GIS 5100 LAB 6 Blog Post #1

 

Discussing the process to create a suitability analysis, I first began with the reclassification of the landcover layer using the Reclassification geoprocessing tool and specifying the suitability rating coinciding with the values for each land cover category. Once the first layer was completed, I moved on to the elevation layer, where I first had to find the slope before reclassifying it using the same parameters as discussed for the landcover layer. Again, I followed the same reclassification steps for the following layers: soil, roads and rivers, but I used the Slope geoprocessing tool to create a raster DEM and the Euclidean Distance Tool to establish cell values, respectively. Once the layers were reclassified, I began on the Weighted Overlay using the geoprocessing tool. I started the first analysis using a Weighted Overlay of 20% across the board for all 5 categories. The second analysis using Weighted Overlay was different, land cover was 20%, soils were 20%, slope was %40 and rivers and roads were 10%. Finally, for the sake of ease of comparison, I created a layout showing both Weighted Overlays stacked along with a legend.

About Me

I joined the Master's of GIS Administration at University of West Florida because of my desire to pursue a career path heavily centered around GIS. I took an Intro to GIS course during undergrad, and I use it heavily in my professional life. The University of West Florida's program is the perfect fit because I can still work full time, and go to school full time. When I complete this program, I am going to either pursue a career as a GIS Manager at a public, research-based entity or continue my way through academia. Whatever my decision, I know I'll have a solid and unique skillset to bring to any position.  My Story Map Link

The objectives of this week's lab were focused on cartographic design in ArcGIS Pro, applying map design principles, explaining design choices based on an audience, and applying different typographic styles, including placement, to achieve legibility, visual contrast and hierarchy. Looking the attached map, I believe I achieved the five map design principles represented in my map.  Map one: I addressed the map principles of figure-ground organization and visual contrast by choosing a darker color to represent Travis County, and brighter, lighter colors to represent the individual layers. I achieved legibility by choosing a legible font in black text, and sticking with the same font/color for the entire map. Lastly, I achieved hierarchical organization and balance by placing the features like recreation centers on top of features like the County, water bodies and roads, which centering Travis County with a landscape template in the center of the paper. Map three: I used text (type, ...

I chose to use the USA Contiguous Lamber Conformal Conic coordinate system for the State of Ohio. I had chosen this one over coordinate systems that I compared like WGS 1984 UTM Zone 18N and NAD 1983 StatePlane Ohio North and NAD 1983 StatePlane Ohio South. The reason I chose the USA Contiguous Lamber Conformal Conic System was because I felt it best represented Ohio as a whole, rather than Northern or Southern Ohio.
