Annual Tax Certification Process
How things were done before collaborative project began:
1 – County Clerks Certify tax units with KDOR/PVD through database
summary & paper map (8 ½ x 11 print out, marked up KDOT maps, etc)
submission
2 – Tabular data was reviewed for completeness & maps were reviewed
then filed away
3 – No statewide spatial representation of tax unit boundaries

2009 – Proof of concept
How can DASC be part of Certification process and process edits
quickly?
Work with KDOR/PVD to develop workflow (shared editing tasks)
Clerks training & Clerks conferences
Initial data compiled from various sources
2010 – Establish 2010 statewide baseline GIS file
Data collection & clean up
Contained thousands of topological errors
Attributes had to be standardized (State codes, as well as tax unit
codes)
Data collected via GIS files or paper maps and verified for
accuracy by Clerks
Clerks continue to Certify database summary & paper map to
KDOR/PVD Tax Unit database
