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)

Seminar Alert: Reducing Nutrient Loss At Arkansas Discovery Farm

Today, Mike Daniels from the University of Arkansas will be presenting about how the Arkansas Discovery Farm is reducing nutrient loss, defining and building soil health, improving irrigation efficiency and edge-of-field monitoring of runoff. His statewide Extension efforts encourage agricultural producers to adopt conservation practices to protect natural resources and improve agricultural sustainability.

Here is the registration link: https://bit.ly/35AVFMt. The session will be recorded and are available on the Iowa Nutrient Research Center (INRC) website. For more information about the upcoming INRC seminar events: https://www.cals.iastate.edu/inrc/events/list?tid=304.

IowaView Rendezvous at Spirits in the Gardens

On November 1st, IowaView staff participated the “meet-a-scientist” at the annual Reiman Gardens Spirits in the Gardens event featuring a self guided pathway with hundreds of carved pumpkins as well as scientists to meet along the way. During our shift, there were over 250 visitors of all ages. We were able to share posters featuring remote sensing and GIS, which included aerial imagery of Ames and Reiman Gardens dating from the 1930s to 2019. Participants enjoyed seeing change over time as Ames has urbanize over the last ninety years. Staff gave out goodie bags with AmericaView poster, USGS trading cards, and Earth as Art bookmarks and booklets.

ISU Mapathon Greatest hits…show the highlights reel!

Over the past few years the ISU GIS Facility has hosted a number of mapathons. Most of our mapathons have a time set aside for mapping in Iowa and then a time where we focus on international projects.

It is amazing what even a small group of mappers can do to add to the OpenStreetMap basemap in a small town in Iowa. Below are three examples of demonstrating how a mapathon event can add to the OpenStreetMap.

Happy GIS Day 2020! #GISDay

As a way to celebrate GIS Day and OpenStreetMap, we are encouraging everyone to go online either during this week or on GIS Day and contribute to the OpenStreetMap basemap. You may consider improving the basemap in your own community. Here are several projects to consider:

Public Lab Mongolia – https://tasks.hotosm.org/projects/9560/
Public Lab Mongolia (PLM), a local non-governmental organization in Mongolia, is leading the Mongolian chapter for volunteer mappers through the HOTmicrogrant COVID-19 project, as part of their mission to promote open data and disaster preparedness. This mapping will also help with COVID-19 response efforts. This project is to map Ulaanbaatar capital city of Mongolia, is organized by PLM in collaboration with the Mongolian Geo-spatial Association and local universities.

Hurricane Eta – Nicaragua – https://tasks.hotosm.org/projects/9765
Hurricane Eta brought wind, rain and storm surge to the coast of Nicaragua. This project is to finish the basemap of Bilwi (Puerto Cabezas) by digitizing buildings from MAXAR imagery. Available to beginners, there may be tricky tasks in this project as some areas have been partially mapped with older imagery and vegetation can often hide parts of structures. Make sure to review the instructions for tips on how to overcome these challenges and provide high quality data.

And now for something weird: Joseph Kerski’s Weird Earth

Today we will be joining Joseph Kerski, a Geographer and GIS education enthusiast, exploring Weird Earth: Exploring the Earth with Interesting, Bizarre, and Odd Imagery. Joseph provides a narrated video on Youtube (primarily targeted at educators) but you can also explore these fascinating places on your own using this ArcGIS Online map. Thank you, Joseph, for taking us to new places and uncover hidden gems on our planet!

OpenStretMap And Humanitarian Mapping – Making A Difference For Others

OpenStreetMap is a publicly editable map of the world. It’s is often referred to as Wikipedia for maps. Anyone can sign up for an account and begin adding to the map. Edits to the map are reviewed and validated by other members of the community.

In 2010, OpenStreetMap was used as a humanitarian disaster relief tool after an earthquake in Haiti. Volunteers from across the world mapped buildings and roads from satellite imagery in areas that been damaged by the earthquake. Then teams on the ground were able to use that information to assess damage and begin recovery efforts.

Since that time the use of Humanitarian OpenStreetMap has spread around the globe helping in disaster response as well as disaster prevention and many other humanitarian efforts. We encourage you to take time during Geography Awareness Week to volunteer your time and talent to help with some of the following projects:

Suggested International Projects:

https://treasurehunts.storymaps.esri.com/pioneers/. Test your knowledge of some of the pioneers of geography and GIS. Good luck! Learn something new!

Be part of the Global Celebration: Geography Awareness Week 2020!

Join us this week, November 15-21, 2020, as we celebrate Geography Awareness Week. Throughout we will be posting various activities and videos from our friends at OpenStreetMap, National Geographic, and Esri to help you get engage and get informed.

As a way to celebrate GIS Day and OpenStreetMap, we are encouraging everyone to go online either during this week or on GIS Day and contribute to the OpenStreetMap basemap. If you are interested and would like more information about how to get started, please email, Amy Logan.

If this is your first time using OpenStreetMap, sign up for an OpenStreetMap account: https://www.openstreetmap.org/user/new. Then look over this helpful resource from TeachOSM about how to get started and build proficiency with OpenStreetMap: (https://ubique.americangeo.org/wp-content/uploads/2019/09/2_buildings_worksheet_1-2.pdf)
