This data is typically stored in a format that can be easily read and interpreted by GPS systems, ensuring seamless navigation and visual representation of our surroundings.
The main GPS map data formats include:
| Format | Description |
|---|---|
| GPX (GPS Exchange Format) | Open-standard format for storing GPS data, including location information, tracks, routes, and waypoints. |
| KML (Keyhole Markup Language) | Markup language used to store geographical data in a XML-based format, commonly used in Google Earth and other mapping applications. |
| OSM (OpenStreetMap) Format | Open-source project that provides a collaborative database of geographical features, including roads, buildings, and public transportation information. The data is stored in a binary format called PBF (Protocol Buffer Binary). |
| GeoJSON (Geographic JSON) | Widely-supported format for storing spatial data in JSON (JavaScript Object Notation) format, commonly used in web mapping applications, mobile apps, and software platforms that require flexible and scalable data representation. |
The main GPS map data standards include:
| Standard | Description |
|---|---|
| ISO 19107 (Geography – Metadata) | International standard for metadata management in geography, which provides a framework for describing and managing spatial data. |
| ISO 19110 (Geography – Methodology for feature types) | Specifies a methodology for defining feature types, such as points, lines, and polygons, that are used to represent geographical features on maps. |
| OGC (Open Geospatial Consortium) Standards | International organization that develops standards for geospatial data access and manipulation, including web services like WFS (Web Feature Service) and WCS (Web Coverage Service). |
