What are the basics that should be learned in the beginner learning stage of GIS?

Introduction to GIS, Principles of GIS, Application and Design of GIS, Basic Algorithms of GIS; Fundamentals of Geology, Introduction to Geomorphology; Economics, Humanities, Physical Geography; cartography, surveying, photography and digital surveying; GPS Far Principles and Introduction, Digital Elevation Models, Fuzzy Mathematics,

GIS = = Geographic Information System.

In the simplest terms, GIS is a global spatial analysis technology based on surveying and mapping, with a database as a data source for data storage and use, and computer programming as a platform. This is the essence and core of GIS. GIS stands for Geographic Information System, after 40 years of development, it has gradually become a fairly mature technology and has been widely used.

Especially in recent years, GIS has played an increasingly important role in GPS and path optimization with its powerful geographic information spatial analysis function. GIS is a technical system based on geospatial database, with the support of computer software and hardware, using the theory of system engineering and Pisanzhi information science, scientific management and comprehensive analysis of geographic data with spatial connotation, so as to provide information required for management and decision-making. To put it simply, a geographic information system (GIS) is a technical system that comprehensively processes and analyzes geospatial data.

Software mainly includes the following categories: operating system software, database management software, system development software, GIS software, and so on. GIS commonly used software AutoCADMAP3D, ArcGIS (including ArcGIS, Mapobjects, Arcims, ArcSDE, ArcEngine, ArcServer, etc.), MapInfo, MapGIS (MapGISK9 basic platform, data center integration and development platform, etc., the software series with the largest market share in China), SuperMap, etc.

1. Geoscience: General Geology, Physical Geography, Human Geography, Economic Geography, Introduction to Resource Science, Introduction to Environmental Science, Econometric Geography, etc.

2. Planning; Principles of urban planning, etc.;

3. Computer Science; Database, Programming, Secondary Development, C++, C Various.

Fourth, the overall planning; It is very helpful for organizing databases and managing data;

5. Remote sensing, etc.; RS, GPS and other professional disciplines for processing and analyzing geographic data;

6. Mathematics, physics and other science knowledge; Digital image processing, such as Fourier transforms, requires a lot of mathematics; Surveying and other things use a lot of knowledge of physical celestial motion;

That's all I can think of for the time being, but there are many, many more involved.

ArcGIS is more popular now, but it is more difficult than supermap.

If you want to engage in GIS applications, then you still use ArcGIS Desktop, which has mapping, map browsing, query, analysis, geoprocessing, etc., ArcGIS has a wealth of help and example documents, but most of them are in English, and the effect will be better if it is Chinese. In addition, GIS applications require professional knowledge in related industries (such as land, planning, environment, disasters, water conservancy, forestry, agriculture, digital cities, etc.), and you need to have an in-depth understanding of learning in some aspects in order to better prepare yourself for the workplace.

If you want to engage in GIS development, then it is best to learn a development language, and now the most development in GIS is to engage in secondary development, with a low threshold, and you are familiar with it. .NET's C is better because a lot of companies use C for their stuff. It is recommended that you still use ArcGIS to learn AO development, and if you are interested in WebGIS, you can learn Arcims or ArcGIS Server
