[PATCH] Add a substring filter to the style language.
by Jeffrey C. Ollie 28 Sep '10

28 Sep '10

This can be used to extract substrings from values. If the "name" tag on an object was equal to "abcdef": '${name|substring:2}' => 'cdef' '${name|substring:2:4}' => 'cd' As an example, it can be used to clean up the "ref" element on route relations: type=route & route=road & network=US:I & ref ~ 'I\d+' { apply { set route_network='US:I'; set route_ref='${ref|substring:1}'; } } type=route & route=road & network=US:I & ref ~ 'I \d+' { apply { set route_network='US:I'; set route_ref='${ref|substring:2}'; } } type=route & route=road & network=US:I & ref ~ 'I-\d+' { apply { set route_network='US:I'; set route_ref='${ref|substring:2}'; } } type=route & route=road & network=US:I & ref ~ '\d+' { apply { set route_network='US:I'; set route_ref='${ref}'; } } --- .../mkgmap/osmstyle/actions/SubstringFilter.java | 66 ++++++++++++++++++++ .../mkgmap/osmstyle/actions/ValueBuilder.java | 2 + 2 files changed, 68 insertions(+), 0 deletions(-) create mode 100644 src/uk/me/parabola/mkgmap/osmstyle/actions/SubstringFilter.java diff --git a/src/uk/me/parabola/mkgmap/osmstyle/actions/SubstringFilter.java b/src/uk/me/parabola/mkgmap/osmstyle/actions/SubstringFilter.java new file mode 100644 index 0000000..823d402 --- /dev/null +++ b/src/uk/me/parabola/mkgmap/osmstyle/actions/SubstringFilter.java @@ -0,0 +1,66 @@ +/* + * Copyright (C) 2010 Jeffrey C.

Getting rid of the 'Node in too many areas' warning.
by Scott Crosby 16 Aug '10

16 Aug '10

This patch to the splitter that makes this warning MUCH more rare. With this patch, I can split the entire planet into 17219 areas with max-nodes=50000 resolution=14 without a single 'too many areas' warning among the the first 25 of 68 passes. Without this patch, a max-nodes=500000 split has dozens of such warnings. This patch can also allow larger overlaps at a cost of more passes. The fix works by reordering the list of generated tiles. The trick is that the real limit in the splitter is that a node cannot be in more than 4 distinct areas PER PASS (A limit that remains unchanged with this patch.) If a node occurs in 10 tiles, but no single pass contains more than 4 of those tiles, everything works. If there are still 'too many areas' warnings, they can be handled by reducing --max-areas. Note that my patch depends on some other bug fixes; there are several infinite recursion bugs in the current code that trigger when having the splitter generate such small tiles. Some of these were fixed in the trunk, but not all are. In addition, my fixes/cleanups try harder at getting a good split. Scott

How to create POI detail information
by NopMap 02 Jul '10

02 Jul '10

Hi! I would like to put some detail information with POIs to be shown in the details view for the POI on the device. After searching the list, I gather that it can be done but to be honest I did not understand how to do it and how to control what information is added to the POIs. Can you help me there? bye Nop -- View this message in context: http://gis.638310.n2.nabble.com/How-to-create-POI-detail-information-tp5236… Sent from the Mkgmap Development mailing list archive at Nabble.com.

Splitter changes double quotes to single quotes... and disturbs mkgmap
by Attila Szász 30 Jun '10

30 Jun '10

Hi, I've recently noticed that the splitter will create .osm files with values in single quotes. Is there a strong reason to do so while the original input .osm file has double quotes around values? The problem arose when some .osm "role" keys contained single quotes, such as relation #172045 <http://www.openstreetmap.org/api/0.6/relation/172045> - right before the end of this file there's a value with single quote <member type="node" ref="533796734" role="Addenbrooke's"/> which splitter "converts" to <member type='node' ref='533796734' role='Addenbrooke's'/> making mkgmap to complain about a "bad file" and to stop processing further. Anyone encountered this? Thanks, Attila

contour map error
by Andreas Philipp 30 Jun '10

Hi, When processing contour lines from srtm (cut with splitter in an intermediate step) I receive the following error: SEVERE (MapSplitter): 21000001.osm.gz: Area too small to split at http://... (reduce the density of points, length of lines, etc.) The error occours for version r1652 and head from svn. Kind regards, Andreas Philipp

Commit: r1654: RuleSet: Update usedTags after merging other RuleSet
by svn commit 28 Jun '10

28 Jun '10

Version 1654 was commited by elrond on 2010-06-28 22:40:57 +0100 (Mon, 28 Jun 2010) RuleSet: Update usedTags after merging other RuleSet Issue: If you have a style A that has a base style B, only the main tags from A are considered. This means, that many rules from B are not used. I haven't tracked down exactly why and where it happens, but I assume, that some code cleans up the osm data straight after/while reading it and removes any "useless" tags. To save memory. Anyway, I found a solution: Update the "usedTags" of the RuleSet after merging in the base-RuleSet.

How to name islands (are there transparent polygons?)
by Marko Mäkelä 26 Jun '10

26 Jun '10

Some time ago, I added the following translations to the polygons file in the default style: place=island & name=* [0x53 resolution 18] place=islet & name=* [0x53 resolution 20] Before this addition, islands were not named on the map. The polygon style is documented like this in resources/garmin_feature_list.csv: polygon|0x80|0x53||flats||Flatland One paddler complained to me that the named islands look different (and harder to distinguish from water) than unnamed islands. I believe that the unnamed islands would be "empty background", rendered in the Garmin yellow (or black in night mode). Are there any transparent polygon types that could be used for naming islands? How do paid-for Garmin maps represent islands? Marko

some custom typ styles do not appear in nuvi 1310
by maning sambale 23 Jun '10

23 Jun '10

I have nuvi 1310 for testing and noticed that some custom style and typ icon in my map doesn't appear. For example are these two below: barrier=gate [0x660f resolution 24] highway=traffic_signals [0x180f resolution 23] Even at max zoom it doesn't appear. However, when I tapped on an intersection a balloon pops-out telling there is indeed a traffic_signal and you can see details via the "see more" link. All these icons are visible in roadtrip, mapsource, qlandkarte and in etrex. -- cheers, maning ------------------------------------------------------ "Freedom is still the most radical idea of all" -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ ------------------------------------------------------
