For this weeks lab we produced four
different maps using the same data. Each map showed a different
characteristic – Hill shape, Slope, Aspect and a 3D render of the
particular area we were working with.
The potential of this lab work is shown
by the amount of extrapolated data that can be taken from just one
data source. With this lab we were given one set of data and produced
four different maps all of which displaying different aspects –
hill shape, slope, aspect and a 3D model. This illustrated that
ArcGIS has once again proven to be a very powerful analysis tool.
Layering, selecting different colours and editing the map to make it
presentable was fairly easy. Its also easy to see the real world
application of this task which made it more enjoyable to complete.
Finally, this task was, I feel the first time I felt like I knew what
I was doing and what each step would produce before I completed it.
The consequences and pitfalls to this
task are that if you didn’t have previous experience with ArcGIS
then this task would be very difficult. Furthermore, as I mentioned
earlier the data has come from one source which may be inaccurate –
meaning that the four maps that I produced could be inaccurate. To
counteract that problem you could compare the data to other data
sources. Finally, the data was sourced for us, and we didn’t have a
chance to find an area to work on that we knew meaning that there
wasn’t as much of a personal touch to the task in comparison to
others. Even so it was an enjoyable task.
