Kaihua Xu, Puyao Qiao, Yuhua Liu, Jian Cheng · 2009
This article introduced the design and implementation of real-time correcting remote sensing data based on the handset witch integrated 4S functions. Introduced the function and status quo of the 4S integrated system, given the development environment and related technologies of the 4S integrated handset correcting remote sensing data, explored the design method of the system's hardware and software. Using appropriate optimization algorithm to load remote sensing data fast, using GIS map overlay to collect real-time high-precision GPS geo-data, it can collect real-time, accurate mass of GPS information, achieve the accurate corrective of the remote sensing map, then send the corrected real-time data to the center through GPRS module witch embedded TCP/IP protocol. Combined with the advance of the WINCE system and the integrated development environment EVC perfect supports for the GDI interface, it can facilitate the design of correcting system, easy operation for user, become an extremely important field of the handheld device in field prospect.
