:: About the Land Image Analyst Project

Land Image Analyst was developed by GDA Corp for the USDA Forest Service Chesapeake Bay Program as a land cover recognition tool to aid communities in developing land cover analysis and change detection. It has many applications, such as mapping tree canopy, identifying impervious surfaces, identifying stream buffers, and more.

The Green Infrastructure Center is supporting the Chesapeake Bay Program to promote and support this tool and provide guidance to development, as user feedback and support needs are identified. As part of the project, the GIC will provide regular reports to the developers based on both our own experience and those gathered by engaging users in training and support.

: Installation

Quick Start Guide

This guide will present the Graphic User Interface and available tools. It will also demonstrate the most commonly used classifier tools.
At the end of the project, a user should be able to accomplish two key tasks:
1) Creating a tree canopy map.
2) Creating a landcover map.

See the LIA Quick Start Guide.
