Auto-Profiler Tool

The auto-profiler allows you to layout a centerline and then place station lines along the centerline at a specified spacing and width. The stations are then used to generate a profile shape file that contains at least one profile for each station along the centerline. The stationing must overlay at least one raster surface. The tool can simultaneously generate multiple profile shape files by intersecting one or more raster surfaces with a single set of stationing. The raster surface is typically a surface that represents an elevation value. Allowable raster formats are ESRI GRID, TIFF, FGDBR, SDR, and IMAGINE IMAGE. Each point in a profile shape file represents a depth (or elevation) that was dynamically extracted from a raster cell intersected by a station line. These profile points can then be viewed in a 2-D graph or the points can be exported to a comma-delimited ASCII text file.

auto-profiler-dialog-1 The build profiles tab is where the centerline is built and the station lines generated. Once the centerline and stationing are constructed the profiles are built from here. A centerline coordinate system must first be established prior to building a new centerline. Once a centerline is built it can be used to generate a preview of the stationing layout and also can be repeatedly used to generate stationing profiles.
auto-profiler-river-1 The centerline shapefile can be seen here overlaying a raster grid surface representing river bathymetry.
auto-profiler-river-2 When the build stationing button is pressed, permanent stationing is built and labeled in accordance with the spacing specified and a profile shape file is generated, one for each raster surface intersected. The profile points seen here have been classified using the elevation value field in the profile shape file attribute table.
auto-profiler-dialog-2 The figure here shows a listing of the profile shape files made when the build stationing button was clicked.  When at least one of the shape files in the Select Shapefile(s) list is checked a listing of the profile stations is shown in the list box seen below. In order to graph profiles, print profiles to the PDF map book, or export profiles to an ASCII text file, at least one station from the station list must be selected.
The profile plot seen here represents station 5+00. Other stations can be viewed in cross section simply by selecting the station from the dropdown list seen immediately below the graph.
