            <gco:CharacterString>La BD ORTHO® V2 bénéficie d'améliorations par rapport à la première version : - meilleure qualité radiométrique (grâce à différents traitements d'égalisation et de réhaussement) - meilleure qualité géométrique (les canevas photogrammétriques utilisés sont de meilleure qualité que dans la version 1) - meilleure qualité des prises de vues (70% des prises de vues sont réalisées avec des caméras numériques qui assurent un contenu radiométrique plus riche et plus stable). Le produit BD ORTHO® V2 est livrable au format TIFF (Tagged Image File Format) en dalles de 1 km x 1km, ou au format ECW (Enhanced Compressed Wavelet) en dalles de 5 km x 5km. La BD ORTHO® V2 est également diffusée sous échantillonnée : BD ORTHO® 1 m Noir &amp;amp; Blanc BD ORTHO® 5 m couleurs</gco:CharacterString>

                  <gco:CharacterString>Le nombre de clichés nécessaires pour couvrir un département est important, ces clichés présentent des disparités fortes d'ensoleillement, d'apparence colorée, de paysage, de comportement d'objets (carrières, sables, surfaces d'eau, ...) et parfois de saison. Dans l'idéal, l'ortho-image d'un département doit être continue et homogène sans surface saturée conséquente. En pratique, l'aspect radiométrique de la mosaïque est le résultat d'un compromis sur tout le département tenant compte des disparités mentionnées. Pour la couleur, chaque cliché est corrigé des effets internes d'éclairement et de couleurs liés à l'ensoleillement. L'ensemble des clichés est ensuite homogénéisé et la mosaïque est finalement globalement rehaussée en couleur et en dynamique afin d'obtenir un rendu le plus naturel possible. Pour le canal infra-rouge, chaque cliché est corrigé des effets internes d'éclairement et de couleur liés à l'ensoleillement, puis la mosaïque est corrigée globalement afin d'exploiter au mieux le spectre radiométrique d'une façon proche des canaux rouge et vert qui composent avec le canal infra-rouge les images infra-rouge couleur.</gco:CharacterString>
