Amazing!
If we had this in our rivers prior to the recent Chennai floods, several lives and property could have been saved.

#12I made a similar map (though much less pretty) for the US a few years ago: http://whitewatermap.com
This is great! It would also be cool if you could have polylines representing the rivers for each given segment (the putins and takeouts are now on AW, not sure how long they've been up). But nonetheless this is a great resource, thanks!

Also, the links to go to the American Whitewater pages are broken: It gives americanwhitewater.org//content/... instead of americanwhitewater.org/content/... But thanks again, this is really helpful.

#14Just out of curiosity, what's the probability that Twitter would shut down these river gauge accounts because they're not people? Does Twitter have a history of leaving projects like this alone?

I put something together for the US a couple of years back as well. I've been meaning to add some logic around deviation from the mean, etc. but haven't gotten around to it.

There are beyond thousands of twitter account bots that say they are bots—never heard of Twitter shutting one down.

#17This is amazing! I've wanted to do some "citizen science" project in waterways around me. For instance, building cheap sensors that detect temperature/water level/salinity/particulates/etc that are so cheap as to be basically disposable. The sensor itself could probably be made for less than $10 these days using various arduino modules, but I'm stuck on how to have the sensors communicate back to a "base station" to…
I'm looking at something similar at the moment, but in agricultural areas where line-of-sight is inhibited only by foliage and terrain. For my purpose, it's OK to collect an SD card every so often, but I've toyed with the idea of an ESP8266 and a directional antenna to e.g. a mobile broadband router, probably again with an antenna upgrade. Earlier today, I found [1] which - amongst other things which you might be int…
Thank you, you people are awesome!
I just needed to get the correct keywords to google and came across:

The dataplan on some look very reasonable, like $1/MB/Month, but the hardware itself seems cost prohibitive.
I mean, the Dash costs $59 or the Electron at $39 just for the board to send over 2G? You can get a disposable cellphone for I guess I'll just need to wait another year or two until economies of scale kicks in...

There are cellular network providers that specialise in IoT applications, where you pay monthly per device and data transferred. This is the first one from a search for "IoT Cellular": http://www.aeris.com/technology/aerconnect/ Particle run their own, but by the looks of it you have to use their Electron hardware: https://www.particle.io/cellular If you could get people to install an app on their phone, you could us…
I'll throw this out there as well. . .
Windows 10 IoT OS is available too, which is built for something like this.

Search for "M2M" (machine to machine) communications.
There's a lot of this going on over old 2-way paging networks. It's how the non-vaporware "Internet of things" works. There are thousands of air conditioning compressors, refrigeration units, elevators, pumping stations, and other boring but important pieces of infrastructure sending their short messages every few minutes. Often they're plain text, something like "Pump 1: OFF. Pump 2: ON. Inside temp: 71. Outside temp: 52. Faults: NONE." There are little M2M modules for such communication. They tend to be rugged, reliable, and cost a few hundred dollars.
Some of these use cellular service. There are special low-data-rate M2M plans for this. AT&T charges $3.33 a month for 1MB/month if you pay by the year. If you have a protocol that doesn't bloat its data traffic by using HTTP, HTTPS, XML, JSON, and other data hogs to send a few bytes of payload, this works out well.
There's something new called LoRa.[1] This is a standard for low-bandwidth wireless network devices with a claimed 10 mile range. Data rates range from 300 bps to 50 kbps. They run in the 900MHz ISM band, so they have good building and foliage penetration, although the range then drops to a claimed 2-3 miles. Units start around $56 on Digi-Key. There are Internet gateways available, so that many of the little cards can be connected to the wider world.

#20Is it possible to limit zooming out and panning with Google maps? It strikes me that it would make for a better UX if you could limit that behavior to avoid shifting the map out of the relevant area for some of the less savvy users.
