Bedrock overlay poll
« on: April 14, 2019, 03:40:48 AM »
I've often seen users asking about a glaciers bedrock elevation to estimate future retreat. Then some veteran users post a bedrock map, but it's still difficult to compare it to current satellite images. Therefore I want to build a bedrock overlay webpage for all major glaciers. However I'm not sure which of the two presentation styles is better.

You can vote for both options if you have no major preference.

I didn't know what the words meant - "horizontal overlay" vs.
full image opacity".  However, opening the two files, and figuring out that the maroon dot [Test 1- horiz. overlay] is a slide anchor (I think I first saw the tool when looking at before and after photographs of fire-ravaged areas last year, where you can slide one image over the other - back and forth), gave me the information needed to make a choice.
Arctic ice is healthy for children and other living things.

Horizontal overlay is amazing. I now will never be able to avoid this site.

Definately horizontal and a future bookmark. Nice.

I also voted for horizontal overlay.
It would be great, if a comparable overlay were possible for all the Amundsen Bay glaciers and ice sheets!

I'd prefer a slider for opacity. Grey-scale glacier images and colors for bedrock elevation. Cool project.
Amateur observations of Sea Ice since 2003.

Same here. Prefer the opacity presentation but an option for changing opacity level would make it better.

Well done Tealight!
Both seem very goid. But the maroon anchor is a bit awkward to use on a mobile phone... maybe if you use that form, it could be tweaked?
Looking forward to the WAIS version...!

I think both are quite stunning.

Thanks everyone for voting. As I suspected both options have a use case. The problem with combining them was that the template for the image overlay slider and the template for the range slider both had "slider" in the name and interferred with another. I solved it by setting the opacity with a number input field and a button.

The test pages are now removed and the overlays have an offical page:
