[OSM-dev] A few coastline related questions

[Preet]

Hiya,

I'm trying to extract coastline data from OSM... specifically, I want
shapefiles exactly like the ones that are available (processed_p and
shoreline_300), but
* in wgs84 (no projection to mercator)
* without splitting up of polys into tiles

I'm not using the data with Mapnik or to draw it onto tiles -- instead
I'm converting the shapefiles into a mesh
(http://i.imgur.com/vuYmc.png).

So I have a few related questions...
Are there any tools I can use to merge the tiles into more reasonable
polys? Something along the lines of the data available from
NaturalEarthData?

If not, I see there are a couple of tools to extract the data
directly: coastlinecheck
(http://svn.openstreetmap.org/applications/utils/coastcheck/), and
osmcoastline (https://github.com/joto/osmcoastline/). Both of these
process planet.osm.pbf, which sometimes needs a 64bit machine with a
certain amount of ram etc, depending on what exactly the tool is
doing. I have an older computer with 2gb of ram...
Would it be possible for me to use either of these tools?
