Lab 5 [GIS5050L]: Introduction to Projections

Created with ArcGIS Pro 2.2.0
The map above contains three data frames demonstrating three different projections of the State of Florida (Albers, UTM 16 N, and Florida State Plane 903 N). Four representative counties (Alachua, Escambia, Miami-Dade, and Polk) were selected for comparison of the associated impacts on area calculations.

 The table at the bottom of the image above demonstrates how area calculations for Escambia County were more closely aligned with the Albers area values given this county resides in UTM 16 N and State Plane 903 N. The remaining counties showed increasing distortion in area calculations given their locations either outside UTM 16, or State Plane 903 N, or both.

Lab 5 [GIS6105]: Tessellation

Image
  The final map I created in this lab includes some preliminary analysis of the differences in average dissolved oxygen levels as a side-by-side comparison for January 2014 versus February 2014. In this example I used graduated symbols colored red (dangerous level), yellow (warning level), and green (acceptable level). This provides visual cues on areas within Bayou Texar that may be at risk for water quality issues. A tessellated surface for this feature would be very useful to show the scope of the impact of the change in values from the northern to southern regions of this waterway. For example, for the results from January 2014, the tessellated cells colored near the northernmost site could provide guidance on how far in this area community groups could explore for potential contributing causes. Tessellated surfaces would also be beneficial for examining temperature-related data for this case study, as well as other environmental impact case studies where water temperature/qual...

Lab 5 [GIS5007]: Choropleth and Proportional Symbol Mapping

Image
This week's lab used both ArcGIS Pro and Adobe Illustrator to address a number of important considerations when designing maps, including the significance of using an appropriate projection (equal area) with choropleth map visualizations for population densities and factors to consider when selecting various classification schemes for data sets. For the data set above, the projection used is Europe Albers Equal Area Conic. This projection is particularly useful for choropleth mapping because it preserves area, which is critical when mapping densities. In this particular lab, we are mapping population density per unit area across European countries. Given this, it is critical to have a projection optimized at the continental scale so the unit area looks the same size across this region. To communicate the map theme, two different classification schemes are employed in this map, with classes selected to maximize overall contrast. This map uses the Quantile classification...

Final Project [GIS6005]: Conservation in the State of Florida: Preserving Key Habitats of the Striped Burrfish

Image
Striped burrfish are inshore fish known to exploit a wide range of depths. Although commonly found in grass beds around barrier islands in the Gulf of Mexico (Franks et al., 1972), they are also found near coral reefs (Robins, Ray, & Douglas, 1986), as well as in deeper waters during the winter months (Audubon Society, 2002). Changes to the geographic ranges of fish species due to factors such as ocean warming (Espino et al., 2019) are of concern to scientists. In addition, impacts to fish habitats in tourism-based states such as Florida are considered by economists given the socioeconomic benefits of commercial and recreational fishing to coastal communities (Lellis-Dibble, McGlynn, & Bigford, 2008). As one example of their impact, half of all federally managed fisheries in the U.S. depend on coral reefs (Burton, 2019). In addition, t he total value of coral reefs for southeast Florida was estimated in 2007 to be $174 million/year (Brander & van Beukering, 2013),...
