Query broadcasted events worldwide and visualize them using spatial aggregations.

The service filters thousands of online news sources of the last 24 hours mentioning occurred protests or demonstrations. We constructed a web mercator spatial grid having a grid size being optimized for geographic visualization. Each grid cell is enriched with a count attribute representing the number of news article related to locations of the corresponding grid cell.

The service uses the impressive data source provided by the Global Database of Events, Language and Tone (GDELT) Project (https://www.gdeltproject.org/).

The service aggregates locations where some kind of protest took place using geospatial intelligence operations. The geospatial results support the GeoJSON and Esri Features format out of the box.

Every geospatial result support the GeoJSON and Esri FeatureSet format out of the box. All endpoints support an optional date parameter for filtering the results. For best performance, the serverless cloud-backend calculate the geospatial aggregations of the last 24 hours between midnight and 1 AM UTC. The serverless functions save these geospatial features for the last 90 days and yesterday should be the latest available date. Without specifying a date, we have to calculate the geospatial features of the last 24 hours on-the-fly.
