Control Group

Each participant in the control group was assigned a number beginning with CG. For exapmle, the first participant was labeled CG_001. This formed the basis of the naming convention for all shape files relating to the control group.

The ouputs of the union tools for the control group were labeled U_CG_(control group #), and this convention was used for both the shape files and exported attribute tables.

eCognition Segmentation

There were four base rasters used in this output, and on one base raster we tried two different color parameters. This formed the basis for organizing the ouputs of the algorithms using the following naming conventions:

1. c0: These itterations were run on the simplified hillshade only, with no digital elevation model. The color parameter was set to minimum (0.1), but as there was no color in this raster we labled it "c0" for "color zero".
2. c10: These itterations were run on the simplified hillshade plus the digital elevation model using ESRI's Elevation #1 color stretch. The color parameter was set to 0.1, and the raster and subsequent ouputs were labled c10.
3. c20: These iterations were run on the same raster as c10, but with the color parameter set to 0.2.
4. c10BW: These iterations were run on the simplified hillshade (symbolized in blue rather than black) over the DEM using the standard black and white stretch. The color parameter was set to 0.1. Outputs were labled c10BW for "color 10, black and white."
5. c10PG: These iterations were run on the simplified hillshade over the DEM symbolized using a purple to green stretch. Color parameter was set to 0.1. The raster and subsequent outputs were labled c10PG for "color 10, purple to green"

All algorithm outputs were organized into the folders following the naming conventions above. The ouputs were labled using the following naming convention: Angamuco_Seg + (scale parameter) + (raster name). For example: Angamuco_Seg400c10 refers to the ouptut of the c10 raster with the scale parameter at 400.

Union results were classified using the following naming conventions: U + (scale parameter) + (raster name), so for example U300c10BW refers to the union results from the c10BW raster at a scale parameter of 300. Both the shape files and the exported tables from the union results followed this convention.

Additional files

The following names were given to other relevant files in the project:

Complejos.shp: This is the shape file for the original complejo map.
ComplejosGT.shp: This shape file contains a subset of the original complejos. It inclues only those complejos for which we have ground truthed survey data.
ControlComplejos.shp: This is the shape file for the complejos selected as part of the sample for the control group.
SamplePoints.shp: The centroids from the sample complejos used in the control group.
dem_sa.img: the digital elevation model.
hillshademean.img: The averaged "multi-look" hillshade.
