Creating Map Files - GPS TrackMaker Reference Manual

6.4 Creating MAP Files

MAP files are non-editable maps that open very fast on background of the screen. To see the characteristics of
MAP files, take a look at the topic Overview.
The steps to create a MAP file are:
- Create a map with the Drawing Tools.
- Apply the appropriate level of zoom to each drawing element.
- Each Tracklog may have up to 4000 track points. For polygons (filled Tracklogs) with more than 4000 points, use
the Rectangular Clipping Tool to reduce the number of points. For lines, use the Tracklog Reducer Tool .
- Divide the Tracklogs considering the size of segments. Separate the Tracklogs with big segments from Tracklogs
with small segments. For further information, see Accuracy of MAP Files.
- Select all Tracklogs and use the Homogenize Tool.
- Configure the Map Properties.
- To save in MAP format, click on Files -> Save File as -> and choose GPS TrackMaker Map Format.
Important: After created, MAP files cannot be imported to be edited. So, they cannot be used to replace GTM
files. It is always recommended to save a copy in GTM format for future modifications.
