Timelapse Tuesday – 37 years of Urban Growth in Ames, Iowa

This week we are exploring urban growth in Ames, Iowa. The red areas are showing areas of vegetation that are primarily agricultural in the larger areas, the neon green areas are short grass and trees, the gray color is urban areas, and blue areas are water.

Timelaspse Video of Ames, Iowa 1984 to 2021 – Summer Landsat Images

As you watch the time lapse video notice several things:

  1. The expansion of Ada Hayden (the large lake in the center right of the image.)
  2. How the agricultural land in the center of the images fills in rapidly with development between 2008 to 2021
  3. The increase in permanent water retention ponds in as the city develops.
  4. Many of the red agricultural parcels along Ioway Creek (the left river) become smaller and more developed through the time series.

Compare an image of north Ames, Iowa from 1987 to 2021 – what other urban growth changes can you spot?

Disaster at Lake Delhi – #Landsat50

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.

Geography Awareness Week: Review and Contribute to OpenStreetMap

OpenStreetMap (OSM) is a publicly created and maintained world map – the Wikipedia for maps. Anyone with access to an internet browser can view the map and anyone with a free OpenStreetMap account can update the map. If you are new to OpenStreetMap visit their welcome page to a short introduction: https://osmgeoweek.org/guides/intro .

Here are several ways to get engaged with OpenStreetMap:

~ Review your local OSM basemap for accuracy and consider adding community features that are missing or need updating.

~ Spend time working on a Humanitarian OpenStreetMap project. For a current list of priority project visit: https://tasks.hotosm.org/explore

~ Consider joining mappers around the globe in the November OSM US 30 Days of Mapping Challenge (each day has themed asset to map): https://wiki.openstreetmap.org/wiki/United_States/Projects#30_Days_of_Mapping_-_November_annually
