Q: How to set the handheld GPS related parameters and coordinate conversion parameters throughout the country
Collect the application area of high grade control data in GPS receiver applied earth area (such as a county) find three (or more) uniform grade (accuracy better) or GPS "B" network, the best point is around without interference of electromagnetic wave, vision, the satellite signal is strong. To the local surveying and mapping management department (such as: the local bureau of Surveying and mapping, surveying and Mapping Institute) Gauss plane coordinate copy these points of the Beijing 54 Coordinate System (x, y), the elevation of H and WGS-84 coordinates of the geodetic coordinates (B, L), the high H.
Q: Mountaineering to buy a professional GPS or Mountaineering Watch
Can be downloaded in general maps, satellite maps, and even contour maps, which features far more than handheld GPS or mountain climbing watches, you can better meet the needs of mountaineering.
Q: Professional handheld GPS GARMIN (DR) how to use
Handheld GPS purposes, the measurement of soil area, linear navigation, auxiliary fishing waypoint navigation point information, traffic data display, such as the use of functional machines should be used manual
Q: Handheld GPS charge is not into electricity what is the reason
Two, solutions:1, for other chargers, or data lines try, or clean the charging port.2, boot into recover mode advancsd advanced mode, select the wipe Battery, remove battery traces.
Q: My cell phone: HTC Hero 200Question type: Internet softwareMy work needs to locate, record, output, and input GPS coordinates. Track record measurement, coordinate transformation. So would you have a professional security software under the table, so go out with a mobile phone or a PAD, or N equipment back to survey the tired,
Taobao to enter the online shopping, mobile phone navigator on the line, I suggest you download the Careland navigation map, or tiger map
