The cloud GIS web client development platform is based on the modern Web technology. It is the unified Javascript client for the SuperMap cloud GIS and online GIS platform products.


Component development

  • Supports component development under Vue framework, including map component, rich geographic visualization components, chart component and basic GIS component, etc.
  • MVVM mode (model view ViewModel) is adopted in architecture design, and other frameworks are compatible, such as Angular and native H5 development.
  • More than 100 sets of themes are built in the component, and the theme styles of all components can be switched with one click.

Big data visualization

  • Provides unified API and visualization for distributed analysis service and data flow of SuperMap iServer.
  • Supports various temporal and static visualization effects: scatter plots, thermograms, honeycomb plots, trajectory plots, O-D plots, flow diagrams, 3D architectural drawings, wind maps, etc.

Integrates the commonly used maps and chart libraries

  • Map development library supports: Leaflet, OpenLayers, MapboxGL-JS, iClient Classic.
  • Chart development library supports: ECharts, D3, MapV, DECK.GL.

Vector tiles

  • Supports MVT and standard coordinate systems like Web Mercator, WGS84, CGCS2000 and local coordinate system.
  • Supports interaction and style configuration, including query, selection, highlight, etc.

Client computing

  • Integrates turf.js, and supports client computing like geospatial, topology, equivalence, measurement, etc.
  • Client can achieve high performance analysis and calculation without interaction with server.


It is a 3D client development platform based on WebGL technology, which can be used to build 3D GIS applications with plug-ins free, cross-operating systems and cross-browser.


Full functions

  • Supports high-performance loading and display of massive, multi-source, and heterogeneous data such as images, terrain, maps, vectors, manual modeling data, underground pipelines, tilted photography models, BIM, laser point clouds, and 3D field data.
  • Supports efficient rendering of massive real-time dynamic data.
  • Supports 3D geospatial analysis and analysis result output: through-view analysis, visual field analysis, skyline analysis, sunshine analysis, profile analysis, openness analysis, etc.
  • Supports efficient visualization of voxel grid.
  • Optimizes distance and area measurement based on land surface.
  • New function of 3D geospatial query and relations judgement based on GPU.
  • Supports polygon clipping of videos, and can only display the videos in specified area.
  • Newly supports label thematic map making based on point cache and style modification in real time.
  • MVT can support 3D characters, which optimizes loading and browsing performance.
  • MVT and S3M layers can support traction line and icon, and the custom images can be set as background.
  • MVT can set filter, and the style, explicit and implicit of the specified object can be searched and modified through condition setting.

Data security

  • Supports the loading of terrain image service encrypted by cache stream.
  • Supports terrain, image, S3M layer, WMTs, body object data to set custom request header.

High reality

  • New fireworks particle effects.
  • Supports scan line with texture.
  • Optimizes the display effects of border lines.

New function of real time analysis for geological body

  • Supports real time sectioning analysis.
  • Supports polygon clipping.
  • Supports cylinder and polygon excavation of geological body.
  • Supports virtual drilling.
  • Supports geological model expressions of exaggeration, explosion, etc.
