The Layer Properties window contains all of the settings that pertain to a single layer on your map. This overview will explain each of the options.

For an overview of how layers and maps work, see the Maps & Layers topic.

1 - Accessing Layer Properties

The Layer Properties window can be accessed by clicking the Properties option from the Layer's button on the Map Layers Dialog.

Open Layer Properties from the Layer Button menu

Open Layer Properties from the Layer Button menu

2 - General Tab

The General Tab of the Layer Properties contains basic settings for the layer.

Layer Properties, General Tab

Layer Properties, General Tab

Display Label
Name of the layer as it should display in the Map Layers Dialog.

Icon that displays on the layer button in the Map Layers Dialog. This can be changed to any valid image file (PNG, JPG, GIF, BMP).

Clicking Reset will revert to the original icon for this layer.

File Path
Location of the layer's dataset file.

General descriptions of the layer, its source, or its meaning.

Show in Legend
By default, only Dynamic layers are displayed in the Legend Dialog. Check this box to force a static layers to display as well.

Customize Map Display
Launches the GIS Display Editor for this layer.

Export Display Settings
Saves customizations to the GIS Display in a separate file (.ini) which can be shared along with the dataset to preserve changes to the default display.

NOTE: By default, any changes to the default display are saved to the Map project and will not affect other Maps using the same layer. Using this feature will enable all Maps to display the customizations.

Export Layer Definition
For advanced users, click this button to generate a Layer Definition file (.layer) to share layers with other users.

3 - Updates Tab

The Updates Tab contains update options for Dynamic layers.

Layer Properties, Updates Tab

Layer Properties, Updates Tab

Enable updates for '...'
If checked, this Layer will download updates from the specified Url at the specified Interval.

Advanced Users: Use this option to turn Static layers into Dynamic layers.

Check for updates
Number of minutes that will elapse before attempting to update the layer. This value should not be significantly less than the source data update frequencies. For example, if a Temperature readings only update once an hour, do not download every 5 minutes.

Update Url(s)
The Url(s) that should be downloaded at each update cycle.

Advanced Users: Enter the Url to your online dataset here.

Immediately update on reposition
If checked, this layer will attempt to update every time the map is repositioned or zoomed. This is intended for use only with certain maps which rely on coordinate information to generate source data. For example, Lightning layers are restricted to a 150-mi radius from the centerpoint of your Map and will automatically refresh each time you move the map.

Ensure the following files are included... (Download Once)
The Url(s) containing icons, display files, or other related files that need to be downloaded in order for the layer to display properly, but do not need to be updated with every cycle.

4 - Effects Tab

The Effects Tab contains options for repurposing a source dataset into a new display.

Layer Properties, Effects Tab

Layer Properties, Effects Tab

Not all layer types may have effects applied to them. In order to use effects, the layer must meet the following criteria:

  • It must be a points data set (latitude, longitude, value)
  • It must contain at least one numeric field for calculating contours

Apply Effect
This drop-down controls what is displayed on this tab.


Data Field
If one of the latter three options is selected, you must specify which Data Field should be used to calculate contours or gridded points.

NOTE: Applying effects to layers assumes you have some familiarity with the source data, to know which fields are numeric, for example.

4.3 - Effect: None

The default option is None. If a layer is already contoured by default, such as with Temperature or Radar, setting the Effect to None will display the points data from the original dataset.

4.4 - Effect: Contoured Lines/Color-Filled Contours

Selecting the Contoured Lines or Color-Filled Contours option will display additional options:

4.5 - Effect: Equal Distribution of Points
