Open CPN charts vs Visit My Harbour ?

Last year I used oeSENC Charts with Open CPN on the backup nav laptop.

Time to buy a new set of UK and Continent again, but I read that Visit My Harbour does a USB stick with Unified charts on a dongle for similar money.

The role of the laptop is preparation at home, and backup for the on-board Raymarine plotter which is backup for HMSO/Imray paper.


Any users care to comment on their preference please ?
 
Isn't that sort of do you prefer vector to raster?

Vector for me - set the zoom data to what you want and makes it much easier for planning with less clutter on screen, s'pose a lot has to do with what you're used to.

Maybe age as well ;)

That's pretty well what it comes down to. I also prefer vector to raster and although I have both, practically never use raster charts. As GHA says the two options are both up-to-date valid chart sets and won't differ much in detail.

Do you mean there's detail on the VMH charts which is missing from OeSenc?

Sounds unlikely, they're both from admiralty data AFAIK.

For vector you can adjust how much data is displayed at different zooms with a slider.

Don't really care how unlikely you think it is, there is more data on the official charts from VMH, that's why i said it. I have both, just like i said. Do you have both, have you made a comparison ?
 
Have used VMH for some years, and moved to oeSNC this year. oeSNC run quicker on opencpn with my rather old laptop, and with some adjusting of the preferences in opencpn you get a very similar look&feel as VMH, yet with all the advantages of vector - namely clickable objects with full details.

Assuming that the VMH charts you're comparing to are Admiralty rasters, that's very interesting. I haven't used OpenCPN, but most of the screenshots I've seen put me off because the charting is, to me, aesthetically ugly. Presumably what I'm looking at in most of them is OpenCPN's rendering of vector data, so there ought to be scope to make it look nicer, but so far I've not seen an example of anyone doing so.

Would you mind posting a screenshot or two of your "similar to VMH" setup?

Don't have both UK but do have Spain though no raster to compare with, is there an example screen shot you could provide? The providers of Oesenc seem grateful for any info about discrepancies , ISTR there was one, maybe 2 small areas with missing data known about.

Oesenc ARE official charts licensed from Hydrographic Offices , is that what you're using? This years? (Publication Date 2018-04-05) If there is missing data then it's quite a big deal.

You need to decide which of the two highlighted parts of your post are correct, along with you statement that "it sounds unlikely" data would be missing.

I am currently using last years VMH raster charts and last years oeSENC charts. One, maybe two known areas of missing data is one or two too many for my liking. Without studying every bit area of the charts for missing data how do we know there are not 3 or 4 or 5 or 6000000000 bits of missing data. The oeSENC charts are based on Admiralty charts, but off no added value data, so i see no advantage in using them, beyond being able to turn layers on and off. IMO, that advantage is outweighed by the possibility of missing data and the ghastly colour schemes.

The OPs question was

I believe i have adequately responded to his post by sharing my preference, based on my personal experience of running both charts side by side and have given reasons for my preference.

It's getting to be a real tedious mission posting on this forum, i'm considering if my time would be better spent doing something else.

Both. From memory there are 1 or 2 small bays or something with some data discrepancies - google can't find the mention of it now, if you know of lots more which you implied then it's a big deal.

That's why if you have knowledge it would be a good idea to highlight it - what and where is the missing data you mentioned?

If you always makes you so grumpy then maybe good idea ;)


Edit - found it

Have you found another area?
Anyone care to check the Castletown Bearhaven chart to see if the update has worked?

I have both. Started with the VMH raster, played with the oeSENC vector and then went back to the VMH raster. For some reason, I find the raster clearer and easier - but that might just be because it was what I was familiar with (both Open CPN and the admiralty folio paper equivalents ).

Considering they're only £30 a piece, you could get both (OpenCPN clearly handles both!)
