| HOWTO: Display GPS Data. |
|
 Summary
| |
This document describes how to use LayerTrackLog provided in TalMapX Control.
With this document, users can display GPS data more efficiently using LayerTrackLog.
|
|
|
Steps
| |
1. Get Control Manager from TalMapX Control.
2. Get Layer Manager with the Contorl Manager.
3. Get LayerTrackLog with the Layer Manager.
4. Assign the data to the created Layer Object to show the GPS data.
