GB/T 40527-2021Digital space photogrammetry—Map surveying specification (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

Introduction

In recent years, with the continuous development of aerospace technology, remote sensing satellite image data has the advantages of fast acquisition, low cost, and no regional restrictions.

Gradually become an important means to obtain geospatial information. At present, optical remote sensing satellite images, especially high-resolution images, have become the basic ground.

The main data source for the construction of scientific information resources and other remote sensing applications.

In order to adapt to the current scientific and technological development status and actual technical requirements of information acquisition based on satellite images, it is necessary to establish a complete aerospace The photogrammetric standard system fills the gap in the digital aerospace photogrammetric standard. As an important part of digital aerospace photogrammetry For important links, this standard specifies related work content, technical procedures and technical requirements. The standards used in conjunction with this standard are "Digital Aerospace Photogrammetry Control Survey Specification, "Digital Aerospace Photogrammetry Aerial Triangulation Specification."

1 Scope
