Hydrologic analysis : Data created : With PostFlight Terra 3D software, data generated are : DEM (Digital Elevation Model) of 10 cm (depending on quality of flights) Mosaic of 4 cm per pixel or more (depending on altitude of flights From DEM we can extract with ArcGIS : Slopes, TIN (Triangular Irregular Networks), watershed, contour lines, hillshade model, DEM 3D model, …

    1. 1. OPEN DATAOPEN STREET MAP HAITIContextWith OSM, we can talk about open data in Haiti and sharing informationsIn this puzzle, everyone has a piece of land with no real sharing of informationthat makes analysis incomplete and making difficult decisions.So we will offer you about the Open Street Map platform which is used on Haiti,Saint Marc on the North and North-east of Haiti and soon on the otherdepartments.

    2. 2. Tags/attributsLes données attributaires OSM sont stockées sous forme d’une paire associant une clé (key) à des valeurs (values).Le système de tagging est complètement flexible, permettant de créer des clés et de nouvelles valeurs ad hoc selon les besoins.Il est néanmoins recommandé de s’appuyer quand c’est possible sur les tags déjà existants pour assurer une compatibilité de la donnéeOSM.Le détail du système de tags OSM (clés/ valeurs) est accessible sur le wiki à cette adresse :http://wiki.openstreetmap.org/wiki/Map_FeaturesOPEN DATAOPEN STREET MAP HAITISIGHA_2013
