Drone mapping services in Saltash

Almost everything about Saltash relates to getting across the Tamar. The road bridge and the Royal Albert Bridge beside it carry the A38 and the main line into Cornwall, and the approaches, junctions and land either side of them are permanently in some stage of study or improvement.

Infrastructure of that kind is corridor survey work: long strips flown along an alignment with heavy overlap, plus oblique capture where a structure or an embankment face has to be recorded rather than just plotted.

The naval facilities downstream on the Devon side carry restricted airspace, and the river is narrow enough here that a site on the Cornish bank still needs that checked properly rather than dismissed as somebody else's problem.

This is one of the places in the coverage area where the answer to whether a specific plot can be flown depends entirely on which side of a line it sits, so the check is done against the actual boundary, not against a general impression of the area.

The land drops hard to the water on both sides, and the Tamar is tidal well upstream of the bridges. A survey that includes the foreshore, a quay or a slipway is timed to low water, and a survey of the bank itself needs angled passes because a steep face is not visible from directly above.

The estuary also produces its own local wind behaviour, funnelled along the water, which can make conditions at the bridge quite different from conditions half a mile inland.

Away from the river, the growth is on the western and northern edges of the town where ground is gentler and sites are more conventional: block surveys, contours, cut and fill quantities on sloping farmland.

Saltash is about an hour and ten minutes from base, so a job here is a planned day rather than an add-on, and it pairs naturally with anything else in the east Cornwall or Plymouth area on the same trip.

The waterside quarter drops so sharply to the river that conventional access on the old streets is expensive and awkward, which is the whole reason aerial recording gets used here. The same gradient makes the operator's position the real planning question: there are streets in this town where there is nowhere sensible to stand at all.

That is settled on a site visit rather than from a map. Where a launch point cannot be found close to the subject, the flight is planned from further out at a greater standoff, which changes the resolution and is worth agreeing with the client before rather than explaining afterwards.

Above the old town the post-war estates at Burraton and out along the Callington road are ordinary, straightforward flying by comparison, and most of the everyday development work here happens on that side.

The bridges themselves are not survey subjects for a job like this, but they are unmissable context in every dataset produced here, and their airspace and structure clearance form part of the planning for any site near the crossing.
