Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing.

[0026] As shown in Figures 1 to 8:

[0027] GPS coordinate conversion:

[0028] In the application of GPS positioning measurement, since the GPS positioning results are based on the WGS-84 coordinate system, the surveying and mapping results in my country are generally expressed in the Beijing 54 coordinate system, and most cities use local coordinates to avoid the inconvenience caused by Gauss projection deformation. independent coordinate system. Therefore, it is necessary to convert the GPS coordinates into the corresponding coordinate system. Depending on the starting data of the known control points and the accuracy requirements of the application field, the corresponding coordinate transformation models are also different. The handheld computer integrated with the GPS function adopted in this embodiment has a low CPU operation speed and a small memory, and more calc...

Abstract

A method for integrating information of satellite positioning and remote sensing as well as geography based on mobile device utilizes embedded windows CE operation system built in mobile device and its provided-embedded development environment including embedded GIS data model and integration of GPS and GIS as well as integration of GIS and RS to realize position data collection and remote sensed image loading as well as superposition of remote sensed image with vector map.

Description

technical field [0001] The invention relates to the field of mobile space information collection, in particular to a mobile device-based satellite positioning, remote sensing and geographical information integration method. Background technique [0002] GPS (Global Positioning System)-Global Positioning System, mainly realizes the positioning of the mobile terminal through multiple satellites. The mobile terminal receives the GPS information and processes it by itself or the network service center to determine the actual location of the mobile terminal. Since former U.S. President Clinton promulgated a decree to stop the S / A policy on May 1, 2000, the civilian code will not be interfered, which greatly improves the accuracy of civilian positioning. At the same time, this also accelerates and expands the application of GPS in all walks of life. With the wide application and development of GPS technology, many different types of GPS receivers have emerged. Currently, there a...
