Description:
Abstract:
This data set contains 20-meter elevation contours for the Southern 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.

Overview_Description:
Entity_and_Attribute_Overview:
Attribute items are in typical ARC/INFO arc format. Attributes requiring additional explanation are: TYPE – 1 indicates that the contour elevation is a multiple of 100; 2 indicates that the contour elevation is not a multiple of 100 CTRLINE – The elevation value of the contour, in meters
