Method for making remote sensing shadowgraph of positive landform

Abstract

The positive landform remote sensing image preparation method concerns that according to traditional remote sensing mapping method, obtain current azimuth angle, incident angle of sun by sensing data; correct forming positive landform factor by radiation and shadow; form positive landform remote sensing image fit to people vision habit by data fusion. The characteristic is that the formation of image just lies on original satellite data, needs no DEM, and can realize multiple dimension scales formed image fit to application and research of Quaternary Period landform, land detection, geologic hazard, prospecting in geology, hydraulic engineering research and military affairs, etc.

Description

Technical field: [0001] The invention relates to fine correction of remote sensing images, registration of images, information enhancement, data fusion and image finishing, and belongs to the field of remote sensing image processing and production. Background technique: [0002] With the implementation and development of a series of geographic information systems such as digital city, digital land, and digital earth, remote sensing images have received more and more attention because of their rich information and intuitive expression, and have become more and more popular in different fields, used by people of different classes. However, traditional remote sensing image maps often cause illusions in visual interpretation, especially people without remote sensing background knowledge often regard rivers as mountain ridges and mountain ridges as rivers, causing great trouble to people when they are applied. Although the 3D remote sensing image with the digital elevation model...

However, traditional remote sensing image maps often cause illusions in visual interpretation, especially people without remote sensing background knowledge often regard rivers as mountain ridges and mountain ridges as rivers, which cause great trouble to people when they are applied

Although the 3D remote sensing image with the digital elevation model (DEM) as the elevation has great advantages, it is very inconvenient to describe the 2D information.
