ArcGIS Desktop part 28 (analyzing feature relationships 7: buffering features) Video Lecture | Way to Learning GIS and ArcGIS - Data & Analytics

welcome everyone to exercise number 12 a
in yeah let me say it like this maybe
you have asked yourself how to create
some kind of zone around your point or
how to determine a special distance
around your points or around a polyline
polylines and in this exercise number 12
we will concentrate on answering this
question how to create a buffer zone in
this example here we are still
confronted with a problem that some
company would like to have some trees
here in this polygonal area but they
have to keep in mind that there is a
special distance around these nests
located here and also around the streams
where they are not allowed to cut some
trees and therefore we will go to or we
will go and create new features which
will represent these forbidden zones and
in the end we will come up with an area
where they can harvest the trees so what
we will need there for is something like
a buffer tool you can try to find it
here on geoprocessing but there's also
the possibility to go over the tool box
using the analyst tools and analysis
tools then there's something like a
proximity analysis and you will find the
buffer tool there as well there are some
other things here available but we will
stick with the buffer tool we'll start
with creating a buffer zone around the
bird's nest which we'll cover in an area
of about 800 meters so the input feature
for this exercise is quite easy to see
this nests F which has been the result
of some I think extraction method we
have or i've presented and i think the
loss or the law the video before the
last one and yeah so this is a result
from the last
so sizes and we have a new output
feature class this is called here nests
F underscore buffer which is located in
the geo database I haven't used before
so I have to check that check this again
we need to use a geo database from
chapter 12 go to data there's a Tungus m
DB
and you'll same as nests f1 s F buffer
you can see here that there is already a
polygonal feature available in the data
this has been to the upcoming upcoming
exercises so we will save that and we
will create buffer zone of about 800
meters around each of these nests you
can also specify a future we will do
that later on with the streams but as
you can see you can specify field which
gives you the distance and so the buffer
can be very very specific around your
features what else is to be chosen and
there's a dissolve types of there some
oo if there will be some overlapping
around these some or in these polygonal
features on this rings we will create
you can decide whether they should be
dissolved like all or none like they
should not be dissolved you can see on
each of these elements here some kind of
to help there's also the tool help which
is the entire help function here so up
there it is so you can easily see what
the result will look like if you would
dissolve types or or none or something
like else regarding the input so this is
it
so we'll just press ok
the function is executed and we'll have
to click up to the results of the
geoprocessing it's still working still
need some time I think we are nearly
finished here there it is there's output
feature we will add this to display and
as you can see here there should be only
two polynomial features no there's just
one polygon your features which is quite
fine for the moment so this is it these
areas are prohibited for cutting trees
what else will we do now we will
concentrate on the streams and we'll
still use the buffer tool for that input
features now is streams off the output
needs to be adjusted as well so streams
have underscore buffer now I have to use
the color school use this and we will
use a field which is called distance and
due to the fact that this is a polyline
feature you can decide whether there
should be a full range around the
polyline like on the end of the polyline
there's a vertex and you can create an
half circle around the vertex or you can
decide whether there should be just a
half circle on the left side the right
side on outside only so um this is it as
well oh no the site type was for these
sides of the poly poly line the end type
was for the for this vertex at the ends
and there's still lead the sole function
we won't use any desolvation vidura to
dissolve in the moment so just press ok
still booking and we will add this to
this play as well and as you can see
here depending on the fish type there
are differences some will choose that I
would like to create on or would like to
choose only no this was wrong streams
buffer
so now can select only these dreams as
you can see here so I can create a
rectangle and nothing will be selected
now I have selected this one and would
like to see the attributes or for that
so one of our one out of 358 is selected
as forming yes so the buffer distance is
100 and in this one a spawning knows so
the buffer distance is 50 so this is it
for the moment thank you for watching
take care and good bye I hope that's it
for the exercise yes so stay tuned for
next exercise 12b see you later part
