Cross section control

Compares measured crosssection to a cross section calculated from terrain model. Cross section is measured as breakline.

There is more information and testdata in 3D-Forum: Cross section control

Measured file

File that contains measured lines. Line can be measured from left to right or vice versa. Lines should have same surface id as used terrain model.

Terrain model

Terrain model for the theoretical surface.

Road alignment

Center line of the road.

Calculation width

Width for the cross section calculated from the terrain model.

Rounding

Rounds calculated section position to given value.

Selected

Only selected lines are calculated. Line is selected if any of it's points is selected in the group.

Along line

If checked, cross section is calculated along the measured line. Otherwise the points are projected perpendicularly to road alignment. Theoretical cross section is calculated along same line. Cross sections section number is mean value of it's endpoints.

All models

Laskee poikkileikkauksen kaikista elementtilistan malleista. Vertailu suoritetaan kuitenkin vain listalla valittuun malliin.

Control

If checked, height difference (DZ) is stored as control point to the measured point. Viivasta lasketaan aina poikkileikkaus kuvaan. Jos rasti on päällä, lasketaan myös tarkkeet.
