The resulting vector map, sometimes called "an arrowmap" roughly mimics those currents under the surface which are parallel to the surface, which produced the field.
There are generally recognized to be two major sources of error when converting vector maps (either paper or digital) into gridded or raster format.
The road database is a vector map of some area of interest.
These echoes have to be displayed together with other real world data like object positions, vector maps and satellite images in a consistent way.

All raster- and vector maps are fully editable.
The raw information - geographic coordinates of latitude and longitude - is stored with other essential details as a data file called a vector map.
All of this data could be overlaid on hand-drawn vector maps.
