Using satellite images for measurements.

What if a drone can’t be used for aerial measurements? Last year, we were asked by a client to provide some aerial imagery to help with a query regarding the positions of some elements of a construction site compared to the positions stated in a planning application. The area concerned appeared to be spread across a couple of kilometres squared with the only space suitable for Take off/Landing (TOAL) appeared to be a couple of Byways Open to All Traffic … Read More

A quick multispectral drone survey of a field.

Agricultural imaging of a newly planted field by drone. On one of my walks during the Covid-19 ‘lockdown’ I happened across a field which had been planted during the previous winter. Several storms since it had been plated had done a huge amount of damage, washing what appeared to be a huge amount of soil, and crops out of the field, leaving it is a sorry state. I thought it would be ideal to use the field as a target … Read More

Drones, or UAVs are tools that can provide a lot of data, here we produced a small colourised height map of the immediate area for a castle ruin in Shopshire, as well as a short video. The impressive ruins of Hopton Castle lie to the west of the town of Craven Arms in South Shropshire. It was subject to a siege in 1644, and left in a state of ruin from at least the 18th century. However, in 2007, work … Read More

Drone mapping of abandoned quarry workings

by D C on December 28, 2018 with No Comments

On Titterstone Clee Hill, just outside of Ludlow in Shropshire, there are some old, long abandoned quarry workings, ripe for an example of drone mapping. Using a Mavic pro drone, and Maps Made Easy, a pre-planned UAV flight was designed and flown. In all, 80 photos were taken and stitched together. The resulting images, once submitted to Maps Made Easy, were then used to generate a small 3D model of the area. The resulting images that were stitched together, are … Read More
