The Research of Mobile GIS Power Distribution Line Inspection Based on Mobile SVG/J2ME

To deal with the contradiction between the line inspection business requirements for processing massive map data and the limitations which the line inspection mobile terminals have in processing performance, memory and storage capacity etc., this paper analyzes advantages of the Mobile SVG and J2ME in the mobile GIS, and proposes a mobile GIS line inspection program based on Mobile SVG and J2ME. The program organized map data by classification and block, generated static or dynamic SVG documents by GIS server, and made full use of J2ME platform's support for resource limited equipments to achieve the functions of GPS positioning, parsing SVG documents or XML attribute files and real-time displaying and browsing map. It makes up the low memory defect of mobile terminals, improves the data transmission efficiency, ensures the clarity of the map and improves the inspection quality.
