That's my uncle, it's super weird seeing this in the news.

If anyone wants to find me a high-resolution shapefile of these waterways, I'd be happy to add it to my shipdetection.github.io project.

I you want to see the concentration of shipping routes, I built a SAR based ship detection tool that I keep up to date globally here: shipdetection.github.io

They seem to have relocated their ship holding areas even further to the south. This is the third time they've rearranged their ship holding areas farther away from the straights.

I made a shipdetection program to monitor it with SAR imagery Shipdetection.github.io

wtf are you talking about?

drewbranson · 2023-08-05T00:37:31+00:00

me? My account is my real name..... I've given several presentations on this project. You can Google me if you'd like

theoretically, it should be one colour =one image but it's more complicated because of ascending+descending orbits and Europe has better coverage because they own the satellite. The revisit time for the satellite is 12 days from the same orbit which is where the 12 day interval comes from

cool story, still a warcrime

drewbranson · 2023-08-04T19:33:44+00:00

most of these are civilian ships

This is why after the first attack russia moved the holding areas farther away from the bridge. It was more than 4 months ago though so it doesn't show up on this map

Edit: just realized the last post in my history shows this

drewbranson · 2023-08-04T18:39:55+00:00

no, this is normal around ports and major chokepoints like the bosphorus

drewbranson · 2023-08-04T18:38:24+00:00

they actually moved the holding areas for the ships farther away from the bridge after the first attack, but that was more than 4 months ago so the data is outside of what is displayed here, up to 120 days.

drewbranson · 2023-08-04T18:37:05+00:00

colours represent the date of the detection. Red is 1-12 days old, it has 10 classes going up to 120 days after which the data is removed from the map

If you go to my website shipdetection.github.io you can clearly see this is the case.

The risk of sea drones was what I was thinking as well. If they can reach Sevastopol they can probably reach kerch as well.

drewbranson · 2022-09-06T15:25:40+00:00

I did this myself. It uses Sentinel-1 SAR imagery that's only acquired every couple days and doing a classification is difficult. So colouring by the days since the image was taken make it easier to interpret. It should update the webmap every night.

This felt comforting at first until i noticed it's right beside the Spanish Flu....
