Lab 2

For our 2nd lab we went to the Ocmulgee River and did different experiments.  One of the experiments we did there was to measure the flow rate of the river at different depths.  We accomplished this by having a floating object and a stop watch to measure the distance traveled over time which gives a velocity.  Our results was that the deeper water had a slow but steady flow rate but the shallow water was literally stand still as our object barely moved forward at all.  Another experiment we did was to measure the amount of clams at different locations in the river.  We found out that in the deeper water the clams were more prominent compared to shallower water.  Along the shore also the clams were rarer than out in the deeper water.  The finals experiment we did  was to measure the difference in the elevation along the river bed.  We used two sticks with premarked lengths and a string attached between them to have a constant to go with the length.  This is the graph we created to show the difference between the width of the river and the depth.  The average depth of the trials was 19.8.

Isopleth

This type of map relies on contour lines to represent boundaries and amounts which is most represented by terrain or weather maps.  The lines of the boundary highly matter and show the exact estimated area of measurement.  

Proportional Symbol Map

This style of map has symbols associated with some measurement and the larger the size of the symbol corresponds to the amount that was measured.  The position of the symbol matters but not necessarily the boundary as the size might not represent the correct area but the correct amount in some cases.

Dot Density

In this type of map, dots represent are certain amount represented in the map key.  The location of where the dots are placed in the area are irrelevant as it is an aggregate style map.  

Chloropleth

This type is a population style based map where the amount measured is shown through different colors or shades on the map.  This is useful when trying to convey a large amount of some constant by showing it in proportion to several other similar areas mapped accordingly.
