Building Geospatial Intelligence Services for Latin America

Most geospatial tooling is built with North America and Europe in mind.

We built OnCoord to provide geospatial services focused specifically on Latin America — where POI coverage, addressing, and mapping consistency can vary dramatically between regions.

One application built on top of those services is Dorado, a location prospecting tool that scores neighborhoods using population density, economic activity, POI density, and nearby competitors.

The interesting part isn't really the frontend.

It's the APIs behind it.

const [poiResp, actResp, popResp] = await Promise.all([
  fetch(`/v1/poi_density?lat=${lat}&lon=${lng}`),
  fetch(`/v1/activity?lat=${lat}&lon=${lng}`),
  fetch(`/v1/population?lat=${lat}&lon=${lng}`)
]);
Enter fullscreen mode Exit fullscreen mode

Dorado combines:

  • /v1/population
  • /v1/activity
  • /v1/poi_density
  • /v1/poi_nearby
  • /v1/reverse
  • /v1/autocomplete

The map itself uses a dynamic hexagonal grid generated directly in the browser. Each visible cell is scored in parallel, while competitor proximity is calculated client-side to avoid hundreds of API requests.

export function cellRadiusM(zoom) {
  if (zoom >= 14) return 250;
  if (zoom >= 12) return 500;
  return 1000;
}
Enter fullscreen mode Exit fullscreen mode

One of the goals behind OnCoord is making these services composable.

The same APIs used by Dorado can also power logistics systems, mobility analysis, market research, geocoding workflows, and autonomous mapping applications.

The broader goal behind OnCoord is making geospatial infrastructure for Latin America easier to access programmatically.

  • Have a list of addresses in Latin America that need geocoding?
  • Need elevations, slope, aspect, or population for a coordinate dataset?

Send it to us — we're happy to process Latin America datasets for free. support@oncoord.com
