Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" drafted.
Introduction
Vegetation coverage reflects the lush degree of vegetation growth, and as one of the important biophysical parameters to describe the vegetation coverage on the surface, It is widely used in vegetation change detection, ecological environment assessment, soil and water conservation monitoring, climate change research and other fields.
It is of great significance to understand the laws of the ecological environment, to grasp the changes of the ecological environment and to analyze its development trend.
This document summarizes the concept, content, specifications, quality and other common information of vegetation coverage products produced by using satellite remote sensing images, and regulates their description, forming a product specification for vegetation coverage of satellite remote sensing images, as a common standard for the production and application of this product in related industries, it will be beneficial to planting Standardized production and efficient application of covered products. Product Specification for Vegetation Coverage of Satellite Remote Sensing Imagery
1 Scope
