Coordinate System of Data For Publishing a Web Mercator Vector Tile Basemap

ErikBreedon

I intend to create a vector tile basemap from my own data. My data is stored in a state plane coordinate system (I'm in USA) because most static maps created with that data will be displayed in state plane coordinate system. However, I intend to publish the vector tile basemap using web mercator because I want it to be compatible with other services in web maps.

Is it OK to store the data in State Plane but simply publish the vector tile basemap in web mercator?

Thank you.

Hey @ErikBreedon 

This is a pretty common method to doing exactly what you're wanting to do, ESRI has a method called "projection on the fly" and it ensures that the data is drawn in the maps coordinate system, even if it is still stored in other coordinate systems. There may be distortions occasionally, but typically they're pretty minor, I would try to publish a very small test dataset in this format, observe a use case, and then once satisfied, publish the rest!

Edit, here's a link to the projection on the fly page: https://www.esri.com/arcgis-blog/products/arcgis-pro/mapping/projection-on-the-fly-and-geographic-transformations/#:~:text=ArcGIS%20will%20always%20apply%20projection,data%20on%20your%20map%20otherwise.
