dataLayerGeojsonPolygonPoint
Technical Details¶
This layer uses point data from data web services to determine the color of a polygon. This is helpful, for example, to color a basin based on a single soil moisture station. Given a data type, statistic type, and duration, the output from data web services is searched to find either a statistical value or the novascore, depending on whether a range has been specified. That value is then assigned to the basin where the station is located.
Configuration¶
The following parameters may be specified in the configuration file when defining a dataLayerGeojsonPolygonPoint layer.
| Parameter | Example Value | Default | Description |
|---|---|---|---|
| id | "SoilMoisture" | required | Unique layer identifier. Used only for programming puposes and will not be seen by the user but MUST be unique. |
| basins | ["map/overlay-layers/basins.geojson"] | required | Array of the basin filenames. |
| class | "data-layer-geojson-polygon-point" | required | This specifies the class to use to display a data layer. |
| DWSType | "FractionMU6Hour,Last,1Day" | required | This string represents the data type, statistic type, and duration of output to use from data web services. |
| fillOpacity | "0.3" | 0.3 | Opacity of the polygon fill color. |
| label | "Soil Moisture" | required | Label on menu checkbox. |
| popupTitle | "NAME" | none | Basin attribute to use in the PopupInfo. |
| range | [0.2, 0.4, 0.6, 0.8, 1.0] | If not specified, the NovaScore of the point data is assigned to the polygon | NovaScores are assigned for values up to the value specified so a NovaScore of 1 is assigned for values <= 0.2 for this example. |
| refresh | false | false | Layers that have this set to true will be updated every 5 minutes, or whatever the system-wide refresh interval is set to. |
| stroke | true | false | Whether to include the polygon outline. |
| weight | 3 | 1 | Thickness of the polygon perimeter. |
