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:
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.
Yesterday the United State Geological Survey (USGS) released the first 38,000 scenes collected from the recently launch Landsat 9 (September 2021). After much calibration and quality assurance here are some of the first clear images of Iowa. For more images visit USGS Earth Explorer: https://earthexplorer.usgs.gov/.
She highlighted the completion of the Historic United States Geological Survey (USGS) 24,000 Topographic Map series ArcGIS service. The 24k historic topo maps were downloaded from the USGS TopoVieweras georeferenced .tif files, inventoried and put into an ArcGIS mosaic dataset. The dates for those maps for Iowa are 1949-1986. They are currently in a published map service on ortho.gis.iastate.edu and as a layer in the Iowa Geographic Map Server (see map below.)
USGS just released a Story Map summary wrapping up 2021 and the exciting developments with the Landsat mission including a newly launched satellite and 10 million scenes in the archive mark two high points.
Landsat 9 is scheduled to be launched on September 16, 2021. This will mark almost 50 years of earth observation by US satellites. In preparation for this historic launch, we will be sharing several interactive documents about the history of the Landsat mission as well as the information about the Landsat 9 mission.
Today we would like to share with you, A History of the Landsat Program, developed by Ellie McGinty at UtahView. It’s an interactive Google Earth Tour, which documents major moments in earth observation history through a combination of maps, text, and curated images starting with the founding of the United States Geological Survey in 1879 through the birth of NASA in 1958 to the conception of Landsat in 1970 and all the way to the present day launching of Landsat 9.
On November 1st, IowaView staff participated the “meet-a-scientist” at the annual Reiman GardensSpirits in the Gardens event featuring a self guided pathway with hundreds of carved pumpkins as well as scientists to meet along the way. During our shift, there were over 250 visitors of all ages. We were able to share posters featuring remote sensing and GIS, which included aerial imagery of Ames and Reiman Gardens dating from the 1930s to 2019. Participants enjoyed seeing change over time as Ames has urbanize over the last ninety years. Staff gave out goodie bags with AmericaView poster, USGS trading cards, and Earth as Art bookmarks and booklets.
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.
This post will describe the second workshop the ISU GIS Facility and IowaView hosted as part of the 2017 Iowa 4-H State Conference, “Start Your Future Here.” The second workshop, “Start Your Open Street Map Adventure Here,” gave students a brief introduction to GIS and remote sensing as well as a short discussion of open street map and its interface. Then 4-Hers were asked to practice using the mapping interface through the TeachOSM application. The group started by mapping a small northwest Iowa town, George. As you will see from the screen shots, the 4-Hers made significant progress for this community, mapping over 400 buildings. Comparing the before and after pictures, notice the large number of buildings added in the central and northeast parts of town.

For the second activity, students worked on a project sponsored by the United States Geological Survey (USGS)’s Volcano Disaster Assistance Program (VDAP) to help map communities near active volcanoes. the 4-Hers mapped roads, buildings, and rivers in several small communities near Mt. Galeras in Columbia as part of their emergency preparedness. According to project description, “Galeras is an active Andean stratovolcano that is located in the Narino department, near Pasto (population: 450,000 Colombians). Galeras is the most active volcano in Colombia and is known for regular eruptions, the most recent occurring in 2000, 2002, 2004, 2005, 2007, and 2010.” The students did a great job mapping with both projects. Between the two projects over 500 nodes were created and over 3,000 nodes were created. Hopefully these activities will lead to future mapping interest.
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.
LouisianaView is loaning us theirEarth as Art art exhibitfor the month of February. We are working to create a fun and educational art exhibit for all. You will not want to miss this exciting event. For a preview, visit Earth as Art online:http://eros.usgs.gov/imagegallery/earth-art-4.
