COLLECTION METADATA FOR NIMA-DOI-10 DIGITAL ORTHORECTIFIED IMAGE 10-METER RESOLUTION

---

Title NIMA-DOI-10, [Digital Orthorectified Image 10-meter resolution].

Short title NIMA-DOI-10.

Responsible party United States. National Imagery and Mapping Agency.

Scope and purpose Digital Orthorectified Imagery, 10-meter resolution, is intended eventually to provide coverage for all world landmasses; as of 2000, it is primarily of the northern hemisphere with limited coverage of the southern hemisphere. The source of data is CIB (Controlled Image Base); initially this seems to have been mainly SPOT satellite images. CIB data are produced from digital images that are compressed and reformatted to conform to the RPF (Raster Product Format) Standard. It may be downloaded from the NIMA public-data Website. See also the webpage for DOI 10.

Content type Images from satellites; digital.

Creation date 2001.

Supported search buckets

Geographic locations

Description Geographic locations and regions described by latitude/longitude coordinates.

Metadata mapping MARC 21 fields 034 d, e, f, g (coded cartographic mathematical data---coordinates) and 255 c (cartographic mathematical data---statement of coordinates)..

Notes Queries against this bucket are evaluated using a Plate Carre projection, i.e., by treating latitude and longitude as Cartesian coordinates. Thus, query regions may not include the North or South Poles. Additionally, non-rectangular query regions may not intersect the +/-180 meridian.

Dates

Description Dates and date ranges.

Metadata mapping MARC 21 fields 008/07-14 (publication date(s)), 045 (time period of content), 260 c (publication, distribution, etc. (imprint)---date of publication, distribution, etc.), and 260 g (publication, distribution, etc. (imprint)---date of manufacture)..

Types

Description Terms drawn from a collection-dependent controlled vocabulary identifying meaning or content.

Metadata mapping The ADL Catalog item types, which are in turn derived from MARC 21 field 655 a (index term---genre/form)..

Formats

Description Terms drawn from a collection-dependent controlled vocabulary identifying form or representation.

Metadata mapping The ADL Catalog item formats..

Assigned terms

Description Subject-related terms from controlled vocabularies. This bucket is a subset of the "Subject-related text" bucket.

Metadata mapping MARC 21 fields 650 (subject added entry---topical term) and 651 (subject added entry---geographic name), and other 6XX (subject access) fields..

Notes Non-alphanumeric characters are treated as word separators.

Subject-related text
