[mkgmap-dev] [PATCH v1] Precompiled sea generator

Wed Jun 20 21:49:24 BST 2012

Hi,

attached is the generator for precompiled sea data.

Additionally you need some geotools libs (they are not downloaded by 
ivy). You can download it from 
http://sourceforge.net/projects/geotools/files/
The required libs are:
commons-pool-1.5.4.jar
gt-api-2.7.5.jar
gt-cql-2.7.5.jar
gt-data-2.7.5.jar
gt-main-2.7.5.jar
gt-metadata-2.7.5.jar
gt-opengis-2.7.5.jar
gt-referencing-2.7.5.jar
gt-shapefile-2.7.5.jar
jsr-275-1.0-beta-2.jar
jts-1.11.jar
vecmath-1.3.2.jar

The generator can be started with
java -cp <mkgmap classes dir> 
uk.me.parabola.mkgmap.sea.optional.PrecompSeaGenerator <shapefilename> 
<projection> <outputdir>

shapefilename: the filename of the .shp file
projection: WGS84 or any EPSG:xxxx
outputdir: the directory to store the precompiled files

The generator is not included in the mkgmap.jar file because the 
geotools libs are not automatically downloaded by ivy. If anyone can 
give an ivy dependency for the libs it is possible to change that.

There are some performance settings that might be changed on your 
computer to better meet the memory/CPU settings of your computer. Have a 
look at the PrecompSeaGenerator constructor. The defined settings are ok 
for 3gb memory (-Xmx3g).
