Floodplain and Flood Probability Mapping Using Geodatabases
This research presents methods of creating digital maps for floodplain delineation and flood probability studies and storing them in a geodatabase. Methods for creating a geodatabase for water resources outside of a GIS are presented. The geodatabase follows the ArcHydro data model. Methods are …

USAGE OF VERY HIGH-RESOLUTION OPTICAL RGB SATELLITE IMAGERY IN GEO-INFORMATION EXTRACTION FOR FINE-SCALE MAP-MAKING
Maps are the fundamental elements of any navigation and localization system. With the fast expansion of urban areas and the increasing complexity of modern cities, traditional mapping techniques cannot meet the need for frequent map updates with enriched map details. In this thesis, we investigate …

INTELLIGENT PATH SEARCHING AND POSE ESTIMATION
… and heading reference system (AHRS), and digital maps. The proposed pose estimation has been validated using public and self-collected data and can be further extended to other kinds of sensor configurations with state and measurement constraints. Then, maximum entropy searching and …

Automatic Updating of Cartographic Databases
… points that are included in both files. The two digital maps may have different scales, different coordinate systems, and no identifying cartographic labels. In the absence of such survey control points, well-defined points in polygonal features such as building corners can be used. A prototype …

Location aware data aggregation for efficient message dissemination in Vehicular Ad Hoc Networks
… systems like satellite navigation and digital maps. The mechanism ensures that the network load is significantly reduced by using the passive clustering and adaptive broadcasting to minimise the number of exchanged messages. The incoming messages are fused by Kalman filter providing the …

A Novel Graphic Syntax: An investigation into how a GPS-enabled wayfinding interface can be designed to visually support urban recreational walkers’ situation awareness
GPS-enabled wayfinding interfaces (i.e. digital maps) are now commonly used as wayfinding devices in urban locations. While these wayfinding interfaces provide increasingly accurate geographic and routing information, little attention has been paid to how novel information design approaches may …
