openstreetmaps ftw. Get that, turn on cartographic overlays (outdated scans but still useful), aerial imagery, download and import nhd data, pull up ngs website, and enjoy. Help us map rivers! Even better if you can do an actual ground survey w/ gps.

Okay what is nhd and ngs? When I’m horny for aerial imagery, I’m usually browsing Landsat and Sentinel archives.

National hydrography dataset and national geodetic survey (but I actually meant USGS, they provide a lot of data, their map viewer is a good introduction).
- Pantoffel ( @Pantoffel@feddit.de ) English3•10 months ago
Oh thank you very much. Yes, the map viewer I often use, although I’ve only touched Landsat and Sentinel imagery.

btw NHD data tends to be too large for JOSM to handle… my one complaint about JOSM, I feel it could be more memory efficient. Qgis can be used to process and extract large datasets, just split them up into several files per state. (You also need to merge the source files.) But it’s totally worth the pain, because you get a lot of rich, high resolution data.
Depending on where you live, your state or city might also have open datasets available.

I like to do this for civil constructions.
You ever took a look an desert settlements?
There are so many awesome things to see there, and thinking of all the little humans doing their shit there is mesmerizing.
Kind of Sim city/sims in real life

Agreed, I’ve learned a lot doing this. Sometimes it leads to a story, like the ruins of a federal fire watchtower that was destroyed by arson, or discovering one of the largest fisheries in the country. I’ve also noticed a lot more houses are torn down in my city than might be expected. Whole blocks are empty fields now, or maybe have one derelict house remaining.
It’s also disturbing just how much trash people collect in their yards… and the massive wounds of foresting and strip mining.

Ugh, I was in rural china once and the uncle of my ex threw all his trash in his back yard. Disgusting. Nobody really minded though. They didn’t approve, but they didn’t confront him.

Why do that when you can pull in a hydrological dataset and perform stream network analysis to find the flow path between your points of interest?

smh at folks using googlemaps instead of qgis
