Format Requirements for Importing Road/Railway Design XML Files
To generate a cross-section volume report, the user is required
to upload the 3 design files in XML format. These design files will be uploaded as Surface files. It is important that each file is represented by a single surface. If the user would like to use a single surface, duplicate and rename the Top Surface file and import it as the Bottom Surface.
Three LandXML files;
1 Top Surface (Pavement Surface)
2.Bottom Surface (The Datum Surface of Section)
3. Alignment
Top-surface.xml: includes a single TIN surface which defines the top surface of the design.
Bottom-surface.xml: includes a single TIN surface which defines the bottom (Datum) surface of the design.
Center-line.xml (alignment): includes 2D/3D Single line/polyline (which defines the center line of the road or might be a Ramp / loop Alignment) and the start run (begging of the alignment - 23985.68 in figure 1 example).
Start station: the user should add the defined first station (could be different than the begging of the alignment), the first station should be according to the following format “XX+XXX”, and according to the chosen interval the following next stations will generated.
The first station in figure 1 example is “240+00” (station for run 24000), and not “239+85.68”.
Stations Interval: the interval between the generated stations, according to figure 1 example the interval is 100 feet (between the first station “240+00” and the next station “241+00”).
Generate Cross Section Volume Report
To automatically generate the cross-section volume report, the user should choose to calculate the volume either between the top surface and the as-build surface (current flight or different date) or the bottom surface and the as-build surface.
The generated cross section graph, will include the 3 layers: top surface, bottom surface & as-build (DEM). The volume will be calculated according to two layers: top/bottom & as-build.
Requirements:
Base surface: top/bottom surface from the uploaded design.
Comparison surface: the as-build (DEM of a chosen flight).
Start station: the first station in the report where a cross section will be generated.
End station: the last station in the report where a cross section will be generated.
Section interval: the interval between the generated cross sections.
Factor Cut/Fill: the cut/fill factors for volume calculations.
