    With all the methods of transportation that are available today, the task of tracking disease has become a increasingly important task. Big organizations have found ways to keep it under control, especially for large events where many people from all over the world condense into one place. They do this by mapping the occurrences of the disease so they can actively measure the diseases and work to keep it at bay. Sometimes this can even get to the very root of the problem and stop the disease completely. -MRR

    The technology used to map our world is crucial to war efforts in Afghanistan and elsewhere. From operations planning to IED detection to monitoring area activities, detailed geospatial information can make the difference between success and failure. Mapping aspects of society, culture, and economic systems can help us understand what is important to people in a given area and how to work with them in times of war. Our soldiers and the civilians they work with deserve the best information that this technology can provide to aid them in their efforts.

    Ever think how your GPS works? Everybody thinks of the navigation gadget in their car as a GPS, but actually it’s a GPS Receiver. The GPS receiver collects signals from positioning satellites in space and the satellites are always tracking the position of every activated GPS receiver. Millions of coordinates are saved in a data base and with the technology. Just using math, the satellites can find your GPS receiver anywhere on the earth. How the map works is lots of people are driving high tech cars on almost every road. Then that information is digitized into a data base, which is then installed into the GPS receiver. -LEB

    Chapter 2, Episode 2 of the Geospatial Revolution was about how UPS was trying to save money and time by creating software to map out the shortest way to get the package to it’s destination. They used the example, “If we save each driver one mile, that’s millions of miles, millions of dollars saved on gas, repairs, and other costs.” Each driver has a device that tracks what the driver is doing, how fast they are, if they ran a red light, etc. This is tracked by the software and used in its database, to see if an even faster time can be achieved.

    Preventing Hunger
    Chapter 2 Episode 4
    There are a billion hungry people in world. Geospatial technology plays a crucial role in helping USAID and many other corporations make good decisions on where food goes, whom it goes to and how much is food needs to be sent. Satellite imagery gives ground observations, rainfall data and overall the possible impact of drought on plant and crop productivity. Satellite data allows people to watch plants from space. This is important in places that they can’t go to personally. They use the satellite information to determine how much assistance should be offered to people and areas in need of food. Geospatial technology helps to help prevent hunger across the world.

    The first episode of chapter four was about how there was a large population center with 200,000 people living there and no map of it. Some people went in with GPS locaters and helped them map out health centers, water sources, dangerous places, and streets to use. At first the inhabitants were skeptical, wondering if they were going to give the information to the government or use it to exploit them. Once their true intentions were discovered, the geographers had all the support they could want. The map was a huge success and the people there were extremely satisfied. -JDM

  7. The city of Portland has invested in various geospatial technologies so that the city government can improve their relationships with the people of the city. They have created “Portland Maps” to provide easy access to information and maps to the general public. People can view maps on specific things like crime data and transportation and get all kinds of information. The city was also one of the first to install GPS tracking on forms of public transportation. “Transit Tracker” gives accurate times of when busses or MAX trains will arrive at a certain location. There is also applications for people to download that provide this information. The local government has made a 3D model of the entire city using LIDAR (Light Detection And Ranging) which uses laser light to capture the location or shape of something in 3D form. They have been able to use this model to ensure the views of Mt. Hood won’t be blocked by any buildings.

  8. In chapter 4 episode 4, the process of mapping Kibera, Kenya in Africa was shown. The place has roughly around 200,000 people in population and it is 2.5 square kilometers with 13 villages. Beforehand, the place had no public school or health facilities so the project was to map everything out and create them. At first the villagers were curious because they had no idea what GPS is and why they wanted to map everything. Yet, they had a discussion about the future of the area and soon the area had team mappers from Kibera to map everything out. It took 3 weeks just for the mappers to map everything. Everyone was amazed and in awe. Soon the original people made a thematic map for education, health, security and more facilities for the people of Kibera. It took a little over 6 months. The place now has police forces for the areas the villagers claimed as danger spots. The people are now informed and the mappers take pride such as Douglas Namale. -MLV

    The episode 1, chapter 1, is the basic introduction of the Geospatial Revolution. In a world where almost everyone is texting, geospatial technology is critical to understanding what is happening to a particular location. Geospatial technology has the speed of the internet, the capability of remote sensing satellites, the same kind of software as Google Earth, and together it’s a big collection of how we view the Earth. The technology receives information from aircrafts, satellites, or a tower in a random place. The source can be from any shared information because any shared information practically has a geo tag.

    Episode 4 Chapter 3
    Disease tracking as evolved from surveying the population to see association between cholera death and water pumps to real time tracking of human migration. Three million pilgrims travel to Mecca, Saudi Arabia every year for Hajj, a religious pilgrimage for the Muslim religion. During the H1N1 pandemic, the Saudi Arabian government became concerned with the extreme amount of international people coming into the country and possibly bringing influenza. With the help of CDC, they provided testing stations and tracked illness with smart phones, recording symptoms and location data that was sent to the emergency rooms in Mecca.

