- Of course there's a xkcd about it.

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

  Maybe that's something for you?
  
  this is really cool, thanks so much
  
  Wow this is unreal
  
  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.
  
  That is something I didn’t know I needed, thank you!
- Good point. They're always impossible to find unless you know exactly where to look
- Download the surveyed water data, turn the layer on, profit?

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 Get that, turn on cartographic overlays (outdated scans but still useful), aerial imagery, download and import nhd data, pull up ngs website, and enjoy.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.
  
  yeah, it's addictive, I started with sidewalks in my neighborhood, 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.
  
  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
  
  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.

I heard you're not supposed to go source-to-mouth
- Sometimes, in the heart of obsession, it's forgivable to go source to mouth.
- Iz only smellz...
- Precisely why many do it

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.

Trying to find the right zoom level that shows the name of the river

I feel targeted.

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 user 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.
- I used to process aerial imagery and it was so good for this reason. It was like playing Geoguesser as a job.
  
  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.
  
  Nostalgia is an incredibly powerful thing. Especially when it comes to elderly and/or people with dementia.
  I’ve done a fair few VR demonstrations with my Quest headsets. Google Streetview-like apps are always a big hit with everyone. It’s a great way to revisit places from the past with a good sense of presence. And of course to see a place you’ve always wanted to go.

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

Why follow a line when I could make a DEM from some LIDAR data, then run Aspect and Accumulation functions and dileneate watersheds?
- 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?
  
  I attempt to create a TIN from survey data collected with the tree survey.
  Rolls RPLS....
- This guy maps

Lol, relatable.

Me exploring railroads on GSV....

Bro wtf where does the river come from? I tried following it upstream on gmaps but it just stops in the middle of some field. Not even a mountain or something
- It goes... underground!

Modern technology has really spoilt us

Whom amongst us

Prefer to go the other way around.

I just make imaginary railways with the measure tool
