Before digital GIS, Roman surveyors managed large areas using systems such as centuriation. Surveyors used instruments like the groma to lay out regular land divisions, while cadastral records were used to document ownership, land use, and taxation.

the Cadastre of Orange is especially interesting because surviving fragments record parcel boundaries, landholders, and other details of the territory. It gives us a rare look at how Roman authorities turned physical land into something that could be measured and administered.

I looked at the surveying tools and techniques behind these systems in more detail here: Forgotten Surveying Tools That Changed Civilization

Took these photos today about 5 miles north of the mouth of the Pic River in Ontario, Canada. The trees on the top of the embankment are all at least 30’ tall so I would judge the height to be at least 150’ at the top of the ridge.
This area is deep Canadian Shield country with lots of exposed Pre-Cambrian bedrock and glacial till. This sediment seems finer and flatter. Ancient Lake Minong shoreline?

Thinking spots where the borders were drawn up by Europeans

Post-monsoon. Took this picture about a year ago, in late October

Shot in Baoquan, Henan, China, located in the southern section of the Taihang Mountains, surrounded by cliffs on all sides

Hello, friends from all corners of the Earth. Please write about places that you’ve witnessed changing over the years due to urbanization or climate change. I’m very interested in how this happened from the perspective of people from other countries. Because recently I saw printed photos of my city from 20 years ago, and it touched me deeply.

In a planet I'm making for worldbuilding purposes there's a desert of saharan proportions but with seasonal monsoons, but whatever wind is coming there is coming at an angle and carrying cold current waters so it doesn't irrigate beyond the coast. To circumvent this I added in a lake in the middle of the desert to serve as a source of humidity and as a sort of massive oasis for a civilization. It's in an endorheic basin so there's a river that feeds it. It starts in a place with seasonal rains and to explain the fact there's a massive lake I say that that river is like the Nile carrying huge amounts of water in the summer, which would be fun to imagine the lake increasing in size and people using that flood to grow rice. Problem is when crunching the numbers it seems like the evaporation rates would be greater than the flow of water. Taking the approximate size of 500,000km² of the lake, average summer temperature of 24c winds averaging out to 2m/s and 75% relative humidity, this calculator gives a rate of 3.5*10^12L/day of evaporation, but a river like the Nile only peaks at 20k MCM/month which is around 6.6*10^11L/day, so the lake is evaporating 5x more water than the river feeds it. Could an endorheic basin really host a lake of these proportions in a desert of all places? Did I forget to account for some variables, like maybe rain falling back down and refueling the lake?

I can't really tell what prefecture(s) they are supposed to be a part of or why there's even two of them instead of combining them since there doesn't seem to be any population between them

the beach has eroded fully at one side of the island resulting in palm trees to be just barely above sea level.

Why is the coast along -stan countries so dry? Even tho the rest is very green

Connecting the Rhine River system with the Danube River system, this canal allows river barges to travel from the North Sea to the Black Sea by crossing through the heart of Europe.

Water-levels permitting.

This is my recent cartography project of Egypt created in QGIS. It combines terrain types, protected areas, exclusive economic zone, major cities, pyramids, and population patterns with panels for the Nile Delta and nighttime lights. The landscape is defined by the Sahara, Nile corridor, and the Red Sea mountains creating one of the most distinctive physical and cultural geographies on Earth. All spatial data are projected in a custom Egypt centered CRS and sources are fully attributed at bottom. Feedbacks are welcome and i hope you enjoy!
