Introduction
GB/T 35638—2017 In-depth Interpretation of Geographic Information Location Service Terminology
Background and Significance of Standard Formulation
Geographic Information Location Service (LBS) is an important part of modern information technology and is widely used in mobile Internet, navigation, emergency rescue and other fields. With the rapid development of global navigation satellite systems and the maturity of indoor positioning technology, the demand for LBS is growing.
GB/T 35638—2017 "Geographic Information Location Service Terminology" is a standard managed and formulated by the National Geographic Information Standardization Technical Committee under the leadership of the National Administration of Surveying, Mapping and Geoinformation. This standard aims to unify the location service terminology in the field of geographic information and provide a standardized reference for research, development and application in related fields.
Core Terminology Analysis
| Terms | Definition | Application Scenarios | Related Technologies |
|---|---|---|---|
| Geographic Information | Information about phenomena directly or indirectly related to locations on the earth's surface. | Electronic Maps, Navigation Systems | Spatial Database Management |
| Point of Interest (POI) | A specific spatial object with attributes and locations that users are interested in. | Mobile Application, Location Query Service | POI Data Collection and Management |
| Positioning System | A system used to determine the position of a spatial object. | Satellite Navigation, Indoor Positioning | Multimodal Positioning Technology |
Evolution and Comparative Analysis of Positioning Technology
Satellite Positioning is one of the most commonly used positioning technologies. Its core principle is to calculate the user's position by receiving Global Navigation Satellite System (GNSS) signals, such as GPS, Beidou, GLONASS, etc. This technology has the characteristics of wide coverage and high accuracy.
Indoor Positioning is a technology that has developed rapidly in recent years, mainly solving the problem of weak satellite signals in indoor environments. Common indoor positioning technologies include Wi-Fi positioning, Bluetooth positioning and inertial navigation.
Comparison of standard frameworks and implementation suggestions
GB/T 35638-2017 is consistent with international standards (such as ISO 19148) in terms of terminology definitions, while combining China's geographical characteristics and technological development level. The following is a comparison and analysis of the standard framework:
- Scope of application: This standard applies to management, research, development and application activities in the field of geographic information.
- Core terms: Including key concepts such as POI, positioning system, navigation service, etc.
- Technical requirements: Emphasize multimodal positioning technology and seamless indoor and outdoor connection capabilities.
Implementation Suggestions
To ensure the effective implementation of the standard, it is recommended to start from the following aspects:
- Strengthen the promotion of standards: Through training and case sharing, improve the industry's understanding and application capabilities of the standard.
- Promote technological innovation: Encourage the research and development and application of multi-modal positioning technology to improve the accuracy and reliability of location services.
- Improve the ecosystem: Build a unified location service platform to promote cooperation and coordinated development of upstream and downstream of the industry chain.
