Stonex R25/R25LR Total Station - User Manual 92
Here:
Mileage is the stake mark of intersection point. Within the input format can’t be included certain characters
“K”, “k” and “+” etc. For example, 2224.224 can be input instead of K2+224.224;
North is the ordinate of intersection point;
East is the abscissa of intersection point;
Turn is the angle of one intersection point relative to the route (Turn angles of start point and end point
should be set to 0);
Radius is the radius of curvature of circular curve corresponding to intersection point. When route turns
left, the radius will be negative; Conversely, the radius will be positive. At the place of start point and end
point of route, the curvature radius value must be set to: 99999999.999 or -99999999.999;
Spiral Len is the easement curve length relevant to intersection point. Set to 0 in the situation where there’s
no easement curve.
NOTE:
• When using intersection point method, input data successively in accordance with mileage (small to
large) of intersection point. And the first and the last intersection point must be on the straight-line
segment of the road centerline.
• When using main point method, you can input data out of accordance with mileage of main point,
but don’t miss out any main point finally. It's recommended to input data successively according to
mileage magnitude in support of check and verification.
• The datum input with main point method can’t be viewed and edited in the form of intersection point
method, i.e., intersection point method will be disabled if import in the form of main point; But
differently the datum entered in the form of intersection point can be viewed and added in the form
of main point, except for deletion.
• Affected by precision of turn angle, there may exists deviation in main point datum converted by
intersection point datum.
• No matter what kind of method (main point or intersection point) you choose, normal stake out and
measuring can be executed based on the requirement of input of at least two valid records (two valid
main points or intersection points).
