Re: ENC vs RNC and no more RNC

NOAA had a webinar last week dealing with some of this stuff.


They have posted the slides here, its worth taking a gander.

Sure. No problem, I will do that soon with a warning that this is only tested by me in one area with one kind of chart.

Re: ENC vs RNC and no more RNC

Gypsyjon...


Thanks for the link to the NOAA presentation.
On review, I find that the descriptions of the various ENC display options are consistent with current OpenCPN ENC rendering practices. And both are derived from internationally recognized S52 standards as implemented by type-approved ECDIS systems.

I suggest that users should begin to make themselves comfortable with the concepts of display control for ENCs, especially the specific terminology used. It is a new world coming, and it will pay to be ready.

Re: ENC vs RNC and no more RNC

For those wondering what we are talking about here is side by side ENC and RNC (mbTiles) off the cost of San Francisco. This is a screen shot of Raspberry Pi running a voyage simulation created by fellow CFer Paul Elliot. Resolution was lost due to CF requiring JPGs to be really small.

Re: ENC vs RNC and no more RNC

I think that this is a good-News-bad-News story. NOAA gets to keep all of their data in a single format. Thatís good for consistency and update frequency. You get to (or have to) customize your own charts. If you do it poorly, then youíll have a lousy chart. The good news is that they realize that theyíll need a lot more small-scale chart data. The bad news is thatís likely to take a long time and may never happen for some small bay in Mexico.

So donít throw away your 1938 Admiralty chart of Bahia Tenacatita. Or your 1976 charts of the Perlas Islands.

WARNING - This is still early days and I like it for NOAA ENC charts in my area. Use at own risk as a starting point!
* I use the Vector Chart Zoom at +5. At the default zoom level of 0, you have markers and other details vanishing at certain zoom levels when they were present zoomed more out and more in.
