I have .mdb file ( Microsoft Access file ) which appears to be a shapefile index ( snapshot as attached ) and i need to get longitude and latitude from this so that file can be fed to Tableau or PowerBI for visualization purpose.
IdxOriginY values in
GDB_GeomColumns for your table first.
Then, multiply the
MaxGY values with the grid size and add the origin values. You'll end up with the min/max coordinates in the projected system. You can convert the coordinates into lat/lon values using Proj4.js or some other tool.
