ER Mapper Vector
ER Mapper Vector is an vector image file format associated with the ER Mapper and ER Viewer products currently owned by Hexagon Geospatial. "ER" stands for Earth Resource.
It consists of a text-based .erv file containing image attributes and metadata, and another file (usually with no extension) containing the image data.
The .erv file likely begins with a line that reads "
DatasetHeader Begin", and contains a line that reads "
DataType = Vector".
