GPS Data Preprocessing & Cleaning Fundamentals
Production-grade preprocessing architecture for cleaning, aligning, and projecting raw telematics into reliable trajectories.
RouteMatching is a working library of production-grade techniques for fleet telematics and mobility data processing. Every page is a deep dive — clean noisy GPS traces, align spatiotemporal streams, detect stops and dwell time, reconstruct trajectories, and snap them to a road network using probabilistic map matching.
The material targets mobility engineers, fleet managers, Python GIS developers, and logistics platform builders who have to debug the messy edge cases — signal loss, drift, memory bottlenecks, coordinate system drift, and ingestion at scale.
Pick a pillar below to start. Each one anchors a sub-tree of focused, Python-first guides with copy-pasteable code.
Production-grade preprocessing architecture for cleaning, aligning, and projecting raw telematics into reliable trajectories.
Transform continuous telemetry into discrete, actionable events with spatial clustering, dwell windows, and contextual enrichment.
Project noisy GPS sequences onto a road network with probabilistic models, then segment behaviour for downstream analytics.
Every guide pairs the architectural reasoning with concrete Python — vectorised operations, state-space estimators, density-based clustering, Viterbi decoding — plus the operational realities of scaling pipelines from a few thousand pings to petabyte-class fleets.
