To celebrate the Landsat Golden Jubilee, consider taking a virtual visit to Camp Landsat!This summer Camp Landsat is celebrating this exciting anniversary with 5 weeks of programming, celebrating the 5 decades of Landsat’s continuous mission. This week the theme is People and Places.
Enjoy and explore many activities from Camp Landsat including:
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.
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.
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:
February is Black History month, and as part of that celebration IowaView would like to highlight a new story map that was recently released by the Tracing Race at Iowa State University. The Tracing Race project funds digital projects that reveal the under-documented history of accomplishment and experience of people of color, and engage with the history of race, inequality, racism, and student, faculty and staff activism at Iowa State University.
The Tracing Race project recently released a Story Map by Gloria Betcher, Ph.D.; Ted Grevstad-Nordbrock, Ph.D. & Jeanne Beck, Ed.S. called Mapping the Black ISC (Iowa State College) Student Housing Experience. It shares the stories of black students as they overcame challenges to find housing in Ames in order to pursue their education at Iowa State College.
“Since its founding in 1858 as Iowa Agricultural College & Model Farm, Iowa State University has allowed Black, Indigenous, and People of Color (BIPOC) to enroll as students. Iowa State’s first Black student, George Washington Carver, enrolled in classes in 1891. At that time, the question of where Black students could live while enrolled at the college became a concern, but it was left largely unaddressed by the institution until after World War II. Prior to that time, BIPOC students at Iowa State College (ISC) were kept from rooming on campus by an unwritten policy that required Black students to room together. This requirement was difficult to meet when so few Black students attended the college at any given time. As late as 1926, ISC had only 13 Black students and had just graduated its first Black woman, Willa Juanita Ewing, according to The Crisis: A Record of the Darker Races (“A Record,” 1926).
The housing situation of most BIPOC students at Iowa State in the years before it became a university remains unstudied in anysystematic way. This ESRI Story Map project is an initial step toward addressing that research gap. It is also intended as a means of illuminating just who the Black students at ISC were and what contributions they made after leaving Iowa State.”
– From the Project Introduction: Mapping the Black ISC Student Housing Experience
This story map is a treasure. It explains the challenges of Black students in the early days of Iowa State College in finding housing and how they overcame those challenges. It provides a map showing many of the early residences of the students around Ames, many of the homes are still there today.
Another exciting feature of this story map is how the authors pay tribute to each of the Black students enrolled in at Iowa State College during this period of history. The authors provide a biography of each of the students and information about their time at the college and life after school as well as picture of the students. This is a great way to remember these students.
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.)
A few years back, Tyler Danielson, a GIS professional at Bolton and Menk, Inc. wrote a book called Lindsey the GIS Professional to help describe working with a geographic information system (GIS). In the book, Lindsey explains the information needed to create a map and how to collect it. Then she shows how to take that information to make a map of her favorite park. It gives readers a good introduction to the basics of GIS.Click here to read the book online: https://www.bolton-menk.com/books/lindsey/Lindsey.html.
Since the publication of the book, there have been several other companion resources produced. They can be found at www.LindseyLovesMaps.com:
At Home Activities – a maze, dot connect, data collection activity, analyzing data activity, drawing maps, and map coloring pages.
