Camera
Infrared images
Caption: Normal color photo (top) and normalized difference vegetation index (NDVI) image. NDVI image was derived from two color channels in a single photo taken with a camera modified with a special infrared filter. Note that tree trunks, brown grass, and rocks have very low NDVI values because they are not photosynthetic. Healthy plants typically have NDVI values between 0.1 and 0.9. Images by Chris Fastie.

Caption: Normal color photo (RGB), superblue infrared photo (middle), and normalized difference vegetation index (NDVI) image of trailing arbutus. NDVI image was derived from two color channels in the single superblue photo which was taken with a camera modified with a special infrared filter. Healthy plants typically have NDVI values between 0.1 and 0.9. Note that flowers and rocks have very low NDVI values because they are not photosynthetic. Images by Chris Fastie.

Caption: Normal color photo (left), false color infrared image (NRG), and grayscale and colorized normalized difference vegetation index (NDVI) images. Aerial images were taken by a pair of synchronized cameras lofted by a kite and each is stitched from 12-15 images . NRG and NDVI images were derived from two photos, one taken by a normal camera and one taken by a camera modified to record only infrared light. Healthy plants typically have NDVI values between 0.1 and 0.9. Note that brown vegetation has very low NDVI values because it is not photosynthetic. Images by Chris Fastie.

Caption: Normal color photo (VIS), false color infrared image (NRG), and normalized difference vegetation index (NDVI) images of a yard, pond and adjacent saltmarsh in coastal Louisiana. Aerial images were taken by a pair of synchronized cameras lofted by a kite and each is stitched from 15-20 images. NRG and NDVI images were derived from two photos, one taken by a normal camera and one taken by a camera modified to record only infrared light. Healthy plants typically have NDVI values between 0.1 and 0.9. Note that bare soil, dead vegetation, and boardwalks have very low NDVI values because they are not photosynthetic.

Caption: Normal color photo (left) and normalized difference vegetation index (NDVI) images. Aerial images were taken by cameras lofted by a kite and each is stitched from 8-10 images. NDVI images were derived from two color channels in a single superblue photo which was taken with a camera modified with a special infrared filter. Healthy plants typically have NDVI values between 0.1 and 0.9. Note that bare soil, brown vegetation, and buildings have very low NDVI values because they are not photosynthetic.
