I have an application that is able to import .lyr files into a Cesium map if they are bundled with all the required associated files in a zip file. The application treats the bundled files in the .zip file as a .shp file with its associated files. I want the application to import the .lyr file without having to bundle the .lyr file and other required files in a zip file. Simply the user selects the .lyr file and the application will retrieve the associated files and plot items on the map.
Is there an easy solution to uploading .lyr files this way into Cesium?
