1. Questions When have you used GPS? GPS technology uses satellites to pinpoint position on Earth with the aid of a GPS device or unit Have you ever used a mobile phone app that allowed you to use maps to explore information? many apps today include GPS technology, as well as elements of a GIS. http://education.nationalgeographic.org/ac tivity/introduction-gis/

2. GIS Geographic Information System: a system or tool for displaying and analyzing data related to positions on Earth’s surface Crime patterns in a city Animal migration patterns Setting up a sports franchise Condo construction http://education.nationalgeographic.org/ac tivity/introduction-gis/

3. GIS allows users to display and analyze the data GPS provides users with geographic data. http://education.nationalgeographic.org/ac tivity/introduction-gis/

4. How might some industries or companies use GIS in their work? Technology: supports design, implementation, and management of communication networks for the phones and Internet connectivity. Transportation: managing and designing road networks and transportation infrastructure. Plan efficient routes for medical emergency vehicles to travel between emergency sites and medical care facilities Where to build new stores and restaurants. Marketing companies use GIS to decide to whom to market those stores and restaurants, and where that marketing should be. http://education.nationalgeographic.org/ac tivity/introduction-gis/

5. How do you make the data? Paper maps (ex: political, topographic, thematic) GPS Remote Sensing http://education.nationalgeographic.org/ac tivity/introduction-gis/

6. Remote Sensors Collect data by detecting the energy that is reflected from Earth. On satellites or on aircraft. o Monitor shoreline changes-erosion prevention. o Monitor ocean circulation, ocean temperature, wave heights, and track sea ice. o Hazard assessment: Track hurricanes, earthquakes, erosion, and flooding o Natural resource management: Monitor land use, map wetlands, and chart wildlife habitats. http://education.nationalgeographic.org/ac tivity/introduction-gis/

7. Thematic Maps Emphasizes a particular theme or special topic such as the average distribution of rainfall in an area Do not just show natural features-used as reference points to enhance one's understanding of the map's theme and purpose. Used in GIS because we can compare maps with certain themes such as population and climate http://education.nationalgeographic.org/ac tivity/introduction-gis/
