Drone mapping services in Tiverton

The eastern side of Tiverton has been under sustained development for a long time now, in phases, with infrastructure going in ahead of housing in places and behind it in others. Sites like that accumulate history: a spine road built to one level, a drainage basin formed to another, a phase boundary that moved twice.

A dated aerial record is worth more on a site with that kind of history than on a clean greenfield plot, because half the questions that come up later are about sequence. What was formed by when, what level was it at, where did the temporary access run before the permanent one opened.

The town sits where the Exe and the Lowman meet, with steep valley sides to the west and much gentler farmland east towards the motorway. Those two halves fly differently. A steep valley site needs the flight height set against the highest ground, not the lowest, or the resolution across the site varies more than the client expects.

The gentler eastern ground is close to ideal for mapping: open fields, low hedge density by Devon standards, and long uninterrupted sight lines. It is one of the easier places in the county to get a clean terrain model over a large area.

Tiverton Parkway sits out on the main line east of the town, and the corridor around it carries employment land and logistics as well as the station itself. Rail-adjacent work is its own discipline: flights near an operational railway have to be planned with the line's controller, and that is arranged well ahead rather than on the day.

For anything in that corridor, the useful early question is how close to the boundary fence the survey actually needs to go, because the answer changes the paperwork more than it changes the flying.

The centre keeps its wool-town inheritance: a mixture of ages, some substantial nineteenth century buildings, a castle and a canal basin, and plot patterns that were set long before anyone drew a site layout. Recording an existing building in that context is model work rather than map work, and the flight has to get round the back of things.

Base to Tiverton is about half an hour up the A396 or the motorway, so it comfortably sits inside a single visit even when a job needs both a block survey and a set of oblique passes over a structure.

The Grand Western Canal runs east out of the town as a linear feature eleven miles long, and linear assets of that kind are one of the clearest arguments for aerial capture. A towpath, an embankment, a bank line or a hedge boundary running for miles is slow and expensive to survey on foot and quick to fly.

Corridor work is flown as strips along the alignment and processed as one continuous dataset. Where the subject is a bank or an embankment rather than flat ground, angled passes go in alongside the straight down grid so the face is recorded as well as the crest.
