 * **Tiled Group Name** - When accessing visualizations through TWMS, the *TiledGroupName* value is utilized instead of the layers identifier. The *TiledGroupName* can also be generated by replacing all underscores in a visualization's *Identifier* from GetCapabilities with spaces and appending " tileset". For example:
     * **Identifier** - MODIS_Aqua_CorrectedReflectance_TrueColor
     * **Tiled Group Name** - MODIS Aqua CorrectedReflectance TrueColor tileset
-* **Time** - Insert the date (e.g. 2013-08-21) or datetime (e.g. 2013-08-21T00:00:00Z) you are requesting. If not time is provided, you can add an option to your GDAL command to specify the value, e.g., `-oo Change=time:2020-02-05`

 This file shows one of the main advantages of the TiledWMS over other GDAL WMS minidriver protocols. Only the minimum amount of information is stored in the handle file. No fiddling with bounding boxes, tile sizes, number of levels is required. Getting the detail correct becomes the responsibility of the source server. All that is needed is the server URL, the name of the tiled group and optionally a set of parameter changes supported by the tiled group.

 ##### #4 - Generate "TiledWMS" Configuration Files for Specified Datasets
-gdal_translate has a `-sds` option where each subdataset of the input is copied, in sequence. This can be used to generate multiple handle files in a single command. We can use the open options to restrict which gets generated. For example, this generates all the handle files for patterns that contain the word infrared:
