Titre: Close Range Photogrammetry Using Dense Epipolar Matching (DEM) Auteur(s): ZEROUAL, IBRAHIM Résumé: This paper deals with the close numerical photogrammetry applications using several testing objects. The different steps of the metrological process are recalled and discussed according to the obtained results. To get effective geometrical information on objects, automation by stereo matching is needed for profit ability and homogeneity requirements. The qualitative and quantitative evaluation of the 3D accuracy of measurements and the analysis of the resulting dot cloud is done according to a known reference. This study proposes restitution for metrological requirements using the method of dense epipolar matching. Mappings quite redundant and distributed on the images, but also a denser reconstruction are preferable for the application of the surface reconstruction. The use of a digital reflex body CANON EOS 5D with focal of 20 and 28 mm enabled us to observe concretely the influence of the measurements accurately and the step to be planned for a metrology project.

Titre: Présence d'une construction récifale corallienne à Djebel Chott (Dahra occidentale, Algérie) : Témoin du maximum transgressif du Miocène moyen en Méditerranée Auteur(s): BOUHAMEUR, MANSOUR Résumé: Abstract A coral reef buildup in the Djebel Chott (Western Dahra, Algeria) : a witness of the Middle Miocene maximum transgression in the Mediterranean. Coral reef buildup with Tarbellastraea anomala Mtchelotti, 1871 and Platycoenia turonensis Michelin, 1847, of Middle Miocene age, occur in a sandyconglomeratic sequence on the substratum of the Oued Chelif mouth (Djebel Chott, Dahra, Algeria). The age of the reefs range from Langhian to Serravallian, with Praeorbulina glomerosa (Blow), 1956 (upper part of Blow N8 zone) and Globigerina nepenthes Todd, 1957 (N14 Blow zone), at the top. The reefal sequences are a witness of the Middle Miocene maxi¬ mum transgression event of the western Mediterranean.
