PHT Hands-On Workbook

Working with GIS Selections

Objective: Create selections of highway sections using a GIS map.

Specifics: GIS maps provide a graphical means of selecting highway sections for the PHT analysis.

Use: GIS selections can define a sub-set of the overall highway network or define a single continuous route for a corridor analysis.

Tasks:

  1. Create a GIS Selection and associated it with the highway data
  2. Select highway sections using various methods
  3. Compile a GIS selection into a continuous corridor
  4. Select the highway data records for analysis using the GIS selection
A screen shot shows the Settings tab under the Study tool where the user can use the Create GIS selection icon to select a shape file. A screen shot shows the directory structure where the user can browse files in the Sample directory on the PHT installation CD. A screen shot shows the GIS Shape File window where the user can select the file and use the Open button to access the file contents. A screen shot shows the GIS Selection Properties window, where the user can select data fields from the GIS shape file.
A screen shot shows the Settings tab under the Study tool where the user can view the directory associated with the GIS Selections folder and select the desired file. A screen shot shows the map generated for the I-35 corridor as an example of the data presentation from the GIS shape file.
A screen shot shows the map generated for the I-35 corridor where the user can apply the manual selection tool to highlight a portion of the corridor on the map.
A screen shot shows the map generated for the I-35 corridor where the user can apply the attributes selection tool to automatically select a portion of the corridor on the map. A screen shot shows the Query Wizard window where the user can select query inputs from fields, operators, functions, and values.
A screen shot shows the map generated for the I-35 corridor where the user can apply the compile tool so the selected highway sections are handles as a single corridor. A popup window provides the user with the opportunity to complete the GIS selection into a continuous corridor or cancel the operation. A popup window confirms that a continuous corridor has resulted from the previous operation.
A screen shot shows the Settings tab under the Study tool where the user can review the Properties of the file in the GIS Selections folder. A screen shot shows the popup window for GIS Selection Properties where the user can review the data fields and verify if the compilation was successful and a continuous corridor is the result.
A screen shot shows the map generated for the I-35 corridor where the user can apply the Highway tool to select a set of highway sections for analysis. A screen shot shows the popup window for Choose PHT Database where the user can browse the folder for the desired file.
A screen shot shows the popup window for Pavement Health Track where the user can choose whether or not to make a copy of the database containing only the selected records. A screen shot shows the popup window for Pavement Health Track that gives the count of highway sections that were selected.
