Abstract

The invention discloses a calculation method of water area remote sensing information of Landsat satellite sensors. The calculation method comprises the following steps: step 100, receiving Landsat satellite remote sensing data; step 101, performing data preprocessing; and step 102, selecting data of the first, second, third, fourth, fifth and seventh wave bands of Landsat satellite Thematic Mapper (TM) sensor and Enhanced Thematic Mapper (ETM) sensor or data of the fourth, fifth, sixth and seventh wave bands of Landsat satellite Multi-Spectral Scanner (MSS) sensor. The calculation method of the water area remote sensing information of the Landsat satellite sensor is a method for obtaining water area information by judging remote sensing data through multiple conditions, so that extractionprecision of the water area information is improved. The calculation method of the water area information in the invention is more suitable for calculating the water area information by utilizing theLandsat satellite sensors, and is faster, automatic and less manual compared with actual measurement. Furthermore, the method has long time series, so that past precious historical data of the earthare kept, which is extremely important for calculating the water area information.

Description

technical field [0001] The invention relates to the technical field of remote sensing, in particular to a water area information calculation method based on Landsat satellite sensor remote sensing data. Background technique [0002] Water is an indispensable material condition for human survival. With rapid urbanization, the number and shape of water continue to change in space, and the protection of water is severely tested. Remote sensing technology has the advantages of macroscopic, dynamic, synchronous, fast, etc., and it can obtain the temporal and spatial distribution characteristics of a wide range of waters. Generally, the waters are densely covered and the river network is vertical and horizontal. To obtain practical water information, the traditional on-site survey method is often time-consuming and labor-intensive due to the high cost of monitoring, and is affected by the environment, so it is impossible to obtain data dynamically and quickly. Therefore, remote s...
