What this score means

Most of this role's work is still genuinely hard for AI to do. Physical presence, bodily skill, high-context judgment, direct human care - the things that don't translate to text.

If you're in this role, here's what to do now

You're not in the firing line today. But the frontier moves. Build enough AI fluency now that you can direct it for the parts of your work that could benefit. People in unexposed roles who understand AI become unusually valuable inside their organisations.

Most of the routine task inventory in this role can already be done by a capable LLM. That doesn't mean the role disappears - it means the shape changes, and one person can credibly do the work of several.

If you're in this role, here's what to do now

Stop doing anything an LLM can do. Your edge is judgment, relationships, taste, and the parts of the work that require you to be in the room. The operators who notice this first and redesign their workflow around it will be paid for those things; the ones who cling to the old task list will compete against AI at AI's prices.

Where a project with Alex usually starts for this role

These are the highest-importance tasks a language model can already handle directly today. In a typical engagement the first wins come from building workflows around these, so they stop eating your team's time.

  1. Calculate latitudes, longitudes, angles, areas, or other information for mapmaking, using survey field notes or reference tables.

    O*NET importance 3.7/5 · directly AI-automatable

  2. Complete detailed source and method notes describing the location of routine or complex land parcels.

    O*NET importance 3.4/5 · directly AI-automatable

  3. Perform calculations to determine earth curvature corrections, atmospheric impacts on measurements, traverse closures or adjustments, azimuths, level runs, or placement of markers.

These are the highest-importance tasks AI can already handle when paired with the right tools and context. In a typical engagement the first wins come from building workflows around these — usually the difference between an LLM that can technically do the job and one that actually does it inside your business.

  1. Check all layers of maps to ensure accuracy, identifying and marking errors and making corrections.

    O*NET importance 4.3/5 · AI can do this with workflow tools

  2. Design or develop information databases that include geographic or topographic data.

    O*NET importance 4.2/5 · AI can do this with workflow tools

  3. Monitor mapping work or the updating of maps to ensure accuracy, inclusion of new or changed information, or compliance with rules and regulations.

Every role has three or four wedges like these. Finding them takes an hour. Turning them into a workflow your team actually uses takes a few days. Talk to Alex about a project →

Methodology

This role's exposure score comes from Eloundou et al's 2023 GPT task labels, aggregated by O*NET importance within each O*NET-SOC code, then bridged to UK SOC 2020 via ISCO-08 (ONS Vol 2 coding index) and US SOC 2010 (BLS crosswalk). Employment and median pay come from ONS ASHE Table 14.7a, 2025 provisional. ASHE covers employees only, so self-employed workers are not counted.
