The Layers list lets you easily view and interact with layers in your canvas view. Layers include the web service you are connected to, its corresponding footprints, mark up and measurements, and any additional context or project layers that are added to your canvas. There are three different layer types in the Layer List:
- Imagery Layers - any focused layers that are associated directly with the imagery within the canvas view that were selected. This will include the connected web service and its corresponding footprints.
- Context Layers - any non-imagery and non-project collection layers, including the Mark Up and Measurement Layers, and context layers that are included in a web map selected for an Excalibur project.
- Project Layers - any editable collection layers that were added to the Excalibur project during project creation.
Note:
The Project Layers will only be visible when you open an Excalibur project containing an observation layer.
To access the layer list and turn layers on and off, complete the following steps:
- Click Layer List in the imagery exploitation canvas.
The layer list will appear with all available layers currently in the canvas. All layers are toggled on as visible by default.
- Click the visibility (eye) icon to turn the layer on or off in the Map Panel or Focus Panel.
Note:
The web layer and corresponding image footprints are not available to toggle in the Focus Panel.
Layer list transparency
Sometimes context and project layers are overlaid on top of imagery and important objects on the image are prevented from being viewed. The Layers list transparency tool lets you alter the transparency of your layers, so you can control the visibility of each layer.
By default, all layers have no transparency applied and are fully visible. To use the transparency tool:
- Click the 3 dots on a layer within the Layers list that you wish to change the transparency on.
- Adjust the slider to your preference on the layer you want changed.
Note:
The Image Layers are not available to change the transparency. To change the transparency of your image layer, utilize the Image Display tool.Zoom to a layer
Using the Zoom To functionality allows you to zoom directly to the extent of any given layer. To use the Zoom To button, complete the following steps:
- Click the More Options button on a layer within the Layers list that you wish to zoom to.
- Click the Zoom To button.
Time slider
The Time Slider tool is available to Project Layers in the Layer List and can be utilized to filter your project layers based on time. To learn more about the time slider tool and how it works, see Editable collection layers.
