Map Somalia

Posted by shakasom on 14 September 2014 in English (English).

Somalia is mapped scarcely. As map lover and GIS analyst i have vowed to contribute the openstreetmap in Somalia. We will start one day our Openstreetmap community in Somalia.

Location: Wadajir District, Afgooye District, Lower Shabelle, Somaliland

Apart from the wiki, have a look how things are done in other countries that are more completely mapped. In case of doubt, just post here or on the forum.

You will find that almost all of Somalia’s current OSM data (especially northern part of the country) was uploaded in 2008 with the change comment:

“Mart Roumen; FAO-SWALIM; Madmappers-SOM-2008-01”

The good news is that because of that 2008 upload, Somalia has at least some data, it is not blank. The bad news is that the accuracy is very low. There are many problems, especially with classification, for example, many almost-nonexistent trails (temporary camel tracks?) are marked as highway=primary.

I spent a lot of time to clean up the “Mart Roumen” data in many Somali cities and villages (Borama, Hargeisa, Burao, Laasacanood, Berbera, Galkacyo, others). But of course, it is a very big country and I cannot possibly do it myself. Good luck!

Thanks Christian Ledermann and joost schouppe for the suggestion.

Bdsicoe, It is good to hear you have done so much mapping in Somalia and know alot. Indeed, the data of quality collected by any agency in Somalia is quite low for several reasons. I have worked with the UN and have massive newly collected GIS data especially in Mogadishu but needs licence and takes time. I will try to help out clean the “Mart Roumen; FAO-SWALIM; Madmappers-SOM-2008-01”. Thanks

Hi,

The material was not derived from images but from the 100k’s- scanned maps (from the 70- 90’s)

I’m always willing to help you if you have new collected GIS-data to rebuild the old 2005/2007-package that was published in 2008.

y.s.

Mart

Thanks Mart. Sorry for the late comment, I was travelling with limited Internet connectivity.

We can discuss how we can bring in the new data.

Hi,

It took around 7 months to redraw the old UNDP-package ( that was corrupted). It was done after the Mogadishu-city drawing was build and provided by Madmappers.com. The few older sat-images that were used were not fully geo-corrected and to combine that with 100k-maps gave this result. It was good enough for the purpose to have something to navigate with in a country were ngo’s didn’t had anything suitable at that time. After it was finished and published as a GPS-package by FAO-Swalim it became an issue in OSM. Besides some northern city-drawings it was done by 1 person. :-) . At the moment I’m looking for historical maps in the southern part to update databases with old ppl-names and -locations and clan-locations. If anyone has the 400k- Carta della Somalia (IGMI) as scanned images and is willing to borrow me a copy, I would be very pleased. The original package 100k’s I have combined with Russian 100k’s to fill the blanks in the Canadian/ Brittish coverage in the southern part, so if intressted I can build an updated drawing in those parts.
