Topographic map survey

　　Industry background

　　With the progress of science and technology,modern measurement technology is constantly developing,and the demand for precision of measurement equipment and stability in complex environments in field operations has greatly increased.The task of survey and design is also increasingly arduous.In practical field work,problems such as dense forest cover,environmental interference that cause RTK fixed speed to be too slow,receiving radio signals to be unstable,complex terrain that makes it difficult to obtain high accuracy,and frequent installation of base stations,all pose various challenges to survey workers.

　　Solution

　　Zhonghaida's Haixingda RTK system utilizes quasi dynamic measurement functions in the face of complex working environments,bringing historic changes to field survey work.

　　It adopts the intelligent RTK system of Haixingda,and cooperates with HDL all-around satellite external radio,manual,and Hi-Survey software.

　　Operation process:

　　1.Using the external radio(1+N)mode,set the relevant parameters of the base station and mobile station,collect the coordinates of control points,and set parameters;

　　2.The field industry uses the Hi-Survey measurement software legend code,which can be used for outdoor real-time mapping.

　　Program Advantages

　　Enabling"quasi dynamic measurement"improves the fixation rate and greatly reduces the probability of flying points;

　　2.Hi-Survey software supports legend coding,real-time mapping of the measurement interface,and customized graphic attributes and legend coding templates;

　　Hi-Survey software can create new codes or select Tsinghua Shanwei codes,CASS codes,etc.,which are saved during the measurement process

　　When selecting point coordinates,directly select the corresponding code in the description code box to facilitate rapid mapping for office work.
