Server for marine charts?

[Larry]

Hi Scott,

Do you know of a tile server for US and or Canadian marine charts that will work with TF? Funny, but there are several sources for free topos, but its $$$ for digital marine charts; not worth it if one is just interested in this or that small area.

thanks so much,

larry

Larry,

I don't know of any servers, but I would sure like to find one!  Would love to add a marine layer or two to TopoFusion.

Let me know if you happen on one.

Thanks.

Electronic "unofficial" NOAA nautical charts are available for free online. Not sure how compatible for the structure of Topofusion though. The NOAA server that has tiles is http://www.charts.noaa.gov/OnLineViewer/. You might want to look at a neat aerial mashup that someone did in GoogleEarth at http://marine.geogarage.com/routes/ (discovered through http://googlemapsmania.blogspot.com/2008/03/noaa-nautical-charts-google-maps.html). There is also a site somewhere to download a full non-tiled chart (which I have georeferenced in the past as TF user maps for overlay). I don't recall what format the full charts are in though. Also, somehow maptech.com provides online access to both nautical charts and aviation charts (besides topo). The interface begins at http://maptech.mytopo.com/onlinemaps/index.cfm. If you can figure out a way to bring any of this stuff into TF, it would be great.
