dataLayerWMSTime
Technical Details¶
This class displays Web Map Service (WMS) format data layers. WMS is a standard protocol developed by the Open Geospatial Consortium in 1999 for serving georeferenced map images over the Internet. These images are typically produced by a map server from data provided by a GIS database. This class works with an extension of WMS that adds time as queryable dimension.

The following parameters may be specified in the configuration file when defining a dataLayerWMSTime layer alongside all the parameters for a dataLayerWMS.
| Parameter | Example Value | Default | Description |
|---|---|---|---|
| align | false | false | Whether to align times for requested data to 5 minute intervals. Required for some layers (e.g. Nexrad) |
| interval | 5 | 10 | How long between instances of requested data, in minutes (e.g. if it is 10, the data requested will be now, 10 minutes ago, etc.) |
| maxTime | 60 | 90 | The longest ago data to request, in minutes |
| opacity | 0.8 | 0.4 | How opaque the layers should be |
| waitTime | 1 | 3 | How long to wait between loops of the animation, in seconds |
