I’ve had several cartography students who were in the US Coast Guard. And my daughter’s friend from HOSA joined the Coast Guard this summer.
Since the alternative map theme available today was National Chocolate Chip Cookie Day, and since this week began with propaganda maps and has already included a US nuclear submarine map, I figured why not pay homage to the US Coast Guard. So…
Happy US National Coast Guard Day!
P.S. This map is not endorsed, promoted, or recognized by the US National Coast Guard and no trademarked symbology was used in its creation. It is for education purposes only to celebrate US Coast Guard Day. That being said, the color scheme and mobile-friendly D3 globe is pretty awesome in my opinion. 😉

Hi, please create a map to celebrate August 4, US National Coast Guard Day. If possible, please use an interactive globe projection – orthographic but spinnable and pannable – centered on the coterminous United States with both the Pacific and Atlantic seaboards easily visible, as well as the Gulf of Mexico.
Differentiate the different types of points in the dataset. Allow users to click a point to have an information window (fixed location in corner of window) appear with information about the Coast Guard base or incident, please. Minimize the reliability score, but have it available in the lower area of the info window for each feature.
Style the map using similar color schemes and typefaces as to those found on official US Coast Guard website(s), with attribution and not copying exactly. Do not copy exactly or imply that this map is endorsed by the US Coast Guard, because it is not.
DO NOT show a blue rectangle around selected locations, etc. Alsok please add “Creator: (Ian Muehlenhaus)[https://www.muehlenhaus.com] to the about modal. Also please include a thank you in the about, from Ian, to all those who have served in the US Coast Guard, because I like the Coast Guard. Thanks.
Emphasize the datasets in the visual hieararchy. I have a Mapbox API key if it is needed and makes sense to use a Mapbox globe. However, an ArcScene is acceptable if it works as well. Whatever gets us a panscalar, good looking global basemap interface.

IMPORTANT: on mobile, have the info window panel come up from the bottom, fit within the width of the browser window, and be easily minimizable/maximizable by clicking anywhere on the header bar of it.

I’ve attached two datasets that are exactly the same, just different formats. Use the one that is easiest for you to use.
Thank you!
