r3678 and overview map problems
by Gerd Petermann 16 Jul '16

16 Jul '16

Hi all, I got no feedback on the do_not_split_0x4a_polygon.patch which I provided to fix the problems reported by Thomas and Andrzej, see http://gis.19327.n5.nabble.com/How-do-I-transform-the-name-of-all-Ways-tp58… I checked older versions of the source and found out that older versions of the code did contain a special treatment for the 0x4a polygons, I removed those in the overview2 branch and I don't exactly remember why, so I've reverted that part of the change. I have the feeling that the code should be changed somewere else, the tests in PolygonSubdivSizeSplitterFilter.java were introduced by WanMil long before we changed the split algo in MapSplitter. Both sources use diverse hard coded limits, and I have no idea why these are not relevant for 0x4a polygons. I assume that there is a maximum tile size (at least we have it in splitter) so maybe mkgmap should stop with an error message when one tries to create a map with larger tiles? Gerd

Roundabouts causes crashing devices
by Minko 10 Jul '16

10 Jul '16

Hi list, Many users of my Openfietsmap are reporting crashes when approaching roundabouts. Some notice it before they enter the roundabout, others report that the device dies on the roundabout itself. In many cases those roundabouts are with cycle routes, so I have removed the bicycle routes from those roundabouts. Some report this fix works, others still complain of crashing the device. There are also cases without any cycle route involved so I wonder if this happens only with my maps. It happens with recent GPS devices like the Oregon 6xx series, Garmin Edge Touring and 8xx, GPS map 62 and 64. It does not happen with older devices. I cannot find any roundabout in my vicinty to reproduce it so it does not happen all the time with every firmware. The only thing that all those reports have in common is that it happens near a roundabout, the device is dying slowly, turning it back on will make it work again. Did anyone here have seen the same behaviour?

Can mkgmap be used to read back in IMG files?
by Jarno Le Conté 10 Jul '16

10 Jul '16

Hi, I'm wondering if mkgmap can be used the other way around, given an IMG file, extract the road network from it and perform routing operations? Looking at the code it seems to be a full implementation of the IMG filesystem which includes both reading and writing. Is this true? The main thing I want to know: Can I extract the road network (and routing information) from a Garmin IMG file, and use it in an OSM routing engine for example? Kind Regards, Jarno Le Conté

Wrong routing in some closed roundabount
by Alexandre Loss 08 Jul '16

08 Jul '16

Hi guys, We note in our group a strange behavior in some roundabounts that are complete loops. Investigating, we discovered that when the starting and ending points of a roundabout coincides with a rountable node, we are able to route through this roundabout. However, if the starting and ending points of a roundabout don't match a rountable node, we have problem to route through this roundabout. The example bellow shows this clearly when trying to create a route em Mapsource from point A to B: [image: Imagem inline 1] Thank you for your time. Alexandre Loss

incorporating available data sets into osm
by 987654321＠use.startmail.com 07 Jul '16

07 Jul '16

Hi I am new to osm and am not sure if this is the appropriate forum in which to ask this question so if it is not, I would appreciate any direction with respect to the best place to post it. I am working in the Northeastern US. Many streams are missing from the map. I found a site http://www.nj.gov/dep/gis/nhd2002.html that contains a shapefile of streams in NJ. I want to determine if there is a method for bulk upload of such data AND if it would be permitted. I have attached a txt file that accompanies the shp file that says " Data Distribution Agreement I. Description of Data to be Provided.

How do I transform the name of all Ways?
by Alexandre de Menezes 06 Jul '16

06 Jul '16

Hi everyone, I want to do some transformations on the names of all the Ways, is there a standard way to do that? For example, I want to replace all occurrences of "Avenida" for "Av.". I tried adding this to my lines file: |highway=* & name ~ '(?i)avenida\s+.*' { add streettype:movedend='${name|subst:(?i)avenida\s+~>}, Av.'} #| But There was no effect. Thanks in advance, Alexandre
