Interactive Visualization of Diverse Datasets Using 3D Tile Point Clouds

VISAGE (Visualization for Integrated Satellite, Airborne, and Ground-based data Exploration) aims to provide visualization and analytic capabilities for diverse datasets in an interactive user interface. Proof-of-concept use cases are centered around the Global Precipitation Measurement (GPM) mission's Ground Validation (GV) program, which provides a wealth of intensive, coincident observations of atmospheric phenomena from a wide variety of ground-based, airborne and satellite instruments. These data have diverse temporal and spatial scales, variables, and data formats and organization.

Key technical challenges include:

- 3D data rendering and visualization of multiple diverse datasets on a web-based platform

- 3D data interrogation via map user interface

- Temporal alignment of data with diverse time scales and resolutions

- Computations on data fields across instruments and platforms

To address these issues, the VISAGE project is working with cloud-native serverless technologies to render data as 3D Tile Point Clouds for display in the Cesium geospatial 3D global mapping platform.
