In comparison to a Web Scene there are noticeable differences with how 3D extrusion of layers is handled in ArcGIS Earth.
For example:
Within Scene viewer > Layer properties > Elevation - it can be specified which elevation type is applied to objects.
Within Scene viewer > Layer style - it can be specified which attribute should be applied to create the ceiling (extrusion) of our objects. We have AMSL (m) or the actual height of our object (m) to choose from.
- Our 1st attempt in Scene Viewer saw us try Layer Properties > Elevation > Absolute and Layer style > 3D Extrusion > Options > Attribute Driven Selection (AMSL)– which gave us erratic results (objects did not extrude to correct level)
- Our 2nd attempt in Scene Viewer saw us retain Layer Properties > Elevation > Absolute but try Layer style > 3D Extrusion > Options > Attribute Driven Selection (airspace object height) – which gave us a correct depiction in the scene viewer
All seemed well…. however, when we then tried to view this layer in ArcGIS Earth it is apparent that the attributes to not map across cleanly from Scene viewer to ArcGIS Earth.
- Logically within in Scene viewer > Layer Properties > Elevation > Absolute maps to: ArcGIS Earth > Elevation > Absolute. This is only the case in certain scenarios.
- Logically within in Scene viewer > Layer style > 3D Extrusion > Options > Attribute Driven selection (either option) maps to: ArcGIS Earth > Symbology > Symbol Extrusion > Extrusion mode and Field (either option). This is never the case.
Our Workaround:
The workaround we have at present is to drape all the layers ‘on the ground’ in the scene viewer, the ArcGIS Earth user will see the layer in 2D ‘on the ground’ at initial view. If they want to view in 3D the must do the following
- Right Click Layer > Elevation > Absolute
- Right Click layer > Symbology > Symbol Extrusion > Extrusion mode > select Absolute…….. then in Field select our AMSL height in metres.
This 10 clicks to go from 2D to 3D for each layer.
Resolution we would like:
We would like ArcGIS Earth to reflect the inputs made in Scene Viewer and depict layers correctly in 3D without additional inputs.
OR
We would like to reduce the number of clicks (currently 10) the user is forced to undertake to switch each layer from 2D to 3D.
