Module 3: Intro to ERDAS Imagine and Digital Data

Module 3: Intro to ERDAS Imagine and Digital Data


Module 3 was in two parts. First part had us calculating wavelength, frequency, and energy of EMR, and the basics of ERDAS Imagine. 

Second part had us delve more into ERDAS Imagine.

Overall I only really struggled with the various calculations but math has never been my strongest subject.

The GIS industry I am most interested in is Emergency Management. 

I watched the interview with Richard Butgereit with FDEM and watched ArcGIS Solutions: Emergency Management from the 2023 UC Sessions.

The three important things from the interview is, first, how much work goes into Hurricane Season in the off season so we are prepared before the storms so we can deploy resources as soon as they’re needed with, hopefully, no issues.

Second is that not every place has a dedicated GIS department. Like, currently, where I am, they are a small rural area, with a small local team. So after the storm hit, the state sent an emergency management team so they can run the initial response which sometimes includes GIS personnel if the area doesn’t have any or enough.

Third, I think this interview was recorded in or near 2015. But he touched on getting paid vs volunteering. FDEM/FEMA has improved its system in the last few years and the requesting resources and getting them paid for has greatly improved. If the resource is not available locally or in the state, the state can request people from outside of the state. If you are deployed, you should be getting paid for it - don't go anywhere without a mission number!

The three things I found most interesting from the Session is that across the nation the cost, size, and frequency of incidents are increasing, and Emergency Management is having to support more types of incidents than they ever had before, for example, the Pandemic response. With all these factors increasing, being able to communicate efficiently and effectively has also become more complex with all the various forms of social media and communication avenues. Being able to keep a consistent message and information across all communication platforms has been a challenge. 

Unfortunately my internship plans changed and I have had to switch to my backup plan of ESRI classes and prior hours. 

My approach to my LinkedIn was to try to cover the basics of everything that I am qualified in. Only highlighting one aspect of my qualifications would not represent my career goals well. The career I am going for requires various skills in GIS, IT, and Emergency Services.

Module 2: LULC Classification and Ground Truthing

 Module 2: LULC Classification and Ground Truthing


Module 2 had us learning about Land Use and Land Cover Classification and Ground Truthing. 

We created a land use/land cover map of a section of Pascagoula Mississippi and measured our accuracy using Google Street View. 

I really had to keep in mind to not to get lost in time with the details and forced myself to be create broader polygons. 

I made my classifications off of the ones provided in the lab.

Module 1 Lab: Visual Interpretation

Module 1 Lab: Visual Interpretation


First week of Photo Interpretation and Remote Sensing had us developing skills in identifying and classifying the tone and texture in aerial photographs, identifying features in an aerial photograph based on shape and size, shadow, pattern, and association, and interpreting features in true color and false color in infrared images. 

I did not struggle with any of the tools used in the lab.

I believe that I understood the material to appropriately label the required items.

Lab 5: M2.2 Interpolation

Lab 5: M2.2 Interpolation

Our labs on Surfaces continued on with Lab 5 with Interpolation with Thiessen Polygons, IDW, and Spline. 

Thiessen Polygons - as the name suggests - creates polygons between the sampling points.

IDW (Inverse Distance Weighting) - a DEM that gives weight to its nearest neighbors but can be "spotty".

Spline - DEM that smooths the differences between points. 






Lab 4: M 2.1 TINs and DEMs

Lab 4: M 2.1 TINs and DEMs


This week we started our labs on Surfaces. The first one being on TINs and DEMs. 

I was familiar with all the tools used from previous labs. 

We explored the difference between the TINs and DEMs elevation models and all their different attributes. One of the main differences between the two is that DEM looks more natural but TINs is more precise. 

It was interesting going through all the renders possible for the TIN layer. Finding the right combination of colors to show the different slopes, edges, and contours so they don't overwhelm each other was a bit of a task. 



GIS Job Search

GIS Job Search

This week we in our Internship class we had to perform a GIS Job search.

I started with a Google search, “GIS 911 jobs”, which led to Indeed. 

I started with these broad terms because I was already aware that the technical job names for what I am wanting varies across the nation. As expected, there were various different job titles – 911 GIS Technician, GIS Manager, CAD/E911 GIS System Administrator, 911 GIS Coordinator, etc. 

I went through quite a few of them and they all had about the same requirements. Most were completely dedicated to GIS tasks and a few mentioned working with IT. 

The closest I could find to what I am looking for was for Geographic Systems Administrator for a 911 center in Texas. 

The only requirement across the various job descriptions that I think I would struggle with at the start is SQL Servers, but once I learn the basics and get some hands on experience I think I would be fine. 

Ideally, I would want a role that is dedicated to GIS for 911 and assists with CAD/E911, IT, Dispatch Training, and GIS projects for Public Safety.
