Let it rain!

Geshem 🌧️

An interactive rain radar clone running on Mapbox GL, see it live at: https://geshem.space

The entire service is served off of static assets located in S3 buckets:

• A static main index page, React-based JS bundle and other static assets that are uploaded upon deploy
• Radar images that are collected and indexed every minute by a Python recurring task running on AWS Lambda

For some architectural notes on the deployment process go read https://yuv.al/blog/an-architecture-for-periodically-updating-static-websites/

Prerequisites

• Node.js
• Yarn
• Serverless, for deploying the AWS Lambda task

Dev

$ npm install
$ DANGEROUSLY_DISABLE_HOST_CHECK=true npm start

Deploy

Deployment is handled transparently via Vercel.

Cron Task

geshem.space's Issues

Geshem seems to be always one slide behind

If it's 11:17, the last slide in geshem is from 10:50, while the last one in the MAKAM GESHEM site is from 11:00.

Differences from the IMS map

I just discovered this project and I love it. It seems like there's something off in importing data from the IMS radar site.

Geshem is currently reporting scattered rains around Modiin, but it's a clear day, as
reflected in the IMS map:

Mismatch between 140 and 280 overlays

They don't line up:

Review in zoom branch, double check ITM coordinates on govmap.

Add time indication

and keep it synced with the slider

Slider doesn't work on Firefox for Android

(It does work on Chrome)

Attempt to remove noise

Look into noise reduction techniques

See: https://stackoverflow.com/questions/33997176/image-noise-reduction-techniques

Add geolocation for map centering

Mechanism to change cloud overlays

OS X + Firefox rendering artifacts
