1 PRODUCT DESCRIPTION Sabie Environmental Consulting TITLE: Remote sensed land cover classifcation REQUIRED BY: Biological Science DepartmentPRODUCT # 34 NAME: Robert Sabie SUMMARY: This product will provide the biological science department a quantification of the different land coverages within the park boundaries. Multi-temporal Landsat TM data sets exist which allows the technicians the ability to measure land cover change over time, identify areas of vegetation stress, and in a broad scope identify the effects of climate change. The final output of this product will be a map of the different land coverages that includes a quantified summary of all the land coverages within the park boundary.
