Data can be viewed as either single-band grayscale, single-band pseudo-color, and three-band RGB. 1. Single-band display is useful for viewing a single continuous variable such as elevation, vegetation indices like NDVI, or precipitation. 2. Three-band display is useful for viewing image data where each of three selected bands are assigned to gradi...
Some data have only a single band and will default to single-band display. Multi-band data will default to three-band display, but you can choose to view just a single band as grayscale. Note that you can also display single-band data as three-band RGB display, but the map appearance will not change. To demonstrate visualizing a single band, let’s ...
Data range
The contrast and brightness of an image can be adjusted using the Range (min and max) and Gamma parameters. Visualization of data requires that a given value range be scaled between 0 and 255 for each band being displayed. The range parameter allows you to adjust the range of values to display. The defined min value will be drawn to 0 and the max to 255, all data values in between the defined min and max range are scaled linearly. Data outside the min and max range are set to either 0 or 255,...
Gamma
Gamma represents the relationship between a value and the luminance used to represent it. Roughly speaking, increasing gamma increases the intensity of values in the middle of the visualization range. It adjusts image brightness and contrast. 1. Using the above adjusted data range, open the Layer Settings again and try setting the Gamma to a lower value like 0.75. 2. Apply the change and you’ll notice that the contrast has increased further.
Opacity
Opacity is the condition of lacking transparency. It is on a scale from 0 to 1, where 0 is transparent and 1 is opaque. It can be helpful for maintaining some visibility of the top data layer while also displaying information from underlying layers. In the example below, opacity has been set to 0.6, which faintly reveals the underlying Google Maps terrain layer. With this data view it is possible to determine which states have the greatest vegetation response for the given time period of the...
A palette allows you to assign colors to the range of values in a dataset to single-band (grayscale) display. A palette is a series of hexadecimal color values. Providing two values sets the colors of the defined min and max value of the dataset explicitly, and all values in between are mapped to a linear interpolation of the color gradient. For ex...
One of the interesting things you can do in EE Explorer is visualize change over time. To do this, you will need to add the same dataset to your Workspace as two separate layers and then set them to show different time slices. The example below will show you how to visualize the rapid urban expansion of Las Vegas, Nevada. 1. Go to your Workspace, s...
Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles.
