# Imagery Data

## Overview

Here's an example json file which places some sample WMS items in an open group called "WMS example", at the top of the catalog:

```json
{
    "catalog": [
        {
            "name": "WMS example",
            "type": "group",
            "isPromoted": true,
            "isOpen": true,
            "items": [
                {
                    "name": "Solar Satellite DNI & GHI with datetime picker",
                    "layers": "Solar_Satellite_DNI_2014",
                    "url": "http://gis.aremi.nationalmap.gov.au/bom/wms",
                    "type": "wms",
                    "maxRefreshIntervals": 9000,
                    "showDatetimePicker": true,
                    "useOwnClock": true,
                    "featureInfoTemplate": {
                        "name":"{{GRAY_INDEX}} W/m2"
                    }
                },
                {
                    "name": "Solar Satellite DNI & GHI with initialTimeSource",
                    "layers": "Solar_Satellite_DNI_2014",
                    "url": "http://gis.aremi.nationalmap.gov.au/bom/wms",
                    "type": "wms",
                    "maxRefreshIntervals": 9000,
                    "initialTimeSource": "2014-06-30T22:00:00Z",
                    "featureInfoTemplate": {
                        "name":"{{GRAY_INDEX}} W/m2"
                    }
                }
            ]
        }
    ]
}

```


## Setting the default date

Use `initialTimeSource` to do this.  The allowed values are a valid ISO8601 datestring, "present", "start" and "end".

## For more

For more information, check the descriptions under each of the [catalog items](../catalog-items.md) (eg. WMS).
