CEDRA-XsectionsTM



CEDRA XsectionsTM is an ArcView® GIS extension, included with the CEDRA AVcadTM software, that enables the user to create points using cross-section data. Shown below is a typical cross-section with three surfaces each drawn in a different color. The points comprising the cross-section are defined in terms of station and elevation, while the cross-section is defined in terms of a station value. CEDRA XsectionsTM will (a) generate ASCII files, for each of the surfaces shown on a cross-section, containing station, offset and elevation values for each point comprising the surface, and (b) when used in conjunction with a baseline process these ASCII files to create points. These points will be stored in individual shapefiles, with each shapefile corresponding to a surface.

CEDRA-XsectionsTM

CEDRA-XsectionsTM allows the user to process up to 8 surfaces at a time. Using the annotation shown on the cross-section, ASCII files containing the station, offset and elevation values for each of the surfaces identified by the user for processing will be established. Each surface will be represented by a single ASCII file and will have its layer or level number appearing in the filename.

Once the ASCII files have been created, the user can superimpose these files with a baseline. Shown below is a simple straight line baseline in which ASCII cross-section files were superimposed upon. Each ASCII cross-section file is converted into a shapefile and added to the view. Stored as attributes in the shapefiles are the station, offset and elevation values associated with the points comprising a cross-section, as well as, the computed coordinates.

CEDRA-XsectionsTM is an ideal tool for converting cross-section data appearing in a .dgn, .dxf, or .dwg file into plan data.
