Forensic-grade geospatial analysis • In-memory processing
Configure which location data quality flags to filter. Forensic Standard preset recommended for legal/investigative use.
Define the radius around each Point of Interest (POI) to detect when devices came within range of specific locations you're investigating.
Radius around each POI for detecting proximity. Device must be within this distance to count as a visit. Typical values: 100-1000m depending on location type (building vs. neighborhood).
Automatically discover locations where devices stayed for extended periods by analyzing both spatial proximity and time spent. Uses a four-stage algorithm: spatial grouping, coherence verification, temporal filtering, and overlap merging.
Maximum distance between consecutive location points to be considered part of the same dwell. Recommended: 100-200m for buildings, 500-1000m for neighborhoods.
Minimum time a device must spend at a location to count as a dwell. Filters out brief stops. Recommended: 10-30 minutes to distinguish actual stays from passing by.
Minimum number of location points required to identify a dwell. Higher values increase confidence but may miss shorter dwells. Recommended: 3-5 points.
Control which location data points to include based on signal quality and accuracy. Forensic Standard is recommended for legal/investigative use.
Keeps high/medium accuracy. Rejects impossible movement, grid locations, cell towers.
Understanding the Two Analysis Methods
POI Proximity Detection
Checks if devices visited specific known locations you're investigating (addresses you provide in POI CSV). POIs appear as labeled circles on maps with your custom radius.
Automatic Dwell Detection
Discovers unknown locations where devices stayed for extended periods. Dwells appear as colored squares on maps (Blue: <30min, Yellow: 30-120min, Red: >120min).
