The 2005 Kansas Land Use/Land Cover Mapping Initiative was a two-phase mapping endeavor that occurred over a three-year period (2007-2009). Concurrent with mapping the state of Kansas, the Kansas River Watershed was also mapped. The Kansas River Watershed extends into southern Nebraska and includes a portion of eastern Colorado. During Phase I a Modified Level I map was produced. In Phase II a series of maps, Modified Level II through IV, were produced.

To use the ArcMap document, unzip the downloaded file to the desired location and open the .mxd document within the extracted folder. The .mxd document maintains the links between the source data files and the layer file that defines the land cover names and colors. These links are stored as 'relative links', meaning the folder can be placed anywhere and still work so long as the files remain within the folder. Individual data files can also be copied from the folder and moved around; simply apply the layer file (.lyr) to the source data files (Layer Properties --> Symbology tab --> Import button in ArcMap 9.3.1) to use the color ramp provided.
The KLCP 2005 data are clipped to several different extents, please consult the ReadMe.txt file or metadata for specific information. Multiple buffer distances are included, this was done to offset potential 'edge effects' in spatial analysis; additional explicit state and county boundaries are also included.
1990 KLCP - Level I Update Data:
As part of the KLCP2005 processing the 1990 Kansas Land Cover Map (KLCP1990) was reprocessed to match the KLCP2005. Information about KLCP1990 project and links to download the new GIS data can be found at the KLCP1990 Research Page.
The goal of Phase II was to map subclasses for grassland and cropland, classes which were mapped during Phase I. For the Level II map, cool- and warm-season grasslands were mapped along with Spring Crop, Summer Crop, Alfalfa, Fallow, and Double-Crop classes. For the Level III map, the Summer Crop subclasses Corn, Soybean, and Sorghum were mapped, and the Spring Crop class was reassigned to Winter Wheat. In the Level IV map, irrigation status was mapped and added to the Level III crop type map. The land cover maps were clipped by watershed and state boundaries. The Kansas Land Cover Patterns Level IV map contains twenty-four land use/land cover classes and has a positional accuracy and spatial resolution appropriate for producing 1:50,000 scale maps. The minimum map unit (MMU) varies by land cover class and ranges from 0.22 to 5.12 acres.
In general, the mapping methodology used a hybrid, hierarchical classification of multi-temporal, multi-resolution imagery to develop modified Anderson Level II through Anderson Level IV land cover maps of the Kansas River Watershed and the State of Kansas. More specifically, multi-seasonal Landsat Thematic Mapper (TM) imagery from the 2004 and 2005 growing season was used to map the grassland subclasses (cool- and warm-season grasslands). while MODIS NDVI time-series imagery from the 2005 growing season was used to map cropland subclasses.
The land use/land cover classes in the Level IV map are coded hierarchically to allow aggregation of land use and land cover classes as needed by the end-user. For example, a user can aggregate the Level IV map classes to a Level III classification by ignoring or eliminating the last digit of each land use/land cover class. Likewise, a Level II and Level I map can be created from the Level IV map by eliminating the last two and three digits, respectively, from each Level IV land use/land cover class.
A formal accuracy assessment found the Level II, Level III, and Level IV maps to have overall accuracy levels of 86.3%, 82.0%, and 74.3%, respectively. User and Producer (per-class errors of commission and omission) accuracies vary by land cover class and users are encouraged to reference the reported accuracy levels in the final report and/or metadata when using the Kansas Land Cover Patterns map series.
