Mapping and measurement
From satellite pre-screening to targeted visual site verification
A satellite report can filter a site and frame questions, but cannot confirm every current parcel-scale condition. A verification mission starts from those questions and documents areas where visible conditions may affect a decision or justify specialist investigation.
What needs to be checked
The client provides the boundary, any previous report and a list of specific questions. The mission may document visible access, occupation, recent structures, surface drainage, vegetation, local slopes, obstacles or differences between available information and the observed situation.
This is not an unguided overflight. Points of interest become a planned set of photographs, routes and overview images. Where vegetation, relief, access or airspace prevents observation, the report records that limitation rather than inferring an answer.
How the two products connect
The public Tepoztlán example demonstrates the first level: a land pre-screening report built from public sources, with a 72.50/100 result and explicit limitations. The Corasol report separately demonstrates a drone mission format with trajectory, orthophoto and deliverables. They are not the same project; together they illustrate the transition from remote screening to close-range site documentation.
How the mission is prepared
- 1
Describe the site and decision.
Location, area, environment, urgency and expected deliverables.
- 2
DataTerra checks feasibility.
Airspace, access, weather, equipment, resolution and permissions.
- 3
Receive a clear quote.
The proposal defines capture, processing, outputs, limits and conditions.
- 4
Access the results.
Agreed files and viewers are delivered through the client workspace.
Possible deliverables
- ✓geolocated photographs organized by question;
- ✓a recent orthophoto of the accessible area;
- ✓annotations or a table of visible observations;
- ✓a surface model where it adds useful context;
- ✓overlay with the supplied boundary or previous report area;
- ✓a PDF distinguishing observed, unseen and recommended follow-up checks.

Images do not prove ownership, legal boundaries, geotechnical stability, absence of contamination, permits, planning compliance or structural capacity. A visible access route is not necessarily a legal right of access. Lawyers, notaries, surveyors, engineers and environmental specialists remain responsible for their respective investigations.
Frequently asked questions
Must I buy a satellite report first?▸
No, but a report or a clear question list helps focus the mission on the issues that matter.
Can the drone confirm legal property boundaries?▸
No. It can document visible features and overlay a supplied boundary, while legal demarcation requires authoritative sources and qualified professionals.
What happens when an area cannot be seen?▸
The report identifies the limitation and may recommend a walkover, topographic survey, geotechnical study or another appropriate check.
A mission-specific quote
Each mission uses only the methods required by its goal. GCPs, thermal or multispectral cameras, 3D models and reports are included when relevant and confirmed in the quote. RTK is mentioned only when its availability is confirmed explicitly. Submitting the request does not trigger a charge; DataTerra replies with a proposal.
Coverage and feasibility
Operations are available in Mexico and Colombia depending on location and operator availability. Airspace, site permission, access, weather, risk and required equipment are checked before confirmation.
