Happy Earth Observation Day!
Today we are celebrating remote sensing, the study of the earth using secondary observations from instruments such as planes, kites, drones, satellites as an exciting and powerful educational tool to help us show changes over time.
This year the AmericaView/NASA team has put together a fun and beautiful educational poster!
This week marks 40 years since the Mount St. Helens eruption. The image above is from the USGS Earthshots trading card series. The images are displayed in color infrared which is useful for showing living vegetation in red. The mountains surrounding Mount St. Helens are primarily forest. Notice the extreme change in the landscape from the 1973 image to the post eruption image in 1983. The damage was extensive and ash covered much of the surrounding forest land.

Scroll through the images to watch the forest begin to return as the years go by!
Google Earth Engine is a platform for exploring and analyzing satellite imagery. It is available for academic, non-profit, business and government users.
Several members of the AmericaView community have created tutorials to provide a foundation to quickly begin learning and using Google Earth Engine (GEE). If you are new to GEE, you will want to start with this Google Earth Outreach tutorial. You may need to sign-up for a GEE account with an existing Gmail email address.
For a list of additional tutorials visit the AmericaView GEE Tutorial page: https://americaview.org/program-areas/education/google-earth-engine-tutorials/.
Gregg Hadish gave a great presentation about the Iowa Geographic Map Server to celebrate Earth Observation Day. It was a hands-on demonstration of the Iowa Geographic Map Server ArcGIS App which meant participants could follow along as he explained the various features and functions of the map server. Gregg also showed participants how to leverage map server layers within their own ArcGIS Online organizational accounts and basics for creating their own apps.
Thank you, Gregg for a great demo!
Here are some pictures from our Earth Observation Day event.

Don’t miss your chance. This is a unique opportunity to see a melding of art, science, geography, and technology here in the Ames community. Come see some great art.
Kids and adults can stop in to make a color wheel or model of a Landsat satellite or search the images to complete the scavenger hunt. The exhibit is running through Sunday, February 26, 2017.
Thursday 4-7 pm; Friday 2-5 pm; Saturday 11 am -5 pm
Sunday Feb 19 & 26, 2-5 pm
Read more about the exhibit HERE.
The opening reception for the Earth as Art exhibit is on February, 2, 5-8pm. Several younger visitors were in attendance. They created model satellites, color wheels, and searched the gallery to complete the scavenger hunt. There was gallery talk at 6:30 pm by Brent Yantis, the LouisianaView director and the exhibit collection curator, he explained how the images were selected and shared some of his favorite images with us.
There was a reception of crudites and cheese as well as a King Cake that was brought from Louisiana. The King Cake tasted like a cross between a glazed doughnut and a cinnamon roll, filled with chocolate and cream filling. LouisianaView and IowaView are part of the larger AmericaView, nationwide consortium for remote sensing education, research, and geospatial applications.
IowaView and ISU GIS Facility will be hosting an art exhibit in the Design on Main gallery in February. It will be a unique exhibit that is a fusion of art and science – we hope that the exhibit will inspire viewers with beautiful images from around our planet and also provide a platform for education (satellite imagery, geography, earth science, physics, and art.)
The opening reception for the exhibit is on February, 2, 5-8pm. We are planning to have a gallery talk at 6:30pm by Brent Yantis, the AmericaView collection curator as well as refreshments. AmericaView is a nationwide consortium for remote sensing education, research, and geospatial applications. For additional details visit our Earth as Art exhibit page.

The ISU GIS Facility is bringing an art exhibit to Ames! Earth as Art features beautiful Landsat prints selected from the four Earth as Art collections. We are also producing some k-12 educational activities for our younger gallery visitors to enjoy. The opening reception for the exhibit is on February, 2. We are planning to have a gallery talk by the AmericaView collection curator as well as refreshments. Gallery hours are: Thursday: 4 to 7; Friday: 2 to 5; Saturday 11 to 5. We are also interested in scheduling additional hours by appointment, please contact firstname.lastname@example.org for more information.
We hope to see you there!
I was going through a collection of maps in my basement this weekend and found the map seen below: PORTRAIT U.S.A. – the first color photomosaic of the 48 contiguous United States which was featured in the July 1976 issue of National Geographic Magazine. Here’s to forty years of color photomosaics! Happy Monday!
Here’s a description of the map from the National Geographic website: The first color satellite photomosaic of the 48 contiguous United States, this landmark map was published in July of 1976. The near-true color imagery creates a portrait of the patchwork quilt of the entire country. Trace the Mississippi river from its source to the Gulf of Mexico. See the deserts of New Mexico, Arizona, and California. Follow the Rocky Mountains through the western states. A cartographic benchmark, this map laid the groundwork for the many that have followed. http://www.natgeomaps.com/portrait-usa-map
In the blog post, “When the Earth Began Looking at Itself: the Landsat Program,” Fosco Lucarelli, provides additional history and images of Landsat program. The PORTRAIT U.S.A is composed of 700 mosaic images.