    Mapping has been around forever; it is nothing new. However, the way we map has dramatically changed from the days of scratching on rocks. Satellites in particular have changed the way humans are able to visualize the world around them.
    With technology advancing as it has we all of a sudden are able to put ourselves in the map (iphones, google earth). We are able to get so much information about the space around us. Not just its location, but other details as well. Examples being who liked going there, or what services are offered. We no longer have to look for a place. We are told what places to look for.

    Chapter 4, Episode 2 was about how Philadelphia having the fewest supermarkets per person in America. In 2004 Pennsylvania started what is now a $120 million grant and loan program to help finance fresh food stores in those communities in need of supermarkets. The Food Trust uses GIS methodology to figure out what communities have the biggest need for these supermarkets. They look at where factors overlap, where markets were and weren’t, where people were and weren’t and where there is poverty and isn’t poverty. With these maps they can find where they need to put a store. -JI

    Episode 3, Chapter 1
    This video segment was about the war in Bosnia-Herzegovina, focusing mainly on its peaceful resolution. Starting in 1995, a wave of ethnic cleansing wiped the population of Muslim villages in eastern Bosnia. Soon the west decided to put a stop to this war by splitting up the country, of course they had to make it a fair split or things would only get worse. They used a system by the name of “Power Scene,” this helped them map out Serb and Muslim territory. They also used it to make a road to connect the main Muslim territory to a secluded Muslim city, successfully ending the war. -CMM

    I did the wrong one last time.
    The technology in tracking and knowing where things/people are at any given moment has advanced significantly over the past few decades. Almost everyone now has an electronic that can be traced within a few feet of their actual location. however, this has some strong pros and cons to it. While the tracking can be very useful for law enforcement and can help take care of a problem before it gets out of hand, it can also be used by the public and be turned into a form of harassment and stalking. Is this transparency good? -MRR

    We are becoming individual censors where we can report problems and someone can respond. There was an earthquake in Haiti in 2010 where crowd sourcing was used and really helped the situation. A platform for Haiti was created called Ushahidi. Rescue workers were able to get a real time view of the situation on the ground by an open street map that users could edit and add geographic data too. Ushahidi also offered a number one can text to report problems and needs in Haiti. Because the texts were in Creole, Creole speaking people around the world volunteered to translate the texts. Ushahidi was a support system used by more than 2,000 volunteers. Many of whom were able to help with the Haiti crisis mapping effort just by using mobile technology.

    Episode 2 Chapter 2-
    In my episode of Geospatial Revolution, they discuss the advantages of using technology to collect data for UPS. By collecting data they can find ways to reduce their time used driving so they can cut back on gas emissions and tire replacements. They further the discussion by explaining the use of telematics (using both remote sensing and telecommunications to gather/analyze data) and GPS systems to better collect the information.The data can be used to ensure safe methods are being used when traveling on the road and that all packages get delivered at the appropriate time. The data collected isn’t just for safety reasons though. With the information found they can make their own maps that can measure the travel time, the shortest routes, and indicate the location of travel signs. All of this information is sent to a team of specialists so they can analyze the data to improve the company’s performance and maintain a stable, working company.

    The Geospatial Revolution made a huge change in the way we, as humans, can battle world hunger. The Geospatial Revolution has enabled us to use satellites, ground resources, and rainfall data to recognize patterns in crop production on a worldwide scale. Being able to map all this data would help us analyze agricultural problems on a worldwide scale. Also, satellites can help us recognize the amount of sun used for agricultural energy and would therefore help us predict crop outcomes with local droughts or floods. This is extremely useful for areas we can’t physically visit. A good example of these effects would be in Zimbabwe. In 2005, Zimbabwe was under a political crisis which wouldn’t allow us to collect any ground source information. On top of that, their crops weren’t faring too well due to a drought striking the area; luckily, thanks to the new methods available to use by the Geospatial Revolution, we were able to analyze patterns using historical food productions and successfully predict that 6-8 million people were going to be in need of food. Without the advancements of the Geospatial Revolution, those millions of people could may as well not be here today.

    Geospatial Revolution has made a big impact on Portland Oregon. Portland is the first city to implement GPS’s into their public transportation. Portland makes it so all of their citizens can view a map of the city so they know what to expect, traffic delays train delays etc… PDX reporter can help to let you know what is happening. 3D building is also possible. LI DAR or light detecting and ranging. A remote sensing system that uses pulsed laser light to capture the exact location or shape of a distant object in 3 dimensions. Geospatial technology saves money and helps with crime data and bus information. To make the 3D print of a city, a plane fly’s over the landscape using LI DAR and it beams down and the beam comes back up and it processes the data and turn into a 3D map for people to look at. With GIS they are able to do sightline evaluation. This helps to make sure a building does not block the view of mount which is against the building code. They can also use GIS to make sure a buildings shadow does not block a park and shows this in 3D. Geospatial Technology is changing our world in many ways and it saves money and will soon be the only thing we use for updates and building.
