Scanning |
Scanning is a digitizing method that converts an analog map into a scanned file, which is than converted back to vector format through tracing. Acquiring much quicker alternative to manual digitizers for digitizing existing maps are to be considered which are to be finding in a scanner. A scanner can converts an analog map into a scanned image file in raster format.
Map features are shown as raster lines, a series of connected pixels on the scanned files. To complete digitizing process, a scanned file must be vectorized. Vectorization turns raster lines into vector lines in a process called tracing.
