As the summer approaches, we wanted to encourage you to save the date for an upcoming GIS workshop for K-12 educators being held at William Penn University in Oskaloosa, Iowa on July 20-21, 2022. See attached poster for more details. Also please send us an email if you are interested but can’t make this event. If there is enough interest, we may hold a second workshop, in August or the fall.
Please contact Amy Logan or Debbie Stevens with any questions.
Today’s time lapse video is highlighting the damming of Brushy Creek and the creation of 690-acre Brushy Creek Lake, Iowa’s deepest artificial lake.
Watch the dam development begin around 1994 and then the lake begin to fill around 1998. The Brushy Creek State Recreation Area is a 6500-acre park located in north central Iowa.

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.
What changes do you notice in this Landsat time lapse video?
1) The areas of purple and white in the image are urban areas. Throughout the video they fill in the area from the bottom to the center. The pink areas are farm land.
2) Did you notice the increase in the number of retention ponds (dark blue specks in the urban areas) over time? Retention ponds are used to prevent flooding and provide for water storage in urban areas. As areas become urbanized there is often more surface covered in concrete, parking lots and buildings. There are fewer places for the water to flow directly into the ground.
3) Did you spot the golf course on the northern edge of the city?

Over the last 50 years, the city of Dubai, in the United Arab Emirates, has transformed from a small fishing and pearl diving village into a luxurious, modern metropolis. The population has grown from just over 100,000 residents in 1972 to an estimated 2.9 million residents in 2022. While the beauty and distinction of this city is undeniable, some question the sustainability of this fast-growing city located in a land of desert and salt water. The images are shown in false color infrared. Areas appearing red show healthy vegetation. Notice the dramatic change from first image in 1973 (very little vegetation and urbanization) to 2022 with many areas of red far from the water.
To create these images, individual bands were downloaded from the United States Geological Survey’s Earth Explorer Website (https://earthexplorer.usgs.gov/) in April 2022. The composite false color infrared images were created in ArcGIS Pro using the composite imagery processing tool.

This year NASA’s Earth Day poster is features a series of QR codes which provide an array of information on a number of their missions, programs, and activities. We have provided a key below explaining each of the numbered QR codes along with the link to each code (click on the name to follow the link.)
This year marks the 50th anniversary of the launch of the first Landsat satellite (July 23, 1972). To celebrate fifty years of earth observation, IowaView will be posting various images and gif documenting Landsat in Iowa and around the world. Check back regularly for new images and articles. #TimeLapseTuesday #ThrowbackThursday
