(also called "vector") charts download site: LINK
Use the "get 'em all" option (370M! in one ZIP file) and expand them into where ever you keep charts (typically D:\Charts or C:\Charts). There will be a root folder ENC_ROOT which, when you drag it into Charts, will take all the ENC
charts with it. Tell SeaClear or whatever you use where you hid ENC_ROOT and it should do the rest.
NOAA also has an RNC site ( LINK
) which handles "raster" (also called BSB) charts which are, essentially, printed charts scanned into electronic form. That site is a little more complex to use as it only allows 100 charts to be downloaded at a time and there are 1016 charts in the library. However, if you're on the west coast
and don't care about the Gulf, East Coast
, or Great Lakes
, for example, that makes the job somewhat easier. The files also come in ZIP format and need to be expanded into BSB_ROOT in Charts.
The two forms (ENC and RNC) each offer unique data and the ENC chart coverage isn't quite as great as the RNC chart coverage, so there is value in learning
to cope with RNC's. ENC's and RNC's can be read by any number of programs and even NOAA makes chart viewers (they are not "nav programs") available for free. Or... buy Coastal Explorer from Rose Point Navigation Systems ( LINK
), which will do all of this bookkeeping for you (there is no charge for charts or downloads - CE, of course, is not free).
DISCLAIMER: I have been involved with beta testing and minor background testing for Coastal Explorer but have no other connection with Rose Point Navigation Systems save as a customer.
