Module1.2

 

For this module we measured the accuracy of two street shapefiles using created intersection points against orthophotos reference points. Use the “compiled to meet” statement below when the above guidelines for testing by an independent source of higher accuracy cannot be followed and an alternative means is used to evaluate accuracy. Report accuracy at the 95% confidence level for data produced according to procedures that have been demonstrated to produce data with particular horizontal values:

ABQ_Streets_Sample

Compiled to meet 23 feet horizontal accuracy at 95% confidence level

StreetMapUSA_Sample

Compiled to meet 217 feet horizontal accuracy at 95% confidence level
