Geographic information science is a discipline and specialty that studies the spatial distribution of the earth's surface, the correlation between geographical phenomena and geographical processes, and the acquisition, analysis and application of geographic data by means of information technology.

1. Subject introduction

Geographic information science is a comprehensive discipline, which combines the knowledge and methods of geography, surveying, computer science, remote sensing science and other disciplines. It mainly focuses on the acquisition, management, analysis and application of geographic information and geospatial data on the earth's surface, as well as the simulation and prediction of geographical phenomena.

2. Research content

The research contents of geographic information science include geographic information system (GIS), remote sensing technology, global positioning system (GPS), geographic database, cartography, geospatial data mining and so on. Through the observation and measurement of geographical phenomena and processes, with the help of various information technology means, geographical data are collected, sorted, processed and analyzed to reveal the interrelations and laws between geographical things.

3. Subject application

Geographic information science is widely used in various fields. In urban planning and land use, GIS can be used for spatial analysis and decision support; In environmental protection and natural resources management, remote sensing technology can be used for monitoring and evaluation; In the fields of transportation and logistics, GPS can be used for path planning and vehicle scheduling. In addition, geographic information science is also applied to agriculture, meteorology, geology, energy and other fields.
