Initial Phase: Complete
The initial phase of the GeoServer focused on providing access to geodetic control data from the National Geodetic Survey (NGS). The GeoServer includes a subset of the NGS attributes and allow the user to search those attributes. A link to the NGS data sheets is provided for each station. The user is able to download the subset of NGS data maintained by the State Cartographer's Office for use in a GIS or spreadsheet software.
Maintenance Phase: Ongoing
Additional data sets will be added to the GeoServer. A small number of attributes from each data set will be included and when possible, a link to the complete data base will be provided. Downloads may exist but are dependent on the distribution policy of each data contributor.
The concept behind the Arizona GeoServer initiated from a 1996 report titled "Framework for an Arizona Geodetic Control Data Clearing House" created by the Geodetic Control Working Group of the Arizona Geographic Information Council (AGIC) Data Resources Subcommittee. The report found that there is an existing and future need for geodetic control in Arizona and specifically a "lack of efficient, effective, and timely method for finding and/or sharing data."
The proposed solution was to "develop a centralized repository for geodetic control information" and stated that the "legal authority to create such a repository already exists with the State Cartographer's Office (A.R.S. 37-173)".
The goal of the GeoServer is to provide efficient, effective and timely access to coordinate control data. Coordinate control data is defined as a monumented location on the ground for which coordinates have been assigned. This definition includes data such as horizontal and vertical geodetic control and can include Public Land Survey System corners.
The GeoServer provides centralized access to coordinate control data by utilizing Internet mapping technology. The GeoServer provides the ability to discover coordinate control data spatially, limited searching functions and in some instances, the ability to download data. It is not the goal of the GeoServer to maintain or provide complete access to every contributors data base.
