Supporting FORESTRY restoration activities with satellite imagery
Having used satellite imagery for the last 20 years, Jimmy Wilson, a forester at ECKY Surveys in Scotland, wanted to explore how Geocento could assist him with his most recent project - mapping a former opencast mine over a densely forested area in Scotland. Read what he said about his experience.
“I was asked to survey the ‘site and soil types’ over an extensive area of former opencast working following its ‘restoration from surface coal mining’. A basic tool for almost any field survey is a good aerial image at a workable resolution and one that can also be used in GIS applications. In this instance the most recent image was almost 5 years old and showed the actual workings when the site was abandoned. No airborne images were available of its present structure and this made surveying/mapping very difficult and inaccurate.
Using a drone was a possibility but would be expensive. On approaching Geocento I was informed that satellites passed over the country every day and depending on the weather and cloud would give me the required image. A sample was provided and I selected the image area. This covered 125 km2 and could be zoomed to at least 1:7000. The image was only 2 days old and provided the best mapping tool possible.
Looking at the wider forestry picture this would be an ideal tool/source for all survey work e.g. recent storm damage, areas of clear fell, crop health surveys etc. A forest is a dynamic, growing and ever changing environment and images of even one year old often do not clearly illustrate routes for crop access, etc”.
