Apologies for the delay in getting this week’s podcast up but I am feeling under the weather and haven’t felt up to editing it podcast yet. I hope to have it up by Tuesday.
Note: This is the last post by our Spring intern Aleigha. A big thanks to Aleigha and good luck after graduation.
The significance of location services, prominence of maps, and apps that allow us to familiarize ourselves with geographic locations is on a steady rise. Where we used to depend on paper, or some form of tangible maps or listed directions, technology has drastically increased the demand to have those exact same directions or maps accessible to mobile phones, and other electronic devices such as tablets, and portable GPS gadgets. Location based technologies are always evolving. A perfect example of this would be Mapquest, which was extremely popular at one time but is now a thing of the past. In its place, LBS like Google Maps for Android, Foursquare, and Geoloqi have cropped up – for now.
Geographic Information Systems, otherwise known as GIS, can be described as the computer systems that allow information from maps, objects and routes, and other related subjects such as cartograms, charts, and 3D diagrams to be stored and accessed on a regular basis. The technology used in today’s mapping processes has made the ease of access more readily available and demanding. The Internet and other technological advances had a dramatic impact of all GIS related activities, and also on those who use the product. Termed Web 2.0 in 2005, the second stage of Internet development was characterized by the growth of dynamic user-generated content. Undoubtedly, it is becoming more common for EVERYONE to do or desire to do EVERYTHING electronically, not just GIS professionals.
It is time, once again, for the annual meeting of the AAG. This year Sue, Barb, Frank, and I will all be wandering the halls to present, view presentations, interview, and just enjoy interacting with great geo-minded people. A few points I want to highlight:
- Barb: Tuesday, GIScience Classroom paper session
- Frank: Wednesday, Energy Transitions paper session
- Jesse: Wednesday, Human Geography Poster Session
- Sue: Friday, GIS&T Poster Session
Hope to see you Chicago!
According to the National Oceanic and Atmospheric Administration (NOAA), remote sensing is a science that obtains information regarding objects or areas from a distance, typically using aircraft or satellites to take radar or infrared photography. In 1972, a joint initiative between the U.S. Geological Survey (USGS) and NASA launched the first earth resource satellite (Landsat-1). The Landsat Project is the world’s longest continuously acquired collection of space-based moderate-resolution, land remote sensing data. The remote sensing data collected has been used by agriculture, commercial, education, emergency response geology, government, forestry, industry, and military and many other communities.
According to the International Society for Photogrammetry and Remote Sensing (ISPRS), satellite observation has several advantages. It allows users to observe a broad area for a long period, including change detection and invisible information on the electromagnetic spectrum without visiting the area.
