Cubism – Landsat Style
LouisianaView is loaning us their Earth as Art art exhibit for the month of February. We are working to create a fun and educational art exhibit for all. You will not want to miss this exciting event. For a preview, visit Earth as Art online: http://eros.usgs.gov/imagegallery/earth-art-4.
We had a fun and informative Earth Observation Day. Here are some highlights and pictures:
- There were 24 attendees.
- We had 15 mappers, who helped build a better basemap in for areas in Botswana. Volunteers mapped dozens of roads and over 500 buildings during our mini-mapathon (45 mins)!
Happy Earth Observation Day!
We will be celebrating the day by having a mini-mapathon followed by pizza and an earth observation research talk by Dr. Brian Hornbuckle. Dr. Hornbuckle will be discussing his work with the satellites SMAP (Soil Moisture Active Passive-US) and SMOS (Soil Moisture and Ocean Salinity- European) and ground sensors to determine soil moisture across Iowa.
If you have time for some fun today consider playing the AmericaView Remote Sensing Imagery Game!
Earth Observation Day is only 3 days away! We hope you will join us at Durham Center or one of the other great events going on around the country. Check out all the events at the AmericaView Earth Observation Day Facebook page!
Here’s the image of the week from USGS showing the Cedar River flooding from last month’s heavy rains:
I was going through a collection of maps in my basement this weekend and found the map seen below: PORTRAIT U.S.A. – the first color photomosaic of the 48 contiguous United States which was featured in the July 1976 issue of National Geographic Magazine. Here’s to forty years of color photomosaics! Happy Monday!
Here’s a description of the map from the National Geographic website: The first color satellite photomosaic of the 48 contiguous United States, this landmark map was published in July of 1976. The near-true color imagery creates a portrait of the patchwork quilt of the entire country. Trace the Mississippi river from its source to the Gulf of Mexico. See the deserts of New Mexico, Arizona, and California. Follow the Rocky Mountains through the western states. A cartographic benchmark, this map laid the groundwork for the many that have followed. http://www.natgeomaps.com/portrait-usa-map
In the blog post, “When the Earth Began Looking at Itself: the Landsat Program,” Fosco Lucarelli, provides additional history and images of Landsat program. The PORTRAIT U.S.A is composed of 700 mosaic images.
On June 30, 2016, IowaView staff hosted a mapping workshop as part of the annual Iowa 4-H State Conference. There were 7 students in attendance. The workshop included an introduction to GIS/remote sensing, a summary of a current GIS Facility project, and two hands-on mapping projects in George, Iowa and Mount Singabung, Indonesia.
For various mapping workshops, IowaView has been adopting small towns (Leon, Ogden) across Iowa to continue adding to and filling in the Open Street Map basemap for Iowa. George, Iowa is a small town with a population of 1,055 located in Lyon County in northwest Iowa.
IowaView choose to focus our second project on Mount Singabung, Indonesia which was identified as a top priority by the United States Geological Survey – Volcano Disaster Assistance Program. Sinabung is an active stratovolcano that has had consistent activity since 2010. The volcano poses a significant risk to those living in close proximity. Recent activity includes eruptions in 2010, 2013, 2014. The latest eruption occurred May 2016, killing 7 Indonesians.
The group made over 2,500 edits during the workshop.
Below are before and after screen shots of George, Iowa.
On January 18, 2016, IowaView hosted our second annual mapping party to celebrate the Martin Luther King Jr. Day of Service. Over the course of the party we mapped over 1,500 ways (linear features and boundaries) and over 10,000 nodes (points). Our efforts were primarily focused on the town of Ogden, Iowa and Raung, East Java, Indonesia, an area identified as high priority by the Volcano Disaster Assistance Program.
Below is a link to a story map showing the progress we have made mapping Ogden, Iowa over the last two mapping events we have hosted. http://arcg.is/1VNfIJH
On January 18, 2016, the IowaView staff hosted the 2nd Annual OSM/MapGive Mapping Party at ISU’s Durham Center on Martin Luther King Jr. Day. There were 20 mappers that were able to join in the day of service on site and several that participated remotely. For the first part of the session participants mapped a small Iowa town and then for the second part of the session participants spent time mapping areas around Raung Volcano, in East Java, Indonesia as part of a collaboration with Volcano Disaster Assistance Program.
The 2015 Iowa NAIP imagery is now available in three image services on the ISU Orthoserver:
