GEOTECHNICAL SOFTWARE specialist and consultant AF Howland Associates is developing a geographic information system to access and interrogate ground investigation borehole records and site summary information for Anglian Water.
The water authority admits it has not maintained its records in a readily accessible way, and it often needs to check whether work has been carried out near new sites.
The new stand-alone system creates a project symbol on a background map of Anglian Water's region. Users simply click on a project and then interrogate the database for more information.At a larger scale, individual borehole positions are shown. The system uses Howland's borehole software Geodasy to create borehole records for viewing on screen or as hard copy.
The data is stored in a raw form, either as Geodasy or AGS files, and can thus be manipulated and processed.
Previews and printouts are generated in real time and do not rely on scanned images. Howland says this is important, because using scanned images means data in the records cannot be processed electronically. The storage and process time involved with large scanned images limits the use of GIS, it adds. Access to the raw data means the functionality of the system can grow with the user's needs.
Howland says the system is ideal for organisations with a defined area of interest and an accumulating wealth of data, and recent developments in GIS technology have meant that such systems have become affordable for all organisations.
