TSM352 Land and Water Mgt Systems
A. Quick Distance Measurement
1. Set up a tripod level in the hallway or out on the band practice field, depending on weather or preference. Use the tilting screws to level the instrument. Make sure the instrument stays level for each reading.
2. Focus the cross hairs and the stadia marks.
3. Walk off 10 paces, mark the spot (masking tape or stake), and use the stadia marks to determine the distance from the instrument.
4. Repeat step 3, starting from the previously marked spot, for a total of 100 paces.
5. Walk back towards the instrument, taking a second reading at each mark, including the mark at 100 paces.
6. Use the data collected to complete the table below. It may be easiest to replicate the table in Excel and do the calculations there.
7. Determine the accuracy of the stadia distance at each mark.
Accuracy = Abs(Forward measurement – Reverse measurement)/Average measurement
8. Determine the length of your average pace.
Paces / Forward / Reverse / Avg. Dist. (ft)Upper (ft) / Lower (ft) / Diff.
(ft) / Dist. (ft) / Upper (ft) / Lower (ft) / Diff. (ft) / Dist. (ft)

Laboratory Exercise:
1. Navigate to http://www.rmms.illinois.edu/.
2. Select “Help” from the Hyperlinked menus.
3. Select RMMS tutorial exercise 2 – Soil Data (PDF).
4. Work through the first tutorial step by step.
5. You will calculate the areas of each soil MUSYM
6. You will locate yield data for each soil MUSYM
7. You organize this data in a table and present it as a map utilizing the “text tool” and the “print map tool”.
8. This table will show yield data for Oats, Soybeans, Wheat, and Corn for each soil MUSYM and give the total for the field in each crop.
9. Make sure the text very legible and aesthetically presented.
10. Include the legend.
11. Give your map a distinctive title.
12. Don’t forget your name.
13. Turn in your map by the end of the lab.
