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.
These are probably easting/northing values so it depends on where the data is on the globe. To get Longitude Latitude you need to transform it and for that, you need to find out the projection system. You can use QGIS with OpenLayers plugin to help in locating the points in the basemap.
you have to project them to latlon system. QGIS can project to latlon system.
