- Description:
-
- Abstract:
- Hydrography coverage for the northern Oriente region of Ecuador. The hydro network was digitized from a 1:250,000-scale topographic map.
- Purpose:
- The primary purpose of this data set is for cartographic representation in small-scale maps of the hydrographic network in the Oriente.

-
- Attribute_Accuracy:
-
- Attribute_Accuracy_Report:
- Attribution was based on the topographic map legend. Accuracy of the attributes is dependent solely on the accuracy of the data source for the original map. Level of accuracy is indeterminite.
- Logical_Consistency_Report: Arc and polygon topology exist.
- Completeness_Report: Data set is complete.
- Positional_Accuracy:
-
- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:
- The data set was digitized with less than a 0.01 RMSE. It is assumed that the topographic maps are compliant with the US National Map Accuracy Standards, giving the hydro features no more than a 125m horizontal error.
