Greetings from Camp Landsat: Cities and Suburbs

Greetings from Camp Landsat!

Postcards From Camp: Cities & Suburbs
Are you exploring any cities this summer? Rain or shine, urban planners use Landsat to take stock of city growth and its environmental impact. The front of this postcard features a natural-color Landsat 8 image of Ocean Flower Island in Hainan, China acquired May 6, 2020.

This week’s camp theme is Cities and Suburbs and focuses on the growth of cities and urban areas as seen over time through Landsat images. Urban growth has impacts on the surrounding environment. Visit Camp Landsat to learn more and experience a time-laspse video of urban growth in Qatar, a storymap about urbanization of vacation towns, and learn about urban heat islands in Minnesota. This week’s camp crafts include Color by Number Image Classification and creating a bird house with a “green roof.” Thank you to our friends at NASA for making this fun summer camp possible!

Remembering the 2020 Midwest Derecho

A year ago today a derecho, a series of thunderstorms with hurricane-like winds and heavy rains, struck Iowa with very little warning. The National Oceanic and Atmospheric Administration (NOAA) put together a multi-media story map to tell the tale of this eventful day. Hundreds of thousands of trees were lost or damaged. Homes and buildings were destroyed. Many people lost power for days or even weeks.

Have you visited the NASA’s Earth Observatory? It is a NASA website that helps make satellite imagery relevant to the general public and it is a great place to find images for presentations or use in the classroom. In August 2020, the Earth Observatory featured a comparison of satellite images from July 2020 and August 2020 to show the extent of the derecho damage on Iowa cropland.

Release of Cover Crop ID Toolbox and Handbook

IowaView staff have released the Cover Crop ID Toolbox and Handbook. This toolbox allows users to quickly identify possible cover crop fields using three Sentinel-2 images from the fall, early spring, and late spring downloaded from the Earth Explorer website based on field boundaries supplied by the user. On the project webpage you can download the toolbox which works with both ArcMap or ArcGIS Pro as well as the Cover Crop ID Toolbox Handbook that provides additional details about each step of the tool.

#ConnectedByEarth – Earth Day 2021!

This year NASA’s Earth Day theme is #ConnectedByEarth. Visit the NASA Earth Day Poster website to watch a short video about the inspiration for the poster and discover the gems hidden within the poster. Download your copy of the poster to learn more about bees and our natural world.

IowaView Staff Present at ISU Research Days

This year IowaView Staff are presenting their research at a virtual university research conference. Staff built a poster using a tool called iPoster. Click on the poster below to interact with the virtual poster (available for a limited time, through March 2021).

Exploring the Landscape of K-12 GIS and Remote Sensing Education in Iowa

IowaView staff have launched a study to understand the current use of GIS (Geographic Information Systems) software and technology in K-12 public school classrooms across the state as well as to gauge interest among non-users.  The study has two surveys: one for superintendents and one for K-12 teachers.  These surveys will provide a snapshot of GIS in K-12 education as well as identify barriers and opportunities for the use of GIS technology among non-users.

Here is the link to the teacher survey: tinyurl.com/IAK12GIS.

Please contact Amy Logan for any questions regarding the survey.

OhioView presents Remote Sensing on a Shoestring

Are you interested in learning more about remote sensing but have a limited budget? This February, OhioView will be presenting , “Remote sensing on a shoestring,” and will guide you through how to begin using freely available software and data to perform remote sensing analysis.

Topics for each of the workshops (and their skill level) are as follows:

February 5, 2021, 9am – 1pm (EST):

  • Earth Science Missions Imagery using Google Earth Pro (beginner level)
  • Normalized Difference Calculations with Sentinel-2 using Multispec (intermediate level)
  • Land cover classification of Sentinel-2 images using QGIS (beginner level)

Use this link to register for the February 5 workshop: https://forms.gle/Z269biTar4vU23DU7  The last day for registration for the February 5 workshop will be January 28, 2021.

February 26, 2021, 9am – 1pm (EST):

  • Classification Using Google Earth Engine (intermediate level)
  • Ground validation using the GLOBE Observer app (beginner level)
  • Estimating Evapotranspiration with Landsat using QGIS (intermediate level).
