RA556 Spatial Data MethologyFinal Project
Allison Willett, Meredie Sexton &Erik Johnson
Overview
• Project story line• Test parameters• Test procedures• Data and results• Conclusion
Project Description
• We are hired to survey a parcel to help determine the best location for a cabin
• We will go to the client’s land and collect elevation data using the total station
• We will enter the data into ArcMap• We will analyze the data• We will produced beautiful maps• The client will be able to build a cabin in the
perfect spot
Lebanon Hills Regional ParkDakota County, Eagan, MN
Beautiful lakeshore parcel.
Project Parameters
• Elevation (40ft above lake)• Slope (less than 20)• Aspect (NW, W or SW)• Distance from lake (greater than 200ft)• Distance from road (at least 50ft away)
Procedures• Locate high point and set up Total Station• Take 60+ measurements between highest point (top of
hill) and lowest point (lake shore)• Use ArcGIS to create point shape file of Total Station
measurements• Interpolate elevation raster• Create slope and aspect rasters based on elevation raster• Create buffers around lake and road• Use suitability analysis to locate best quality location for
cabin
Setting up the total station.

Conclusions
Conclusions
• We were able to identify an ideal location that met all the parameters set by the client.
• We learned about one way surveying might be used in the real world.
• We have the confidence and new insight to make an educated analysis of any parcel we might plan to buy or build on.
Further Steps
• More data points• Include GPS readings of lake and total station
locations• Analyze lake quality, especially in relation to
possible recreational uses
