GPS data collection – Day 2.
Students will use a GPS device to gather geo-referenced storm sewer
data.
Warm-up activity:
Have students launch AEJEE, add three layers, maximize their AEJEE window, and
make one layer active.
Main activity:
1. Go outside and collect storm drain data with students.
2. When walking to field site area, review cardinal directions
with students.
Have students notice the magnitude changes in latitude and longitude coordinate
positions as they walk.
3. Emphasize accuracy and validation, and writing neatly.
In the field:
• Verify the students' data collection sheet as soon as they take data.
• Review any inaccuracies in data collection on site points.
• Point out any questionable numbers written with low quality handwriting.
• Make sure accuracy is recorded.
• At intersections, ensure that the correct storm sewer location check
box has been marked.
• Ask students at intersections:
1. Are we on the north side or south side of the street?
2. Are we on the east side or west side of the street?
• At intersections, have students point out on the paper map where they
are currently standing.
Materials needed:
GPS
Clipboards
Data collection sheets
Paper map of area
Tape measures
Handout: Data collection sheets
