Module 5b - Intro to ERDAS Imagine and Digital Data

There was not a map deliverable for this lab, but in exercise 4 we created a map that showed the percent area of the most erosive soils. This exercise reminded me of previous tasks I have completed with ArcMap, but it seemed to be an easier process. I can appreciate how this function will be useful for many different data types including stand type, population density, and other trends that can be uncovered by using formulas to select specific characteristics.

Module 2 - Visual Interpretation

This week, we were tasked with identifying different features and elements of aerial photos in Arc Pro. This was my first time using arc pro extensively and it took quite a bit of patience to figure out how to navigate the program. Ultimately, I did complete my maps, but I will be use provided help from now on! The following information is from my process summary for future reference: Exercise 1 The objective of exercise 1 was to identify different textures and tones on an aerial raster image. I accomplished this by creating polygons that outlined distinguishable areas for each of these criteria including Tone: Very light, light, medium, dark very dark – and – Texture: Very fine, fine, mottled, coarse, very coarse.  This exercise caused me the most trouble because I had never used Arc Pro before. After adding my input files into the folder and reading the instructions and helpful tips from ESRI, I still could not figure out how to create a feature class. Finally af

Module 4 Lab: Cartographic Design

This week, we were asked to create a map that employed features that provide the maximum amount of legibility and clarity. Using Gestalt principles of perpetual organization, I was able to create a map that highlighted schools in Washington D.C. and separated them by elementary, middle, and high schools. Contrast: I used contrast to differentiate the schools by color and size Visual Hierarchy:  To implement visual hierarchy in my map, I ensured that the focal area, Ward 7, was the main point of the map by making it a lighter color than its surroundings and its features more prominent than those in other areas. Next, I made the title, subtitle, and legend the second most important features on the map by their locations, colors, and size. The scale and north arrow, data source, and frame and neatlines are the next most-relevant features, respectively. Figure-ground Relationship: To establish this, I made Ward 7 lighter than the other features on the map to make it appear close
