Woohoo! For an interesting place to look, zoom in on a border and see what differences you can find for roads crossing said border. For the main Canadian border crossing north of me I can't see any difference in the roads at all. Thanks Jerry! This is very good stuff, as the OSM maps do look really nice, and probably won't suffer from the very stupid projection issues that the Census TIGER data had. That said, the second I tried it I got a map that wasn't lining up with other data I had. At first I thought this was an issue with the server returning a different geographic region than the one requested, because I've seen the same thing happen with terraserver aerial photos, if trying to view too big a map at particular zoom levels. But rather, it seems to be an issue with how the OSM code tries to restrict our zoom level to those that match OSM levels. Here's an example, using my 1261x1019 map window: http://www.swcp.com/~russo/xastir_osm/bad_view.png This particular view is actually one of my map bookmarks, showing the area where most of the APRS activity is near me. The bookmark sets zoom level to 131 and the center to 35d04.715'N by 106d29.866'W. The image is a screenshot showing the OSM layer with a county-provided road shapefile drawn on top. The orange road running diagonally from center-right to lower-right is the OSM representation of NM state road 337, which is represented in black to its left from the county GIS files. The county one is right --- it shows my Igate (KM5VY-10) in the correct relation to roads. Other roads look wrong, too --- compare the sorta reddish major streets in Albuquerque from OSM to similarly-shaped, but differently-scaled, roads in black from the county shapefile. Zooming in even just a tiny bit, as by selecting just the area inside the map boarder, makes the server return precisely what is asked for and the downloaded map line up very nicely with the county data: http://www.swcp.com/~russo/xastir_osm/good_view.png FWIW, when run with debug level 512, the OSM code prints out: left side is -106.777989 right side is -106.217544 top is 35.263983 bottom is 34.893183 lat center is 35.078583 long center is -106.497767 screen width is 1261 screen height is 1019 map width is 0.560444 map height is 0.370800 scale_y = 131 scale_x = 160 zf = 11.627562 z = 12 in the first (bad) case and left side is -106.715161 right side is -106.280817 top is 35.223122 bottom is 34.934406 lat center is 35.078764 long center is -106.497989 screen width is 1261 screen height is 1019 map width is 0.434344 map height is 0.288717 scale_y = 102 scale_x = 124 zf = 11.995294 z = 12 in the second (good) case. I also note that the code appears to be changing requested zoom levels to match OSM zoom levels. This may or may not be desirable (I was puzzled when I tried to set a custom zoom level to a particular value, and the code repeatedly set it to something else). And now that I say that, I see where the problem must be. I note that when I *tried* to set zoom level to 131 by hand (using the Custom zoom level) it wouldn't do what I asked, but when I chose my map bookmark it did actually go to that zoom level --- perhaps the actual issue is that Xastir is really using my selected bookmarked zoom level despite the OSM code's attempt to restrict to OSM zoom levels. As soon as I try to zoom in by selecting the area inside the border, the code that restricts to OSM levels actually does work, and therefore the map I see after the zoom is done looks good. It just seems to be bookmarks that are busted (because the restriction to specific zoom levels isn't respected). Not sure where to look for that mistake, but it would explain why I'm getting bad OSM maps at my bookmarked view. Rather than try to restrict the allowed zoom levels, it might be better to pull in an image of a nearby OSM level and then rescale it to the requested Xastir zoom level. That's what the terraserver and other .geo code does. Regardless, it's cool that OSM is usable now.

Re: [Xastir] Open Street Map support (read this)
Thanks for the feedback. Help is always appreciated Tom and Curt. I'll try to keep up :-) It will take me a bit to try out the great example you provided, but I'll get started. The OSM code is really just a (simple) modification of the tigermaps code. The slow speed seems to be all related to pulling images from the server. It doesn't appear to me like the images in the cache get re-used if the center point changes. So even minor location changes can cause a new map to be pulled. A far better solution would be to cache OSM tiles (256x256), ala web based maps, but it I opted for the quick fix first... The zoom levels are 'binned' because I could not get the scaling to work otherwise. OSM has 19 fixed levels (less for some rendering such as the one I choose to use here). I had to reverse engineer the scale factor because I could not find it documented at the OSM site. The levels work out to 360/2^(L+8) degrees/ pixel, and tiles (the large image I'm using, http://wiki.openstreetmap.org/wiki/StaticMap are built from the tiles) are 256x256. So I pre-calculated a table of OSM levels to xastir scale factors. The next complication is that the OSM scale factor seems to be related to latitude, so I had to map the scale_x value. To a user this is very confusing at this point because the scale set in xastir is for the Y axis. Hope that helps with the understanding. ...jerry On Wed, Jun 9, 2010 at 1:48 PM, Curt, WE7U curt.w...@gmail.com wrote: On Wed, 9 Jun 2010, Tom Russo wrote: I also note that the code appears to be changing requested zoom levels to match OSM zoom levels.

