ACCEPTABLE USE POLICY
2002 Delaware Digital Orthophotography

Delaware's 2002 Digital Orthophotography has been made publicly available on-line and via publication in a simplified version (1-meter pixel resolution) to reduce potential security risks.

This Acceptable Use Policy governs access to the full-resolution version (0.25-meter pixels) of the 2002 orthophotography. Applicants that agree to abide by the policies and restrictions outlined in this document may be granted use of the full resolution data set, subject to periodic review by the Delaware Spatial Data Implementation Team (I-Team).

By downloading, completing, signing and returning the Acceptable Use Agreement (PDF) to the I-Team, applicants agree to abide by the policies and restrictions outlined in this document. Signed Agreements should be mailed to:

The Delaware Spatial Data Implementation Team
C/O The Delaware Office of State Planning Coordination
122 William Penn Street, Suite 302
Haslet Building, Third Floor
Dover, DE, 19901
Phone: (302) 739-3090
Fax: (302) 739-6958

The signed Agreements will be filed in the Office of the Secretary of the Delaware Department of Safety and Homeland Security.

Given the challenges of distributing what is a very large data set, applicants should expect some delay in getting access to the data. For those seeking whole counties or the entire state, a portable hard-drive should be used. Data covering small areas may be available on CD or DVD.

Applicants should consult the orthophotography tile index (available as a PDF map or as downloadable spatial data) to determine which tiles of ortho data they will need.

General Statement of Policy
As a general policy, the 1-meter pixel resolution version of the 2002 Delaware False-Color Infrared Digital Orthophotography shall always be used when practical and appropriate to the situation and need.

Acceptable Uses for the 0.25-Meter Resolution Data
The following are acceptable uses for the full resolution data set.

1. As a digital input or background image for general geospatial research and analysis activities.
2. As a digital input or background image for in-house geospatial data creation processes, including but not limited to:
   a. Heads-up digitizing
   b. Geospatial image analysis
   c. Raster-to-vector data extraction
   d. Data development, maintenance and editing
3. As a background image for printed maps intended for internal image-display and discussion purposes.
4. As backgrounds for, or web-map components of, intranet web mapping systems and applications used only within a secure network. Such web-maps shall not be made available to the public except in accordance with applicable law.
5. As a background image for public meeting display materials that will be withdrawn from public access immediately following the public meeting. Such display materials shall remain under the control of the applicant and shall not be removed from the public meeting site except by the applicant. Where possible, and appropriate, use of the 1-meter pixel version shall be preferred for public display. The 0.25 Meter Resolution data shall only be used for public display when use of the 1-meter pixel version is not possible.
6. As a one-time print-out of an aerial photograph of a constituent or client's owned property, provided that the applicant determines clear ownership and subject to reasonable caution relating to potential security concerns of neighboring properties. Such determinations shall be the responsibility of the applicant.
7. Other uses, similar in nature, that shall be reviewed and approved by the Delaware Spatial Data Implementation Team (I-Team), in partnership with the Department of Safety and Homeland Security, as necessary.

Uses for Which the 1-Meter Pixel Version Shall be Substituted
The following are uses for which the 1-meter resolution version of the data should be substituted.

1. For images published for public distribution as print materials, including maps, photo maps, aerial photos, posters, brochures, etc.
2. For images published for public distribution within all forms of electronic publishing, including but not limited to the use of document formats (DOC, HTML, PDF, etc.) graphic formats (GIF, TIFF, JPEG, etc.) or GIS raster formats (GeoTIFF, MrSID, etc.).
3. For images used as backgrounds for, or web-map components of, publicly available on-line web mapping systems and applications.
4. For images used in all other similar public presentation, viewing, or distribution.

Data Sharing
Any sale, distribution, redistribution, loan, data sharing, or offering for use of the full resolution data set or any derivative at sub-meter resolution outside of the offices of approved applicants is prohibited. The 1-meter resolution data set may be freely shared, but shall not be re-sold.
