Foreword

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

Introduction

With the extensive acquisition and deep application of optical remote sensing satellite image resources, the sharing and service of image information has become a way to enhance remote sensing images.

The important guarantee of the application level. Image product metadata is data about image data. It is used to solve the problem of finding images and understanding images.

Degrees, accessing images, converting images, and using images provide the necessary information.

Optical Remote Sensing Mapping Satellite Image Product Metadata is the basic arity needed to describe various scale optical remote sensing satellite imagery products.

According to the collection of elements. In order to coordinate the implementation of " 1.250001.50000 Optical Remote Sensing Mapping Satellite Image Product", it is also used to make remote sensing The establishment and maintenance of mapping satellite image metadata can be implemented in accordance with uniform standards in order to achieve better image resource sharing and information services.

Socialization, specifically formulated this standard.

This standard refers to GB/T 19710-2005 "Geographic Information Metadata" and the international standardization of geographic information during the formulation process.

4 Basic requirements

4.1 General requirements

This standard defines the metadata needed to describe the imaging products at all levels of the optical remote sensing satellites. Each remote sensing image product should provide The appropriate metadata. Metadata consists of one or more metadata subsets (UML packets) that contain one or more metadata entities (UMIs)

Classes), they can be specialized (subclasses) or generalized (superclasses). Metadata entities contain elements that identify each metadata unit (UML Class attribute). An entity can be related to one or more other entities. Entities can be aggregated or repeated as needed to satisfy. a) the requirements of this standard Required requirements; b) User's other requirements.
