Where we work
Agresca works wherever reliable data is hard to get. Below are recent Copernicus Sentinel-2 views of five reservoirs and rivers across these regions. They are sample views, not client projects.
Approach
A short brief sets the question, the sources and the confidence you need.
Satellite imagery, records, instruments and site visits, gathered for the place in question.
Every finding is cross-checked, sourced and rated before it reaches you.
Engineers and analysts turn findings into reports, dashboards and decisions.
