Mapping Planet Earth For Better Positioning - ESA’s GENESIS Mission
--
https://www.esa.int/Applications/Navigation/Mapping_planet_Earth_for_better_positioning_ESA_s_GENESIS_mission <-- shared article
“ESA’s Navigation Directorate is planning a new satellite whose results will enable the generation of an updated global model of Earth – the International Terrestrial Reference Frame, employed for everything from land surveying to measuring sea level rise – with an accuracy down to 1 mm, while tracking ground motion of just 0.1 mm per year. This improvement, at a stroke, will have a major impact in multiple Navigation and Earth Science applications, including an enhancement on the precision of the Galileo navigation system. This mission, called GENESIS, is being proposed to ESA’s Council of Ministers in November 2022…”

I went looking for a resource for a student, and ended up spending an hour down a rabbit hole of aerial photography.

I was thrilled to discover that sixty years of Tasmania's aerial photos have been digitised and put online. Last time I saw these was in the vaults of the department.

Black and white aerial photograph. At the bottom of the image is water, the land along the water's edge is built up, and the land at the top of the image has a few roads running through it but looks mostly hilly and unbuilt. The photo was taken on a slightly cloudy day and little puffs of cloud obscure some portions of the view.

“Successful space companies are sending up satellites to help improve life on Earth..
Space business is often associated with rockets, space tourism, and attention-seeking billionaires. But the most impactful industry to launch into space in the past decade doesn’t have much to do with any of the above. Their focus is observing Earth, via the many satellites that we use to monitor what is happening on our planet. From weather patterns to human rights violations to chlorophyll production, there is a lot about the world we can learn by looking in from the outside…”

To my surprise, it seems there is no one who is creating and maintaining a dynamic database of global shorelines. The datasets in use come from the 1980s, and almost certainly need updating in places. One would think this would be an important project, given that shorelines are eroding and changing due to the effects of sea level rise. #GIS #SeaLevel

You can merge polygons into larger ones for mapping or spatial analysis in R using {dplyr} verbs. See the example by @jladata . After data prep to add a variable “close2raleigh” to an sf object of NC counties, this

counties <- counties %>%
group_by(close2raleigh) %>%
summarise()

creates 2 polygons. Extra code was needed for that 50-mile buffer. Check out the post:
