1 Answers GPS-practical

2 Determine length of track (1) Add a attribute to the attribute table Accuracy = cm?  Scale 2 Maximum length = 10 km?  Precision 5 + scale (2) = Total precision: 7

3 Determine length of track (2)

4 Determine distribution among topography classes Question: How many points fall in each topography class

5 Step 1: join the information on Topography to the GPS points Determine distribution among topography classes

6 Step 2: Determine frequency of topoclass

7 Determine distance from pond to the 10 closest marked waypoints 1: Export/Select the pond –Select the pond from the layer “Top10GPS” –Rightclick the layer “Top10GPS” –In the menu select Data  Export

8 Determine distance from pond to the 10 closest marked waypoints Join (Spatial) pond to waypoints Select GPSpoints  add join

9 Determine distance from pond to the 10 closest marked waypoints
