Transcripts
hey watch this I'm about to blow your
mind you know sometimes you're sitting
around and you're like I kind of want a
burrito the size of my face and then you
get in your car and you look up the
closest Chipotle and then this little
device tells you exactly where it is how
are you not falling out of your seat
right now like that's astonishing so the
question is how does this thing know
where my burrito is but more to the
point for AP Human Geography how does
all the geographic information on any
map get collected you have to know the
answer to that question for AP Human
Geography unit once so if you're ready
to get them brain cows milked well let's
get to it so they're essentially two
entities that care enough to gather
Geographic data oh by the way if you
want note guys to follow along with this
video so that all the information finds
at home deep in your brain Falls well
then check the link below anyway first
individuals gather Geographic data so
maybe that individual is a researcher
and is trying to plot the spatial spread
of disease so the plans and policies can
create it to stop the spread remember
our boy Jon Snow from the last video
yeah that's exactly what he did with the
spread of Cholera in London or maybe the
individual is a community advocate
Gathering data about traffic patterns at
a local intersection so that people
don't get in as many accidents that
regardless these individuals often
record their Geographic data in the form
of field observations which is when a
researcher or geographer physically
visits the location and makes written
observations about what they see so they
might write an account or take
photographs or interview residents of
that location to gather information
through questionnaire and then in
addition to field observations
Geographic data can be gathered through
travel narratives which are written
accounts of a person's travel for
example our boy IBN batuta who was a
Muslim scholar and Explorer in the 14th
century and he covered a metric butt
load of land in his various travels I
mean the guy traveled something like 75
000 miles in his lifetime to which I say
anyway his travel narrative was packed
with Geographic and cultural
observations that had significant
effects on map making during that period
and Beyond or in some cases media
reports can be good sources of
geographic data as well the media often
show up to locations to tell stories
which include details of the people
living there and the geographic location
in which they live and geographers are
like well that's nice I'll take that
okay now the second kind of entity that
is concerned together Geographic data
are organizations and they can be
businesses or government agencies or
whatever and these organizations tend to
have much larger budgets so they can
gather data at a much larger scale than
the Schmo out in the field with his
notebook writing field observation if I
pull up Google Maps they tell me how
much traffic is on the way like what
kind of freaky witchcraft is this like
how do they know well people have been
using Google Maps for a long time and
every time anyone uses it Google is
collecting data about where they go and
what they do how about the traffic was
Etc daddy Google is always watching but
I got to admit I hardly mind because you
know this is real useful but also
governments collect Geographic data for
their own purpose for example here in
the United States every 10 years the
government takes a census which gathers
all kinds of information about its
citizens like where they live how old
they are what religion they practice at
seven and then all that data is used to
make decisions about policies to pass or
how to allocate representatives in
Congress because more or less people in
an area means more or less
Representatives okay now real quick when
it comes to data there are two terms
that you're going to see hurled around
and you got to know what they mean so
quantitative data is numbers based
information it's about counting things
like there are 400 houses in that
neighborhood or there are five million
people that live in that City whatever
qualitative data describes the
characteristics or the qualities of that
data so qualitative data won't tell you
how many houses are in this neighborhood
but it could tell you how the residents
feel satisfied or unsatisfied about
living in a neighborhood with that many
houses so quantitative County County
qualitative feely field and now let's
turn the corner and talk about the
methods used for Gathering Geographic
data now I've already mentioned a couple
methods like field observations and
media reports and travel narratives but
here we're going to consider the big
boys namely geospatial technology this
is a blanket term for all the hardware
and software that can examine and
measure geographical features on the
earth so first you have global
positioning system known by its nastier
name gpn that's what you see on Google
Maps GPS is a collaboration with my
device and a network of U.S government
satellites that orbit the earth twice
daily so by communicating with at least
four of those satellites they can tell
me exactly where I am or my absolute
location and the absolute location of
the Chipotle and then tell me how to get
there okay the second geospatial
technology you need to know is called
geographic information systems or GIS
and this is software which can
manipulate Geo spatial data that can be
used for research or problem solving now
don't get confused between GPS and GIS
GPS is used for determining location but
GIS is technology for analyzing data for
the purpose of answering research-based
questions so for example GIS software
can produce a map showing the spatial
distribution of factories that dump
nasty pollution into the environment and
then compare it to the location of
environmentally sensitive areas like
Wetlands but this kind of analysis isn't
just reserved for the researchers thanks
to the rise of various online mapping
platforms non-scholarly rabble like you
and me can access all this data and
answer our own questions okay it's a
third geospatial technology you need to
know is called remote sensing and this
can be done in two ways first remote
sensing can gather geographic
information through satellite imagery
which can help visualize population
patterns and other geospatial
information for example look at this
image of North and South Korea at night
lots of Lights in South Korea but North
Korea not so much Kim likes it and that
image can tell you a lot about the
wealth and different levels of
development in each place but also
remote sensing can be done with aerial
photography for places that need more
detailed information gathered like major
cities
can I have a burrito the size of my face
would you like walk on it obviously and
so because of all that Geographic data
I'm about to crush this burrito all
right click here to keep reviewing unit
one and click down here to get the note
guides to follow along with every dang
video of the whole course I mean don't
tell anyone but if you're not really
into reading your textbook then these
notes are going to help you get
everything you need to do well in this
course all right I'll catch you on the
flip-flop I'm Laura
