Pleases watching geospatial revolution video and summarize what is the main idea?
Welcome to the geospatial revolution
In a world
Where everybody’s texting
Geospatial technology is critical to understanding
What’s happening at a particular location.
-It’s the speed of the internet.
It’s the capability of remote sensing satellites.
It’s software like Google Earth.
Taken altogether, you have an explosion in the way we view the Earth.
-Everybody’s somewhere, everything’s someplace, and a map is a way of organizing all of that information.
-It’s information from aircraft, from satellites
It’s can be a collection of information from a tower that you’ve set up.
-we’ve been using maps for hundreds of years to know where we are.
Now that nice lady tells me which way to turn.
Turn right then turn left.
-Virtually all of the information that you’re sharing with anybody these days has some kind of geospatial tap on it.
-It’s really the human element.
There’s basically this entire information ecosystem that we have access to now.
-I can receive information.
-I can transmit information.
-I can broadcast my location.
And that is revolutionary.
-It’s mamazing. It’s cutting-edge.
It’s----well, changing the world.
HOW WE GET THERE
-In 1/10 mile, turn right at stopsign.
-Some people will call this a GIS.
It’s not.
It’s GIS receiver.
It’s, I think it’s fair to say, a miracle of science and technology.
It’s able to collect signals from global positioning satellites far up in space.
-Each one of them is, every moment of every day,
Saying, “This is the location that I’m at in orbit around the Earth.”
If you know where you are with respect to three satellite points, you can use mathematics to determine where you must be on the face of the Earth.
-There are million of coordinates encoded in this box.
-Recalculating.
-And it can take those coordinates and render a map on the screen for you.
-Turn left on Whitehall Road.
Then turn left in 0.3 miles.
-Where do all those coordinates come from?
Where do those streets come from?
Lots and lots of people driving special cars continuously up and down every single road and digitizing those roads into a database that then can be downloaded into this little box.

How we got here
-There’s nothing new about mapping .can imaging without being able to talk, somebody showing where you’re going and drew a lime showing where the river is and an x where they are now and an x they’re gonna go.
-viewing the earth has really been based on technology.
The baby lonians etched the lay of the land on clay tablets in 2300 b.c.
And then in the 15th century, with the advent of printing, they started making maps.
Using wooden blocks.
-surveyoys would map by making measurements in front of them to a reference point and then
Back behind to the referoce point they had just passed
