Map Updates 21. April 2011

First of all some OSM related news. I think most of you have noticed it already, if you login into Openstreetmap you now first have to decline or accept the CT and ODBL license. Notice if you are somehow unsatisfied with the switch you can decline now, and still accept later.

For all German speakers, there is a nice post by Jochen Topf who declined the odbl/CT  laying out his reasons (note Jochen Topf works for Geofabrik, that is in general very Pro odbl, and has for example written the first book about OSM (cannot remember the title right now):

 

I completly share his point of view, and hope that many people click on the decline button. If there is a sufficiently big group, the license change can be stopped. For me there is simply no need at all to switch the license and work with all the trouble it causes.

 

As for the maps, I worked nearly 20 hours on improving certain details of the map, here is a non complete list of changes.

Remove uphill scale on resolution 22. Add route=foot & distance>12 rule. Add communication towers bigger >100m to resolution 21. (this is because I prefer to see downhill arrows, so please not only indicate mtb:scale:uphill, but also add incline).

Make sure that tracktype=grade1 does not influence display of highway=unclassified

Move railway=rail & usage=main to resolution 19, cause sucker seem to deem main is everythin. Need better key for this in future.

Lots of work on displaying railways better (get rid of proposed/planned and rework all railways with tunnels, plus lower resolution a bit cause no real high priority lines can be extracted from OSM)

 

 

Map Updates 15. April 2011

First of all I started reworking the contourlines a bit. So for a start now the contourlines can be downloaded as .exe for direct installation, or as used to as .zip. In order so that no probs arise, I chose the map id for the contourlines map to be the actual mapnumber (the first 4 digits of the *.img) plus 300. This way there should be no overlap with other installed maps on the same map ID. I might for next week also offer readymade gmapsupp.img of the contourlines (of course those are only useful for newer type GPS like Dakota, Oregon, edge 800, 62 series, Colorado, .... that accept several differently named "gmapsupp.img" files).

As for mkgmap development, this week a bug got discovered that might have been responsible for very big maps (like joining France and Germany) to crash Mapsource / not show correctly on GPS (basically in all cases the mdr index grew over 128MB, but also some other random probs like gmapsupp.img over 512MB produced by mkgmap were faulty). So if you use the mkgmap creation batches and had any probs, get the newest mkgmap.jar as some bugs got corrected during the last week. Also the Multipolygoncutting got corrected a bit, so less errors wheen zooming far out.

 

As for the maps since the last update: I added abutters treatment like source:maxspeed=urban for urban/rural differentiation. Some stuff to not draw some pipelines under the earth that miss the tunnel attribute and some more minor changes.
