Turn on GPS by attaching batteries. Nothing else is needed.
Attach the cable to the
bottom of the Casio.
Then turn it on by
depressing the small “power”
button on the left side.
Click under the windows icon to start SiteMate. Click once on the splash screen. Then click “open scouting” and say “new”
Create a new log file. This will be the record of your session today
Enter your initials as a file name. Brief, no spaces;
Select “Blank template” and click the small round “OK” button.
The new scouting log file opens and asks if you want to add an attribute. You do.
It asks if the attribute will be text or numerical. I suggest text but its not really important today.
Click “OK” again to return to the map view.
Select boundry or points. You will use both at some point.
Then click on “go” to begin.
Our aerial photos were taken when the building next door was under construction.
We need to find the area now planted in grass in front of the new building.
Red line is Nick following the sidewalk.
The big jump towards AGAD never really happened.
That is caused by bounce from nearby buildings and trees.
This software gives you no warning.
Use points for the 3 hydrants and the callbox and boundary for the grass area.
Here Nick is walking around the fireplug, his path is drawn in blue.
At the same time Monica, using another GPS is standing next to the fireplug (drawn as purple dot.) Notice the discrepancy. Nick’s blue line should circle the purple dot. Why are the units not agreeing?
These represent locations
collected by a differential GPS antenna on our roof. In 24 hours the points scatter around a 4.0 meter circle. In Tippecanoe county a second of a degree is about 30 meters.
If you get this window, click “no” to partnership.
When ActiveSynch appears, click on explore to see your stored files. Look in Personal.
