Introduction

As an important basic strategic resource for national economic and social development, geographic information is more and more widely used in national, social and public affairs all aspects of life.

Its core is to solve the problem of user's knowledge and acquisition According to the channel problem, the data arrive from the provider to the user.

Traditional data distribution is mainly done manually, and after the provider prepares the data product, it disseminates data messages through various information channels Interest, the user access to data information to the designated location to purchase or order data products.

With the improvement of the application of science and technology, the demand for geographic information in various sectors of the national economy is increasing. As for the traditional data distributor Type proposed a challenge. With the development of information technology, especially the extensive application of network technology, the emergence of network-based geographic information data distribution the way.

Network-based data distribution is mainly based on online services providers to prepare data products, the establishment of the corresponding network services, to provide users with online data discovery, preview, download, custom features, for custom products, online or offline and other access methods available.

In the process of data distribution, providers should follow the relevant safety requirements of the information security standards of the state and relevant departments.

In response to rapidly growing data needs, there is a need to guide and regulate web-based data distribution. To this end, we make this guidance document provides guidance on technical requirements for web-based data distribution in the field of geographic information.
