Description:
Abstract:
This data set contains four general land use/land cover (LULC) classes — excluding clouds and shadows — for the Southwestern Intensive Study Area (ISA) of the CPC Ecuador Projects, in the northern Oriente of Ecuador.
Purpose:
Population-environment interaction research requires accurate LULC data for a variety of time periods. This data is used to determine the spatial structure and pattern of land use throughout this ISA.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attribution of the pixels is based on a combination of the classification algorithm and informed decision-making by the analysts. Accuracy of the classification has not been determined.
Logical_Consistency_Report: Not applicable
Completeness_Report: Not applicable
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Horizontal accuracy is within 0.5 pixels of the true location. Therefore, the accuracy is +/- 15 meters.

Source_Contribution:
The Landsat TM image provided spectral information which was used to identify distinct LULC types in the classification process.
Process_Step:
Process_Description:
An 255-cluster ISODATA unsupervised classification was performed on the Landsat TM image.
Process_Date: 2000
Process_Step:
Process_Description:
Using Transformed Divergence and a minimum divergence of 1950, the 255 clusters were iteratively reduced to 30-40 spectrally separable clusters.
Process_Date: 2000
Process_Step:
Process_Description:
The resultant 30-40 spectrally seperable clusters were entered into a maximum-likelihood supervised classification as training data.
Process_Date: 2000
Process_Step:
Process_Description:
The CLUMP and ELIMINATE processes in Imagine were applied to the supervised classification output to reduce noise in the image.
Process_Date: 2000
Process_Step:
Process_Description:
Classes were assigned to the 30-40 cluster supervised output using ancillary data and expert knowledge of the field site. Clusters belonging to the same class were then recoded to that class number.
Process_Date: 2000
Process_Step:
Process_Description: The Imagine .img file was exported to an ESRI grid format.
Process_Date: 2000
