After a hectic few weeks I managed to catch up a little with my mapping, utilising the data I acquired during some recent trips into the field. I've added a few more streets to Palmyra (not named yet though... need to get hold of a tourist map to start naming them) and also added some streets in Deir Ezzor, tidied up some of the existing roads and added a few roundabouts.
There's still lots of work to do on the existing maps; many of the roads in Syria have central dividers and should therefore be mapped as two one way roads, but I figure given my time constraints it's better to get the roads on the map sooner rather than going for 100% accuracy. I am splitting them at roundabouts and junctions though.
During my travels I'm now using mkgmap to get the maps onto my Garmin. Generally it works well, but there are some major issues on some of the roads, for example the highway between Damascus and Deir Ezzor via Palmyra has some continuity issues with routing. I use Potlatch for my editing which is great for small areas, but it's not very good for making large changes due to the limited zoom out capabilities, so reluctantly I'll have to start using some dedicated software.
I'm having a couple of issues using my Garmin device. First of all, seems that Garmin are now blocking access to their website from Syria, so I can't use the WebUpdate software. Also, I can get my maps into RoadTrip (on my Mac) and have no problem making a route from Damascus to Beirut, but when I do the same thing on the Garmin device it can't calculate the route and gives an error. Think it has something to do with joining two maps.
I've also upgraded some of the cycle paths north of Damascus to tracks since they're accessible by 4x4... so they now show better on the map.