Ok, this makes sense as to why the standard xastir map caching is used. I assumed [incorrectly] that it was loading tiles, for which the normal xastir caching wouldn't be well suited.

If the current scheme of only allowing zoom levels that match OSM zoom levels (which is certainly workable, if not ideal) is maintained, that adj_to_OSM_levels needs to get called every time a zoom level setting is attempted while OSM maps are selected, and it isn't currently being done in all such cases. -- Tom Russo KM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Tijeras, NM QRPL#1592 K2#398 SOC#236 http://kevan.org/brain.cgi?DDTNM It is better to live on your feet than to die with your knees. -- Mil Millington on running, in Instructions for Living Someone Else's Life ___ Xastir mailing list Xastir@lists.xastir.org http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir ___ Xastir mailing list Xastir@lists.xastir.org http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir

You guys are AMAZING!! I know of no other type of project of this scale that can respond to a problem, an idea and implement a fix not only this rapidly, but this effectively. I thought OSM support would be just a dream to be discussed for awhile and then might happen some day. And here it is. Those of us that can barely tell a compiler from a init string Thank you! This freak'n ROCKS! And it looks great too. On 06/09/2010 12:55 PM, Curt, WE7U wrote: Thanks to Jerry Dunmire, KA6HLD, we now have Open Street Map support in Xastir. Woohoo!

On Wed, Jun 9, 2010 at 3:05 PM, Jerry Dunmire je...@dunmire.org wrote: The OSM code is really just a (simple) modification of the tigermaps code. The slow speed seems to be all related to pulling images from the server. It doesn't appear to me like the images in the cache get re-used if the center point changes. So even minor location changes can cause a new map to be pulled. A far better solution would be to cache OSM tiles (256x256), ala web based maps, but it I opted for the quick fix first... It would be good to cache the map tiles on the local hard drive. Lynn pulls the tiles, and caches them for use on the WinCE mobile devices. I think he stores them for 7 days, or to a maximum amount of space used. The user can over ride these values as desired. I have caching set to never discard, as I want to use the large hard drive on my laptop for offline use. I don't have a mobile data connection, so it makes more sense for me to grab the tiles and keep them on my drive. For limited resources like the Win Mobile devices, it's better to dump old tiles, and download new ones as needed. Speaking of this, when storing the tiles locally, one should keep in mind the folder naming convention. I currently have my OSM tiles being shared by RadioMobile, and APRSISCE/32. There's no need to have multiple copies of the same tiles. If Xastir saves the tiles in the same manner, then there's another shared resource available. Obviously the programs being mentioned run on different platforms, but keeping the same tree structure means that cross platform compatibility is already in place if/when the programs merge or cross to the other platform. I'm pretty sure that RadioMobile works under Wine, so the need is probably already there. Another thing that Lynn does that is interesting, is that he varies the opacity of the OSM map in the background. I prefer my background map to be as bold as possible, but Lynn likes his vary washed out. Here are a couple screenshots that Lynn made of tracking a balloon flight earlier today. http://ldeffenb.dnsalias.net.nyud.net/Tracking/Balloons/WB9SKY-11-2010-06-09%20Burst2.png http://ldeffenb.dnsalias.net.nyud.net/Tracking/Balloons/WB9SKY-11-2010-06-09%20Falling.png You can see that the map in the background is very light. This makes the user data POP right out at you. Looking at Tom's map of Albequerque that he posted earlier brought this to mind. I had a hard time seeing the APRS stations on the map, as everything was jumbled together. Perhaps varying the opacity of the map images is an idea that Xastir can do as well. It is a handy feature.

If you guys are so impressed you should have seen what we here north of the border had to put up with for maps. This is nothing short of stupendous. Buy that man a beer, or 2.

Once the issues are resolved we'll definitely be several steps forward. 'cept for the people not served well by OSM... But the good thing here is that you can grab your box of digital crayons, and colour away... need more roads and more details in your area? Just add them in. The more people and applications that use OSM, the more people there are that might help add to the map. OSM has been working towards a critical mass for quite a while now. Many people in the past have looked at the database, and said There's no data in my area, it's no good to me!. We've been working hard at adding more data, and are currently in the middle of importing huge amounts of government data into Canada to fill in the holes. Because the database is getting filled out, when people look at the OSM project now, it is a little more palatable. Now perhaps instead of just saying It's not good enough!, they might now use it, and possibly be inclined to add data or corrections. Including OSM in Xastir is just going to add that much more visibility to the OSM project, and perhaps find a few more helping hands to add more data. The Haiti earthquake is a marvelous example of crowd sourcing. Before the earthquake, Port Au Prince was just a couple roads. After the earthquake, the whole of the area was mapped within days by people working together. Positions of trapped people were even placed on the map by outsiders who received phone calls from the trapped victims. Rescuers were able to look at the map, and know where to send SAR teams. It was actually an amazing example of worldwide teamwork. Take a look at the videos if you have a chance.
