Adding villages / isolated buildings in Mali

This job has pre-located task squares, positioned over Mali using an experimental Crowdsource Imagery application where we present a very simple "micro task". This way, people click on Bing satellite imagery where they could see a village (Try the Kuona Crowdsourcing Application!) . The resulting data is sometimes wrong. Evaluate if there is really something to trace. If not, simply indicate the task square is complete and move on.

For each village which was detected in the micro-task, a task tile was added to this Job. Zoom in to see the tiles to select for mapping.

Cartographier les infrastructures.

Nous testons une approche expérimentale où "La foule" (Crowdsourcing) contribue à détecter sur les images satellite la localiation des villages. Vous devez évaluer s'il y a bien quelque chose à cartographier à cet endroit. Sinon, vous devez simplement indiquer la micro-tâche comme complétée et passer à la suivante.

L'analyse de l'imagerie satellite Bing (approche Crowdsource image) nous a permis dans un premier temps de repérer les villages.

Pour chaque village identifié, une tuile/micro-tâche est ajoutée dans cette tâche. Zoomez pour voir les tuiles et sélectionner une micro-tâche.

Instructions in english

This task is to map residential areas, or isolated farm buildings. If you find a missing village, draw a landuse=residential closed way around it, and add a place=village tag. If there is only an isolated farm building, draw a building=yes closed way. There is no need to map anything else for this task before marking it as done. Roads, rivers, and lakes are a bonus.

You do not need to trace all the buildings in the vilages you map, just the village outline. When there are just one or two isolated buildings though, then it is better to just map them individually and omit the landuse polygon entirely.

Bing Imagery

Zoom-in to the maximum to trace more precisely.

GPX file of Crowdsource detection

You can load this File of results from the Crowdsource Image tool in JOSM as an aid in finding the things to trace. Note that there may be more objects in each task tile than are indicated in the gpx file.

Instructions en français

Il est demandé de cartographier les routes, cours d'eau et polygones zones résidentielles (landuse=residential).

Imagerie Bing

Faire un Zoom au maximum pour tracer plus précisément.

Detection approche "Crowdsource" : Fichier GPX

Vous pouvez télécharger ce Fichier GPX de résultats de l'outil de détection Crowdsource dans JOSM comme aide d'identification des objets à tracer. Notez qu'il peux y avoir plus d'objets à tracer dans cette micro-tâche que ce qui est indiqué dans ce fichier gpx.
