      Of course there’s a xkcd about it.

    I do wish there was a river settings to better highlight rivers.

      river-runner-global.samlearner.com

      Maybe that’s something for you?

        If you’re taking requests, could you point me to a visualization that shows the navigable ones (including canals, BTW)?

        There’s another cool site like this that wasn’t as graphically cool but popped up various rivers quickly just by mousing over. Can’t find it right now but I’ll check again to see if I can dig it up.

      Good point. They’re always impossible to find unless you already know exactly where to look

      Download the surveyed water data, turn the layer on, profit?

  • ThatFembyWho@lemmy.blahaj.zone ⁨1⁩ ⁨year⁩ ago

    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 Get that, turn on cartographic overlays (outdated scans but still useful), aerial imagery, download and import nhd data, pull up ngs website, and enjoy.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.

      I spent way toonlong mapping our houses in my neighborhood. It’s always funny to see my work on apps, I’m like shit that street is missing houses I need to get on it.

      • ThatFembyWho@lemmy.blahaj.zone ⁨1⁩ ⁨year⁩ ago

        yeah, it’s addictive, I started with sidewalks in my neighbirhood, and before I knew it, I was mapping parking zones, fire hydrants, trash cans, benches, traffic signals, speed limits, turn lanes…

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

      • ThatFembyWho@lemmy.blahaj.zone ⁨1⁩ ⁨year⁩ ago

        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).

      Thanks for the recommendation! Downloading osm now o7

      • ThatFembyWho@lemmy.blahaj.zone ⁨1⁩ ⁨year⁩ ago

        Be sure to check out the osm wiki! For editing, you can use their web viewer, but I personally prefer JOSM for more advanced work. Vespucci is a great tool for mapping on your phone.

      Sometimes, in the heart of obsession, it’s forgivable to go source to mouth.

    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

    • ThatFembyWho@lemmy.blahaj.zone ⁨1⁩ ⁨year⁩ ago

      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.

    I feel seen :D

    It’s a fun way to do some free virtual tourism. Especially if it’s well travelled places with plenty of used content. Plus, you get to be as nosy as you want, without making people uncomfortable.

    I love looking at odd architecture for example, but not everyone would appreciate me walking around their building and peering intently through the windows.

    • fossilesque@mander.xyz ⁨1⁩ ⁨year⁩ ago

      I used to process aerial imagery and it was so good for this reason. It was like playing Geoguesser as a job.

      source
      • FinishingDutch@lemmy.world ⁨1⁩ ⁨year⁩ ago

        That sounds like an awesome job. As someone who loves aviation, photography and maps, I’d probably really enjoy that. How’d you get into that field if you don’t mind me asking?

      My wife and I used to take care of her grandmother. I had a simple VR headset and I would show her parts of cities she hadn’t been to in street view.

    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?

  • chiliedogg@lemmy.world ⁨1⁩ ⁨year⁩ ago

    Why follow a line when I could make a DEM from some LIDAR data, then run Aspect and Accumulation functions and dilemeate watersheds?

    source
    • KrokanteBamischijf@feddit.nl ⁨1⁩ ⁨year⁩ ago

      You’re now playing GIS DnD:

      The LiDAR dataset you’re using was scanned in a forested area and doesn’t include any secondary return data. As a result, your watersheds are occluded and the data doesn’t provide the greatest cartography.

      What do you do?

      • chiliedogg@lemmy.world ⁨1⁩ ⁨year⁩ ago

        I attempt to create a TIN from survey data collected with the tree survey.

        Rolls RPLS…
