Standardized Attributes – Points Too

API Based on Open Standards for Interoperability…

Standardized Attributes - Filters

Lets applications ‘Filter’ NC Parcels (‘Show me Parcels LessThan $50,000 in Value’) - possible because data is in standard model

Standardized Attributes - Filters

Lets NC Parcels begin to answer key business and community questions

Do it Once! A one to one transform:landval
