All-in-One Lightweight GIS Platform

RVT files are the native file format used by Revit, a BIM (Building Information Modeling) software developed by Autodesk. The format is designed to comprehensively manage and share information on architectural, structural, MEP (mechanical, electrical, plumbing) engineering projects, and store all data in the building life cycle, including 3D models, parametric data, drawings, material information, etc. RVT files are saved in a binary format and are widely used for design change management, collaboration, and visualization. It is highly compatible with Autodesk products and has become the standard BIM file format for the construction industry.

DWG (Drawing) files are a standard format for CAD (Computer-Aided Design) data developed by Autodesk. This format is widely used in architectural design, engineering, manufacturing and other fields, and is compatible with Autodesk’s AutoCAD and many other CAD software. DWG files contain 2D graphic data, 3D model data, layer information, dimensions, annotations, block information, etc., which can efficiently store and manage accurate design data. Since DWG is stored in binary format, the file size is small and the processing speed is fast, which is one of its main features.

SDE (Spatial Database Engine) is a software component used to manage and store geospatial data. SDE is a technology developed by Esri that is used to interact with geographic database systems and provide efficient management, query, and editing of spatial data.

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.
