How to generate service area polygons with your AI

Connect CARTO to your AI client to turn travel times and distances into spatial data. Once connected, your agent handles the geometry generation.

Short answer

How can I make drive-time polygons with my AI?

Your AI uses the CARTO connector to run isoline calculations based on your specific time or distance constraints. You'll get GeoJSON polygons that represent your service areas or catchment zones.

The results.

What you get from this task.

The AI processes your spatial constraints into usable geographic shapes.

GEOJSON

Ready-to-use polygons

The AI generates GeoJSON files representing your catchment zones. You can drop these directly into your mapping software.

ISOLINES

Drive-time boundaries

Your agent creates isolines that show exactly how far a vehicle can travel within a set time limit.

THRESHOLDS

Custom distance limits

The AI builds polygons based on specific distance radii or travel time windows you define in chat.

HUMAN

Map validation

You must review the resulting polygons in a GIS tool to ensure the spatial logic meets your business needs.

The workflow

What your AI does when the request arrives.

The AI translates your natural language constraints into spatial operations.

  1. Define constraints

    Your agent interprets the specific time or distance thresholds you provide in your prompt.

    calculate_isoline

  2. Calculate boundaries

    The AI executes the geometry math to find the specific points that meet your travel criteria.

    calculate_isoline

  3. Format output

    The agent packages the resulting shapes into a standard GeoJSON format.

    calculate_isoline

  4. Deliver data

    The AI provides the final spatial data for you to use in your mapping applications.

FAQ

How this task behaves.

  • 01

    Can the AI create custom map styles?

    No. The AI only generates the geometric polygons; you must apply styling in your own GIS or mapping software.

  • 02

    Does the AI save these polygons to my local drive?

    No. The AI provides the GeoJSON data in the chat, which you can then save or copy.

  • 03

    Can I use walking speeds instead of driving times?

    Yes, as long as you specify the travel mode or speed constraints in your prompt.

  • 04

    Will the AI update my existing CARTO maps?

    No. This tool is for generating new isoline data, not for modifying existing layers in your CARTO workspace.

  • 05

    What format is the output in?

    The output is provided as GeoJSON.
