    A follow up. I’m comparing these layers, and I can see that NE’s maritime indicators layer is a partial extract from the authoritative maritime boundaries. Sorry about the accusation. Still, why not offer the complete EEZ boundaries as an option, rather than the Pacific Groupings?

    Okay, I’ve put a GIS server together using Natural Earth Data. You are welcome to use these, but I should warn you that this may not be the highest performance, and I can’t continually support it, so consider it a proof of concept. Here are the connection parameters:

    RASTER DATA:

    ArcGIS Server: http://carto.byu.edu:8399/arcgis/services

    (there are a lot of layers there: the one you want is ne_raster)

    WMS: http://carto.byu.edu:8399/arcgis/services/ne_raster/MapServer/WMSServer?request=getcapabilities

    (some software prefers you leave off everything after the ?)

    This is one service, but all the image types are in there as layers that can be turned on and off. The group layers for each image type are set to automatically switch between the three resolutions at 1:10M and 1:22M (which looked right on screen resolution; probably should be higher thresholds for print).

    VECTOR DATA:

    ArcSDE: host=carto.byu.edu, service=5152, database=earth, username=earth, password=nacis

    PostGIS: host=carto.byu.edu, port=5432, database=earth, uesrname=earth, password=nacis

    WFS: http://carto.byu.edu:8399/arcgis/services/NaturalEarth/GeoDataServer/WFSServer?request=getcapabilities

    (as with WMS, some software wants the part after the ?, some doesn’t)

    I have organized these by scale and type (physical/cultural), which you can see in the SDE and PostGIS interfaces, but is hard to decipher in WFS. I have altered the datasets a bit: I merged all the boundaries (use the feature_class to separate them), and I merged all the graticules (there is a bunch of boolean fields to filter out the various intervals). I also slightly renamed a couple layers, so they’d make sense to me.

    I have tested this in ArcGIS 9.3.1 and QuantumGIS. If anyone wants to test it in any other software, let me know if it works. Also let me know what you think of the performance (I assume it’s slow).
