Cesium (focus on real-time visualization of spatiotemporal data)
- Cesium is a three-dimensional earth open source framework (can be used on multiple platforms and cross-platforms)
- Cesium is affiliated to AGI (Analytical Graphics Incorporation), and engineers from the General Motors Space Department of the United States initiated open source
Peripheral products
GIS develops from 2D to 3D to 4D. According to the different forms of BS/CS, it can be divided into the above categories, and Cesium has realized the leap from 3D to 4D
Advantages and disadvantages
advantage
- Pure BS framework, no need for any plug-ins
- The code is open source, all can be adjusted
- There is a complete learning document
- Support various 3D data, easy to be compatible with GIS, CAD, BIM, radar point cloud
- The display of 4D data is considered in the underlying data
- HTML5 is adopted (all mobile phones and Android can run); node.js supports data flow
shortcoming
- Compared with CS or stand-alone GIS software, such as ArcGIS/skeline, it lacks analysis capabilities
- Compared with 3D modeling software, such as CC/Sketchup/Cityengine, interactive model editing is not possible
- Compared with WebGis, the basic tool for map interaction that lacks threads needs to be implemented in cesium
- Feature services are not supported, and features cannot be edited under BS (cannot be dynamically edited on brower)
- Weak ability in the use and management of attribute data
What can Cesium do?
First of all, the data format it supports
what can be done
-
Supports multiple tags
-
Measure the data
-
Support particle system (game animation is basically completed by particle system)
-
Dynamic data display
-
simulated weather
-
Visibility analysis (what can be seen and what cannot be seen is displayed in red), visibility analysis (what can be seen and what cannot be seen), mobility display
-
Trajectory tracking (multi-target, single target)
-
sensor simulation
