Building Clusters (County Cadastral data)

 Last updated on 6/4/2012 1:48:31 PM.

Overview

The building clusters layer is being developed for use within WFDSS and undergoes continual improvements as county-level data become available. County structures data are derived from cadastral data provided by counties throughout the United States. These efforts are being coordinated through the Federal Geographic Data Committee (FGDC) Cadastral Subcommittee and the Wildland Fire Management RD&A.

Data Input

Building cluster points represent the center of parcels where county assessor records indicate taxable improvements are present. One or more structures and other improvements may exist near these point locations. Alternatively, counties may provide structure points that indicate that taxable improvements are present.

Parcel centroids or structure points were created, based on improvement value and/or other field attributes indicating taxable improvements. The resulting layer was then reprojected to GCS, NAD 83.

Disclaimer

These data are intended for strategic use only and should not be assumed accurate for use beyond this purpose. Limited data processing of the available datasets was completed to prepare data for use and analysis in WFDSS.

Many data were obtained through sharing agreements, with the understanding the data would be used solely used within the WFDSS system.

These data should not be shared with any outside parties.

Data Limitations

Building cluster points approximate the location of one or more structures. Most building cluster points represent the center of parcels where county assessor records indicate taxable improvements are present, but may also represent structure point locations identified by county officials. Locational accuracy of cluster points decreases with large parcel areas.

Caution: Building Clusters points are intended for STRATEGIC USE ONLY. Always verify specific structure location with local knowledge.

Building Clusters GIS Team Contacts

The WFDSS application is "data rich". It requires data which is spatially oriented and graphically displays information to support wildland fire and other natural resource decisions. Due to the type and number of interagency spatial data sets required in April 2009 an interagency GIS Team was formed to provide data support for WFDSS. This Team is responsible for acquiring, consolidating, and validating their agency spatial and tabular data. In addition this team developed and maintained communications among local, regional, and national agency personnel to improve the collection process and provide explicit guidance on data needs. The members of the WFDSS GIS Team are:
