Stewart Middle Magnet School

Stewart Middle Magnet School

On November 30th, the Tampa office welcomed back eighth grade students from Stewart Magnet Middle School, and on January 9th, we welcomed a new group of students that are in seventh grade. Stewart Middle Magnet School specializes in math, science and technology classes, with a special emphasis on aerospace and aviation. In 2003, Stewart was selected as one of the first 50 NASA Explorer Schools in the United States. The students were all a part of the John Glenn Top Gun Academy. This club is composed of students who have a special interest in aerospace and have demonstrated qualities of leadership and community service. Students apply to be accepted into this program that rewards academics, aerospace interests, initiative and leadership.

The students were eager and excited to hear about DigitalGlobe’s latest achievement, the launch of the WorldView-4 Satellite! They followed the preparations of the launch closely, and even submitted questions that were answered on national television. At the close of their trip, the students that excelled were awared copies of WorldView-3 imagery.

"I want to intern here when I'm in college!"

"The older students told me about this field trip and I've been looking forward to coming here all year!"

The students rotated through four stations that individually highlighted DigitalGlobe’s capabilities: GeoHIVE, Analytics, LULC, and Research.

GeoHIVE (Geospatial Human Imagery Verification Efffort)
At the GeoHIVE station, students had a blast learning about the power of crowdsourcing. GeoHive is DigitalGlobe Services' satellite imagery crowdsourcing platform. We combine the power of the crowd with DigitalGlobe's stunning high-resolution imagery to create accurate and insightful geospatial data. The students searched through imagery of the Tampa Bay area to find baseball fields. Little did they know there was an ongoing competition throughout their time at the GeoHIVE station. Team Milan, Team Osaka, Team Taipei, and Team Zurich competetd against each other to find the most baseball fields. The winner of the competition was Team Osaka! They found 84 features in the map, looked at 1,975 different map views in 925.44 sqkm of imagery, and they accomplished all of this while maintaining an acceptable CrowdRank score.

Analytics
The students learned the basics of imagery analysis and geospatial methods. Each individual took part in an exercise that had each of them search for a missing boat along a small area of the Florida coast. Not only did they need to apply common geospatial techniques to reduce the area of interest but also take into account other factors such as wind speed and tidal conditions. Some students who completed the exercise also discovered certain features that even our exercise creator did not catch including a flock of birds resting on the surface of the water and multiple moving maritime vessels. The fastest student completed the worksheet and found the ship in under 7 minutes!

LULC (Land Use Land Cover)
At the LULC station, students were given the opportunity to utilize the LULC tool to classify areas of downtown Sydney, Australia. They learned color code meanings and how to apply them to various landscapes.

Pink: Buildings/built up area
Grey: Roads
Dark Green: Trees
Olive Green: Unspecified vegetation
Light Green: Grass
Blue: Water
Orange: Bare earth

Research
At the Research station, the students were free to conduct open source research to create a city of Tampa demographics chart. They found that there’s much more to demographics than age, gender, and race, that having a "boring" census is a good thing, and how fortunate we are to live in a place that has up-to-date information readily available on the internet. Research Analysis is critical to providing a client with a comprehensive understanding of their project.


We closed their trip with cookies, punch, goodie bags, and time to answer questions. The students asked insightful questions and were eager to learn more about what we do here in the DigitalGlobe offices in Tampa, FL and what DigitalGlobe does throughout the world to contribute to DG's mission statement.
