GIS Technician

Keep a water utility's map data right: fix a dataset that lands in the wrong place, repair a join that silently failed, geocode customer reports without hiding a neighbourhood, measure distances in the right projection, and make a map the board can trust.

What you'll build

Real portfolio pieces built during the course, not a certificate for its own sake. Each one is work you can show.

  • Data intake recordAn incoming dataset checked and fixed: what its coordinates are, how that was established, what had gone wrong, the fix that changed no values, and how it was proved.
  • Geocoding quality reportA quarter's complaints geocoded and checked: what matched and how well, what tied and how it was settled, what failed and why, and proof that the map hides no neighbourhood.
  • Notification analysisWhich parcels are within 150 metres of a proposed main, measured in the right coordinate system: why an earlier run was wrong, the corrected list and land area, and the checks at the edge.
  • Board map and recordThe complaints map specified for a board, rates not counts, classed to survive black-and-white printing, with the record that says where every number came from.

Description

Every CertClue course follows the same seven-part shape: fundamentals, the role translated out of job-posting language, a real working day, the job's recurring rhythms, a multi-day simulation, the portfolio you build along the way, and a handoff into your next move. Here is what that looks like for gis technician.
