A Closer Look at Natural Disasters Using GIS
Conditions of Use:
No Strings Attached
Rating

As if they are environmental engineers, student pairs are challenged to use Google Earth Pro (free) GIS software to view and examine past data on hurricanes and tornados in order to (hypothetically) advise their state government on how to proceed with its next-year budget—to answer the question: should we reduce funding for natural disaster relief? To do this, students learn about maps, geographic information systems (GIS) and the global positioning system (GPS), and how they are used to deepen the way maps are used to examine and analyze data. Then they put their knowledge to work by using the GIS software to explore historical severe storm (tornado, hurricane) data in depth. Student pairs confer with other teams, conduct Internet research on specific storms and conclude by presenting their recommendations to the class. Students gain practice and perspective on making evidence-based decisions. A slide presentation as well as a student worksheet with instructions and questions are provided.

Students pass around and distort messages written on index cards to learn how we use signals from GPS occultations to study the atmosphere. The cards represent information sent from GPS satellites being distorted as they pass through different locations in the Earth's atmosphere and reach other satellites. Analyzing GPS occultations enables better global weather forecasting, storm tracking and climate change monitoring.

FORMOSAT-3/COSMIC
Conditions of Use:

Rating

The FORMOSAT-3 (Taiwan's Formosa Satellite Mission #3)/COSMIC (Constellation Observing System for Meteorology, Ionosphere & Climate) mission involves deployment of six satellites. Using the radio occultation technique, these satellites will interact with GPS satellites and Earth systems to gather data on our planet’s atmosphere. This mission not only has great value for weather, climate, and space weather research and forecasting, but also geodesy, gravity research, and other applications. Assimilation schemes are being developed to effectively integrate the data into existing operational weather forecasting models.

The concept of geocaching is introduced as a way for students to explore using a global positioning system (GPS) device and basic geographic information (GIS) skills. Students familiarize themselves with GPS, GIS, and geocaching as well as the concepts of latitude and longitude. They develop the skills and concepts needed to complete the associated activity while considering how these technologies relate to engineering. Students discuss images associated with GPS, watch a video on how GPS is used, and review a slide show of GIS basics. They estimate their location using latitude and longitude on a world map and watch a video that introduces the geocaching phenomenon. Finally, students practice using a GPS device to gain an understanding of the technology and how location and direction features work while sending and receiving data to a GIS such as Google Earth.

Students familiarize themselves — through trial and error — with the basics of GPS receiver operation. They view a receiver's satellite visibility screen as they walk in various directions and monitor their progress on the receiver's map. Students may enter waypoints and use the GPS information to guide them back to specific locations.

GPS and GNSS
Conditions of Use:

Today GPS is critical to positioning, navigation, and timing. The smooth functioning of financial transactions, air traffic, ATMs, cell phones and modern life in general around the world depend on GPS. This very criticality requires continuous modernization. The oldest satellites in the current constellation were launched in the 1990s. If you imagine using a computer of that vintage today, it is not surprising that the system is being substantially updated. Global Positioning System (GPS) is now a part of a growing international con?text-the Global Navigation Satellite System, GNSS. This course dives into how GPS and other GNSS systems are designed, how they operate, and the impacts they have on spatial analysis and spatially-enabled systems.

This website provides an overview of the GeoPad project, the software and hardware components of the unit, and a listing of publications, presentations, and case studies. The GeoPad is a TabletPC equipped with wireless networking, a portable GPS receiver, digital camera, microphone-headset, voice-recognition software, GIS software, and supporting, digital, geo-referenced data-sets. The unit allows scientists to go out in the field as a group or individually, collect GPS-referenced data and share the data instantaneously with each other and with data fusion "collaboratories" hundreds of miles away. It also provides on-demand access to the large database, data summarization and visualization resources at these distant centers to request site-specific information.

Students take on the role of geographers and civil engineers and use a device enabled with the global positioning system (GPS) to locate geocache locations via a number of waypoints. Teams save their data points, upload them to geographic information systems (GIS) software, such as Google Earth, and create scale drawings of their explorations while solving problems of area, perimeter and rates. The activity is unique in its integration of technology for solving mathematical problems and asks students to relate GPS and GIS to engineering.

This series of short videos, produced in collaboration between NOAA’s National Geodetic Survey and The COMET Program, provides an introduction to geodetic datums for anyone who uses mapping products or other geo-spatial tools. 1. What are Geodetic Datums? (4:36) In this video we explain the basic concepts behind geodetic datums, where they are used, and why it is important to know about and use the correct datums. 2. How Were Geodetic Datums Established? (3:12) In this video, we explore the history of geodetic datums in the United States, and how they were established at a national level to assure consistency across mapping applications. 3. What Is the Status of Today's Geodetic Datums? (4:49) Here we examine the use of the current primary geodetic datums used in the US, NAD 83 and NAVD 88, the challenges in maintaining these datums, and the inconsistencies that arise when they are used together with the latest satellite-based mapping technologies. 4. What's Next for Geodetic Datums? (4:41) Finally, we look at current plans for developing more accurate horizontal and vertical datums, (referred to respectively as geometric and geopotential datums), the expected benefits and impacts, and the importance of preparing now to adopt these new datums. This resource is hosted on COMET's YouTube Channel.

In past times, ocean navigators tossed a piece of wood over the side of their ships and noted how long until the ship passed the wood. They used this time measurement and the length of the ship to calculate their speed and estimate how far they had traveled. In this activity, students act the part of a GPS signal traveling to the receiver to learn how travel time is converted to distance.
