Content
 The following slides contain flow charts for the GIS steps and GIS maps at the end.
 Flow charts:
 Waterways Maps:
 Main roads -Mask
 Slope -size of area
 Reclassify -my area
 Extract by mask -basemap with characteristic (zoom in)
 Clip -climate (rainfall and temperature)
-population
-vegetation and a trip through time regarding
vegetation

Description of
site and problem
The study area lies at the norder border
of Carrasco national park Bolivia. This
area is inhabited. The main activities of
the locals are agriculture and timber. The
thing that makes this a problem is that
the activities are shifting into the the
national park. As example you can see
that the main roads don’t stop at the
border (purple line in the image) of the
national park.

 In my are there are 2
villages, Israel and villa
Zabala. I’ve selected all
towns and cities from
the places shapefile.
After that I calculated
the distances to these
towns and cities using
allocation. I than
selected the relevant
colums and the result is
my_places_pointDistanc
e1 on this slide and the
next one.

This is how it was
back in 1970. It
can be observed
that even then
there were
activities in the
area. That can be
seen by different
types of green in
the area, patterns
and rectangular
shapes. All of the
above means
different types of
vegetation

 Not the best satellite photo.
Nonetheless changes can be
observed. The patterns
around the river have
become smaller. Almost
seems like there is less
activity in the area and
recovery of vegetation. But
in the north (the white
polygon) there are
activities. The vegetation
there is less dense and
open.

 There are new developments
to be seen. A road (the red
line) can clearly be seen
going from north to the south
west. The yellow polygons
show signs of activities. The
vegetation is less dense in
these areas than in the
south. It seems open in these
areas or very short bushes.

 If there were any doubts,
this image proves it.
Fragmentations can be
seen and other shapes
with short bushes. The
activity in the area is
more. It seems there are
grasslands. Different roads
can be seen. The dark
green color (dense, high
forest) is getting less and
is moving south. The
vegetation on the river
sides is also dense

 Quiet interesting is to see
that the changes are not
only in the white circle. The
rivers are expending in and
out of the area. There are
multiple roads in and out
the area. More open
patches, more colors can be
seen. Dense forest, open
land and short bushes. The
activities are moving to the
south. The dense dark green
in the circle is left alone.
Probably because of the
elevation.

Types of vegetation
• High dense forest
• Forest edges
• Grass lands
• Open/no vegetation
• Recovering
vegetation/ short
bushes

Population
 More activities means more people in the area. As you may have noticed in
the previous slides, everything is moving to the south. There is were the
border of Carrasco national park is. This means that the pressure is getting
higher and higher on the park.
 The next slide give an overview of population (in rasters) of the area. There,
one may observe that the less populated areas (darkest rasters) are the
highest (probably very steep) and the river area. The elevation map in the
slide 21 shows that the south is indeed the highest.

Population

Climate in ‘my
area’. I’ve used
annual mean
temperature
and annual
precipitation. As
it is shown the
temperature
throughout the
year doesn’t
differ much. It’s
colder in the
south, the
higher places,.

This slide show the
rainfall in the area.

Conclusion
 The output of this assignment was used in our project. For example, the
elevation was a deciding factor in choosing solutions for the problems in the
area.
 It is clear that you have to think about all of the maps above when deciding
what to do. It’s like a puzzle. If one is left out it cause problems for
activities. You need all pieces.
