Post Processing GPR Data
Post-processing GPR data provides numerous advantages in the field of utility surveys and subsurface investigations. The collection of data can be conducted swiftly on-site without constant scrutiny, allowing for the rapid coverage of large areas. This efficiency is crucial for projects with extensive site requirements.
Post-processing allows for the simultaneous viewing of multiple data images, facilitating the identification of linear features. Furthermore, various filters can be applied to the data images during post-processing, enhancing the clarity of information and refining data that may appear unclear or inconclusive on-site.
In areas characterized by high service congestion, post-processing GPR data typically yields more detailed and accurate results. Considering this, post-processing is essential for generating higher-quality final deliverables. Providing a comprehensive and refined output for clients involved in diverse construction, engineering, or subsurface investigation projects.
Post Processing GPR Guidelines
M1/M1P – EML: Orthogonal search transect at ≤10m intervals and when following a utility trace, search transects at ≤5m intervals. Used where density of services is typical of an undeveloped area.
M2/M2P – EML: Orthogonal search transect at ≤5m intervals and when following a utility trace, search transects at ≤2m intervals. Used where the density of services is typical of suburban area or where the utility services cross a boundary of survey area.
M3/M3P – EML: Orthogonal search transect at ≤2m intervals and when following a utility trace, search transects at ≤1m intervals. Used where the density of services is typical of a busy urban area or for clearance surveys prior to operations.
M4/M4P – EML: Orthogonal search transect at ≤2m intervals and when following a utility trace, search transects at ≤0.5m intervals. Used where the density of services is typical of a congested city area.

A Thoroughly Professional Service
At Subscan we send a full team of specialist engineers out to every drain jetting job no matter how small it might appear. It’s part of our commitment to every customer. Our experience means that you can be sure of a top quality, professional service, whether we’re there to carry out one of cleans and unblocks of your drains, sewers and interceptors or grease traps; or we’re carrying out a pre-planned maintenance programme.
Case Study
Client:
Wessex Water
Project type:
Underground utilities and topographical survey
Location:
Taunton, Somerset
Overview
Subscan were appointed by Wessex Water to carry out a full underground utilities and topographical survey to areas within Hinkley Nuclear Power Station and collate all information into one document.
Subscan were appointed by Wessex Water to carry out a full underground utilities and topographical survey to areas within Hinkley Nuclear Power Station.
This is an ongoing project due for completion on site Christmas 2018 and will be produced in a complete CAD DWG format with relevant PDFs. All high resolution photos from site and written day to day survey reports will be collated into one document by our surveyors and presented to the client on completion.
Client Testimonial
“The Subscan UDS team of surveyors and drainage engineers helped our minor works team out again and did a thoroughly professional job. We will continue to work with Subscan on LNE projects throughout the region.”
