject the file, add additional data columns to the polygons, or even develop a custom mapping tool—whether simple or complex—to ensure your data visualizes correctly. We won't rest until everything works just the way you need!
