King County real-time CSO status in GeoJSON format

King County Real-Time CSO Status

Requires geojson.

Background

Reads the CSO status from King County's web server and combines it with a CSV file of the point coordinates, then creates a GeoJSON file of the current CSO status for King County and Seattle.

The resulting GeoJSON file can be added to a webmap.

Example CSO status data from King County's server:

	CSO_TagName,04-01-2016 09:30:01 AM
	11TH.CSOSTATUS_N,3
	30TH.CSOSTATUS_N,3
	NPDES072,3
	...

The coordinates (lat, lon, EPSG 3857) are in a CSV file.

	CSO_TagName,X_COORD,Y_COORD,Name,DSN
	ALKI,-122.4225,47.57024,King County CSO: Alki,051
	ALSK,-122.406947,47.559442,King County CSO: Alaska St SW,055
	...

Output

The current CSO status is zipped up with the coordinates and properties for each CSO location. Properties included are:

Property	Value
CSO_TagName	Name code for CSO location
DSN	Data Source Name
Name	Long name for CSO location
Time_stamp	Timestamp of most recent query
