We have the latest state-of-the-art GPS surveying equipment. The Real Time Kinematic GPS allows topographic surveys and repeat surveys with sub-centimetre precision in x, y and z co-ordinates. The equipment is ideal for field mapping of environmental features and repeated surveys of environmental changes (e.g. fan deposits, river channel cross-sections). This GPS also allows the user to relocate survey points so that buried objects, instruments etc, for example can be easily found upon return.

In addition we have a range of traditional survey equipment such as EDM Total stations and levelling devices and a hand-held differential GPS.
We own a range of meteorological monitoring equipment that will suit a variety of needs. In addition to a portable automatic weather station we have a selection of tipping bucket rain gauges and associated dataloggers. We have humidity and temperature recorders and air speed monitors. Hand-held versions are also available to enable spatial wind investigations to be performed.

We own two ground-penetrating radar facilities. These can be used to investigate subsurface geological structures and engineering features and in a wide range of applications for the water industry and other environmental fields. For example, some of our clients have requested its use to identify the location of underground piping or for archaeological purposes.
We have what are widely considered to be the industry leading versions of GPR facilities – these are a RAMAC GPR and a Pulse EKKO GPR. These have been used, among other places, on Arctic glaciers, in Pennine peat bogs and in 17th century water gardens to establish the old underground water features.

We have a wide range of automatic datalogging facilities for use in lowland and harsh upland environments. Many can be buried with long-life batteries, and others can be powered by solar panels or other external battery supplies. Some of our loggers have up to 24 channels, and others are specially designed to be compatible with our robust field equipment. Loggers can be used to record data from monitoring probes at any specified interval. We currently have loggers located across the world and our expertise ranges from glaciated environments to wetland peat bogs and to arid zone environments, tropical rain forests and mine sites. At the moment we have around 40 loggers recording 24, 000 measurements per day in Upper Wharfedale alone.
