Might it be a good idea for demonstration purposes to use that same BOEM Gulf of Mexico mutlibeam bathymetry you reference in your YouTube video, to illustrate the speed of working with large DEMs, to also illustrate the speed of contouring with Manifold 9.0.165.5? I contoured the east and west TIFF images on my home laptop and it accomplished the task in ~49 seconds and ~39 seconds respectively on the TIFFs where the elevation values are in feet.
As impressive as it is that your laptop could do that so quickly, anything that takes more than a few seconds is not right for a video. Videos are necessarily mass market, which means they must be created for highly impatient attention spans. So, if Manifold can do something in 39 seconds that requires 39 minutes in a different package, well, that's wonderful when you read it in text as in this post, but 39 seconds is an eternity on video. The average YouTube visitor isn't going to stick around while nothing happens for 39 seconds. Some videos cheat that by saying "oh, let's pause until this is done..." and then come back, but we do not like doing that in Manifold, where we prefer whenever possible for people to see the true, authentic effect as it happens in real time. It would be great, by the way, if you could report analogous timings on your laptop with Arc. Please report all the settings and workflow in both cases so apples to apples comparisons can be made. By the way, I got a kick out of this... My laptop is [...] 16GB DDR3 [...] ... It's 140.61 GB in size.
... Ambitious! :-) I would recommend on your laptop for the first few trials starting with a part of the data set and then scaling up, so you know when to start launching the job at the end of the day, to leave it cooking overnight. I have to admit to being curious... what is the use case, the end need, for creating contours on all of Alaska and a big part of Canada all at once? Also, as Art Lembo has pointed out in other posts... Until you get your new workstation, I'd recommend getting an inexpensive 3 TB external hard disk for extra space on your laptop. Those have become very inexpensive. Run it over USB 3.0 and it will be faster than a thumb drive, with plenty of extra space as well. For your new workstation, get a Ryzen with lots of cores, maybe even a Threadripper with 32 cores if you can swing it. :-) By the way... I contoured the east and west TIFF images on my home laptop and it accomplished the task in ~49 seconds and ~39 seconds respectively on the TIFFs where the elevation values are in feet.
... what settings for contours did you use? I just tried on a really old and slow Core i7 with 24 GB running windows 10 with data on an external hard disk, making contours from -3300 to 0 with a step of 300: Transform (Contour Areas): [BOEMbathyW_m] (28.559 sec) Transform (Contour Areas): [BOEMbathyE_m] (46.007 sec) All 8 hypercores were busy, but of course with more memory, some SSD and so on, it would be much quicker.
