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.
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.
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.
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).
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.
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)
