GPS Decisions
How much accuracy?Resource grade vs. Survey grade2-5 meters vs. sub-meter
At what cost?Survey grade rental - $60 daily or moreResource grade purchase - $150 - $450

Project Plan
Step 1 Pre-map address points in Arcview
Step 2 Improve locations in field & add new points
w/ArcPAD Step 3
Integrate points into address mapping environment
and spatially relate to parcel numbers

Design Considerations
Attempt to account for variations in address styles, road naming, & other anomalies
Build for future 911 database integration
Generate in a format for AS/400 environment
![Page 12: Cost Effective Addressing With ArcPAD 6. Green County, WI Mostly Rural County- Population 34,000 Approximately 24,000 parcels 576 square miles.](https://reader034.fdocuments.net/reader034/viewer/2022051516/56649f215503460f94c39edc/html5/thumbnails/12.jpg)
Final Design
Parsed address format similar 911 database
Confidence point placement rating
Full address label field for mapping needs

Pre-Project Mapping
Used existing hard copy maps and checked against tax roll and “organic” databases in office
Process took approximately 4-5 weeks for 16 towns

In the Field
Hardware- Dell Laptop w/ Power Converter
Parcels, centerlines and County orthophoto used for background information during process
Used TracLog option to map progress

GPS Challenges
Need to acquire data in County Coordinate System
Lack of accessibility to geodetic control point
Complexity of use for project staff

Process
Live viewing in ArcPAD over photo/parcels
Pull in driveway & add data

Address Capture
Add point using GPS

Results
Estimate actual accuracies closer to 2.5 meters or less
Average PDOP was 2.2 or less-as low as 1.4 Very fast – Use ArcPAD/no other software to
configure
