Lab 04 - Ground Truthing and Accuracy Assessment

 

GIS 4035

 

 

In this weeks lab, I continued with the Pascagoula, Mississippi Land Use/Land Cover map that I created.  The class was to focus in on Truthing, and verifying that the data we surmised last week was true and accurate.  Utilizing Google Street Views I was able to look at sample site locations and determine if the classifications that I determined last week were in fact accurate.  Overall for this sampling I was 70% accurate when comparing last weeks assessments to this weeks samplings of the areas. 

 

In the above map, you can see my sample locations.  Those locations that I found to be of an accurate assessment were colored green.  However, if I looked at a sample location and found that the area represented in the classification was false, I symbolized the dot in a red.
