                    L'ORTHO IRC est une collection de mosaïques numériques d'orthophotographies en infrarouge couleur rectifiées en projection Lambert 93. Elle est produite par l'IGN. Elle résulte d'une prise de vue aérienne analogiques datant de l'été 2015 orthorectifiée en projection Lambert 93 puis assemblée. Elle couvre l'ensemble les départements du Haut-Rhin, du Bas-Rhin ainsi que l'agglomération de Kehl. La résolution native de l'image (taille du pixel) est de 20cm.
                    Ce projet a bénéficié de financements de la Région Alsace, du Département du Haut-Rhin, du Département du Bas-Rhin, de l'Europe (FEDER) et de l'Etat français (FNADT). Les données sont disponibles en licence ouverte (Etalab).
                    Un flux de consultation sera prochainement mis en place depuis la géoplateforme CIGAL et le format JP2 80 n'est pas encore livré.

                            Ce produit correspond aux spécifications telles que décrites dans le descriptif de contenu de mars 2014 – BD ORTHO® HR et le descriptif de livraison de juin 2014 – BD ORTHO® HR, moyennant les adaptations et précisions techniques de l’annexe de la convention de subventionnement du 10 septembre 2015 (actions 1 et 2 ci-dessous).

                            Action 1 : prise de vues aérienne
                            Emprise géographique : ensemble du territoire de la région Alsace et de la Ville de Kehl avec une zone tampon de 500 mètres sur le territoire français et de 1 kilomètre en dehors.
                            Acquisition d’images numériques couleur d’une résolution native de 20 cm.
                            Dévers maximum sur les bâtiments inférieur à 25%.
                            Angle solaire supérieur ou égal à 40° pour les zones dites en agglomération et 30° sur les autres zones.
                            Réalisation de la prise de vues aérienne entre le 15 mai et le 15 septembre 2015, si les conditions météorologiques le permettent.

                            Action 3 : orthophotographie numérique infra-rouge
                            L’ortho-rectification sera réalisée en utilisant les Modèles Numériques de Terrain disponibles les plus précis.
                            L’orthophoto sera produite en projection Lambert 93 et en Lambert 93 (zone 7) CC48.
                            L’orthophotographie sera livrée en dalles de 1 kilomètre de côté selon les kilomètres ronds de la projection.
                            Les formats des fichiers seront :
                            Jpeg 2000 ;
                            Jpeg 2000 optimisé ;
                            TIFF (Tagged Image File Format) 24 bits "vraies couleurs" RVB, non compressé, non tuilé. Le géoréférencement des dalles ne sera pas intégré dans le fichier image

                            Le découpe tiff et jp2000 e100 est en 1km x 1km, le jp2000 e80 (optimisé) est en 5km x5km.
                            En  mode optimisé, la  compression  JPEG2000  se  fait  au  taux  de  compression  nominal  de 20. Le taux réel de compression est  choisi  pour  qu'aucune  différence  de  colorimétrie  ne  soit  visible  au  zoom  1  (c’est-à -dire  à  l’affichage  optimal  des  données  en  fonction  de  leur  résolution)  entre  l'image non compressée et l'image compressée. La  colorimétrie  est  ainsi  globalement  conservée  avec  en  particulier  l’absence  de  création  de  couleurs parasites, de flou et de perte d’information visible. Cette compression ne dégrade pas la géométrie.
