Module 3: Visibility Analysis

This week we were tasked to complete 4 Esri courses through ArcGIS Online. By passing the quizzes at the end of the courses the certificate was awarded. These exercises were intended to give us more knowledge on visibility analysis. The first course was Introduction to 3D Visualization and I learned navigate 3D scenes, manipulate height variables in a data visualization, how to convert a 2D map in to a 3D local scene, applying 3D symbology and applying realistic enhancements to local and global scenes. The second course was Performing Line of Sight Analysis where I used tools Construct Sight Lines, Line of Sight, and Add Z Information to see parade routes through a city to determine the lines of sight for observers and visibility between observer points and the parade route. The third course was Performing Viewshed Analysis, where I modeled new lighting in a campground. Tools to accomplish this were Viewshed, and we modified field values, and modeled the light coverage until the light coverage was improved. The fourth and last course was Sharing 3D Content from data in the city of Portland, Oregon. To accomplish this we displayed the 2D data as 3D layers, and converted the 2D data to 3D data using the Layer 3D to Feature Class and Feature to 3D By Attribute tools.

As you can see numerous tools were implemented and I learned a great deal from the Esri courses. They have so much information packed into not only the online portion, but the directions for the exercises are full of tips and tricks that I will use in the future. For instance, many items were manipulated in just the properties of the item. Tools were used here and there to accomplish tasks, however it was interesting to see more ways data can be changed using only the properties dialog box. Another trick I learned was in the symbology of 3D items and how to configure the properties to better reflect the environment, including sunlight shadows and the ways water can move.

Here are my resulting certificates to make this post more appealing to the eye.

GIS Portfolio

The final assignment in the GIS Certificate Program was to create a GIS Portfolio. It went as I expected. It is hard to write about yourself...
