Project Impact
Comprehensive site documentation
Reliable base for DPR preparation
Reduced fieldwork, faster approvals
Business Requirement
The client, a heritage consultant, required mapping of a 400-acre heritage site in
Orchha for landscaping planning. The site, an island-like formation surrounded by a
river, contains over 10 temples, forts, and palaces, and the documentation was
needed to support a DPR submission for UNESCO World Heritage Site status.
Proposed Solution
We deployed an RTK-grade drone for photogrammetric survey along with DGPS for
site documentation, covering the entire 400-acre site as well as a 300-metre buffer
zone around it to support the DPR preparation and government submission.
Challenges Faced
Several areas of the site were inaccessible due to the surrounding river and sloped
terrain outside the fort walls, making it difficult to place ground control points.
Scorching summer heat also limited fieldwork to specific time windows each day.
Outcome
The project was delivered successfully with complete topographic, contour, and
vegetation documentation across the 400-acre heritage site, supporting the client's
UNESCO submission.
