In GIS (Geographic Information System) applications, efficiently managing and publishing geographic data is a key step. This article will detail the concept of GeoJSON files, the steps to add GeoJSON data in GISBox, and how to publish vector services, helping users quickly master the methods for sharing and applying geographic data.
- What is a GeoJSON File? GeoJSON is a geospatial data interchange format based on JSON (JavaScript Object Notation), used to represent simple geographic features (such as points, lines, and polygons) and their attributes. It is widely used in web maps, GIS systems, and geographic data sharing scenarios. Common file extensions include .geojson or .json.
- How to Add GeoJSON File Information? First, open GISBox, click the "Service " tab on the left, and select "Vector."
Click the "Add" button in the upper right corner of the interface. In the "Add Service" pop-up window, upload the GeoJSON vector data as a file.
- Publishing a Vector Service Once the GeoJSON file is successfully added, a new service that we have successfully published will appear in the service list.
Publishing a vector service is generally done by default using the WFS (Web Feature Service) protocol. We can also choose other types of protocols for publishing, such as WMS (Web Map Service), WMTS (Web Map Tile Service), and MVT (Mapbox Vector Tile).
GISBox currently provides seven preview frameworks, mainly: Cesium, Mapbox, Leaflet, OpenLayers, Shanhaijing, ArcGIS, and QGIS. Clicking on the last two mainly provides tutorials on how to preview in ArcGIS and QGIS.
The generated service address can be directly applied to other related GIS platforms or in digital twin projects like Shanhaijing Visualization.
Through the above steps, users can easily add GeoJSON files and publish vector services in GISBox, achieving efficient sharing of geographic data and multi-platform application, providing strong support for GIS project development and geographic information visualization.
