Introduction

In recent years, with the sustained and rapid development of the national economy, remote sensing technology plays an important role in the investigation of land and resources, especially in geology.

Remote sensing imagery is widely used in survey applications. Due to the lack of uniform technical requirements for the production of digital remote sensing image maps, Remote sensing image maps have large differences in image processing, image accuracy, surface decoration, and surface annotation. At the same time, remote sensing image maps the data structure and format are also inconsistent, which affect the versatility of remote sensing image maps. The development and implementation of this standard, the standard remote sensing the production of image maps, improving the ability of image map data sharing, and improving the application level of remote sensing technology will play an important role.

Remote sensing image map production specification (1.50000/1.250000)

1 Scope

3 Terms and definitions

The following terms and definitions apply to this document.

Remote sensing image map Based on remote sensing image elements, supplemented by appropriate geographic elements, it has a strict mathematical foundation and standardized surface decoration, in line with the map.

What is the accuracy required for the drawing.

Ground resolution

The physical resolution of remote sensing instrument design, also known as spatial resolution, is the size of the real area of remote sensing image pixels. When represented by pixels when the ground range is square, it is usually expressed by a side length of the cell.

Image resolution Refers to the number of points per unit length of the remote sensing image, expressed in points per inch (dpi), reflecting the dimensional accuracy of the input pixel.

Image registration Accurate superposition of spatial locations of the same-named points between satellite images acquired at different times or between different bands of images.
