The Development of Web-based Multimedia GIS for Electricity Transmission Right-Of-Way Maintenance System
Managing encroaching objects within electric-transmission right-of-way is an important consideration for many electricity agencies. Electricity Generating Authority of Thailand (EGAT)is the transmission power line agency that generates, acquires and transmits electric energy to other electric agencies under the law thereon and neighboring countries. Digital Airborne Patrol System (APS)has been set up for a monitoring system for transmission lines and right-of-way using photo and video cameras. There are many images and video files from APS which can be linked to location. Oracle Spatial is used for storing the transmission line and right of way together with location data which link to such recorded media files. Web-based application is developed to allow user be able to query, analyze and manage right-of-way encroachment. Open geospatial standards, WMS and WFS, are used in the application. Several tools are developed to allow user to edit and update detected encroaching objects. Linear Referencing System (LRS)function in Oracle Spatial is applied in the application which it enables user to identify the encroaching object or point interest on the linear distance from the electricity station. The purpose of this paper is to present how to integrate the open geospatial standards, web technologies, spatial database and multimedia (images and videos)to build the Web-based multimedia GIS for ETRMS (Electricity Transmission Right-Of-Way Maintenance System).
