File of input data for the solution of direct geodetic tasks

This text file with *.tpr extension can be created in any text editor from a text file with the data received by an electronic tacheometer.

It has following structure:

.TPR

// Filling of a sheet of calculation of a linear resection

// (at polar survey the given line is absent)

BEG INTERSECTION

// type of angles

ANGLE 0

// type of the measured angles (not obligatory parameter)

LR J      

// a point of standing and its coordinates

POINT1 NAME1 X1 Y1

// a point of prompting and its coordinates

POINT2 NAME2 X2 Y2

// a direction angle

DIR G M S

// installation of MO

MO G M S

// installation of a limb

LIMB G M S

//

HINSTR j

// format of entered points for calculation

FORMAT N D L G M S H E V A B I W P

// calculated points
