am just back from the UNOGA - Potentiel 3.0 mission with Fred and
others in the mountain valley around Despagne, Grand'Anse. People in
this 1,000 meter altitude valley are spread in the various hills and
live for subistance agriculture. Walking in the valley, we saw
destructed houses everywhere. People are still waiting for substantial
help 4 months after the hurricane. Nights are very cold and humid.
Houses, tools, livestock, plants and seeds were lost. While the majority
of houses are destructed, we saw very few reconstuction or roof
repairs. So far, NGO's have concentrated their efforts in the more
accessible areas along the National road. <br id="yui_3_16_0_ym19_1_1487774768871_30190"><div dir="ltr" id="yui_3_16_0_ym19_1_1487774768871_30191"><br id="yui_3_16_0_ym19_1_1487774768871_30192"></div><div dir="ltr" id="yui_3_16_0_ym19_1_1487774768871_30193">We visited many families in the valley. <span id="yui_3_16_0_ym19_1_1487774768871_30194" lang="en"><span id="yui_3_16_0_ym19_1_1487774768871_30195">They used debris from the hurricane to build temporary shelters next to their destroyed stone houses.</span> <span id="yui_3_16_0_ym19_1_1487774768871_30196">Their situation is very precarious.</span> <span id="yui_3_16_0_ym19_1_1487774768871_30197">Many health problems are reported and no permanent health clinic in the valley except a 1 day/month clinic.</span> <span id="yui_3_16_0_ym19_1_1487774768871_30198">It takes three hours by truck to go to the clinic in Leon.

If you want to use OSM in a particular area with low internet access perhaps you could arrange with someone to run an eye over the area first?

I think a recent one I looked at the bottom 25% of the project had no mapable imagery from Bing or other sources. Other African projects have instructions that do not follow the African highway wiki.

Perhaps as part of the project plan check list the project managers should be asked what plans do they have to ensure that 50% of new mappers work will be validated within 48 hours or whatever the magic window Martin's work shows and that does not include asking me to validate yet another project.

For the most part we are talking volunteers so persuasion works best, having said that something very interesting is taking place in Lusaka. I'm fairly certain from the mapping being done that although the mappers are new to OSM they do know GIS and the quality of mapping is very high. Project 2543 is an example. There has also been some work counting buildings etc using R and the local level of government seem to be involved.<br clear="none"></div><div class="yiv9420870637gmail_default" style="font-family:verdana, sans-serif;font-size:small;" id="yui_3_16_0_ym19_1_1487774768871_29979"><br clear="none"></div><div class="yiv9420870637gmail_default" style="font-family:verdana, sans-serif;font-size:small;" id="yui_3_16_0_ym19_1_1487774768871_29980">Cheerio John<br clear="none"></div></div><br></div></div></div> </div> </div> </div></div></body></html>
