A new historical map and data service has been launched to give a clearer picture of any UK site's history and present state thereby helping environmentalists and developers plot its future.
The service, incorporates new high resolution historical maps, geology and ground stability reports and environmental data reports.
According to GroundSure business development manager Nicola Wild it enables 'faster and easier assimilation of information and therefore a more solid basis for site assessment and analysis.' 'The team at GroundSure has? developed a new range of products to match the specific needs of environmental professionals by producing historical mapping and targeted environmental data, ' she says.
'This results in faster and easier assimilation of information and therefore provides a more solid basis for assessment and analysis.' GroundSure has used new digitising technology to drastically improve the digital quality of the historical maps. It scans them at nearly double the market standard resolution and claims its digital map packages are better able to provide a more solid basis for assessing and analysing sites.
Wild claims the historical map pack 'contains the most comprehensive collection of historical maps dating back to the 1840's. Scanned at 508dpi (the market standard being 300dpi) it represents a step change in quality with double the resolution of the current market offering.
'With such a high level of quality and accuracy, you can see the difference at a glance.
Features jump off the page. The assimilation of information is more immediate.
'The subsequent analysis is therefore easier, faster and more accurate.' Each map is also individually geo-referenced, ensuring that deviation from the actual position on the ground is minimised.
The maps are site centred and orientated to the National Grid, which should allow clients to obtain a clearer and truer picture of the historical character of their sites.
The maps are available in 1:10,000, 1:10,560, 1:2,500 and 1: 1,250 scales.
Wild explains the service's environmental data report offers condensed data in a report format combined with aerial photographs, enabling the quick identication of potential risks and helping to give an immediate site overview.
The report includes a current site plan using the latest Ordnance Survey master map; current and recent historic aerial photography; an overview of data findings and Environment Agency groundwater ooding information.
She adds that the geology and ground stability report comprises current aerial photographs showing site location, articial and supercial deposits, bedrock and faults, recorded boreholes to 250m of the site boundary, historical surface and underground workings and current ground working all overlaid on current maps facilitating quick and accurate judgment of a site's condition.
