The Australian Bureau of Meteorology publishes rainfall radar images of various sites around Australia. e.g. http://www.bom.gov.au/products/IDR713.loop.shtml
This repository is focused on presenting that data in alternate forms of display.
As such it is broken up into several parts as follows.
This program will inspect a given radar image and generate a simple CSV report on the occurrences of the different rainfall intensity values present in the image.
To make it easier to produce results over many radar images the report-using-file-glob.sh program is designed to generate a single CSV report of all the radar images present in the IDR directory.
To populate an IDR directory with radar images you may like to use the scripts at https://gist.github.com/1340891.
Once you have CSV reports produced from rainfall_stats you may use the scripts in rest-api to load this data into MongoDB and run an API server serving out this data from MongoDB in JSON format.
import-csv-stats-to-mongodb.sh will do the initial import into MongoDB and
stats-rest-api-server.pl will sit and listen for requests for a specific radar
code between two datetimes.
One you have the API server running or a sample JSON file generated from the API
server (try make sample-export) you can open up rainfall-graph.html which
(once you have configured it to find the d3 library) produce a graph of the
different rainfall intensity occurrences over time.
Like d3-rainfall-graph, the code in dygraphs-rainfall-graph produces a graph,
but using the Dygraphs library instead of D3. Dygraphs requires less code and
already supports interactivity. Rather than consuming a JSON file it consumes a
CSV file as produced by csv2dygraphs.pl. A sample will be produced using
make sample-export.
- Try to get the BOM to release the radar images under CC-BY as per the Intellectual Property Principles for Australian Government Agencies so I can release a public demo.
- Allow the whole process to run in real time
- Show source radar image for cursor location
- Allow user to select geographic region to limit results to
- Store radar image in PostGIS as a raster and possibly cut out rainfall_stats and rest-api as a result
