Which band is referred to as the SAR workhorse and is good for global mapping and change detection. 

Which of the following is not a type of change classification scheme?

The spatial resolution of radar data is directly related to the ratio of the sensor______ to the length of the sensor’s ________.

In image differencing, a value close to zero indicates what?

If you were to perform change detection using two different map classification schemes, what would the results be?

SAR uses an active sensor, so it produces its own energy. 

Factors for collecting good reference data include? Select all that apply.

When assessing map accuracy, it’s important to consider both positional and thematic accuracy.

A thematic map accuracy assessment uses an error matrix.

The positional or thematic accuracy of a map must be measured against what the map is going to be used to accomplish.
