Desk studies are a meticulous process whereby highly skilled geotechnical engineers commit multiple hours to research and the compilation of reports. Typical desk studies require the compilation of historical maps, first-hand research, ground investigation data, and site visits. 

Difficulties can arise when using early edition OS maps, six-inch geological plans, aerial photography, and post-war mapping – all of which can be of variable quality. Experienced and diligent cartographers create maps that are easier to use so take less time deciphering, but not every map meets these standards. This can inflate your workload and slow down your desk study phase. Using our high-quality InSAR data can reduce the time spent on this phase while contributing to completing an in-depth report. 

Core Difficulties 

Historical maps can be fraught with problems, they are often incomplete or feature irrelevant data. They can stretch back hundreds of years which means they don’t meet the same standards required of modern maps. This increases the difficulty of your desk research as you must identify which maps are usable and which cannot be relied on for accuracy or relevance. Historical maps are used to identify disused mines, although exactly which data set to use to find this information is not always clear, potentially delaying the process further. 

As you compile desk study reports, you will often find yourself relying on multiple agencies or individuals for data to complete your objective. Having a data set on hand such as the SatSense ground movement product allows insight to be gained – and reports to be completed quickly. 

Refusals of planning reports can lead to rework of the desktop study, increasing the amount of time spent and potentially delaying the project. Planning authorities are looking to see that all available, relevant evidence has been used to determine the best course of action for the more intrusive ground investigation.

Using InSAR to Improve Reporting 

Construction developers can be demanding as their site is relying on planning permission to be granted, in order to progress the project and start generating returns. They often run their site with a thin margin and will look to select a geotechnical consultancy firm with best value for money, while also considering the quality of work. 

Our highly accurate InSAR data is available instantly, with expert interpretation and analysis on hand to support clients. With this you can compile an up to date, detailed report quickly. 

InSAR data hasn’t been readily available until now. We are aiming to make instant access to high quality InSAR data a reality for every geotechnical engineer. We have lowered the cost barrier and improved accessibility by launching our own data visualisation portal.
