Mapweaver

Mapweaver is a Perl based rendering engine that takes a .osm file and generates SVG output. Mapweaver is the successor of Mapgen.pl. Mapgen has evolved too much and became a mess to maintain. So some new concepts were followed when porting mapgen to mapweaver:

• way more modules for better maintenance
• better configuration possibilities (ini file i.e.)
• easier rule file in text format (no more conversions needed)
• extended command line help (all options and are explained and possible attributes of objects listed).
• verbose and debug mode
• no more scaling in rules and command line options. everything is handled on 300dpi basis. less confusing.
• most map elements can now be moved to different locations
• some sizes in rules can scale between fromScale and toScale (minSize:maxSize)

Program is still under development... Looking forward to bug reports and wishes.

Outstanding features

• Fully automatic SVG map creation from OSM files (XML/bz2/pbf)
• Fully automatic download of needed data from overpass servers
• Add elevation data (SRTM) from separate file automatically
• Just call perl mwInteractive.pl if you don't want to bother with data and command line parameters
• Automatic conversion to PNG (different dpi) and PDF
• Automatic extraction of needed data out of OSM file; just specify a place name or node ID
• Way label replacement by numbers if way is too short - incl. legend/key in map (optional)
• Circles and discs around nodes
• Scale objects according to map scale
• Normal grid, coordinate grid, POI and Street Directory (with grid reference; and as PDF)
• Map legend (possibly in separate file)
• Map ruler
• Renders POIs from external POI file
• Renders Shields instead of names/refs if desired
• Label transformation, i.e. to use upper case letters for a given name

Manual and Help

Mapweaver/Manual

There is not yet a complete manual. But most parts of the mapgen manual can be used. For differences see output of command line option -help or here: Mapweaver/Help.

Installation

On Ubuntu/Debian:

1. Make folder:

mkdir mapweaver
cd mapweaver/

2. Checkout subversion repository

svn co https://svn.openstreetmap.org/applications/utils/gary68 ./

3a. install dependencies

sudo apt-get install libcompress-bzip2-perl libgd-graph3d-perl libmath-polygon-perl

3b. if desired, osmosis for OSM related tasks, inkscape for dealing with svg files

sudo apt-get install osmosis inkscape

3c. install Geo::Proj4 and its dependencies:

sudo apt-get install proj libproj-dev libwww-perl libdbi-perl
sudo cpan Geo::Proj4

NOTE: The package proj is not available on recent Debian versions, instead install proj-bin and libproj0. Also, you might try first downloading from http://svn.osgeo.org/metacrs/proj/trunk/proj/src/ the files projects.h and proj_api.h then copy these files with admin privileges to /usr/include/ or /usr/local/include .

3d. latex packages for pdf export

sudo apt-get install texlive-latex-base texlive-binaries ghostscript

4. unpack icons.zip:

unzip -d icons icons.zip

5. create mwconfig.ini and copy the standard rules file into something editable which won't be touched by updates. Alternatively, just create a blank mwconfig.ini and edit the default mwStandardRules.txt itself.

echo "style=yourstyle.txt" > mwconfig.ini
cp mwStandardRules.txt yourstyle.txt

6. launch the program with

perl mw.pl -in=yourfile.osm

Updating

cd mapweaver/
svn update

Files

ini file

# config file 
out=gerhard.svg
scaleset=25000
pdf=1

Rule file

The rule file format completely changed from Mapgen.

Empty lines and lines beginning with "comment" or "#" are allowed.

Some examples are on this page

Icons

Icon sets can be obtained here:

• Mapnik default set
• Icons from Gary68

Wishes / Todos

• Coast line debug
• keep temp file under given name for further use
• random temp file name
• single icon for area
• ps/eps export
• license texts mapweaver, mapgen and dir.pl
• examine textures in PNG
• triangles for connecting page numbers
• declutter stats
• relation analyzer
• tag statistics
• scale patterns of areas
• multi language support (mwDir)
• extract places given by polygons/multipolygons?
• support borders better
• space management for route labels

Recently implemented

• Include elevation data from separate file; -srtm="filename" option added (0.47)
• mwInteractive added; output filename problem fixed (0.46)
• add overpass api access (0.44)
• fixed some errors; prevent errors caused by false OSM data (0.42)
• fixed some errors; draw only items inside drawing area to reduce memory needs for graphics conversion (0.40)
• show GPX files; Prg for directories can now be configured (0.37)
• new space management for labels and icons (0.36)

Mapweaver/Older Versions

Source

• mw*.*
• other needed modules *.pm

If you checkout the svn, you shouldn't need to access the repository.
