After a rather extended period while the commissioning of the satellite; the radiometric and geometric calibration of the imager; and the validation of the operation of the satellite and its pushbroom scanner were carried out, the first set of sample images was released by ORBIMAGE on 18th December, 2003. These comprised high-resolution images of Tokyo, Japan ; Baghdad, Iraq ; and Sacramento, California and Washington, D.C. in the U.S.A. In fact, these are samples of the OrbView BASIC image product that will be offered by ORBIMAGE. Samples of the geo-referenced and rectified OrbView ORTHO image product will be released in January 2004.

High-resolution imaging from space: a world-wide survey (part 1 North America) / Gordon Petrie in Geoinformatics, vol 7 n° 1 (01/01/2004)

Public [article]  inGeoinformatics > vol 7 n° 1 (01/01/2004) . - pp 22 - 27 Titre : High-resolution imaging from space: a world-wide survey (part 1 North America) Type de document : Article/Communication Auteurs : Gordon Petrie, Auteur Année de publication : 2004 Article en page(s) : pp 22 - 27 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Acquisition d'image(s) et de donnée(s) [Termes IGN] Etats-Unis [Termes IGN] Ikonos [Termes IGN] image à très haute résolution [Termes IGN] ORBVIEW [Termes IGN] Quickbird [Termes IGN] satellite militaire Résumé : (Auteur) My two previous overview articles on high-resolution imagery from space were published in the March 2001 and September 2002 issues of Geoinformafics. These were concerned mainly with the commercial providers of such imagery - since the vast majority of the readers of the magazine (and users in general) do not have access to the high-resolution imagery obtained from military reconnaissance satellites. However it has been apparent for some time that the largest consumers of high-resolution space imagery worldwide are those government agencies involved in intelligence gathering and in mapping for military purposes. Within this particular context, the commercial space imagery supplements the imagery gathered by dedicated reconnaissance satellites. At the recent ISPRS Workshop on "High Resolution Mapping from Space" held between 6th and 8th October 2003 at the University of Hannover, I was invited to present an overview on current developments and future trends in imaging and mapping from space covering the high-resolution imagery acquired from both commercial and military satellites. The present article is based on this presentation. Because of its length, the article has been divided into three main parts - concerned with developments in North America, Asia and Europe respectively. For the purposes of this overview, high-resolution imagery has been defined as that having a ground sampled distance (SD) or ground pixel size of 5m or smaller.
