Dave's Gallery - Remote Sensing Images

A collection of images generated from remotely sensed data, ranging from local to global scale.

Camargo Syncline
The Camargo Syncline in central Bolivia. The topographic data for this image was generated by a stereo-matching algorithm developed by Jim Strong (NASA/GSFC Code 932), originally for the Goodyear MPP, then ported to the MasPar MP-1. The algorithm used two Landsat images of the area, which were taken from slightly different angles; it then found matching points in the two images and computed their elevation from the difference in their positions.

Hurricane Andrew
A 3D view of Hurricane Andrew as it was passing over Florida. It was created using AVHRR images. One infrared image was used for the cloud height data (the higher a cloud is, the colder it is). Visible and infra-red bands were combined to produce a more-or-less realistic coloring. The AVHRR data was provided by Fritz Hasler (NASA/GSFC Code 912).

El Nino
Temperature and wind anomalies in the Pacific Ocean during the December 1982 El Nino. Color represents the sea surface temperature anomalies - blue is cooler than normal, orange to yellow is warmer than normal. The vectors represent the difference between the normal wind stress and that during the El Nino. This image was produced for a poster in a series created by students at the Corcoran School of Art under Sara Tweedie; the posters were for an educational program funded by the Earth Observing System project. The data was provided by Paul Schopf (NASA/GSFC Code 971).
