Mobile Geographic Information Systems


Mobile Geographic Information Systems (GIS) allow us to take spatial data out into the field and (optionally) capture new spatial data. These systems comprise a mobile computer, either a tablet computer or PDA, running GIS software equipped with a Global Positioning Device (GPS) or Global Navigation Satellite System (GNSS) to provide a location. Depending on the needs of the project, these systems can provide <10m or 3-5m or <1m accuracy on the ground.
Being database driven, structured data can be used to determine the cartographic style and control data capture, ensuring standards can be enforced. These can either be national standards, for example for land use classifications, or client specific standards, based on agreed recording pro-forma. This makes data captured in this way ideal for subsequent analysis and reporting, the best solution for gathering monitoring information about archaeological sites (e.g. condition surveys) or for validating data produced by desk based assessments in the office or for walkover surveys aimed at locating potential new sites and monuments (eg as part of Rapid Coastal Zone Assessment Surveys).


It is possible to take any spatial data out into the field this way including client supplied plans and maps, historic and modern Ordnance Survey maps, Historic Environment Record (HER) datasets or even LiDAR data, aerial photos and associated transcriptions.
Any data captured out in the field can then be loaded into our desk-based GIS and database applications ready for analysis and reporting, removing the need to enter data from paper-based recording forms.


Using open platforms such as Google Maps, it is also possible to use mobile GIS to deliver interesting and informative content to the general public, for example as part of landscape tours and other outreach activities. In this way we can deliver rich GIS data to any mobile device, optionally equipped with GPS, including SmartPhones, iPads and tablet computers and using the internet can provide links to further sources of online information, either pre-existing resources such as online HER pages or Wikipedia pages, or we can create online resources for particular projects including rich multimedia (pictures, videos and interactive elements).
