Developing a Mobile GIS for Field Geospatial Data Acquisition

Abstract

Field based and GPS assisted GIS are frequently used in various geoscience applications. Such systems deliver more advanced, time and cost effective tools than traditional field forms for information collection. At the same time, different systems are on the market. These systems mostly enable users to determine positions of geo-objects by GPS, and maintain functionalities to gather and analyze geometric information. The digital obtaining of the application's specific information is often underrepresented within these kinds of systems. This paper attempts to develop a system for gathering, integrating, analyzing, and visualizing spatial and aspatial information in electrical industry facilities. A PDA based GIS is extended to collect information in a beneficial manner, thus, adequately supporting the requirements of its users. Mobile GIS architectures, the components of a mobile GIS, and their impacts on gathering data are examined. The steps followed to design and develop a system for the electricity Transmission and Distribution Company are demonstrated. The results are presented and discussed in details in the paper.
