Happy Fall! Observe the changes across the landscape in seasonal images in Northeast Iowa. Snow, forest, farmland. Can you notice the areas of coniferous trees versus deciduous trees and where there is seasonal farmland compared to pasture areas? Also notice the changes along the Mississippi and Upper Iowa Rivers. Enjoy the changing seasons! This year
Welcome to another Throwback Thursday. Today we are going back into the archives to compare imagery from the first five Landsat satellites (all images are featured in natural color). Click on each image for a closer view. Try to notice the differences in resolution and image quality between the different years. Another thing to note
As you look out your window you may be noticing that grass is beginning to green up, the lilac bushes are growing new leaves, and a robin is gathering material for a nest. These observations are scientifically termed phenology – the study of cyclic and seasonal natural phenomena relating to climate, plant, and animal life.
