Hi Jason,


So great to hear back from you. I'm so pleased to hear about the transition
to ArcGIS Pro, I'm sure that's no small feat! It also seems that I contacted
you at the perfect time.


I'd be happy to receive MGET sooner than when you publicly release it, but I
am in no rush. I don't have a deadline, and would need to get all the
necessary rasters set up first anyway. Memory, and processing requirements
etc won't be an issue on the set up I have.


However, I wanted to use MGET to run the coral larvae connectivity tool. I
just joined a new conservation organization in Jeddah, SA (we're called
SHAMS<https://urldefense.com/v3/__https://shams.gov.sa/index-en.html__;!!OToaGQ!q5NSEorWKn_KzpHvLfegk_rM6e8vntkoQ5Xa1XBv7aHeJX-HfKbYqQz52lnkDQy1gq1UBgNjLukXkJlU7IB-mar6He5HXCN2Z0s$
>) and we're very interested in Red Sea coral connectivity which is why I
thought of your work. If the connectivity tool isn't available, which ones
will be? I see on your website that there are a few oceanographic and
fisheries tools, so maybe I can find another use from MGET if not
connectivity for now.


Again, thanks for your reply. I'm excited that you're developing this and
hope to use it soon.


Anna

Subject: Re: MGET still active?

Hello Anna,

Nice to hear from you. MGET has recently been resuscitated after a long
period in which we had no resources or availability to move it forward. I am
actively working to port it to Python 3 and ArcGIS Pro. The core package has
been completed and I am actively testing it now. It will require ArcGIS Pro
3.2.2 or later and Python 3.9 or later (which comes with Arc Pro). It will be
compatible with Linux as well. The source code will be hosted on GitHub and
MGET will be installable from the Python Package Index using "pip" or similar
package managers.

We hope to issue the first release sometime next week. The number of
geoprocessing tools in the first release will be quite limited. The larval
connectivity tool will not be included. We have done a lot of the work needed
for it—e.g. developing a new tool for downloading ocean currents and other
data from Copernicus Marine Service, and rewriting MGET's interface to MATLAB
so we can run tools written in MATLAB using a modern version of the MATLAB
Compiler. But we don't have an urgent need for the connectivity tool
ourselves, so we marked it as lower priority.

That said, you are the second person to inquire about it in the past few
months. I can see about getting to it sooner rather than later. What is your
overall timeframe for your upcoming project with the different reef system?

I should also mention that for users of the connectivity tool, a very
important aspect of this Python 3 + ArcGIS Pro rewrite of MGET is that it
will run as a 64-bit process now. The connectivity tool requires a LOT of
memory, and having to run it as a 32-bit process on Python 2.7 + ArcGIS
Desktop really constrained the size and resolution of the connectivity
simulation you could run. In moving to 64-bits, this limitation has been
removed. You will still be limited by the amount of RAM in your machine and
by the length of time you're willing to wait for the simulation to complete.
But that will be better than what we had before.

Best,
Jason

Hello Jason,


I hope that you've been doing well! I contacted you about 5 years ago when I
was first trying to set up MGET in ArcGIS. Unfortunately I didn't use the
output that I created for any papers, but it did allow me to make a beautiful
larval connectivity video that wow-ed people in presentations.


I'm now interested in running MGET again. I haven't used ArcMap since then,
but it looks like the entire ArcGIS Desktop is migrating to ArcGIS
Pro<https://urldefense.com/v3/__https://www.esri.com/en-us/arcgis/products/arcgis-desktop/resources__;!!OToaGQ!q5NSEorWKn_KzpHvLfegk_rM6e8vntkoQ5Xa1XBv7aHeJX-HfKbYqQz52lnkDQy1gq1UBgNjLukXkJlU7IB-mar6He5HckqVssc$
>. So before I embark on the MGET journey, I wanted to ask if you know if it
still runs on ArcMap and/or if you have plans to write another program in a
non-obsolete software?


Thank you again so much for this resource. I'm excited to try and get it to
run again - this time for an entirely different reef system!


Many thanks,


Anna Bakker
