- Description:
-
- Abstract:
- This data set contains the boundary of the Northern Intensive Study Area (ISA) of the CPC Ecuador Projects, in the northern Oriente of Ecuador.
- Purpose:
- Purposes include delineation of the ISA on maps, reference for the clipping of larger data sets, and as a physical limit for selected analyses.

- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:
- The selection of the boundary for this ISA was initially an arbitrary decision. There is no relationship between this boundary and any real-world features. The location was based on the latitude/longitude coordinates of two topographic maps, and as such, the horizontal accuracy is considered to be absolute for the purposes of this data set.

- Process_Step:
-
- Process_Description:
- Two 1:50,000 topographic maps were identified as the desired area for the ISA. The upper corner coordinates were identified for the northern-most map, and the lower corner coordinates were identified for the southern-most map. These four coordinates were recorded in latitude/longitude.
- Process_Date: 1999
- Process_Step:
-
- Process_Description:
- The latitude/longitude coordinates were converted to UTM, Zone 18 South coordinates.
- Process_Date: 1999
- Process_Step:
-
- Process_Description:
- The four UTM coordinates were used to generate a boundary polygon for the ISA.
- Process_Date: 1999
- Process_Step:
-
- Process_Description:
- The northern boundary of the ISA was clipped to fit along the Rio San Miguel, the river which is the border between Ecuador and Colombia.
