Abstract

Abstract A hybrid method of ecological habitat survey and mapping is presented, bridging paper-based methods and mobile electronic procedures. The hybrid approach uses a hand-held PDA with real-time dGPS to map habitats and record habitat attributes. It retains paper field maps to facilitate ecological decisions and to overcome the need for field surveyors to operate a fully functional mobile GIS system. The transition from paper records to a full GIS implementation is bridged by secondary digitisation in which a GIS specialist,trained in field survey procedures, interacts routinely with the field surveyors, throughout the field season to assure data quality standards. The methodology is practical and affordable, particularly if there are multiple field surveyors.
