What is Covertype dataset about?
The Forest CoverType dataset
- Title of Database: Forest Covertype data
- Number of instances (observations): 581,012
- Number of Attributes: 12 measures, but 54 columns of data (10 quantitative variables, 4 binary wilderness areas and 40 binary soil type variables)
- Attribute information: Given is the attribute name, attribute type, the measurement unit anda brief description. The forest cover type is the classification problem. The order of this listing corresponds to the order of numerals along the rows of the database.Name Data Type Measurement DescriptionElevation quantitative meters Elevation in meters Aspect quantitative azimuth Aspect in degrees azimuth Slope quantitative degrees Slope in degrees Horizontal_Distance_To_Hydrology quantitative meters Horz Dist to nearest surface water features Vertical_Distance_To_Hydrology quantitative meters Vert Dist to nearest surface water features Horizontal_Distance_To_Roadways quantitative meters Horz Dist to nearest roadway Hillshade_9am quantitative 0 to 255 index Hillshade index at 9am, summer solstice Hillshade_Noon quantitative 0 to 255 index Hillshade index at noon, summer soltice Hillshade_3pm quantitative 0 to 255 index Hillshade index at 3pm, summer solstice Horizontal_Distance_To_Fire_Points quantitative meters Horz Dist to nearest wildfire ignition points Wilderness_Area (4 binary columns) qualitative 0 (absence) or 1 (presence) Wilderness area designation Soil_Type (40 binary columns) qualitative 0 (absence) or 1 (presence) Soil Type designation Cover_Type (7 types) integer 1 to 7 Forest Cover Type designation
