Extracting ESRI Shape files

E-mail Print PDF
Standard ESRI shape files can be generated from the NZ Open GPS Project's source files.

1. Download the Source files of each map area from

2. Wait while files download

3. You will need a copy of cgpsmapper from - the freeware version will do fine.

4. From a command line type:
cgpsmapper SHP where MapfileSource = the name of the source file to create ESRI shape files from

5. Cgpsmapper will process the file into standard ESRI files (WG84) which can then be used in map GIS applications.


Polygon.shp (and associated .shx and .dbf) contain polygon level information like water, oceans, buildings, airport runways etc

Point and POI.shp's (and associated .shx and .dbf) contain point level data

Line.shp (and associated .shx and .dbf) contains the roads, track, and ferry level data etc

Note that if you process another source file, the shape files will be over-written so best to move them to another directory once you have done the conversion.

Much of the data in the maps has been user created / modified, but is based on LINZ data - license below:
