All-in-One Lightweight GIS Platform

ASCAT (Advanced Scatterometer) is a active microwave radar instrument carried aboard the MetOp series of polar-orbiting satellites operated by EUMETSAT . As a real aperture radar scatterometer, ASCAT transmits C-band (5.255 GHz) microwave pulses and measures the backscatter from the Earth's surface to derive key geophysical parameters . The primary operational application is ocean surface wind vector retrieval, providing measurements of wind speed and direction over global oceans . Additionally, ASCAT data is used for soil moisture monitoring over land surfaces and sea ice detection . The instrument features two independent swaths of backscatter measurements, enabling wide spatial coverage and frequent revisit times.

The XYZ format is one of the most fundamental and widely used point data formats for describing three‑dimensional positional information using X, Y, Z coordinate values. It is typically stored as a text (ASCII) file, with each line representing a single point containing planar coordinates (X, Y) and a height or depth value (Z). Thanks to its simple structure, the XYZ format is utilized across a broad range of fields, including topographic surveying, point‑cloud processing, 3D modeling, GIS, CAD, and remote sensing.

TomTom Maps SDK / Web API is a toolkit integrated into web and mobile applications to build location-based service experiences. It provides map display, route planning, style customization, and data analysis capabilities, supporting multi-platform usage. The SDK allows developers to display multiple entity locations simultaneously on maps via API calls and leverages millions of data points collected by TomTom for efficient development. Compatible with both web-based and native mobile application platforms, it is suitable for various scenarios such as automotive navigation, public sector decision-making, autonomous driving, and logistics management.

CityGML, an international standard for the exchange of 3D city model data developed by the Open Geospatial Consortium (OGC), uses XML encoding to uniformly describe the geometric, topological, semantic, and appearance attributes of urban elements.

LVB is a proprietary geospatial data format developed by Beijing SuperMap Software Company, primarily used for storing and managing vector map data. Optimized for the SuperMap GIS platform, it supports efficient spatial data compression and fast retrieval, making it a popular choice for professional geographic information system applications in areas such as land planning and smart cities. It boasts strong compatibility and seamless integration with the SuperMap suite of software.

Pelias/geocode.earth API is an open-source geocoding service that provides bidirectional conversion between addresses and coordinates. It supports forward geocoding (finding location coordinates from an address) and reverse geocoding (retrieving specific location information from coordinates), and includes structured geocoding capabilities to handle segmented data (such as house numbers, streets, etc.). The API also offers autocomplete functionality, providing real-time suggestions for location names and returning detailed information including names, addresses, and coordinates. Its typical application scenarios include providing precise address search for mapping services, enabling real-time location navigation for mobile applications, and converting address data into geographic coordinates for spatial analysis.

GeoJSONB is a binary format used in PostgreSQL databases for storing GeoJSON data. It enables the database to handle geospatial data in a more compact and efficient manner. This format is supported by the PostGIS extension for PostgreSQL, which is a specialized geospatial database extension designed to enhance PostgreSQL's capabilities in managing location-based information.

The Planet Labs API is an API provided by the US-based company Planet Labs for delivering Earth observation satellite data. It is characterized by its ability to programmatically search, retrieve, and analyze satellite imagery captured by a large number of small Earth observation satellites (known as the "Dove" constellation), offering high-frequency and high-temporal-resolution data. A key strength lies in its "daily revisit" capability, enabling near-real-time monitoring of surface changes—a significant departure from traditional satellite data services.

GeoPDF embeds geographic spatial information (such as latitude and longitude coordinates and coordinate reference systems) in standard PDF files, enabling ordinary PDF readers (such as Adobe Reader) to support geographic location viewing, map navigation, and basic geographic analysis functions, combining the portability of PDF with the data analysis capabilities of GIS.

COLLADA / DAE is an open standard 3D data format designed for the exchange of 3D models and digital assets. Managed by the Khronos Group, it is XML-based and can describe 3D geometry, materials, textures, animations, scene structures, and more. It is widely used as a "neutral exchange format" enabling data interoperability between different software applications in game engines, 3D CG production tools, BIM, and the 3D GIS field.
