The MRLC viewer provides a dynamic platform for data visualization of the NLCD product suite and supports user defined data subsetting and downloads.
MRLC NLCD Mapping Tool
The NLCD mapping tool is a custom ERDAS Imagine add-on module with 5 components. The NLCD Sampling Tool is designed to sample independent and dependent variables to develop input for Cubist Regression Tree Classifier models (used for continuous variable modeling of canopy, imperviousness, and shrubland components), or the See 5 Decision Tree Classifier models (for thematic land cover modeling). Additional tools included are the NLCD Smart Eliminate Tool that provides an interface for weighting classes while establishing a minimum mapping unit, an accuracy assessment modeler and percent area modeler. These tools provide the foundation for NLCD modeling and production and are available for download at no cost to the user. Current versions supported are Erdas 8.7 through 2011 and Erdas 2016 through 2018.
