Projections: Comparing County Areas Produced Using Various Map Projections

-

 



This week's lab highlighted small discrepancies that can occur when using various map projections that may lead to significant errors when performing spatial analysis. This map shows the state of Florida using three different projections: Albers Conical Equal Area, UTM Zone 16N, and Florida State Plane North. While visual differences between the three map frames may be negligible, the table displays the area in square miles for each of the four selected counties that were calculated using these different projections.

Isarithmic Mapping: Annual Precipitation in Washington State

-

The second most common type of thematic map behind the choropleth map is the isarithmic map. While choropleth maps are great for mapping phenomena existing within hard boundary lines, also known as enumeration units, isarithmic maps are perfect for mapping continuous data such as temperature, precipitation, or elevation. In isarithmic mapping, contour lines are frequently used to connect locations with equal values. Hypsometric tints can then be added to color the areas between contour lines with different shades so that map readers can easily distinguish between areas with high and low values.  In this lab, our task was to create an isarithmic map showing average annual rainfall in Washington State. This rainfall data was interpolated using the PRISM (Parameter-elevation Regressions on Independent Slopes Model) method developed by Oregon State University. The map below was created using ArcGIS Pro. Areas with low precipitation (less than 10 in/yr) are shown in red, and areas with the

Final Project: Bobwhite-Manatee Transmission Line Analysis

-
Image
The Bobwhite-Manatee transmission line is a 230kw line that connects Florida Power & Light’s (FPL) Manatee Energy Center in Manatee County with a substation about 3 miles south of the Manatee-Sarasota County border. Although this transmission line has already been installed, for the purpose of this assignment we assumed this project was still being planned.  Our task was to use ArcGIS Pro to analyze FPL’s proposed location based on four primary objectives identified in a survey conducted by FPL: (1) environmental impacts, (2) number of homes and parcels affected, (3) number of schools and daycares affected, and (4) total length and cost. The final project incorporated many of the processes and concepts we have been working with throughout the course.  Below are my map outputs for this assignment.

Development Suitability Analysis

-

For one of the scenarios in this week's lab, I was playing the role of a GIS Analyst for a property developer. My task was to create a map showing suitable land for development based on the following criteria:  Land Cover Soils Slopes Streams Roads  My general process for this analysis was to first convert all of these layers into rasters if they weren't already. For the rivers and roads layers, I used the Euclidean Distance tool to calculate the shortest distance from each cell to the nearest river or road. I then reclassified each of these layers based on a suitability scale of 1 - 5. Lastly, I combined the results of each of these five criteria using the Weighted Overlay tool. Below are my results.  The first map is an equally weighted average where each of the five criteria have an influence of 20% (or 1/5th). The second map shows an alternatively weighted output where each of the five criteria were weighed as follows:  Land cover (20%)  Soils (20%) Slope (40%) Distance to
