This website is all about the map. A new, beta version of the map that should work on devices of all sizes (desktop, tablet and mobile), can be found here. The old desktop version of the map can be found here.  The old mobile version of the map can still be found here.  For now, gauges are only available for the Southeast whitewater region - basically Alabama to the Mason-Dixon line.  Watershed boundaries are available for areas in this region except for James River and Potomac River drainages.


Map Key

Layer Controller 

Click blue layers icon to open and close the Layer Controller, which gives you the ability to turn individual layers on and off.   Some layers are grouped together; use the + and - controls to expand and collapse these groups. The round blue controls allow you to adjust the opacity/transparancy of the radar overlays. More information about the map layers can be found here.

Rain Gauges

These are the raindrop icons.  The numbers under the raindrop represent the 6hr/12hr/24hr rainfall totals.  Click the icon for detailed info.

Stream Gauges

The most recent stage and CFS reading (if that gauge records CFS) is labeled underneath these icons.  The arrow icons show the trend of the stream flow:  up means it's rising, down means it's dropping.  Yeah, this idea was totally ripped off from boatingbeta.com -- Thanks, Chris!  Click the icon for detailed info.

Rain and Stream Gauges

Some gauge locations record both rain and stream flow - there are two layers of labels at gauge locations. See above for details.

Map Navigation

Drag in any direction to move/pan the map. Use the + and - buttons in the top left corner zoom in and out. On touch devices, you can also use spread and pinch to zoom in and out. On desktops/laptops, you can hold the hold down the shift key and drag a box with the mouse to zoom into a specific area of the map.  

Credits and Technical Details

Information about the individual maps layers is available here.

Nearly every aspect of RainPursuit uses free and open source software. The gauge data and watershed boundaries are stored in a PostGIS/PostgreSQL database. OpenLayers 3 powers the map interface that runs in your browser. The Layer Controller is offered up by Jean-Marc Viglino. Most of the HTML/php/JavaScript code was developed using CodeLobster, which is free, but not necessarily open source. QGIS has been very valuable in pre-processing and managing the map layers. pgAdmin is an excellent and easy to use tool for managing PostgreSQL databases.

RainPursuit Facebook Group

Although FaceBook Groups aren't the best online forum solutions, it seems that fewer people are willing to use older-school discussion forums these days. So join us on the RainPursuit Facebook Group to ask questions, provide feedback and be alerted to issues with RP or the map layers that RP features.
