| Introduction
In late 1999,
the U. S. Department of Agriculture National Agricultural
Statistics Service (NASS), the Illinois Department
of Agriculture (IDA), and the Illinois Department
of Natural Resources (IDNR) began a cooperative, interagency
initiative to produce statewide land cover information
on a recurring basis. The Illinois Interagency Landscape
Classification Project (IILCP) completed Cycle 1 of
this initiative in the summer of 2002, resulting in
the Land Cover of Illinois 1999-2000 inventory and
associated database.
Data
Products
The Land Cover of Illinois 1999-2000 database includes
four distinct, but closely interrelated products.
- Land
Cover of Illinois 1999-2000 Classification
- Statewide
Landsat 7 ETM+ Panchromatic Image Mosaic
- TM
Path/Row Pseudocolor Spectral Class Maps
- Land
Cover of Illinois 1999-2000 On-Line Statistical
Summary
Land
Cover of Illinois 1999-2000 Classification
This is the primary product of the IILCP
initiative and is the result of integrating the directed
supervised classification of agricultural lands and
the unsupervised classification and spectral class
labeling of non-agricultural lands. The primary source
information for the computer classification is Landsat
5 TM and Landsat 7 ETM+ satellite imagery acquired
for three dates (triplicates) during the spring, summer,
and fall seasons of 1999 and 2000. (see
1999-2000 TM Coverage Map).
