🎁GeoTIFF Overlay in Maps

A single, structured view of each day's site activity that keeps teams informed and aligned

Drone surveys and aerial photography have become standard practice on construction sites but the imagery they produce usually ends up in a separate GIS tool or shared as standalone files with no spatial context inside the project management platform. When a project manager wants to compare the latest drone capture against the planned layout, or a site engineer needs to verify earthwork progress against the programme, they have to switch systems, manually cross-reference locations, and piece together the picture themselves.

Why This Matters

Construction sites change daily. Earthworks reshape terrain, temporary structures appear and disappear, and access routes shift as work progresses. Drone imagery captures this reality with precision but only if teams can see it in context alongside their tasks, zones, and planned layouts. When the imagery lives in a disconnected tool, the spatial intelligence it carries stays siloed. Progress verification becomes slower, discrepancies between plan and reality are spotted later, and safety or access concerns visible in aerial imagery don't reach the people managing the schedule.

What's New?

• GeoTIFF file overlay: Upload a GeoTIFF file and it renders directly on your project map as a positioned overlay, aligned automatically using the file's embedded geo-coordinates.

• Accurate geo-location: The overlay sits at the correct real-world position on the map, so what you see matches exactly where it is on site. No manual positioning or scaling required.

• Latest site imagery in context: View drone orthophotos, aerial survey captures, or satellite imagery layered over your project map without leaving VisiLean or switching to a GIS application.

• Visual progress monitoring: Compare planned site layouts against actual conditions captured in the imagery, making it easier to verify progress, spot discrepancies, and flag site access or safety concerns.

How It Helps

A Project Manager uploads the latest fortnightly drone orthophoto as a GeoTIFF overlay before a progress review meeting. The imagery sits directly on the project map, and the team can visually compare the as-built state against the planned layout identifying areas where earthworks are ahead of schedule and zones where access roads have shifted from the original plan, all without opening a separate GIS tool.

A Site Engineer checking safety conditions after heavy rainfall opens the maps view with the most recent aerial capture overlaid. The imagery shows standing water near a planned excavation zone, prompting the engineer to flag a constraint and delay the activity until drainage is confirmed a decision made in seconds because the imagery and the schedule live in the same view.

A Senior Planner overlays successive monthly drone captures to build a visual timeline of site progress. By switching between overlays, they can demonstrate to the client exactly how the site has evolved grounding programme discussions in photographic evidence rather than abstract schedule bars.
