Traveling Way Back – Landsat Images From Aprils Gone By

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 is the wide seasonal variation between the images. All the images were from the same three week period in April. Some images are have snow while other years are very green.
  • Observe that the Des Moines River is swollen in the Landsat 4 -1983 image.
Landsat 1 – April 5, 1976
Landsat 2 – April 3, 1975

Landsat 3 – April 21, 1980
Landsat 4 – April 15, 1983
Landsat 5 – April 12, 1985

You can explore the raw images using this web app: https://arcg.is/0XrG4f. Happy exploring.


This year we are celebrating 50 years of the Landsat earth observing satellite mission. Landsat data helps us observe changes in our communities and environment over time.


Thanks for stopping by and keep observing the world around you!

Ladies of Landsat – Many Pathways to becoming Remote Sensing Scientists

The Ladies of Landsat have shared some great USGS case study videos showcasing the paths women and girls can take to become remote sensing scientists. Three scientists stories are highlighted: Jill Deines, Africa Ixmucane Flores-Anderson, and Nikki Tulley. Read more and enjoy their stories below:

Africa Ixmucane Flores-Anderson: Using Landsat to Connect Pace to Village – Africa was inspired to help her local community in Guatemala by mapping water quality with Landsat and is now at monitoring deforestation.

Jill Deines: Using Landsat to Map Agriculture Yields and Irrigation Use – Dr. Jill Deines was was drawn to the bird’s eye view of agriculture plots growing up in the Midwest. Now she uses Landsat to monitor water resources and crop yield.

Nikki Tulley: Speaking a New Language of Landsat – Nikki grew up in the Navajo Nation without running water in her household. As PhD student at University of Arizona and Indigenous scientist, she uses Landsat to track drought conditions in her home community.

Championing Women and GIS on International Women’s Day

Today is International Women’s Day. Esri Press has a 3-book series Women and GIS, each book highlights stories and contributions of 30 women doing awesome things with geospatial technology. An exciting companion to the books is a series of 3 webinars in which women highlighted in the books are able to present about their projects. Take some time today to celebrate and explore the achievements of women in GIS.

Here’s more information about the Women and GIS webinar series:
