Geographical Information Systems (GIS), together with Computer Aided Design (CAD) form an integral part of the work that WMC provides for its clients. This includes the visual representation of data and the integration of data management solutions. The company has dedicated teams within its offices worldwide, who are responsible for the application of a wide range of software solutions. These technical personnel have vast experience in a number of areas including:
- Data capture, conversion and processing.
- Scanning, geo-referencing and re-projecting data.
- Two-dimensional cartography.
- Three-dimensional geological and hydrogeological visualization
- Spatial and geospatial analysis.
- Acquisition and processing of remote sensing data, ranging from satellite and aerial images through to radar, lidar and geophysical data.
- Database design and programming.
- Data audits.
Projects that demonstrate Data Management and GIS include:
| Title: |
Three-dimensional visualisation for modelling projects
|
| Location: |
UK |
| Client: |
The Environment Agency |
| Description: |
An important aspect to the creation of a hydrogeological model is the ability to visualise the geology as an aid to designing the mathematical computer model. It is important to see the relationship between the geological surface outcrop and topography with the underlying geology and hydrogeology. It is not only important to visualise the information but also to have the ability to transform this into hard data that can be imported into any computer model. This was an important aspect of several modelling projects for the Environment Agency, which included models of the chalk in the Kent, Avon and Bourne areas of southern England. The GIS was also used to process spatial data such as rainfall, soil and land use types into a format suitable for the models.

| Title: |
Watchtree foot and mouth disposal site
|
| Location: |
Cumbria, UK |
| Client: |
DEFRA |
| Description: |
The client commissioned WMC to develop a database to monitor the environment around the site, this included groundwater and surface water monitoring, geochemistry, meteorological data and the ecology of the site. The database developed can be queried fully based on individual sites or parameters sampled. The results of which can be see plotted on time series graphs within the database. The database was linked to Arcview 8 GIS to enable spatial queries of the database. The GIS is also a complete record of all the activity on the site, this includes local and regional data, historical data and all construction phase details. Non spatial data such as engineering details were linked in as hyperlinked pdfs to spatial features in the GIS. The GIS will become a permanent record of the site and will be a useful source of information for educational purposes too.

| Title: |
Pit planning/closures
|
| Location: |
USA |
| Client: |
Various |
| Description: |
GIS plays an important role in the study of the hydrology, hydrogeology and geology of the planning, ongoing monitoring and the planned closure of open cast pits. Together with CAD it also provides detailed three dimensional visualisations of the sub-surface geology and structure. This provides data for the studying and modelling of a wide range of problems from dewatering through to the analysis of hydrochemistry and geochemistry. The GIS is backed up with comprehensive databases with links to modelling and geochemistry software packages.
