東です。 HOTより西アフリカのマリ共和国 http://ja.wikipedia.org/wiki/%E3%83%9E%E3%83%AA%E5%85%B1%E5%92%8C%E5%9B%BD のマッピングが呼びかけられています。
私も詳細はよく分かりませんが、ニジェール川沿いの季節的な洪水や政治的な混乱で住民の移動が激しい地域とのこと。 これまでもアームチェアマッピングが行われていたのですが先日のBing画像の大幅追加により、 より詳細なマッピングができるようになったようです。 即座の緊急性がある訳では無さそうですが、興味とお時間のある方がおられましたらお試しください。 範囲がかなり広いので、洪水エリアの描き方で悩むより、まずはlanduse=residential でくくったり、道路を描くくらいでも良いかもしれません。 ---------- Forwarded message ---------- From: Pierre Béland <[email protected]> Date: Wed, 27 Jun 2012 23:12:40 +0100 (BST) Subject: [HOT] Mapping Gao, northern region of Mali To: HOT Openstreetmap <[email protected]> The northern region of Mali needs your attention. A vast region in the upper Niger delta and along the Niger river is affected by seasonal floods covering a vast territory. Many isolated hamlets are to be found in this area. Also, the present political turmoil may cause important people displacements. Some people have already started to map along the Niger river in the last few months. New high resolution imagery recently delivered by Bing offers new possibilities to map, more particularly along the Niger river. We find a large imagery band from Timbuctu down to the Niger border. Today, I added to the Task manager the job for Gao : http://tasks.hotosm.org/job/43 I invite people to select some task grids to trace both in Gao city and the nearby islands where we find many isolated hamlets. To facilitate mapping with JOSM, a Preset file is provided. You can download this file from the Workflow area of Task Manager job 43.
