Standards and Policies
Standards and policies guide the development, management, and sharing of geospatial data and services. They also serve as a guide for government entities to use when developing proposals and contract agreements.
NITC 3-201 Geospatial Metadata Standards
This standard has been developed specifically to the needs of Nebraska stakeholders while maintaining compliance with the metadata standards from the Federal Geographic Data Committee (FGDC), and the International Standardization Organization (ISO). These standards were originally adopted on September 23, 2005, and have been updated to include changes in ISO data standards endorsed by the FGDC.
NITC 3-202 Land Record Information and Mapping Standards.
The purpose of this standard is to realize the maximum long-term return on and overall utility of the public's investment in the modernization of how Nebraska's land records are maintained and distributed.
NITC 3-203 Elevation Acquisition Using LiDAR Standards
This standard is intended for entities participating in collaborative efforts to acquire airborne LiDAR elevations that may contribute to a comprehensive statewide elevation dataset in Nebraska. The standards are derived from the U.S. Geological Survey (USGS) National Geospatial Program’s (NGP) LiDAR Base Specification Version 1.0 and specify Quality Level 3 acquisition requirements and. This standard emphasizes particular requirements and needs for Nebraska.
NITC 3-204 Imagery Standards
This standard is designed for statewide aerial imagery acquisition efforts that meet ASPRS Level II standards meeting minimum horizontal accuracy requirements for a spatial resolution of 12 inches, preferably flown during the “leaf-off” period for trees. These requirements meet federal standards that are driving the need for greater spatial accuracy requirements of imagery for many statewide applications. For example, the National Emergency Number Association has this requirement to develop and create street centerline and address points.
NITC 3-205 Street Centerline Standards
NITC 3-206 Address Standards
These standards provide requirements necessary for the creation, development, delivery, and maintenance of a statewide Nebraska Street Centerline Database (NSCD) and Nebraska Address Database (NAD). Both standards have a direct correlation to one another. Many applications use street centerline and address point data. These standards will enable the data to be integrated not only with NG 9-1-1 but with existing state road network and address databases, routing services, emergency management, and public safety. Address points furthermore support state agency needs in the contact database, tax assessment and enhancing the state’s enterprise geocoding application databases. The standards are compatible with the National Emergency Number Association (NENA) standards for NG9-1-1 and are backward compatible with enhanced 9-1-1. These standards can be used at the local, state and federal level to ensure interdisciplinary compatibility and interoperability with other databases. These standards integrate with existing standards such as the US Federal Highways, National Emergency Number Association (NENA), U.S. Postal Service (USPS) Addressing Standard, and other NITC related standards.
NebraskaMAP Data and Content Management Policy
The NebraskaMAP.gov web site serves as a gateway to Nebraska’s geospatial data and information. The purpose of the NebraskaMAP Data and Content Management Policy is to clarify responsibilities and encourage cooperation among data stewards to share data through a centralized enterprise-level data-sharing platform for intended users needing access to geospatial data for Nebraska. This policy and procedure statement applies to all public and private geospatial data and information requests that wish to be included through NebraskaMAP.
Other Standards and Policies There are additional information technology-related standards for Nebraska governmental entities. These are located through the Nebraska Information Technology Commission (NITC) Standards and Guidelines web site.
