- Description:
-
- Abstract:
- This data set contains 20-meter elevation contours for the Northern Intensive Study Area (ISA) of the CPC Ecuador Projects, in the northern Oriente of Ecuador.
- Purpose:
- The elevation contours are used, in conjunction with point elevations, to create a raster digital elevation model (DEM).

- 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 of possible ramifications of using the contours to create a DEM of too fine a resolution, given the interval of the contours.

- Data_Quality_Information:
-
- Attribute_Accuracy:
-
- Attribute_Accuracy_Report:
- Attribution was based on the elevations assigned to contours on the source map. There is 100% agreement for attribution between each digitized contour and its source contour. Accuracy of the attribution is dependent solely on the accuracy of the data source.
- Logical_Consistency_Report: Arc 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.
