![]() Aucune base de données ne disposait du positionnement numérique des ports. Les ports fluviaux correspondent à des noeuds des [axe_hydro]. Ils ont été positionnés par comparaison entre le fichier des localités transmis par la MONUC et, soit la carte des ports transmis par la RVF, soit le listing des ports transmis par la SNCC. En l’absence de ville ou de village portant le nom du port, le noeud a été créé en référence au PK transmis par la SNCC ou la RVF. Le positionnement des ports fluviaux a été fait au sein de l’agence UNJLC de Kinshasa en 2006. No database gives a numerical position of ports. The fluvial ports correspond to nodes on the hydrologic axes. They are positioned by comparisons between the local data...
![]() This dataset depicts forest fragmentation in central Africa by roads. This dataset includes roads. This study, or Pilot Analysis of Global Ecosystems (PAGE), examines forest ecosystems of the world using a large collection of spatial and temporal data. This study analyzes datasets at the global, national, and subnational levels, and draws on published and unpublished scientific studies. It develops selected indicators that describe the condition of the world's forests, where condition is defined as the current and future capacity of forests to provide the full range of goods and services that humans need and consume.
![]() Le fichier a été généré par agrégation des districts. This dataset is made by aggregated the districts into Provinces.

![]() Le fichier localités de départ est issu de la comparaison de deux bases (PC_Places et GNS). L’identifiant permettant un lien avec les bases origine a été conservé. Les doublons ont été supprimés et seuls deux noms sont proposés (on pouvait avoir a l’origine jusqu’à 6 noms et donc 6 objets différents pour une même localité). Des relevés GPS ainsi que des numérisation sur images satellites ont été réalisés dans différentes portions du territoire afin de compléter le fichier initial. De nouvelles localités sont donc constamment ajoutées à la base. This dataset represents localities from a comparison of two databases (PC_Places and GNS). The identifiers from the original data base are conserved. Repeats were conjugated...
![]() The Global Human Influence Index Dataset of the Last of the Wild Project, Version 2, 2005 (LWP-2) is a global dataset of 1-kilometer grid cells, created from nine global data layers covering human population pressure (population density), human land use and infrastructure (built-up areas, nighttime lights, land use/land cover), and human access (coastlines, roads, railroads, navigable rivers). The dataset is produced by the Wildlife Conservation Society (WCS) and the Columbia University Center for International Earth Science Information Network (CIESIN). The Human Influence Index (HII) is a measure of direct human influence on terrestrial ecosystems using the best available data sets on human settlement (population...
