Pegger set up Instructions

Before you start with Pegger, the appropriate files typically are prepped in ArcGIS.

From the DEM file you create

1. Contour shape file with appropriate contour interval. Typically select 1 ft contour interval. It provides for a better pegging alignment than a standard 10-ft contour map

2. Create also a 10-ft contour shape file (why, will be explained later

3. Create a slope class map. It helps in visualizing where to go with the pegged routs and which area to avoid

4. IMPORTANT!!!! The layers you just created have to be stored directly under the c-drive. Folder and file names CANNOT have any empty spaces. Use underscores

for example ---Local Disk (C:) > St_Ed_GIS_Data

Start AcView

Check Extensions Pegger, Spatial Analyst checked

Check create new project > check “as a blank project

Click on New then Project > Rename > type the Project name (e.g. St_Ed_Project)

Then click “Open”

To add themes (or layers) click on +

Then navigate to the proper directory where the layers are

Select the desired layer (e.g. Kl_st_ed_contour.shp), click OK

Add both the 1 ft contour.shp and the 10 ft contour.shp layer

The layer gets added but does not yet display.

You can change the display lines, etc by double-clicking on the layer theme and select line color, etc

To help with the pegging process it is useful to add additional layers such as slope class, to help with identifying critical areas and hillshade to help with terrain visualization

Again click on the “ Add Theme” button, navigate to folder.

Slope classes and hillshade themes are rasters, so make sure to select “Grid Data Source” in drop down menue

Slope class breaks have to be set now to the desired values. Double click on the slope class layer, then click on “Classify”

Then select the desired colors (double click in the color box) and type in the desired slope class range and breaks - click “Apply” button

To delete a theme click on “ Edit” > “Delete” in the GUI

Starting the Pegging Process

create new theme for pegging

Create new road theme

View > new theme

(the one you are going to peg). Make sure to select “line”

Make the new road theme active by clicking on the layer in the Table of Content (Start Editing)

Open now the table to create the necessary fields to store grade info and road names

Add fields for “Grade” and “Road_Name” Edit > Add Field

Close table view and open “Setup Pegger” to finish the setup process

Contour theme > select the appropriate contours. Make sure to select the 1 ft contour theme

Elevation field, should show the appropriate cont our interval (e.g. 1 ft)

Grade field and road name

	If Elevation Field is grayed out, click on drop down window of Contour Theme
If elevation field does not show up, then go back to contour theme, select from drop down menu anything and try again. Usually just hung up so need some shaking pick any other field to wiggle the memory, go back and pick elevation again from selection and it should work Select the appropriate drop-down field for Elevation, Grade Field and Road Name

Usually click NO.

To set the appropriate snapping tolerances

Theme > Properties, then

in the window click on Editing and set the desired snapping tolerances

Snapping

Make theme (layer ) active

Start Editing

Click on snap tool (now you can set snap tolerances interactively on screen)

Click on snap tool

Then click inside map view and drag, it will set the snap tolerance distance (circle)

Now you are ready to go

Roads > Road Grade

Enter desired grade and then click on the Pegger Tool

To start a new road with the Pegging tool, hold down the shift key while clicking on a contour line in the view. Pegging will begin when you click on a single contour line. If Pegger cannot determine which contour is the desired start point then the following information will be displayed:
