What is GIS in GIS workgroup?

GIS (Geographic Information System) is the abbreviation of Geographic Information System.
Overview of GIS basic concepts
1. Geographic Information System (GIS): a new discipline integrating computer science, informatics, geography, and other sciences, with the support of computer software and hardware, it uses the theory of system engineering and information science to scientifically manage and comprehensively analyze geographical data with spatial connotations, to provide spatial information systems for planning, management, decision-making, and research. GIS has the following subsystems: Data Input subsystem, data storage and retrieval subsystem, data operation and analysis subsystem, and report subsystem.
Information System
Non-spatial
Managing Non-geographic GIS of Information Systems
CAD/CAM other GIS LIS
The social economy and census are based on non-land plots and

2. Compare the similarities and differences between GIS, CAD, and CAC.
CAD: a computer-aided design. The system for generating, editing, and displaying rule images is independent of external description data.
CAC-computer-aided plotting is a specialized software suitable for map plotting and lacks spatial analysis capabilities.
GIS is a geographic information system that combines rule graphics and map graphics with strong spatial analysis capabilities.
3. layer: a topic that divides space information according to its geometric features and attributes.
4. Geographic Data Collection-on-site investigation and sampling; traditional measurement methods, such as triangle measurement and three-way measurement; GPS; Modern Remote Sensing Technology; Biological telemetry; digital photography technology; Census.
5. Information example-a traditional plotting method called an information example, That is, assuming that a map itself is a final product, the space information is exchanged through the selection of symbols and classification restrictions. This example is a traditional perspective method. Due to its primitive limitations, map users cannot easily obtain pre-classified data. That is to say, the user can only process the final product, but cannot reorganize the data into a more effective form to adapt to changes in the environment or needs.
6. analysis example (overall example)-stores the attribute data of the original data and displays, restructured, and classifies the data as needed. The overall example is a real overall approach for Cartography and geography.
7. Grid-the grid structure is the simplest and most direct spatial data structure. It refers to dividing the earth's surface into a grid array of uniform and closely adjacent sizes, each grid is defined by rows and columns as a pixel or pixel, and contains a code to indicate the attribute type or value of the pixel, or only includes a pointer to its attribute record. Therefore, the raster structure uses a regular array to represent the data organization of spatial objects or phenomena distribution. Each data in the Organization represents the objects or non-geometric characteristics of phenomena. Feature: The property is obvious and the positioning is implicit, that is, the data directly records the property itself, and the position is converted to the corresponding coordinates based on the row and column numbers, that is, positioning is obtained based on the location of the data in the dataset. In the raster structure, the point is represented by a grid unit, and the linear object is represented by a group of adjacent grid units along the line, each raster unit can only have two adjacent units online. A plane or area is represented by a set of adjacent raster units with region attributes. Each raster unit can have more than two adjacent units in the same region.
8. Vector: it assumes that the geographical space is continuous. By recording coordinates, it can accurately represent geographical entities such as points, lines, and polygon. The coordinate space is set to continuous, allows precise definition of any position, length, and area. For a point object, the vector structure only records its coordinates and attribute codes in a specific coordinate system. For a line object, it is represented by a series of coordinate pairs; A polygon is a space area with a completely closed boundary. It is represented by a series of coordinate pairs.

9. The word "Topology" comes from Greek, and its original intention is "shape research ". Topology is a branch of the geometry. It studies the geometric properties that can be kept unchanged under the topological transformation-topological properties (topological properties: the endpoint of a point in a arc segment, A point is located on the boundary of an area. Non-topological attributes include the distance between two points, the length of the arc segment, and the perimeter and area of the area ). This structure should include: Unique identification, polygon identification, outsourcing polygon pointer, adjacent polygon pointer, boundary link, range (maximum and minimum x and y coordinate values ).
