Caldwell County GIS Development
Spatial Data and GIS in Western
Caldwell County, known as the "Gateway to the Blue Ridge", is located in Western
North Carolina at the foothills of the Blue Ridge Mountains. The county has a land
area of 474 square miles containing 43,000 property parcels and a population of 75,000
persons. The county is distinguished by its pleasant climate with definite seasonable
changes and dramatic elevation changes. The topography rises from 1000 feet along the
southern edge of the county to greater than one mile at "Grandfather Mountain" on the
county's Northwestern edge. Primary occupations in the county include; furniture and
textile manufacturing and agriculture.
In March of 1990, Caldwell County began implementation of the first phase of an
organizational geographical information system (GIS), by contracting with Westinghouse
Landmark to remap all of the property parcels within the county. Prior to this project,
the county had relied upon 1200 hand drawn tax maps at a variety of scales. Furthermore,
the county had three entire townships on the northern edge of the county that had never
been mapped. The primary goal of the first phase of GIS development was to acquire
accurate property parcel information for 100% of the county in a digital format.
Upon completion of the remapping project, the need for a software program for accessing
this new digital data arose. The Caldwell County GIS Department developed an ArcView
based Public Access Program for county staff and the general public to utilize for
accessing the property parcel information contained within the GIS. Since development,
this application has been deployed in five (5) county departments and on numerous computer
terminals dedicated to public access. Users can access a variety of GIS information, such
as property ownership, municipal boundaries, detailed soil information and aerial
photography with a simple click of the mouse. Daily usage by both staff and customers
has been tremendous, forcing staff to add additional terminals soon after deployment.
GIS Public Access with ArcView
GIS Public Access with Visual Basic
Recently with the addition of new GIS data layers, the Caldwell County GIS Department
began searching for a new GIS Public Access Program. Due to increasing personal computer
usage in the county, staff began working on a Visual Basic public access application.
Staff are now in the final stages of beta testing this application. Within the next few
weeks the county is set to deploy this application on twenty (20) additional terminals
located throughout the organization. Users will have access to additional GIS data layers
including; zoning, appraisal, watershed and election district information. Users will also
have expanded functionality including the ability to move the mouse over features and
have information displayed through the use of pop-up windows.

Internet Based GIS Public Access
Phone (828) 757-1330
Fax (828) 757-1295
In the fall of 1998, Caldwell County will deploy an Internet based GIS access application.
Users of the World-Wide-Web will be able to access numerous GIS data layers from home
and their offices. The Internet GIS Public Access will be a Visual Basics application
utilizing Environmental Systems Research Institutes' MapObjects technology. Users will
be able to access property ownership, detailed soils, zoning information, municipal
limits, watershed, and appraisal information for any parcel of property within the
county. Furthermore, information such as watershed, soils and zoning will have a hyperlink
to additional WWW sites where users can obtain additional information such as county
zoning ordinances and watershed regulations and soil surveys.
