All-in-One Lightweight GIS Platform

E01 file is a dedicated data archive file format used to store and transmit large-scale GIS data sets. It was developed by Esri to improve the performance and efficiency of GIS data. The E01 file uses a binary format and has a high compression rate, which can organize a large amount of geographic data in a single file. E01 files are usually used to store raster data, vector data, topological data, attribute data, etc. It also supports data indexing and querying to speed up data access and analysis.

Parasolid is a core technology of Siemens for accurate geometric modeling that is widely used in the fields of 3D computer-aided design (CAD), computer-aided engineering (CAE) and computer-aided manufacturing (CAM). It also plays an important role in GIS (Geographic Information System) processing of complex spatial data scenes involving high-precision 3D terrain, building models, etc. It stores and exchanges accurate geometric information of 3D models in a neutral file format, providing strong support for data interaction between different software.

Autodesk Maya is a professional-grade 3D computer graphics software developed and provided by Autodesk. It is widely used in industries such as film, animation, games, commercials, and architectural visualization, and is suitable for scenes that require high-level 3D modeling, animation, rendering, and simulation.

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.

**PRJ **(Projection) file is one of the common file formats in Geographic Information System (GIS), which is used to store spatial reference information and coordinate system definition. PRJ is the abbreviation of Projection, which is usually used with other geographic data files (such as vector data, raster data, etc.) to determine the geographic location and coordinate system of the data.

MapGIS is a domestic geographic information system (GIS) platform developed by China’s Zondy Cyber Group. The platform was born in the 1980s and has become one of the most widely used GIS software in China. MapGIS provides a variety of product lines such as desktop GIS, server GIS, Web GIS, and cloud GIS, which can realize the collection, management, analysis, visualization and sharing of spatial data.

GeoPackage (GPKG) is an open standard geospatial data storage format launched by OGC (Open Geospatial Consortium). It is based on SQLite database files and can efficiently store and manage vector data, raster data, and other spatial related information. GPKG files are designed to solve the problems of fragmentation and poor compatibility of traditional GIS file formats, and support offline data storage and cross-platform data sharing through a unified format. Compared with traditional GIS files (such as Shapefile or GeoTIFF), GPKG files have greater flexibility and scalability and are considered to be an ideal choice for modern geographic information applications.

PDS (Plant Design System) Design Review is a solution for performing design reviews using 3D models, primarily in plant design and large facility construction projects. It visually verifies design components such as piping, equipment, and structures through interactive 3D visualization, enabling interference checks and early detection of design errors.

BIL (Band Interleaved by Line) is a geospatial data format commonly used to store remote sensing images and geographic information system (GIS) data. BIL is a multi-band image storage method with interleaved lines. Its core feature is to store multi-band image data alternately in the file in line order. That is, each line of data contains the pixel values of all bands, and the storage order is: the first line of band 1, the first line of band 2, …, the first line of band n, and then the second line of all bands, and so on.

MXT (Map Exchange Template) file is a file format used in Esri ArcGIS software to store map display and configuration information, including layers, symbol styles, label settings, etc. It saves the appearance and layout of the map and can contain multiple layers and related map elements.
