- Geospatial_Data_Presentation_Form: raster digital data
- 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.

- 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.
