Remote Sensor

This is a remote sensing image of the Rio Grand. There is a set of different images that show the changes over time in regards to the size and landscape changes to the area. The interesting thing I noticed about the images is that color changes describe the changes over time. It does not require on scene data retrieval to evaluate the changes.

This is a sample of Mt. St. Helen, taken by NASA. The LIDAR (Light Detecting and Ranging) measures properties of scattered light to find range and/or other information of a distant target by using an optical remote sensor. The information retrieved can track changes over time in a particular area.
