Description:

Abstract:: This data set contains the boundary of the Southwestern 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.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report: No attribution was assigned to the data.

Logical_Consistency_Report: Polygon topology exists.

Completeness_Report: Data set is complete.

Positional_Accuracy:

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:: Four 1:50,000 topographic maps were identified as the larger area containing the ISA. The ISA extent was selected to be the full north-south extent, and lie centered between the east and west extents, of the four topos. The coordinates were recorded as follows. The latitude coordinates were taken from the four corners of the four-topo group. The longitude coordinates were recorded as the coordinates lying at the central east-west point on each topo map. These four coordinates were recorded in latitude/longitude.
Process_Date: 2001

Process_Step:

Process_Description:: The latitude/longitude coordinates were converted to UTM, Zone 18 South coordinates.
Process_Date: 2001

Process_Step:

Process_Description:: The four UTM coordinates were used to generate a boundary polygon for the ISA.
