Are there any good software/websites that let you add notes to a map?
I'd like to write down notes of places in China where friends live or I have visited, to help me learn the geography.
The shape model of the nucleus of Comet Halley was made by digitally manipulating a gridded ellipsoid of about the size of Halley (16 by 8 by 8 km) until its shape matched every image in the data set. There are no images suitable for stereoscopic viewing to add to the shape. This map shows the locations of limbs (edge of sunlit disk, dark lines) in the images and terminators (sunrise/sunset lines, gray areas). Uncertainties are quite large. #maps
Charles Owens was a prolific mapmaker and illustrator that conveyed the international complexities of WWII in a way that was accessible to the average person. People at the time even saved his maps as a point of reference, such as this for the perils of the submarine warfare of the Atlantic and beyond in 1943.
That let Abergel calculate the viewing direction for each image. I used that to estimate a shape represented by this set of images. Numbers define individual Vega images. Giotto basically zoomed in on a single view. The camera's mirror didn't survive to view the departing view. These grids can then be overlaid on images to try to locate features. There aren't many features to locate! #maps
Do you get frustrated by other people's abstractions of geography? Do you have strong preferences about hex cartogram layouts of UK constituencies for the next election? Do you have a better feel than me for parts of the UK outside Yorkshire? If so, please help improve our open source layout of future UK constituencies.
I'm sure there will be people from Scotland outraged at this. There must be people in the SE of England who don't like what I've done around the bottom of London? Please help improve it.
The first time we saw this altered history of Chicago, we laughed and laughed, had always encountered small original versions of the print in books, and thought it was so creative.
But now I worry that centuries in the future a conspiracy theorists will anchor their arguments with the altered image.
I'm greatly enjoying the latest version of the Old Maps Online website. It has a very smooth time scrubber where you can see political borders change through time, and then browse georeferenced historical maps from map libraries like the David Rumsey collection.
Contributing to #OpenStreetMap is really rewarding. With #OsmAnd and its live updates you can see your changes on the map about 10-15 minutes after you submit them. A big difference from #mapycz where you wait days for a review and even longer for the change to show up on the map.
@sesivany I see you fell in love with #OSM The live updates are amazing and it got me motivated to contribute to more OSM too. I'm really happy that Seznam cutting off their users will help OpenStreetMaps that much!
If you're exploring #OpenStreetMap like me and openstreetmap.org is too heavy for you, try #OSMapp (https://osmapp.org/). It uses #MapTiler. It's fast, looks nice and works great on the phone, too. 👌
@xangregg@kristinHenry yes, great maps! I remember seeing those over on The Other Site. That scatterplot in the triangle legend is really a nice addition too.

There is a wonderful period in the late 1950's and 60's where science fact and science fiction intermingle as enthusiasm for the space age was gaining momentum.
In this Solar System map (c. 1966) the latest views from the Mariner IV are mixed with a manned vehicle to Mars and views from the surfaces of numerous planets. There's and optimism that made things feel attainable.
