PROCESS VECTORS AND ADJUST THE NET
We show you an example:
create new project. Fill out some information about the project. Select your local cordinate system from list. If you don’t find the system you needed, please select “setup” to create your local coordinate system.Click new to create coordinate system, input parameter. Remember to select the coordinate system you create after click return.
Add raw data.
Click input-Add gps observation data (or click toolbar). Select the data file you need, click ok, then you will see the progree:
when all raw data is added, the control net shape is shown as the following figure.
Process vectors,
Click process- process all or click it, it will display the whole process of processing. It will take you a few minutes to process all vectors, the time spend depends on the size of all raw files and the lenght of vectors. After accomplishing process a vector, the vector’s color will turn red on gray from green. When a vector’s variance of dual-differential fixed solution is more than 3, the vector will turn red (it means the result of processed vector is eligible). Otherwise, when a vector’s variance is less than 3, the vector will turn gray (it means the result of processed vectors is unqualified. In this condition, we need to re-process the vector by change process parameter. For example, as you double click vector Q009-Q007 it come out the dialog of process parameter setting:
by changing some process parameter, we can re-process the selected vector. Changeable parameter referred above includes Mask Angle and epoch interval. If we change the value of Mask Angle to 20 degree, the vector’s variance is more than 3, there is no need to change parameter- The maximum variance’s value is 100.
Net adjust, input known point. Click input, station coordinate, it will show a dialog box. In this network we suppose Q007 and Q041 are known points. Select Q007 and Q041 then input their coordinates in above dialog box.
Adjust the network.
Click adjust network adjustment the software will adjust the net (including wgs-84 adjustment, 2d restricted sdjustment and altitude fitting). The detailed net adjustment result includes: loop closure report. wgs-84 (3d) adjustment result, 2d adjustment result, altitude fitting result.
Adjustment result output and print. Click report— result report output, you will get detailed result report (the format is txt) Certainly you can choose some item you needed to output from the following figure list, such as vector solution list, resolve vector, loop closure, wgs adjustment result, 2d restricted adjustment result, altitude fitting, etc. Also you can output the final result coordinates of all surveyed points and a map file of DXF format. Click result REPORT of adjustment.
