Most GIS analysis errors trace back to unclean input data rather than flawed methods; this course builds the unglamorous but essential skills to catch and fix those problems first. Participants clean and validate genuinely messy real-world spatial datasets throughout.
Spatial analysis built on dirty data produces confidently wrong answers, yet data cleaning receives far less training attention than analysis itself. This course corrects that gap, covering topology error detection and correction (overlaps, gaps, and slivers), geocoding cleanup and address matching for tabular location data, and coordinate system and projection error diagnosis.
Participants also work through deduplication and attribute standardisation techniques, validating field data collected under real-world conditions, and building repeatable data-cleaning workflows so quality checks happen automatically rather than being rediscovered on every project.
By the end of this course, participants will be able to:

This course is ideal for anyone who prepares spatial data for analysis or reporting.

The course fee includes training materials, software lab access, a data-cleaning checklist and workflow template, facilitation by an experienced GIS data quality specialist, and a certificate presented at the close of the programme.
