 Consulting & GIS Project Management Minimize

CGIA brings breadth and depth of experience to a range of projects involving GIS. We help clients define and articulate business requirements and create effective solutions that meet those needs and support informed decisions.

Project Examples
Statewide Seamless Orthos
Client – NC 911 Board and Durham Emergency Communications

CGIA is managing a project to acquire true color orthophotography at 6-inch resolution during the 2010 flying season for all 100 counties in North Carolina. The data will be available for download through NC OneMap. CGIA’s project partners are the NC Floodplain Mapping Program to take advantage of the Qualifications-Based Selection contracts in place for ortho imagery acquisition; the NC Geodetic Survey to assure positional accuracy of the new products; the NC Land Records Management Program; and the Statewide Mapping Advisory Committee’s Working Group for Orthophotography Planning.
  Building A Statewide Master Address Database
Client – NC General Assembly

CGIA, in collaboration with the Office of State Budget & Management, developed a NC Master Address dataset representing a compilation of the best available representation of situs addresses and their location. Cooperating county and municipal governments were the source of the data. In addition to a dataset that will support the upcoming 2010 Census, the outcome included a comprehensive and flexible workflow for ingesting and managing address-related data. The process has been specifically designed to be adaptable for meeting business requirements of state and local agencies. Each person added to the Census’ NC population count represents $10,000 in federal funding for North Carolina over the next decade.

Client – Library of Congress

CGIA manages an on-going project that pairs state government archives staff with geospatial experts in Kentucky, Utah and North Carolina to investigate the issues surrounding the preservation of “at risk” geospatial content. The partners are investigating the policies, process, inventory, technical infrastructure, storage capacity, and funding issues involved in ensuring long-term access to data.
How Do We Improve North Carolina’s Surface Water Maps?
Client – NC General Assembly

CGIA managed a project to create a more accurate map of rivers, streams and other water bodies for 19 counties in western North Carolina. The project leveraged the State’s investments in statewide elevation data (using LiDAR technology) and the digital aerial imagery resources of counties and the state. Local government stakeholders contributed ancillary datasets to refine the placement of hydrographic features.
