Step by step directions for PLGR Avenue script

1.  In your ArcView project, open Scripts, then bring the text of the Avenue script into your list
of scripts for the project (4th buttom from the right), and compile it (button with check). Under
Project, re-name the script something that makes sense such as PLGRSCPT.

2.  Under the Project...Customize menu, (Type=View, Category=Buttons), create a new button
that will run the script you have created by hitting the NEW button.  For example, I created a
button with a "P" in it by filling the table at the bottom of the screen:

Click = PLGRSCPT (or whatever you name the script)
Disabled =False
Help=blank
Help Topic=blank
Icon=P
Invisible=False
Tag=blank
Update=blank

3.  Close the script editor, then open the view you wish to have the PLGR data appear in, i.e.
orthophoto or other base map.  (Don't try to run the script from the script editor--it won't work. 
Only run the script from the button you have created). 


4.  When you click on the button you created, a screen will appear allowing you to select the file
of raw PLGR data (it is assumed that you have already captured the data to a text file (with a .txt
file extension), and that the PLGR, before offloading, was set to use the same coordinate type as
your basemap, i.e. UTM or LAT LON).  The script will strip off the extraneous characters by
ignoring every line that doesn't begin with "NP".  A popup screen will show you what, if any
characters, are deleted. 

5.   Another screen will ask you if the data is in UTM format; this allows you to use basemaps or
photos registered in UTMs or LAT LON.  If you say no, the data is assumed to be in Lat/Lon. 
Column headings of the created table, and choice of fields for x-y coordinates are selected this
way.

The script will add the appropriate header to name the table fields, and then bring it into the
current view as a theme, using blue dots for each data point.  Click on the PLGR theme to make
it appear.


A couple of notes: First, don't use the file name PLGRDATA.TXT because the script uses this
name for its converted data.  Second, copy the new theme to a shape file if you wish to run the
script multiple times and /or edit the table.
