Mapping & Photogrammetry
65-Acre Site Mapping & Progress Documentation
Recurring aerial photogrammetry used to create a shared spatial record of site conditions as the development advanced.

Overview
Project overview
This 65-acre development had grading, utilities, pads, access, and staging moving in parallel. Project teams needed a repeatable way to see the whole site without relying on scattered stills or waiting on a full survey cycle.
Recurring aerial photogrammetry produced a date-stamped orthomosaic and shareable web map. The map became a common spatial record for planning, field coordination, and later comparison.
Objective
Documentation objective
Create a repeatable spatial record of site conditions and progress so later visits could be compared to an earlier state.
- Shared site context for project teams
- Grading, pad, and access reference
- Utility and staging visibility
- Progress documentation over time
Methods
Capture method
Aerial photogrammetry was flown on a consistent footprint so later captures could be compared. Overlapping stills were processed into an orthomosaic and published as a web map.
Browser measurements are useful for coordination. They are not a substitute for a stamped land survey.
Deliverable
Interactive orthomosaic
Pan, zoom, and review site layout directly in the mapped record.
Delivered outputs for this project were the orthomosaic, shareable web map, and site imagery.
Why it mattered
A shared picture of changing conditions
On a site this size, pads, trenches, stockpiles, and access routes can change between visits. A versioned mapped record keeps those shifts visible.
Technical considerations
The orthomosaic and web map are a shared spatial record of observed conditions across approximately 65 acres. Measurement depends on the capture plan for each visit. The record is not a boundary survey, an as-built certification, or a pay-quantity document.
