Orthophotography 1998

Orthophotography of the Hauts-de-Seine department carried out in 1998 * * * This orthophotography of the Hauts-de-Seine territory came from a shot made in the summer of 1998. The technical characteristics of this orthophotography are as follows: * Projection: RGF93-CC49/IGN69 * Resolution: 25 cm * Period of shooting: summer 1998 * Format: JPEG **Special observations** This vertical aerial view has been orthorectified, i.e. the distortions related to relief and perspective have been eliminated in order to propose an image superposable to a map. This orthophotography shall be made available in the form of: * 1 km x 1 km georeferenced tiles * “zip” files containing the tile in JPEG format and its associated georeferencing file * the syntax used for the name of tiles: “ORT_AAAA_XXXX_YYYY” uses XY coordinates in RGF93-CC49 according to the Xmin_Ymax standard of the relevant slab * the download of a slab is done by clicking on the slab in the table or in the map and downloading the associated zip file Aerial shooting is also offered in the form of a standardised cartographic service (WMS). The prohibited areas for aerial shooting in the right-of-way of orthophotography have been blurred in accordance with [Order of 27 October 2017](https://www.legifrance.gouv.fr/jo_pdf.do?id=JORFTEXT000035932840) listing these zones throughout France. **Related data** The Hauts-de-Seine Department offers you all of its aerial shots made at different periods (from 1978 to the present day). Orhophotographs (HR: high resolution) produced on these occasions are freely available on the platform. With a very close resolution and high precision, these orthophotplanes form a coherent set allowing comparisons over time.
