Hello Gregory

Thank you for your response and insight.

Next week, MSF plans to start a vaccination camp in this area. Hence the urgency.

The last known BING imagery is from 2014. so before the floods.

Esri shows satellite imagery from 2023 . After the floods. 

Unfortunately, Esri's image quality is so low that you often cannot tell the difference between buildings and natural objects, let alone recognise an object as such. I have seen many objects that were mapped as a building but on closer inspection (other clear satellite images. were not a building. but a tree or something similar. 

Most importantly, hamlets or villages are mapped. 

As I write this I realise that it is more important that they are mapped as such, e.g. just by mapping it as  a landuse=residential than the exact number of huts.  After the floods, many temporary shelters may have been built that do not appear on an imagery.

We will do our best.

kind regards.
