Where Heat Meets People

A successful message describes what the software attempted. These five checks describe what the workshop must actually produce.

  1. 01

    Load

    Declared GeoParquet, expected CRS and exactly 16,659 features.

  2. 02

    Schema

    The required heat-exposure field exists and contains values.

  3. 03

    Style

    The renderer uses the real field and its classes contain features.

  4. 04

    Analysis

    The frozen expression returns the expected selected count.

  5. 05

    Export

    Reopen the PDF and inspect the map, legend, conditions and attribution.

The rescue rule

If you are more than 30 seconds behind, open the next numbered project state. This is recovery, not failure.

The bounded observation

In this frozen 29 July 2026 snapshot, 105 of 16,659 H3 resolution 9 cells, 0.63 per cent, meet the map's declared upper class boundary of 40,000 person-kelvin per square kilometre.

This is not a health threshold. Land surface temperature is not air temperature or individual heat risk. The result uses one daytime scene, modelled population and an author-chosen hexagonal support.

Exit ticket

This evaluates the teaching, not you.

1. How did you finish the workshop?
2. What end-state check would you add to your own GIS workflow?
3. Which one-hour follow-on would you genuinely attend?

Keep contact separate

Do not write your name, email address or confidential information on this card. Optional contact and course interest use a separate action and do not affect workshop participation.

Responses are workshop and product feedback. They are not presented as academic research findings.
