Book Description
Analyzes how well the Natural Heritage Classification (NHC) and the Anderson Classification systems classify an area based on Landsat imagery and a modern (circa 2002) land cover map created by the Canandaigua Lake Watershed Council (CLWC). A geographic information system (GIS) is used to reclassify the Landsat imagery into land uses and land covers based on the two classification systems and to produce tables expressing the accuracy of each system as compared to the truth image.

Determination of Land Use from Satellite Imagery for Input to Hydrologic Models
Author: Robert P. Webb
Publisher:
ISBN:
Category : Aerial photography in hydrology
Languages : en
Pages : 28
Book Description
A land use/land cover identification methodology using LANDSAT imagery has been applied to six watersheds across the U.S. The land use information is stored in a grid cell data bank and is the basis for calibration of hydrologic parameters for watershed models. Flood frequency studies have been completed on four of the watersheds with land use derived from both satellite data and conventional low altitude aerial photography. This paper discusses our experience using the LANDSAT land use classification procedure and compares hydrologic results obtained from the alternative determinations of land use. (Author).

Determination of Land Use from LANDSAT Imagery: Applications to Hydrologic Modeling

Pages : 79
Book Description
An operational procedure for determining land use from LANDSAT imagery was applied to five watersheds: Crow Creek, Walnut Creek, Rowlett Creek, Pennypack Creek, and Castro Valley (University of California, Davis (USD) staff performing the work on the latter three watersheds). Based on this work the following conclusions can be made: At the grid cell level LANDSAT land use was in error approximately one-third of the time. By aggregating land use over the entire watershed, LANDSAT's average misclassification of land use reduces to 2-8% for the major land use categories. The commercial classification was less accurate at the grid cell level than the UCD procedure classification; errors at the watershed level were nearly the same for both. Evaluated in terms of the difference in discharge frequency curves derived using the same hydrologic model but different land use (LANDSAT and conventional), the LANDSAT derived land use found to be completely adequate. The number and type of land use categories derived from LANDSAT data were sufficient to be able to apply two standard hydrologic modeling techniques; Snyder's unit hydrograph and percent imperviousness and the SCS curve number method. The UCD procedure works. It is a complete, self-contained package of computer programs and manual operations that permit a user to identify land use from LANDSAT digital data without requiring the use of expensive interactive image processing equipment. LANDSAT land use can be directly incorporated into a grid cell data bank, thus providing and automated environment for applying the LANDSAT classification in routing hydrologic investigations.

Book Description
"The effective and defensible utilization of any thematic map requires that the user has a knowledge of the accuracy with which the map was made. The objective of this project was to determine the accuracy with which the land use and cover data mapped by GEONEX, Inc. for the Southwest Florida Water Management District reflects the actual occurrence of features on the earth's surface. The project goals were as follows: Determine the overall map accuracy -- Determine the per class map accuracies -- Determine if there are spatial variations in overall of per class accuracies -- Utilize statistically sound techniques for determining the above."--leaf [1]
