- The properties of each layer also include transparency options and metadata information such as the product, satellite, geometry and analysis period.
- The minimized Time Series and Cross-section windows are located in the lower left hand corner of the browser window.
- The 3D view only allows visualization of layers and user-drawn polygons and cross-section lines. The TREmaps® tools are currently inactive in the 3D view.
- Error messages are displayed in the lower right hand corner of the browser window.
