A Geographical Information System (GIS) is a computer system for capturing, managing, analysing and presenting location-based data. It integrates cartography, statistical analysis, database technologies and other data to provide a baseline of information which can be used and updated throughout the entire life of a project.

When dealing with location-based data, the use of GIS can help to gain a competitive advantage by enhancing the ability to: • Makeeffectivedecisionsbyprovidingtheabilitytosolvecomplex spatial problems such as site selection, customer targeting and engineering design, thus improving the quality and timeofdecisionmaking.

• Fullyleverageexistingorganisationaldatabyintegrating cartography, databases and statistics into an information baseline that can easily be interrogated.

• Visualisespatialpatternsandphenomena,therebyassisting effectivecommunicationwithstakeholdersand clients.

• Improveoperationalefficiencyandreducecostsbyintegrating disparate data sets, enabling real-time monitoring, scenario planning and data sharing to provide cost efficientandtargetedservices.

We are happy to provide a demonstration of how you can use GIS in your organisation in order to deliver a focused and high quality service to your clients.

The Practice

We provide GIS services directly to private and public sector organisations that do not have their own in-house GIS capabilities orprefertooutsourceorout-taskpartoftheirwork.Inthepastwehave provided GIS services to organisations within the environmental, geo-environmental, remediation, ecological and transport sectors, howeverwearehappytoworkinanysectorandareflexibletonewchallenges.

We recognise that our clients require high quality service delivered at a cost that provides value for money. We offer a professional, friendly andcustomisedservicetomeetyourspecificrequirements.

We offer our GIS services in data capture, processing, analysis and general mapping to facilitate decision support and data presentation.

Data capture:

We digitize and geo-reference scanned data and compile features from any spatial datasets such as base maps, aerial photographs, and other drawings such as CAD plans. In addition we capture, process and geocode non-spatial datasets to integrate into GIS projects. We implement UK and European data formats and standards for the review of data quality and accuracy.

General Mapping and Data Analysis:

We process and perform spatial analyses to produce a wide range of outputs such as high quality maps and 3D visualisations. We haveestablishedstrongtieswithanetworkofleadingdatasuppliersthat allow us to utilise appropriate datasets (the Ordnance Survey productsuite,UKMap,LiDARandmanyothercommerciallyavailabledatasets)tosuityourspecificprojects.

GIS for improving operational efficiency:

Our team provides both technical and strategic advice to design, implement and manage projects to provide a total GIS solution. We workcloselywithourclientstoidentifyopportunitieswhereGIScanbe used to improve business processes and service provision.

StrategicDataManagementforLargeSitesandLandPortfoliosWe can use GIS to create geographically searchable databases whichlinkthousandsofdocumentsbaseduponfeaturelocations,co-ordinatesandattributes.Thisoffersaquickwaytosearchforlocation-based records particularly for complicated sites with a large amountofbackgroundinformation.Itcanbeofconsiderablevaluetoclients wishing to collate information associated with a global portfolio ofsitesandrequiringameanstoquicklyinterrogateinformationatagiven site.

Case Study – Daedalus : GIS based document management systemCampbellReith was appointed by SEEDA (now HCA) to manage and co-ordinate the EIA for the redevelopment of this 180 hectare former MoDsite.Giventhehugevolumeofinformationavailableonthesite,muchofwhichhadbeenpassedoverbytheMoD,GISwasusedtocreate an interactive database that allowed all data applicable to a particular location or feature to be easily interrogated. The database included reports on structural condition, heritage, archaeology, asbestos, drainage infrastructure, utilities, ordnance, contamination and ecology and was used to inform the baseline conditions assessmentandprovidetheSiteManagerwithatoolformanagingthesite.

Case Study – Historical Site Information DatabaseWe have developed an in-house geographically searchable database containing our site investigations since the 1960’s. This provides uswithaneasyandquickwaytosearchforinformationduringtheappraisal of sites at the initial project stages.

GIS can greatly assist the process of land quality assessment, geotechnicaldesignandvalidation,wasteassessment,earthworksand material management.

In this regard, we have used GIS to:

• Informthedesignofgeotechnicalandremedialsolutionsand provide ground modelling to support cost assessments and feasibility studies.• Provideatooltoplansiteinvestigations,viathedevelopmentof conceptual site models, site constraints plans and integration of data sets such as borehole logs, analytical data, historical mapping and site proposal plans. • Analyseandvisualisesoilandgroundwatercontaminationdata forboththepurposeofriskassessmentandtodemonstratethe achievement of remedial objectives.• Integratewithspecialistgeotechnicalandenvironmental softwareandanalysistoolstoallowustointerrogatecomplex datasetsefficientlyandaccurately.Thisisinvaluableforlarge engineering and remediation schemes.

CaseStudy:RemediationValidationOn behalf of a remediation contractor, we utilised GIS to assess the performance of a programme of in-situ persulphate treatment on phenol concentrations in the soil. By applying spatial analysis and mass balance calculations to data from treatment samples, we were able to demonstrate to the contractor that the diminishing phenol concentrations had achieved remedial regulatory objectives.

This facilitated a targeted investigation which considered the areas of concern and subsequent assessment of remedial measures.
