NavCom Technology, Inc. announced that Delta Data Systems, Inc. has completed the integration of its Pocket DLog software for topographic survey applications with NavComโs high-performance, high-accuracy, Real Time Kinematic (RTK) GPS equipment. With Pocket DLog, users of NavComโs RT-series receivers now have the ability to build three dimensional topographical maps. Pocket DLog is a robust mapping system that uses GPS to collect feature coordinates in a GIS digitizing process. This is a process through which geo-referenced objects are created and attributed as either point, line or area objects enabling the quick and accurate creation of topographical maps. Its primary fields of application are in field tiling, earth moving, mapping inland waterways, dredging and levee monitoring.
