How to Make this Map of a Melting Glacier

Here's how you can use the Sentinel-2 powered Land Cover Explorer to download detailed polygons of ice and water around Alaska's Columbia Glacier over the past six years, and how to turn them into a map in ArcGIS Pro. I got a huge amount of collaborative help on the water and ice styling from Warren Davison and Tommy Fauvell (‪@CartoRedux‬ ...I don't know, it's French?). Here's his channel: / @cartoredux

    I'm new to ArcGIS since I was certified at Ferris State last year and I just want to say that you have been an inspiration. Ever since I saw you appear in the ESRI MOOC sessions I've realized that what I really want to do in GIS is make beautiful maps. Art and practicality are everything I've wanted to achieve. Thank you!

    Rapid fire with lot of tricks (most of them we saw in your previous videos but we love them) to create great map. I'll steal/keep your colour choices for water and ice. Thank you John!

    John, can we one day get an hour long videos making full maps with a workflow? something like maps i see people present about at NACIS 😄

    i love nasis, mostly! the videos of mine that you see are making maps with a workflow. but i've saved you the time of editing it so that it only consumes 8 minutes of your life instead of an hour. :)

    ​@@JohnNelsonMaps ok let me rephrase that, surely the length of the video isn't a good factor but what i meant is that we get all these cool tricks and technicals are great for real but what i think is missing in the cartography community in general is something which Daniel hoffman was doing with this streams on various topics and what i called it a workflow which i would love to see from more experts in the community with their diverse styles and niches. Means teaching people (new generations) on how to put such techniques together, thinking cartography and production related stuff.

    It is also possible to use import symbology tool to transfer the looks one to another. Unluckily that is not a regular Geoprocess tool you could batch. Many layers always a pain when working with symbology. But a good map must use a lot of layers. I wish ESRI would invent Import Symbology Batch tool.

    Batch would be a nice addition to symbol by layer.

    i don't have a video for that actually. i just manually traced those lines in a graphic design program. but you could do it in the GIS if you prefer. just lines.
