Today is GIS Day! We are celebrating in the North atrium of the College of Design. Today is an especially exciting celebration as we are also celebrating the 30th anniversary of the ISU GIS Facility on campus and 50 years of the US Landsat, earth observing satellite mission. Please join us in the College of Design from 11:30am to 2:00 pm. We will have several activities, puzzles, refreshments, educational giveaways, and door prizes.
This week we are celebrating Geography Awareness Week!
The History of Geography Awareness Week:
Thirty-five years ago, the National Geographic Society advocated to create Geography Awareness Week. Geography Awareness Week is a way to celebrate and raise awareness of geography, both as a discipline and as a part of daily life. The National Geographic Society felt the limited exposure to geography in American education was a dangerous deficiency. Without proper exposure to geography, students are unable to make effective decisions, understand geo-spatial and geo-political issues, or even recognize their impacts as global citizens. — see more at the National Geographic Website
This year we will also be celebrating the 30th anniversary of the ISU GIS Facility and 50 years of Landsat, the US Land Satellite mission. We will have refreshments and giveaways. It will be a chance for students interested in the GIS minor and GIS certificate programs to ask questions and to meet with GIS professionals. We have confirmed professionals from the Iowa Department of Transportation coming to showcase some of their work. If other GIS professionals are interested in reserving time to meet with students, please contact Amy Logan.
Well, it’s Water Wednesday. Today’s Landsat highlight is a time lapse video (2007-2017) showing the effect of a 2010 dam breach on the water level of Lake Delhi located in Delaware County in eastern Iowa. Notice the dramatic decrease in water and the exposure of large sandbars and the refilling of the lake as the dam is restored.
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.
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:
Saturday, July 23, 2022 marked the 50th anniversary of the launch of the USGS/NASA Landsat earth observing satellite mission. With the launch in 1972, Landsat has continued its earth observation mission and become the longest continuous earth observing satellite.
We are continuing our celebration of the 50th year of the US Landsat satellite imagery program. This week we are heading to the lake – Clear Lake, Iowa, located in north central Iowa.
Below are four images showing Summer Solstice (6/13/2019), Fall Equinox (9/17/2019), Winter Solstice (12/22/2019), and Spring Equinox (3/18/2019) from Landsat 8. The images are presented in color infrared which shows vegetation in red rather than green for better contrast.
At Summer Solstice things are still greening up while at Fall Equinox the fields are all green and some are beginning to be harvested.
Observe the different states of the lake: open water, snow covered, and frozen.
The topography of the landscape (ie. hills and roughness) are much more apparent with snow on the ground. In the summer/fall images, it all looks flat.
