The program is a “general purpose” calculation and drawing package for surveying work. It can accept data in a variety
of forms including that from data recorders, process this data, produce drawings and export the data in a
variety of export formats.
All processing is carried in memory and the results saved to disk at the end of a processing session.
To start a new job select File then New.
This will set up a new job ready for work. If the aim of the session is simply to process some
topographical data and print or plot the results, then the user can proceed with the work and exit.
When you exit, the program will ask whether you wish to save the data and if “yes” is selected
it will allow you to name the file and store it using the windows file management procedures.
If the job is to be a ongoing project, it is better to set up the final data file at the start by selecting
File again and then Save as to record the new file name.
This exercise is to process a small topographical survey where the spot heights
have been observed with a Total station instrument and recorded in the field as Bearing, Distance, Slope Angle
and Height of Prism. These were then entered into a file using the SURV00 data entry program ready for processing.
In the field, the survey started from S112, observed a new station S120, occupied that station and closed
off to S113. S113 was then occupied and later reoccupied for more data.
To process the data select “Topo” and then “Reduce Stadia” and then complete the following menu:
The reduced points are stored by the program and the reduction report is sent to the file “creek3.lst” which is as follows:
