In this weeks Data Search
lab we worked on downloading data from online sources, data
management, selecting graphic projections, and re-projecting data.
This lab allowed for a lot of creative freedom both in selection of
data and how that data was to be displayed. From the data required I
created two maps which ended up having an “invasive plant theme”
The Required “Public
Lands” data I downloaded was State Parks in Martin County. Then,
the two required environmental layer I downloaded were 1) Invasive
Plants and 2) Wetlands.
Because the invasive
plants and wetlands made the map overwhelming and unreadable I did a
definition query to limit my selections. The wetlands layer had water
sources other than wetlands so I preformed a definition query to
select “wetlands” in the “type” field. For invasive plants I
selected only the species melaluca, since melaluca have a drastic
effect on Florida’s wetlands. With this data I was able to create
two maps containing all of the required data. The first showing
melaleuca's encroachment on the State Parks in Martin County. The
second showing the proximity of malaleuca to wetlands in Martin
County. I really enjoyed this lab.
