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.

Loess Hills: Iowa Landforms Revealed

Obscured from view by vegetation and built structures, Iowa’s often subtle landforms are revealed through a LiDAR-derived bare earth digital elevation model in a Geographic Information System. Geological and human made features can be seen in this series of LiDAR color hillshade maps from across the State.

Loess

Deep deposits of wind-blown silt define the Loess Hills region of western Iowa. Intricate drainage networks and agricultural terraces are visible in this map from along the West Nishnabotna River near Hamburg.

Algona Moraine: Iowa Landforms Revealed

Geological and human made features can be seen in this series of LiDAR color hillshade maps from across the State.

Algona

The elevated curved features in this map are glacial moraines deposited during the most recent period of glaciation in north-central Iowa. The largest in this view is called the Algona Moraine.

The Algona Moraine is located in north central Iowa.

Oneota

Originally called the Oneota, the central river feature in this map is the Upper Iowa River. The well-defined drainage features are characteristic of the Driftless area of northeast Iowa.

Coming Soon: Earth Observation Day – Tuesday October 15, 2019

When: Tuesday, October 15, 2019
Where: GIS Teaching Lab, Room 248, Durham Center, Iowa State University, Ames, Iowa

This year the ISU GIS Facility in collaboration with IowaView will be celebrating Earth Observation Day. This year the theme is “Geoscience is Everywhere.” We have a great day planned.

To start out our day at 10:30am, Professor Peter Wolter will share how he is using remote sensing to measure forest structure and composition. Then we will have a Humanitarian Open Street Map Event 11am-12:30pm. No experience is needed. First, we will have an Iowa-Focused activity 11:00am-11:45am and then we will focus our efforts on an international Humanitarian OpenStreetMap activity from 11:45am-12:30pm. We will also have pizza and you are encouraged to try our new puzzles.

Introducing Iowa Landforms Revealed

This spring, Gregg Hadish of USDA Natural Resource Conservation Service and staff member of ISU GIS Facility put together a series of images called Iowa Landforms Revealed. The project looks at Iowa geological features using LiDAR. Gregg also used interesting color ramps to give these images an artistic component, inspired by the USGS Earth as Art project. The initial project includes a series of 4 images which debuted at the Iowa Technology And Geospatial (ITAG) Conference in West Des Moines, Iowa, this summer. We will be highlighting each image over the next several weeks as a special series feature on the IowaView blog. Please feel free to leave comments or suggestion for future landforms for us to explore.

Earth Observation Day – October 16, 2018


IowaView, in collaboration with ISU GIS Facility and AmericaView, will be hosting the annual Earth Observation Day celebration, Tuesday, October 16, 2018, in Durham 248 from 12:15 to 1pm as part of Earth Science Week.  This year, Gregg Hadish, a staff member of ISU GIS Facility and Iowa NRCS will be our featured speaker; he will give a hands-on demo of the Iowa Geographic Map Server (http://ortho.gis.iastate.edu/.) Iowa Geographic Map Server is browser-based website for statewide Iowa imagery. Gregg has been involved with the development of the Iowa Geographic Map Server for nearly twenty years.  The presentation will highlight recent innovations to the map server including an updated interface as well as many new features and image services. 

Iowa Geographic Map Server hosts statewide Iowa imagery dating back to the 1930s through spring 2018 as well as layers of elevation data (Lidar hillshade, contours), high-resolution land cover data, and historical data including the 1880s General Land Office maps and Andreas Atlas.  Many of the layers are available as web services within GIS software.  This is one of the most robust, publicly available, spatial imagery datasets in the country. This treasure trove of Iowa imagery that is waiting to be incorporated into your research.  This workshop is for all levels. There will also be time for questions.  If you plan to come, please RSVP with amylogan@iastate.edu as computer space is limited.  

Start Your Future Here – Part I

Recently, the ISU GIS Facility, in partnership with AmericaView, hosted two workshops as part of the 2017 Iowa 4-H State Conference, “Start Your Future Here.”  This conference is a good opportunity for students to try something new.   This was the third year that IowaView has participated in the 4-H conference. For many 4-Hers, this was their first experience with mapping and GIS. We offered two different workshops this year. One workshop was focused on GIS and mapping using the ESRI platform and the other workshop was focused on learning to use Open Street Map for assisting with humanitarian projects.

The first workshop, “Start Your Mapping Adventure Here,” was an introduction to GIS and mapping.  During the session students were presented with the basics of GIS and creating a map.  Then 4-Hers were able to complete several hands-on project to illustrate various mapping products.  

Examples of Park Map Designs

Students used ArcGIS Online to interact with and make sense of a news article about the migration crisis from Tunisia to the Italian island of Lampedusa. They learned how to use tools in ArcGIS Online to answer question related to the article. Some of the tools they explored included the Find box to quickly navigate to places on the map, map notes to mark locations on the map, and how to change basemap imagery to reveal different facets of a place by examining topography and photography. This exercise was based on an exercise found in an ESRI teacher training: “Teaching with GIS: Introduction to Using GIS in the Classroom.”

Next participants were divided into small groups and tasked with using ArcMap desktop to create a map of a new city park which they were asked to design. Through this exercise students learned how to navigate desktop, edit and remove features and then create a map and map properties (legend, north arrow, title.)  See examples of their maps to the right. The idea for this exercise came from materials put out by the National 4-H Council as part of a 2013 National Youth Science Day: Maps and Apps Activities.  The exercise suggested having students manually create layers on paper but we wanted to infuse the activity with technology and introduce 4-Hers to ArcMap.  

Finally, we explored several Story Maps from a very basic map to a multi-media interactive map. Here are two other great Story Maps examples showing to additional styles: the spyglass and cascade.   This gave the 4-Hers exposure to another mapping medium and possibly a way to display data for school projects or 4-H projects.
