All-in-One Lightweight GIS Platform

VDC (Virtual Design and Construction) is a technology and methodology used in the fields of architecture, engineering and construction (AEC). It combines building information modeling (BIM), 3D visualization and other digital tools to perform virtual simulation and management during the design, planning and construction stages of a project. By digitizing the construction process of the entire project, VDC can optimize collaboration, improve efficiency and reduce risks, thereby increasing the success rate and profitability of the project.

TAB file is a file format used to describe geographic spatial data. It is usually a logical “data table”, but it not only contains tabular data, but also links to other files to provide spatial reference and geometric data. It is the main format for MapInfo software to read and write spatial data. It is suitable for storing vector data types such as points, lines, polygons, and can support topological structures and coordinate information. It is widely used in the GIS industry for its good structure and powerful functions, and can store spatial data and related attribute data.

DAT files are a general-purpose binary data file format that is widely used to store different types of data, such as program configuration information, images, audio, video, spreadsheets, database files, etc. They are usually created and read by applications to store application-specific information, and the specific content and format depend on the application that created it.

In GIS (Geographic Information System), ID files usually refer to identification files, which are files used to identify data sets. They usually contain metadata information such as the name, version, author, format, creation date, scope, and summary of the data set to help users understand and manage the data set. The format of the ID file can be a text file, XML file, or other structured format. In GIS, the metadata information of the data is very important, which can help users better understand the data set, evaluate data quality, and select appropriate data and analysis methods. Therefore, the ID file is also very important.

MAP (Map) is a visualization tool based on geographic location information, which displays geographic location and geographic data in a graphical way. In GIS, MAP usually refers to a map file, which contains the basic data, style and metadata of the map. Map files can be created by GIS software or provided by third-party data providers. In GIS, map files can be used to better manage and organize map data and make it easier to share and integrate with other GIS software.

IND (Interchange of Navigational Data) is a data exchange format used in the field of navigation and is also a data format in GIS. IND files usually contain nautical charts and navigation-related data, such as routes, ship positions, port information, navigation marks, etc.

OSM (Open Street Map) is an open source map dataset created and maintained by a volunteer community. Unlike traditional map data, OSM data is collected by volunteers using various data sources such as GPS devices, aerial images, topographic maps, and public satellite images. Users can use, edit, and distribute this data for free. OSM has global coverage and provides rich geographic data, including streets, buildings, rivers, lakes, mountains, public facilities, and more. At the same time, OSM also provides APIs and various tools to integrate this data into various applications.

GPF-DIME is a file format used to manage and store remote sensing image data and other geospatial data. It is mainly used for the storage, processing and transmission of remote sensing images. By providing a flexible and efficient data structure, this format allows users to use it to store and process images in different environments, especially when processing large-scale, high-resolution image data.

In GIS, a Coverage file is a data type used to represent a continuous area, usually composed of multiple grid cells spliced together. Each cell can contain one or more attributes, such as height, temperature, or land use type.

IMG file is an image data file format developed by ERDAS IMAGINE software, designed for remote sensing image and geospatial data processing. As a flexible and widely supported raster data format, IMG is widely used in remote sensing, geographic information system (GIS), land cover analysis and other fields.
