USING OF VEGETATION INDICES FROM THAICHOTE SATETLLITE DATA FOR FOREST TYPES CLASSIFICATION EM DOI LUANG NATIONAL PARK, CHIANG RAI PROVINCE

摘要

The research aims to study the reflection of light derived from multispectral instrument on board THAICHOTE satellite. The relationship between forest types and vegetation index data in Doi-luang national park, Chiang rai province.Guidelines for application of vegetation index classification forest types, with the second method is to determine the extent of forest to create a range of conditions. And classificationdata monitoring by the supervised classification maximum likelihood model The vegetation indices utilized the equations is normalrized difference vegetation index (NDVI), ratio vegetation index (RVI), difference vegetation index (DVI), infrared percentage vegetation index (IPVI), transformed normalized difference vegetation index (TNDVI) and soil adjusted vegetation index (SAVI), using a satellite image of THAICHOTE between November 6, 2010 and on February 17, 2011.
