Fall 2009 SO432, GIS
Exercise: Sensor Placement
Update your computer to get
the latest MICRODEM and help file, which should be dated 2008.11.11 or later.
Download the new
data files for Sensor Placement Exercise. (only available from USNA)
In the new help file, look
up "Sensor placement" in the Table of Contents under
Tutorials and labs, GIS.
You will use sensors with
the following characteristics:
Range 500-10,000 meter
Height 30 m above the
Target height 2 m above the
Horizontal field of view:
Vertical field of view:
Open the DEM, and locate the international border.
You can note this as an artefact in the DEM, or overlay the state or
county borders on
Digitize the international
border, with an area shape file. You are creating a small area that covers
the border so that you can determine the effectiveness of your sensor placement.
Place at least 10 sensors to attempt
to cover the border. Insure that you correctly
Set the parameters for each
Consider where you place
each sensor. To do this, you should go to the Coordinates tab of the
option form, and pick Reasonable for "verify graphical selections", and
"Graphical blowup" for the Verify option.
This exercise will be
entirely individual effort, and will be due in class on Monday 16 November.
If not turned in at that time without previous authorization it will have a
grade of 0.
You will turn in:
Word document showing your coverage, and a
printout of the results, for three different arrangements of 5 sensors selected
from your 10.
Include a discussing of:
which part of the area is causing you the most
How hard you think it will
be to get multiple coverage of the border with this sensor density.
Do you think the landcover
categories along the border will impact the ability of the sensors to
work. You have a landcover data set to go with the DEM.
what principles you think you should use to place sensors.
The dBase table with your
sensor locations. This will be the "unfiltered" version, with all 10
locations, with the 10 used indicated in the USE field.
