CIB (Controlled Image Base)
CIB (Controlled Image Base) file format is a format used in ArcGIS for storing and managing raster data, typically employed alongside geodatabases as part of raster datasets, mosaic datasets, or raster catalogs. It defines the storage method for pixels, such as the number of rows, columns, and bands, serving as a native format for internal data exchange and management within the ArcGIS ecosystem. For more general image processing, common formats such as JPEG, PNG, and BMP may be more suitable.

ESRI Spatial Analysis is the core spatial analysis toolkit within the ArcGIS platform, supporting advanced spatial modeling techniques such as terrain modeling, location analysis, pattern recognition, and change detection. The Geometry API provides geometric object processing capabilities, including point/line/polygon operations, spatial relationship analysis, and geometric calculations, with support for standard formats such as GeoJSON and WKT. Both are integrated into ArcGIS Pro and the Python API, require specific licenses (such as a Spatial Analyst license), and it is recommended to migrate from ArcGIS Desktop to ArcGIS Pro for use.

GeoVRML (Geographic Virtual Reality Modeling Language) is an extension of VRML (Virtual Reality Modeling Language) designed specifically for the 3D visualization of geospatial data. It uses standardized tags to describe terrain, coordinate systems, and geographic objects, enabling the sharing and interaction of 3D geographic scenes over the internet. It is commonly used for virtual simulation in fields such as Digital Earth and urban planning.
2025-11-05 14:03:13DRG (Digital Raster Graphic)
DRG (Digital Raster Graphic) is a raster data format created by scanning paper topographic maps at high resolution and adding georeferencing information. Primarily produced by the United States Geological Survey (USGS) through digitization of topographic maps, it preserves map information such as contour lines, roads, hydrography, and administrative boundaries as images. Since DRG contains geographic coordinate information, it can be overlaid with other geographic data in GIS and is widely used as base maps or reference maps.
2026-03-07 14:06:22DOQ (Digital Orthophoto Quadrangle)
DOQ (Digital Orthophoto Quadrangle) is orthorectified aerial photograph data created in the United States. Primarily provided by the United States Geological Survey (USGS), it corrects distortions caused by terrain relief and camera tilt in aerial photographs, allowing it to be used as image data with the same coordinate accuracy as maps. DOQs are typically created for areas corresponding to quarter sections of 1:24,000 scale topographic maps (Quadrangles) and are characterized by their ability to accurately represent features such as roads, rivers, buildings, and vegetation based on actual geographic coordinates. Therefore, they are widely used as foundational data in diverse GIS applications including map creation, urban planning, and land use analysis.
2026-03-07 14:36:313D Tiles (Cesium Standard)
3D Tiles (Cesium Standard), as an open standard, defines methods for streaming transmission and visualization of large-scale 3D geospatial data on the web. Proposed and open-sourced by the Cesium team, it has now become an OGC (Open Geospatial Consortium) Candidate Standard and is widely used in digital cities, smart campuses, geological exploration, and other fields. Its core design employs a Hierarchical Level of Detail (HLOD) structure, which uses spatial partitioning algorithms to divide 3D models into multi-resolution tiles. This supports dynamic data loading based on the view frustum range, effectively addressing issues in traditional 3D models such as excessive memory usage and rendering lag in browsers.
2025-11-24 14:49:58GraphHopper Directions API
GraphHopper Directions API is a route planning and navigation service based on a RESTful architecture, provided by GraphHopper GmbH. It leverages OpenStreetMap data to provide global map coverage and supports route calculation for multiple modes of transportation (such as driving, cycling, walking, public transit, etc.). It integrates functionalities like real-time traffic information, route optimization, geocoding, and isochrone analysis. Developers can quickly integrate it into applications using its Java or JavaScript clients. It is suitable for scenarios like logistics and distribution, traffic navigation, and geographic information systems, combining open-source flexibility with commercial-grade performance.
2025-12-29 14:00:14Esri GeoEvent Server
Esri GeoEvent Server is an enterprise-level software provided by Esri, designed for real-time processing, analysis, and dissemination of event-based geospatial data streams. It can connect to multiple real-time data sources, perform real-time analysis on event data through filters and processors, and deliver processed results to client applications, feature services, dashboards, or other destinations. This technology is commonly used in smart cities, traffic monitoring, and other scenarios requiring real-time responsiveness, helping users quickly adapt to dynamic changes.
2025-11-24 15:46:07BSB (Nautical Chart Raster Format)
BSB (Nautical Chart Raster Format) is a raster data format primarily used for storing and distributing Raster Navigational Charts (RNC). Originally developed for chart distribution, it has now become one of the standard distribution formats for official raster navigational charts issued by hydrographic offices in various countries. The BSB format adds georeferencing information to scanned paper chart image data, enabling accurate position display on navigation support software. It is characterized by its design specifically tailored for maritime navigation applications.
2026-03-07 14:20:53S57 (Standard for Electronic Navigational Charts)
S57 (Standard for Electronic Navigational Charts) is an international standard developed by the International Hydrographic Organization (IHO) for the exchange and display of electronic nautical chart data, primarily used in marine navigation systems. It standardizes the format, structure, and content of chart data, ensuring interoperability between electronic nautical chart systems from different manufacturers, providing ships with accurate and unified critical navigation information such as water depth, channel, and obstacles. In short, S57 is the "universal language" of electronic nautical charts, ensuring safe and efficient maritime navigation.
