Mid-Level SpatioTemporal Query Events

Input Values

• startTime: which takes values in the form of "2012-01-22T00:00:00"
• endTime: which takes values in the form of "2012-02-22T00:00:00"
• xmin: The minimum x coordinate of the search region
• xmax: The maximum x coordinate of the search region
• ymin: The minimum y coordinate of the search region
• ymax: The maximum y coordinate of the search region
• eventType: Type of events to return. Multiple types can be specified in the form of a comma separated list.
• sortby: Allows the user to specify what field to sort the results by. The results will then be sorted by ascending order using that field. Options are startTime or endTimewhich.
• limit: Denotes the maximum number of event id's that the query will return in a single request.
• offset: The offset in number from the start of the list of results that meet the requirements passed into the method. Used to perform paging when used in conjunction with limit..

Results

• kb_archivid: Unique id for each event report
• eventtype :The event for which the results are returned.
• starttime:Start time of the event report
• endtime:End Time of the event report
• hpc_bbox: A bounding box that contains the returned event
• hpc_boundcc: A set of chain coordinates forming the polygon outline of the event (If present)
• frm_name: Name of Feature Recognition Method (useful to filter event types that have multiple reporting methods that may report at the same time).
