Geofilter accepts location data via FTP file uploads or HTTP requests. GIS functions clean, transform and aggregate the data into streams of geo time series, trip segments, route maps and address elements.

Vehicle Tracking - IoT:
GPS devices used for vehicle tracking are susceptible to errors caused by signal reflections from buildings, system clock errors and static navigation-jumps when stationary. Geofilter can accept high volume data from GPS devices and smoothen it by removing outliers. Auto trip detection and address geocoding produce clean trip segments and route maps. We built Geofilter using our experience in building fleet tracking systems for OBDII GPS trackers manufactured by Teltonika and Queclink.

Mobile Apps:
Apps with geolocation tracking can use Geofilter to clean and enrich data. React Native Background Geolocation by TransistorSoft is a popular, battery conscious location tracking SDK for Android and IOS. Geofilter has inbuilt support for the file formats produced by the SDK. You can directly send data from mobile apps to Geofilter instance.

Mapping & Visualisation:
Auto trip detection feature identifies trips or journey segments in the location data. Geofilter produces GeoJSON LineStrings and Google Polylines representing routes. You can use GeoJSON and polylines for mapping and visualising routes on Google Maps, Leaflet mapping library etc.

Batch geocoding:
Match every data point to the nearest OpenStreetMap address.
