En respuesta al golpe de estado de 2012 y secesión de facto de la parte norte del país, con grandes problemas de migración forzosa, el Humanitarian OpenStreetMap Team está investigando actividades para mapear Malí.

Para mapeo a más largo plazo y coordinación de la comunidad OSM en Malí, mira la página del WikiProject Mali.

Descarga de datos

Puedes descargar datos actualizados de OSM en Malí en la herramienta de exportación HOT, incluyendo extractos de shapefile. Para obtener datos nuevos, haz click en el boton "Start new run" si es necesario.


Activación en enero 2013 a pedido de UNOCHA-Mali

POIs de servicios básicos

Habrá mas detalles en los próximos días.


Crowdmapping: Áreas prioritarias para mapear

Hemos definido tareas en el Task Manager para coordinar voluntarios HOT que estén mapeando simultáneamente. Cada voluntario puede seleccionar una micro-tarea para editar en Potlatch2, JOSM o editores similares. Cada tarea incluye instrucciones detalladas.


Red de rutas: Re-trazar rutas principales para alinearlas a imágenes Bing

La logística humanitaria para entregar bienes y servicios requiere identificar rápidamente la infraestructura principal.

Para responder a las dos prioridades detalladas a continuación, invitamos a mappers experimentados a contribuir con las rutas importantes que podrían ser usadas por ONGs humanitarias trasladándose desde países vecinos y a través de varias partes de Malí.

Para coordinarse, hay una tabla en la página en inglés. Cada voluntario puede indicar allí el número de ruta en la que está trabajando. No olvides agregar puentes sobre ríos y arroyos. Cuando completes una ruta, confírmalo en la columna "comentarios" de la tabla. También indica porciones de la ruta donde no haya imágenes Bing disponibles.

Al editar, incluye #hotosm Mali [road] source=Bing en el comentario del «changeset».

Tareas pre-activación hechas en 2012

Abril 2012

  • Servidor de imágenes Orbview para trazar varias áreas.

Diciembre 2012

  • Tareas en el «task manager» con imágenes de Bing para varias áreas.

Abril 2012: Ciudades

En 2012 se identificaron estas prioridades. En enero de 2013 se definieron varias tareas en el «Task Manager».

Imagery

Please indicate here any Imagery that can be used to map Mali.

High resolution Bing imagery was first limited to the cities of Timbuktu and Bamako. In june 2012, many other areas start to be added. In many areas (see east of San as example), we see large portions of the territory that correspond to water at low levels of zoom and flooded areas at high level of zooms. Other imageries like Orbview show farmlands in these areas. These flooded areas during rainy season should be remapped. The riverbank and islands should be traced correspondingly to the new Bing highres imagery. Observe farmlands and residential areas showed at high zoom levels. Large proportions of the territory in the Inner Niger Delta around Mopti and along the Niger River are under water during this season.

Orbview 3

1464 OrbView-3 images (mostly 1 m resolution, panchromatic ("pan"), and a few 4 m resolution, multispectral ("ms")) of Mali are available, as TMS.

For JOSM: tms[19]:http://osm.arkemie.org/cgi-bin/tiles/1.0.0/mali/{zoom}/{x}/{y}
For Potlach: http://osm.arkemie.org/cgi-bin/tiles/1.0.0/mali/$z/$x/$y

They were processed at level L1Gst by USGS, and have less than 10% cloud cover. Like for Bing, the usual warning about adjusting the offset with GPS tracks before tracing from imagery applies.

Each scene covers about 200 square kilometers. When there is an overlap, the most recent image goes on top. In case of overlap between pan and ms images, pan images, which have better resolution, go on top. If you wish to access ms images anyway, they are also available in their own layer: replace "mali" with "mali_ms" in the above URLs.

Use source=OrbView-3, USGS, 2003-2007.
