Looking Back
Why did we need Change?
• Properties & County Changing without proper planning
• Properties could split up to 5-1Acre tracts in 6 years without Plan Commission Approval
• Many “Rural Subdivisions” being created without being intended and putting pressures on the local ag community.
How will the County look with the existing plan?

How has County changed since 1970?
• What resources do we have from that era?• Scanned 1964,1973 & 1982 Aerial photographs
from Surveyors Office• Assessor’s Office created Landuse layer from 1973
photographs.• Compared number of home sites as addresses 1973
vs. 2008
Historical Photos
• Georeferenced 1973 Aerials using 911 road centerlines & USPLS Sections
• Intern Scanned 1964, 1973, & 1982 aerial photographs with Oce TDS 400 Scanner at 400dpi
• Over 250 images scanned
• Add image to Map• Changed Transparency• Zoom to Sections of Aerial• Use Georeference Tools (Rotate, Shift, Scale)• When Selecting Points Use Window Magnifier• Add Control Points
