Ian, for Mauritania boundaries, if you dont know already, this link might also be considered : http://cod.humanitarianresponse.info/country-region/mauritania


Due to the present turmoil in Mali, the UN-OCHA staff has identicated as priorities for Mali the integration of populated places and subnational boundaries into OSM.

UN-OCHA Humanitarian Response COD Registry for Mali (http://cod.humanitarianresponse.info/country-region/mali) is providing shp files describing these boundaries.
I already imported boundaries for region and population places for Mali. I also integrated the information into the Mali Interactive Map.

But I am not familiar with the ogr2osm python script, and I would appreciate that somebody volunteers for this task.

Hi, 


We've gotten the green light from data owner[1] to import admin-2 boundaries for Egypt and Mauritania. This data is corroborated by wikipedia [2] and similar to the UNOCHA SALB data [3], with minor discrepancies[4] with the latter. Shapefiles can be found here:

- Mauritania http://maplibrary.org/stacks/Africa/Mauritania/index.php
- Egypt: http://maplibrary.org/stacks/Africa/Egypt/index.php


To convert to .osm we are using ogr2osm with a simple translation function[5]. The only difference between Egypt and Mauritania is the egyptian governates are classified as admin_level=3 whereas mauritania's departments are classified as admin_level=4. this is captured in unique translation functions. 


Once in JOSM, we will delete the national boundaries in our generated .osm file (these appear to be robot-generated and really node-heavy). Ways for each admin boundary will then be connected manually to existing admin-2 osm boundaries, and we'll also manually repair the subnational relations.  


Cross-posting this HOT as I know others are working on imports in the Sahel. Please respond with questions and concerns!


Thanks,
