A good base point is one that is located on a flat, preferably paved, surface. Once a base point is marked, the Viewer will assign a color to the base point to represent it’s accuracy:

• A base point showing in green is one that is considered to have good precision.

  

• A base point showing in yellow is one that is considered to have adequate precision. Results will probably be okay, but consider using the undo button and selecting a better base point.

  

• A base point showing in red is one that is considered to have poor precision. Use the undo button and select a better base point to avoid inaccurate results.
