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
Defects of conventional measurement methods:1, the specification of the length of the attached wire, the length of the wire and the length of the wire between the nodes have strict requirements, generally for high grade roads are required to meet the requirements of the first line. In this way, the length of the wire shall not be more than 10 km, or the length of the wire shall not exceed the length of the wire attached to the attachment of the wire length of 0.7 times. This requirement is generally difficult to achieve in the actual work, often appear super standardized operations.2, to collect the starting point for the general route of measurement and control is difficult to ensure the same measurement system, the measurement and measurement, often in the city of control points mixed together, the compatibility between systems, if the starting point is not compatible, is bound to affect the quality of measurement.3, serious damage to the national site, the impact of measurement operations. Due to the country's basic control points, mostly completed in 50s and 60s, after more than 30 years, some point due to the needs of economic construction is destroyed, and some people because of the lack of knowledge of human destruction. Route survey work in these areas, often in the 50 km above all can not find the wire control points. The quality of the route control survey is not guaranteed.4, ground visibility difficulties often affect the implementation of conventional measurement. The control points of the general route shall be located within 300 meters from the course. Due to visibility reasons, it is difficult to meet the conditions, even in a large range, and the dense shrub forest area, simply can not implement conventional control measure.
Q: I would like to ask the GPS handset and GPS receiver (Surveying and mapping qualification application needs) is there a difference? If yes, what is the difference?
This is the case, GPS handheld refers to a thin hand, while the GPS receiver refers to the RTK host, equivalent to the base station in our industry said. The general application of Surveying and mapping qualifications are required for this application, referred to as RTK (1+1) set, level, theodolite, total station, walkie talkie, technical personnel.... And so on, are essential equipment.
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: Can a handheld navigator connect a cell phone? Thank you
Mobile navigator can downloadOther purchases can not beNow basically use the phoneEasy update and operation
Q: I am a handheld GPS precision is low, how to use to be able to improve certain accuracy.
If you can join the CORS network, the accuracy of decimeter to centimeter level.
Q: Hand held GPS coordinate conversion method
By the 84 coordinates to Beijing 54 Coordinate. A collection of 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" dot, point the best is around without interference of electromagnetic wave, vision, satellite signal. 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: Jia Ming etre20 handheld GPS good
Jia Ming eTrex 20 has an enhanced 2.2 inch screen, a color rendering effect of 65 thousand TFT, a readable display in the sun. Durable waterproof, but also upgraded the interface to retain the existing hardness and toughness, to withstand dust, dirt, moisture and water erosion, these are not the legendary navigator opponent.
Q: How to use the handheld GPS whole watershed investigation
The critical value is an object from a physical state to another physical state, a physical quantity to meet the conditions, which is equivalent to the stagnation point in Mathematics
Q: How to hand GPS eTrex H data to the computer
"Shaanxi skmax navigation information Limited" GARMIN proxy (GARMIN official website can be found), contact (Xiao Hou) the hope can help to you, if you do not understand what we see on the Internet, may at any time, contact us!
Q: How the German born handheld GPS Mu meter, I want to buy?
Brian GPS handheld measuring instrument type 30A is a German born Mu launched a new professional Mu instrument, using high sensitivity GPS receiver chip, GPS super signal tracking capability, satellite positioning easily.
