INSPIRE Reference: D2.8.II.3_v2.0 TWG-OI <strong>Data</strong> <strong>Specification</strong> on Orthoimagery 2011-06-15 Page 3 [ISO 19135] EN ISO 19135:2007 Geographic information – Procedures for item registration (ISO 19135:2005) [ISO 19138] ISO/TS 19138:2006, Geographic Information – <strong>Data</strong> quality measures [ISO 19139] ISO/TS 19139:2007, Geographic information – Metadata – XML schema implementation [OGC 06-103r3] Implementation <strong>Specification</strong> for Geographic Information - Simple feature access – Part 1: Common Architecture v1.2.0 NOTE This is an updated version of "EN ISO 19125-1:2006, Geographic information – Simple feature access – Part 1: Common architecture". A revision of the EN ISO standard has been proposed. [Regulation 1205/2008/EC] Regulation 1205/2008/EC implementing Directive 2007/2/EC of the European Parliament and of the Council as regards metadata 2.4 Terms and definitions General terms and definitions helpful for understanding the INSPIRE data specification documents are defined in the INSPIRE Glossary 13 . Specifically, for the theme Orthoimagery, the following terms are defined: (1) mosaic Image composed of multiple overlapping or adjoining photographs or images merged together. NOTE A mosaic is often used to present a geometrical and radiometrical continuity. A single mosaic may be made from images taken at different dates and even from different sensors. (2) raster Usually rectangular pattern of parallel scanning lines forming or corresponding to the display on a cathode ray tube. [ISO 19123] NOTE The resulting term “raster data” is often used colloquially in the field of geographic information to identify the whole class of data where the spatial geometry is organized into a, usually rectangular, grid. (3) seamline Line used in the process of mosaicking to delineate the areas of the contributing input images. NOTE 1 These lines usually pass trough areas where radiometric image differences are minimun or alternatively follow natural borders to minimize the observation of borders between images. NOTE 2 Seamlines can be, and often are, defined as polygons (4) tiling Process of cutting out an image into smaller images (tiles). NOTE The resulting tiles usually form a mathematical partition of the original image. A set of tiles may be created from a single image or from a mosaic. 13 The INSPIRE Glossary is available from http://inspireregistry.jrc.ec.europa.eu/registers/GLOSSARY

IR Requirement X Requirements that are reflected in the Implementing Rule on interoperability of spatial data sets and services are shown using this style. DS Requirement X Requirements that are not reflected in the Implementing Rule on interoperability of spatial data sets and services are shown using this style. Recommendation 1 Recommendations are shown using this style. 2.7 Conformance DS Requirement 1 Any dataset claiming conformance with this INSPIRE data specification shall pass the requirements described in the abstract test suite presented in Annex A. 3 <strong>Specification</strong> scopes This data specification does not distinguish different specification scopes, but just considers one general scope. NOTE For more information on specification scopes, see [ISO 19131:2007], clause 8 and Annex D. 4 Identification information NOTE Since the content of this chapter was redundant with the overview description (section 2) and executive summary, it has been decided that this chapter will be removed in v3.0.
