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

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 Get that, turn on cartographic overlays (outdated scans but still useful), aerial imagery, download and import nhd data, pull up ngs website, and enjoy.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

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).

Oh thank you very much. Yes, the map viewer I often use, although I’ve only touched Landsat and Sentinel imagery.

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 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 neighbirhood, and before I knew it, I was mapping parking zones, fire hydrants, trash cans, benches, traffic signals, speed limits, turn lanes…

What’s the best tool to map points? I walk my dog and would love to quickly drop a pin for a sewer grate or fire hydrant? Is there something I can do mobile?
