Are you able to download the digital charts off the NGA website onto the memory map software.

These days, under the leadership of the IMO and NOAA, there is a terminology slowly settling in with regard to "digital charts," namely there are vector charts (purely digital, in layers, fully changeable) called Electronic Navigation Charts (ENC), and there are actual graphic images of standard paper charts (exact reproductions, no changes possible) which are now called Raster Navigation Charts (RNC).

We can get both for US waters from http://www.nauticalcharts.noaa.gov/staff/charts.htm

So my question must be, do you refer to RNC or to ENC?

I think from the NGA website they are ENC charts or vector charts. I have downloaded a few raster
charts from the NOAA website which has proved to be very easy.The NGA site seems to offer a large selection of international charts,just wondering if these are compatable with Memory Map Navigator.

Since you are signed up for the online course for Inland and Coastal navigation, I am going to copy this topic into that discussion forum and we can carry on there. There are more instructors viewing that section to take part.

Please answer or add discussion to that section. thanks. --david
