Aggregations Service Overview


The vector aggregations capability gives users the ability to summarize a vast amount of vector data rapidly and easily by location, keyword, date/time, etc. Aggregations allow users to poll larger areas for more information before narrowing down their searches to eventually reach the specific data they desire to download. Aggregations also give users the ability to run analytics such as change detection and discovering zones similar to an area of interest. In addition, in order for users to easily discover what values for a set of vector fields are available in a given geographic area, a specific kind of term aggregation called 'facets' is available. Users can take those facets and use them to construct specific queries to discover the specific items they are interested in.
