Graphical data formats
The FM-1000 integrated display uses the Environmental Systems Research Institute (ESRI) 3D shape-
file format for storing the layers of graphical information collected in the field (for example, spray
coverage, track logging points, and features). The three files in a shapefile set are:
l <filename>.dbf file: Contains the feature attributes
l <filename>.shp file:Contains position information
l <filename>.shx file: An index file that links the position information with its attributes
The term shapefile is used to refer to these three files collectively.
The display records all latitude, longitude, and height data in decimal degrees.
