I need to create an attractive set of static tiles for the USA (based on
shapefiles) to populate a web-server-only (e.g., small-footprint, not
dynamic, not a real map server) online map to embed in a java-based
application without internet access.
My first attempt used ArcGIS to render a GeoTIFF of a layout at high
resolution and then passed the image into gdal2tiles.py
(http://www.klokan.cz/projects/gdal2tiles/) (which is EXCELLENT) to
create a shell OpenLayers app that I can customize. This worked fine,
except the image quality from ArcGIS was horrible, particularly when
zoomed in (no anti-alias).
I'm a now trying to use mapnik (mapnik.org) to create the same image at
higher quality. But I am suffering deeply from an acute lack of
documentation which makes creating the cartography even more painful
(where are recipes, examples, and docs for mapnik?)
Is there something else that I can use to create the tiles needed for
the OpenLayers app? Or is there an easier tool for creating a high-res,
high-quality georeferenced image that can be used by gdal2tiles.py? Any
thoughts would be greatly appreciated.
