Vector data is data that uses x and y coordinates to represent the location and shape of map graphics or geographic entities in rectangular coordinates. Vector data generally records the coordinates to accurately represent the spatial location of geographic entities as much as possible.

**GeoTIFF **(Geographic Tagged Image File Format) is a commonly used geographic information image file format that combines image data and geographic information data and can be used to store and transmit image data with geographic location references. The GeoTIFF format supports embedding geographic information such as geographic coordinates, projection information, and ellipsoid parameters into image files, so that the image can correspond to the geographic spatial coordinate system.

Raster data is a commonly used data format in geographic information systems (GIS). Its essence is a two-dimensional or three-dimensional data grid composed of a collection of pixels (grid cells). Each pixel (or cell) stores specific geographic information, such as terrain elevation, land use type, temperature or precipitation, expressed in the form of a numerical value. In the field of GIS, satellite images, aerial photos, digital elevation models (DEMs), etc. are usually stored and used in the form of raster data.

ESRI (Environmental Systems Research Institute) is a leading global provider of geographic information system (GIS) software, headquartered in California, USA. Founded in 1969, the company focuses on providing geospatial data collection, management, analysis and visualization solutions. ESRI’s products are widely used in urban planning, disaster management, environmental monitoring, transportation, agriculture, disaster prevention and other fields, and are widely adopted by government agencies, enterprises and research institutions around the world.

SuperMap is developed by Beijing SuperMap Software Co., Ltd. It combines spatial data processing, geographic information visualization and powerful spatial analysis functions. SuperMap mainly consists of four parts: desktop tools (SuperMap Desktop), secondary development components (SuperMap Objects), network development tools (SuperMapIS .NET) and embedded development tools (eSuperMap).

AutoCAD is a widely used software in the field of computer-aided design (CAD), developed by Autodesk. It provides a wealth of design and drawing tools that can be used to create and edit 2D and 3D graphics.

ArcGIS is a geographic information system (GIS) software platform developed by ESRI (Environmental Systems Research Institute). It provides a wealth of tools and functions for capturing, managing, analyzing, and displaying geographic data. ArcGIS has a variety of applications, including map making, spatial analysis, geolocation, resource management, environmental planning, and other fields.

GeoDatabase is a geographic database used to store and manage geospatial data. It is a database format developed by Esri and is widely used in the field of GIS (Geographic Information System). GeoDatabase takes spatial data as its core and can store various geographic features and attribute information, such as maps, terrain, land use, road networks, water areas, etc. It supports a variety of data types, including points, lines, surfaces, rasters, topology, etc., and can accurately represent and process the location, shape and attributes of geographic objects.

SDX (Spatial Data Exchange) is a common file format used to share and transfer spatial data between different GIS software. It can contain vector data and raster data, as well as attribute information related to them. They can store the geometry, topological relationships, attribute data, and spatial reference information of geographic features. By using SDX files, users can import, export, and share geographic data in different GIS software to achieve data interoperability and scalability.

WL files usually stand for Workspace Files, which play an important role in saving and managing geographic data and related settings in MapGIS. They help users maintain the consistency of their work status and provide convenient data access and analysis functions.
