The Parcels Puzzle

The Parcels Puzzle… Cadastral Data: the puzzle pieces from counties fit together quite well. Geometry as is!
5
Three adjacent counties • GIS Query: select parcels that are larger than 10
acres • County A: CACRES DACRES • County B: ACRES • County C: DEEDED_ACR
• Three different queries • Research on field definitions
TOTAL_ACRE
Master Schema • OWNNAME -The full parcel owner name • MAILADD -The full mailing address (single string)
• SITEADD -The full site address • PARNO - A unique identifier used for the parcel • IMPROVVAL -Value of improvements • LANDVAL - Value of land • PARVAL - Total value of improvements and land • PARUSEDESC- Primary parcel use description • GISACRE - Parcel calculated land area

Project Outcomes
10
Delivered • Master schema • Geospatial database
• Online Parcel Transformer • Standardized data • 25 counties • Eastern Band of Cherokee Indians
• EPA Exchange Network REST services • NC OneMap REST services / downloadable data • NCID authentication • User guides
11
Standardized Parcel Data
12
Process: Develop and Update Translations • First time • Upload the source parcel shapefile • Crosswalk from source to master schema • Create the “Transforms” • Run the job • Second time • Upload new source shapefile
• Run the job / correct errors if any
(e.g., new field, new field name)
