Deliverables

Three layers.
One piece of ground.

Every survey lands as a set of drawings over the same parcel. Here is the sample site, in the viewer we hand over with it.

Plate 01 — deliverable viewer

Look at the same ground three ways.

The orthomosaic stays on the left of the handle. Choose what sits on the right, then move the handle to compare. Drag it, or give it keyboard focus and use the arrow keys, Home and End.

Split at 50%. Left of the handle: Orthomosaic. Right of the handle: Thermal band.

Synthetic sample imagery. Not a survey, not a photograph.

Reading the layers

Each drawing answers one question.

Orthomosaic: What is there. Corrected imagery stitched into one tile, so a distance measured in one corner means the same in another.
Thermal band: Where to send someone. Relative warmth from a single pass. It points at a location; a technician on the roof decides what it means.
Contour model: How the ground falls. Lines at a stated interval, with the crest and drainage picked out, for setting out and for volumes.

Plate 02 — field report

Findings, pinned to the plan.

Move through the findings with the keyboard or a finger. Whichever one you land on lights up its exact point on the plan. Untick anything you do not want in the file.

Parcel: 18.4 ha
Surveyor: A. Selvakumar

Standing water on the north roof bayA-01 · Visual layerRoughly 210 m² of ponding traced across Block A. Worth a look before the next spell of rain.
Warm cluster in the array, rows 12 to 14A-02 · Thermal layerA group of modules reads warmer than its neighbours in the same pass. Flagged for a technician, not diagnosed.
Haul road edge has slumped near the gateB-01 · Contour layerAbout 14 m of the eastern shoulder has dropped away. Contours show the fall running towards the drain.
Stockpile 3 is larger than the last visitB-02 · Contour layerThe pile has grown towards the boundary. Compare against the previous surface before you plan the haul.
Silt building up in the south drainC-01 · Visual layerThe channel narrows over a 30 m run. Visible in the imagery and consistent with the surface fall.
