Statewide Orthoimagery Project
Goals: to acquire statewide orthoimagery for the following purposes:
1. Support the 911 Coordinating Council’s GIS Gap Analysis & Data Remediation project.
2. Provide a reference layer for call taking and dispatch positions.
3. Provide a statewide, current, & consistent base map that can base leveraged by other state and local government GIS programs.
4. Economy of scale by conducting one statewide project.

Statewide Orthoimagery Project
Deliverables:
• Web Service – Open Geospatial Consortium’s Web Map Service format, provides streaming of data into various desktop and web-based clients without storing a local copy of the data. Supports desktop software clients such as ArcGIS, AutoCAD, and MapInfo.
• File-based formats:
• GeoTIFF – raw version of the data, slightly compressed, tiled by quarter, quarter, quarter quadrangle
• MrSID – highly compressed version of the data, tiled by USGS 7.5 minute quadrangle
Statewide Orthoimagery Project
Licensed product - allows access to the following:• All state government agencies and regents-level institutions• All county-level governments• All municipal (city) governments• All PSAP’s• All Public School Districts• Any firm doing work on behalf of one of these entities• Additionally, license agreement allows:
- Authorized users to develop and publish publically-available web applications which utilize orthoimagery or web map services, provided the raw imagery is not made available for download;
