I noticed on one of the commercial data repositories, you know, those resources that resell free (public domain) data… one place is trying to hock NOAA RNC data for about $150… Ouch! As a gift to you here’s where you can grab these data for yourself – http://chartmaker.ncd.noaa.gov/mcd/Raster/download.htm – enjoy! About these data – The NOAA RNCs™ distributed here are geo-referenced, full-color images of NOAA’s paper nautical charts, published by NOAA in the .BSB format. NOAA updates the RNCs for Notices to Mariners on a weekly basis. They are an official product of NOAA, and meet the S-61 Standard, “Raster Navigational Charts”, of the International Hydrographic Organization. Think GeoTIFF charts!

OK, so just HOW do you “convert” a RNC/BSB/KAP into a GeoTIFF? I’m dying to know ’cause I use ArcGIS and MapInfo and would love to use the RNC/BSB in both.
Thanx,
Captain Greg

Captain Greg,
You mean you actually got your data downloaded, Congratulations!
I can’t seem to get anything but a BSB error.
For use in ArcGIS check out this: http://www.csc.noaa.gov/products/chartview/

ArcGIS 9.2 reads KAP files natively. However, you may be interested in knowing that you can use the NOAA Chart Reprojector, and it works great. It will dump you stuff into a number of projections (I needed UTM Zone 10 NAD 83 North) and you can select the output as a TIFF. In ArcCatalog you will have to define the projection and update your metadata as well as import the metadata for this series of maps from NBII and then document your process. But there you go!

See example of RNC/BSB/KAP overlay in Google Maps viewer :
http://demo.geogarage.com/noaa
where all the 1018 NOAA BSB maps are hosted in the GeoGarage spatial image web server.

I have tried multiple times, and cannot get the RNCs from NOAA to download at all! (All links lead to dead ends.)
Am I doing something wrong? (Even though I don’t think I am.)

This is awesome, can it be made iPhone friendy?
Joseph // July 22, 2008 at 11:52 pm |
Heh, yep, as soon as it is Windows friendly ;o)
KAP is a proprietary format, so that is the hurdle I don’t think you will get over.
Licensing the SDK for that is unreasonable for the expectations of the iPhone developer’s production cost.
Finally, I haven’t seen many people developing these (currently obscure) special needs software just to be shot down by the loading permissions Jobs/Apple has in place.
I order to make this iPhone friendly you will need to have an iPhone program,api that can read geo reference jpeg200. Convert the KAP to Tiff and then to jpg 2k in the WGS 1984 projection and load into your machine.
I recommend if you can program your own jpeg2000 map api that you optimize the display size resolution “pyramid” that this format is well known for.
At this time I know of no Apple iPhone api or object that can read any wave compressed image format, let alone a GIS friendly one.
Or you can get the RNC’s into your own GOOGLE Enterprise server and serve them tiled over google maps, which iPhone does stream.
If you are good at Ajax, I suppose you can build an ArcGIS sever to serve the data and stream it to you as a jpeg wherever you can connect.
Since all of those options pretty much require you to be a business with some capital to throw around, I suspect it won’t happen soon.
If you can get the RNC’s into TIFF format, tile them so they are small enough to load into memory on the iPhone or downsample them into jpegs and create a webpage for youself the hotlinks to the tile/area you need via a visual or tabular index of links.

Doesn’t this program do exactly what you say can’t be done or won’t be done for the iPhone? We use their MacENC software on one of our research vessels.

The conversion of the NOAA KAP files into tiled tiff files that is much better for mobile applications is already done by Bluemapia Mobile, the free and open source GPS chart navigator for Windows Mobile that I developed and that is also used as the client for the bluemapia.com site.
You can download the source code from Sourceforge or only the mobile application from http://www.bluemapia.com.
Just use Bluemapia Desktop to convert the NOAA chart and then move it onto your mobile phone where you have installed Bluemapia Mobile. You can then open the converted chart, pan/zoom and if you have a bluetooth or embedded GPS, use the GPS to see your position on the chart as well as the usual GPS calculated data (SOG,COG,TTG,Bearing, VMG).
