DIGITAL ELEVATION MODEL VALIDATION WITH NO GROUND CONTROL: APPLICATION TO THE TOPODATA DEM IN BRAZIL

Digital Elevation Model (DEM) validation is often carried out by comparing thedata with a set of ground control points. However, the quality of a DEM can also beconsidered in terms of shape realism. Beyond visual analysis, it can be verified thatphysical and statistical properties of the terrestrial relief are fulfilled. This approachis applied to an extract of Topodata, a DEM obtained by resampling the SRTMDEM over the Brazilian territory with a geostatistical approach. Several statisticalindicators are computed, and they show that the quality of Topodata in terms ofshape rendering is improved with regards to SRTM

Devenir, former, recruter un géomaticien : Petit guide pratique de la géomatique à destination des employeurs, des candidats et des formateurs

Document pdf disponible sur le site de l'AFIGEOPublié à l'occasion du Colloque national " Métiers et compétences en géomatique : des formations aux emplois " le 14 novembre 2013 au CNAM, ce guide est le fruit d'une réflexion collective menée au sein du Pôle Formation-Recherche de l'AFIGEO. S'appuyant sur de nombreuses ressources (issues des résultats d'une enquête métier réalisée en 2013 avec GeoRezo et le GDR Magis, d'analyse de fiches de poste, de l'observatoire des GeoFormations, de la démarche de reconnaissance des métiers), il s'organise autour de 4 chapitres : - QU'EST-CE QUE LA GEOMATIQUE ? - A QUOI SERT UN GEOMATICIEN ? - SE FORMER A LA GEOMATIQUE ? - RECRUTER UN GEOMATICIEN ? En s'adressant aux étudiants, formateurs, recruteurs, géomaticiens débutants ou plus expérimentés, ce guide vise à apporter un éclairage pédagogique, concret sur le vaste monde de la géomatique, sur les spécificités des compétences, des métiers et des formations associés.

Dengue Spatial and Temporal Patterns, French Guiana, 2001

To study a 2001 dengue fever outbreak in Iracoubo, French Guiana, we recorded the location of all patients’ homes and the date when symptoms were first observed. A geographic information system was used to integrate the patient-related information. The Knox test, a classic space-time analysis technique, was used to detect spatiotemporal clustering. Analysis of the relative-risk (RR) variations when space and time distances vary, highlighted the maximum space and time extent of a dengue transmission focus. The results show that heterogeneity in the RR variations in space and time corresponds to known entomologic and epidemiologic factors, such as the mosquito feeding cycle and host-seeking behavior. This finding demonstrates the relevance and potential of the use of GIS and spatial statistics for elaborating a dengue fever surveillance strategy
