6, Magnifier function

Q:Saying that we have a project in front of it is to do so, it is surprising that there are wood: It is really unexpected, basically not, the accuracy is not enough!

Q:I am a handheld GPS precision is low, how to use to be able to improve certain accuracy: Look at the maximum accuracy of GPSIf the difference accuracy can reach 1cm you can connect CORS single base station and other network RTK way to achieve the corresponding accuracy

Q:I am a handheld GPS precision is low, how to use to be able to improve certain accuracy.: If the carrier phase measurement function is not available, you have the maximum accuracy of GPS accuracy of 1-10This can only improve the observation environment using SBAS and other ways to improve the accuracy

Q:Handheld GPS positioning, can be directly uploaded to the computer, and the computer has a scalable map to mark the upload point. The above system, now there are 20Such as the title, I want to achieve the final function: through the manual to a point, with a hand-held GPS locator will be recorded in the specific latitude and longitude, and sent to the network in real time, for my computer to mark these points on the map. If you can directly enter the site of some of the information, directly to the above is the bestIf you have the above equipment, please indicate the scientific name, and the specific application industry.Thanks.: 10 classification layer management, you can hide / show layer.11 support batch import export data.12 support for drawing straight lines, curves and any line segments, can change the color and width.

Q:Handheld GPS purchaseHandheld GPS navigator!Is mainly used for tourism, I said is not a mobile phone, is a more professional handheld GPS navigator for travel outside! Handheld GPS navigator can voice navigation?: If it is only used for general tourism, then hundreds of pieces of GPS is enough, go to the computer city to see, there must be sold, or go to your city to look at the outdoor store

Q:Handheld GPS, the measurement of arable land, fixed point and circle test, which is more accurate,: If the area is measured, are almost. However, if the measurement point is only the case, the dynamic GPS is now the general error can be guaranteed within 3cm, the total station can be guaranteed to the millimeter.

Q:Hand held GPS coordinate conversion method: Two. To coordinate the coordinate data of the control points obtained provide technical support unit of Beijing Unistrong companies around the branch responsible person to calculate the coordinate transformation parameters conversion parameters, or to obtain their own conversion conversion software. After the conversion parameters are calculated by the prompt input handheld GPS. Only after such a setup, after all the soil in the region when the coordinates of the GPS read out the coordinates of the point for the Beijing 54 coordinates.

Q:Highway measurement with GPS I do not know which of the base station settings and mobile station settings I are very vague, to the instrument to build a coordinate system how to build the relevant issues to me: For long tunnels, the conventional measurement of large bridges has the following limitations:1, long tunnels, bridges and other structures generally require the measurement level of four or more. With conventional measurement methods, often adopt the measure to increase the number of methods to extend the observation time, time consumption and labor consumption to try to improve the accuracy of.2, the long tunnel and bridge for the complex terrain region difficult, conventional control measure for visibility and network shape, often cut down the workload is quite large, so the measurement of the cost of a large, hard work.Link control network of high precision 3, long tunnel and bridge and low precision and route network, although with adjustment methods can be overcome, but because of the terrain conditions are difficult, the measurement workload to its connection, and is not too easy. In practical work, the control of the structure and the measurement of the route are often out of touch.

Q:Handheld GPS brand rankings: SIBAOIn the GNSS coordinate precision and attributes, "SIBAO" has a professional GPS handset, GIS i-PPP GIS, a mobile data collector, GIS, high precision GIS, high precision measurement of RTK complete product structure, to form a comprehensive solution to the spatial information industry scheme. Set of SIBAO products awarded the Beijing independent innovation product identification certificate, satellite navigation and Engineering Excellence Award and other professional awards. At the time, location, navigation and other comprehensive applications, Unistrong successful implementation of hundreds of large projects, services in many national key projects, won the national honor.MagellanGarmin

Q:Magellan GPS handheld why so many people choose not to say that the map is not good: Each brand has its own unique, if you only care about a map, then you think of the handheld too one-sided
