Andy, Thanks. I have searched the Internet almost every day for the last 23 years, and have learned never to think something doesn’t exist. Thanks for confirming that there are likely no permanent magnetometer arrays. There could still be someone who does it for fun, and doesn’t tell anyone. I wrote some notes below about

Jordan, Image Acquisition Toolbox: Your online, and now the attached price list, is not appropriate for “Home” users. Today someone fixed the website issue where the license information was not accessible. I could not open my account information. Now, when I look at my account information, “Manage Products”, it has “But Add-Ons” as a working

LOL! When I clicked OK it failed because it could not read my email address. I used mixed case, that is probably why it failed. Why do I even bother trying to help anyone. I can act in good faith and try to do my best to document something. But the systems on the Internet

Is there a way to ask for help? I have many projects that I would like to try, but often am missing critical pieces that probably are obvious or trivial for someone else. For instance, I want to write algorithms for pan tilt zoom imaging with multiple cameras. The algorithms are relatively easy – but

https://www.facebook.com/groups/172438633343696/permalink/877591389495080/ I am looking at daytime uses of all sky cameras. Satellite images are a bit too bulky and not enough resolution for correlations. Need multiple cameras to recover 3D of clouds. I have seen groups aiming at comets, planes, clouds, rain, sky color, daytime astronomy (is possible), sun and moon tracking, shadows, reflections, multispectral,

Robin, Haje, I am looking at global sensor networks, and got to magnetotelluric arrays. For background I was reading about natural signals that can be used for calibration and reference and came to http://ampere.jhuapl.edu/index.html To be explicit, I was at https://en.wikipedia.org/wiki/Birkeland_current and clicked on the link to Project Ampere that took me to https://web.archive.org/web/20050211120508/http://dysprosium.jhuapl.edu/ Then

Orion Nebula WITHOUT a Star Tracker or Telescope, Start to Finish, DSLR Astrophotography https://www.youtube.com/watch?v=iuMZG-SyDCU I am trying to estimate the time and cost for myself. Today is 19 Jun 2021 for me. Amazon link to Canon EOS 5D Mark III body only is $899.99 + shipping and tax – never used Canon, lots of screens

https://www.researchgate.net/post/Is_there_any_paper_scientific_document_that_shows_how_much_mA_is_typically_considered_as_the_input_current_in_the_ERT_and_IP_fields2 Mostafa Ebrahimi, When you ask questions like this, spell out what all the acronyms. IP is mostly “intellectual property” or other things on the Internet. “electrical resistivity tomography” “induced polarization” gives 42,100 entries on Google search. That means it is fairly mature. If you are actively surveying a large region you might

https://www.researchgate.net/post/Please_I_want_to_enquire_How_can_I_download_Geomagnetically_induced_current_data_GIC_of_one_minute_time_resolution_data Alaa Mohamed, Today I was just reviewing “global conductivity models” and “geomagnetically induced currents” for the Internet Foundation. The common practice seems to be to use 1D and 3D conductivity models, then use the fairly dense magnetotelluric (MT) arrays for the changing magnetic fields that induce the changes. There are LOTS of electromagnetic datasets.

£700 vs £7,000,000: Astrophotography Shoot Out https://www.youtube.com/watch?v=4rCyC3_YIME Ryan Fay? Your link in the description is broken (luckyimage) should probably be https://www.astrobiscuit.com/deepspaceluckyimaging There are better ways to combine images from many different sensors. You talked about hundreds?, thousands?, millions?, billions? of people combining images to improve earth surface imaging. Take the human out of the loop.
