The GROMA program allows coding the points on the coordinate and measured data lists. When measuring using instruments that allow the point code reporting, the codes can be marked during the measurement in the field and so obtained information can be used during processing by the GROMA program or other consequential programs.
The point code can be formed by any alphanumeric string up to the maximum length of 20 characters. Twenty characters are fully sufficient to allow unique point identification and does not cause a significant increase in the volume of the coordinate files. The GROMA program transfers the codes for all the outputs to the descriptions (e.g. for an automatic placement of marks) pursuant to the attached Code table.
