MDR 9 & 10 groups
by Ticker Berkin 17 Apr '19

17 Apr '19

Hi While trying to diagnose a indexing problem, I find that a bit code in imgfmt/app/mdr/MdrUtils.java:getGroupForPoi() troublesome: ... * 4-5 Recreation / Entertainment / Attractions * 6 Shopping * 7 Auto Services * 8 Community * 9 ? * */ public static int getGroupForPoi(int fullType) { // We group pois based on their type. This may not be the final thoughts on this. int type = getTypeFromFullType(fullType); int group = 0; if (fullType <= 0xf) group = 1; else if (type >= 0x2a && type <= 0x30) { group = type - 0x28; } else if (type == 0x28) { group = 9; ... type 0x28 is, according to my device, "Island", but not the one that is findable under Geographic Points/Water Features, as used by the default style, which is 0x650c. So, the first question is, does anyone know why 0x28 was given it's own group. The second problem is that the code that builds up the group start indexes into Mdr10 for Mdr9 assumes that the type ranges of the POI allocated for a group are in the same order as the groups, so, if you actually have a POI of type 0x28 then, because it has a lower type but a higher group than the 0x2a..30 range/groups, mdr9 is wrong. Unless there is a good reason to have 0x28=group 9, then the simplest fix is just to remove the lines of code and put in a comment that the types must be in order. I'm trying to fix something else in this area so I can include this in some future patch. Regards Ticker

mdr5 when no streets (mdr20)

Hi Another problem discovered when investigating indexes. If you have a map with cities but no streets, MDR5 sets the flag that indicates MDR20 indexes are present, and writes an erroneous byte after each record. Attached patch fixes and adds some more flag documentation. Regards Ticker

mkgmap:line2poitype
by lig fietser 09 Apr '19

09 Apr '19

Hi, I'm trying to exclude pois of ways that are connected to each other like this: s1--way1--e1 s2--way2--e2 With s1=start node of way1 and e1 = end node s2 is the same node as e1. In the points file I like to render only points s1 and e2 but not e1 / s2 I have tried these two rules but they will render respectively s2 and e1 too: mkgmap:line2poitype=start & mkgmap:line2poitype!=end & (bridge=* | tunnel=*) [0x2819 resolution 24] mkgmap:line2poitype=end & mkgmap:line2poitype!=start & (bridge=* | tunnel=*) [0x2819 resolution 24] My goal is to render a poi only at the beginning and end of a bridge/tunnel, that consists of many way segments. How can I exclude those in between start and end points?

Commit r4285: add tag mkgmap:way-length for each POI generated from a line when option --add-pois-to-lines is used. It gives the way length rounded to meters.

length() and mkgmap:line2poitype
by lig fietser 07 Apr '19

07 Apr '19

Hi, I'd like to add specific pois for restricted access on bridges and tunnels with mkgmap:line2poitype, but not all bridges are as important, only the longer ones. This is working: mkgmap:line2poitype=start & (bridge=* | tunnel=*) & (bicycle:conditional=* | access:conditional=* | vehicle:conditional=*) { name 'bicycle=${bicycle:conditional}' | 'access=${access:conditional}'| 'vehicle=${vehicle:conditional}'} [0x2809 resolution 24] However, it is not possible to add the length() operator into the points style file, because I don't want small short bridges. I know I can use the lines style file, but adding a custom line tag like restricted_access_on_bridges=yes and use this in the points style does not seem to work. I know I can add this line to the map and render it, but I prefer a point symbol, not another line on a already huge pile of lines on top of each other. Is this because points are processed before lines? Is there another trick I can use?

Curious behaviour of map text
by Manfred Haiduk 29 Mar '19

29 Mar '19

Hi all i'm experimenting with housenumber display in my maps. To do this, i added in my point style file this statement : addr:housenumber=* { set name='${addr:housenumber}' } [0x1e04 resolution 24 ] But if i do this, all other text is vanished, i.e street names, village names etc, only housenumbers are displayed both in map source and on my device. Any idea whats going wrong ? regards Manfred
