2000. Issues in Acquiring and Integrating Digital Parcel Mapping For Use in Coastal Management Along the Lake Michigan Coast of Wisconsin

The primary objective of this research is to assess the issues associated with the acquisition and integration of digital parcel mapping generated at the local level of government so that it can be utilized to support decision-making about coastal management at a regional scale. It examines the status of digital parcel mapping along the Lake Michigan coast of Wisconsin and the presents the results of an effort to acquire and integrate digital parcel mapping from local governments for a 1000-meter zone inland from the Lake Michigan shore in Wisconsin. Four key factors were identified related to the acquisition of digital parcel mapping from coastal local governments. These include the number of contact points for data requests, the cost of data acquisition, the time required to receive data after the request is made, and restrictions placed on the use and dissemination of digital data. Nine factors were identified that affect the ability to integrate data for use in analysis and decision-making related to regional-scale issues. Many of these are technical in nature. They include: (1) the media used for the transfer of files; (2) the size of the files received; (3) the extent to which the parcel data are documented, (4) the software format of the digital files; (5) the number of map tiles comprising digital parcel mapping for the coastal study area; (6) the compilation methods used for digital parcel mapping; (7) the coordinate system and datum; (8) the data structure of the digital parcel mapping; and (9) the status of coding digital parcel mapping with parcel identification numbers along with the ability to create a linkage between digital parcels and tax roll data to support thematic mapping of ownership and assessment information. Through August 16, 2000, approximately 2 years after initial data requests, digital parcel mapping has been integrated for 489.7 of 540.1 shoreline miles (91%) of the Lake Michigan coast in Wisconsin. A linkage between tax roll data and digital parcel mapping has been made for 386.6 of 540.1 shoreline miles (72%), allowing some analysis of coastal property ownership and value.
