Access_Constraints:

Data is available to the public, made possible through the NASA LBA program.

Use_Constraints:

There are no use constraints. However, potential users should be aware point elevations should not be used alone to create a digital elevation model, as the accuracy would be very poor.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: Attribution was based on the elevations assigned to points on the source map. There is 100% agreement for attribution between each digitized point and its source point. Accuracy of the attribution is dependent solely on the accuracy of the data source.

Logical_Consistency_Report: Point topology exists.

Completeness_Report: Data are complete for the ISA.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: Horizontal accuracy is assumed to be within the NMAS standards for a map of this scale.
