7. Map Tile Reference System Map Tile Reference System: The parcel reference system for each county is subdivided into rural tax districts and corporations, which are further subdivided into map tiles / map sheets. The type of parcel reference system is determined by the primary map scale (usually 1”=400’ scale) configuration for rural maps and its relationship to urban areas (usually 1”=100’ scale). WVAGP Tax Map Workshop 10 June 2009 Counties have different reference systems based on the original mapping Primary map tiles Nested Grid True Grid Modified Grid Random Orientation true north Y Y Y N Uniform tile size Y Y N N 100 scale nested within 400 scale Y N N N
