ERDAS Imagine and Digital Data

-

 


This week in GIS4035, we were introduced to ERDAS Imagine. It seems to have a lot in common with ArcGIS Pro and I am sure I will learn a great deal about it in the coming weeks.

The map we created depicts the different land cover classifications of a small area of raster imagery. My son is sitting on my lap as I write this. He asked why is it all blocks and, in a way, I think that question encapsulates this week's lesson. I explained to him, each block (pixel) represents a block just like Minecraft. Each block can only be one thing: dirt, rock, grass, etc. The more blocks you have, the more you can build. The higher the radiometric value, the more we can build!

My name is Kelsey Yoder-Ostroski and I am a new(er) student in the world of GIS. This is my third class in UWF's GIS Admin graduate program as a full-time student. At the moment I am a caregiver to our kids but I also do volunteer work with a nonprofit providing support to local moms. We are a military family; we have lived in the Navarre area for 3 years and are preparing to move to Germany this summer. I'm not ready for the cold! I am originally from Texas so I love the heat, but we can't wait to see everything Germany and its neighbors have to offer.  In my free time, I enjoy learning German, baking (mostly breads), or doing home improvement projects. I have a weakness for cookies and power tools.  I am pursuing a master's in GIS business administration because I love how applicable and versatile it is. It literally encompasses every topic on Earth from the land to its resources and to all of history. I'm not 100% sure what I will do after graduating but I am int...

Coastal Flooding & Storm Surge Analysis

-

     As climate change continues to intensify storms and increase flooding, it is vital for communities and governments to prepare for inevitable storm damage. In this week's lab, we explored coastal flooding models and prepared our own storm surge analysis. Our study area was Mantoloking, New Jersey, a low-laying barrier island that suffered major damage from superstorm Sandy in 2012. More information about the storm can be found on New Jersey's Department of Environmental Protection . Superstorm Sandy     By comparing LiDAR data before and a few days after the storm, we can create a comparison analysis. The LiDAR data is converted into a DEM by first creating a TIN (triangulated irregulated network). As the TIN shows, the topography varies little with only very mild sloping.  LiDAR .las point cloud dataset is converted into a  TIN       By subtracting the two DEMS, we can see the changes in the environment. Further color manipulat...

Introduction to Python

As an introduction to Python, which is a computing language that is embedded in ArcGIS Pro, we were tasked with creating a flow chart and pseudocode for converting radians into degrees. Flowcharts are a visual method of planning, which is an especially important process to complete before delving into complicated code. Flowchart created in iodraw.com The aim of this exercise was to introduce us to calling up IDLE and ArcGIS Notebooks. IDLE looks like the stereotypical coding interface with its intimating emptiness and blocky text; whereas Notebooks is nearly the opposite with its bright, white interface, menu options, and bubbly outlining. Both programs act as language interpreters for the Python coding language, converting user commands into binary which is then read and executed by the computer processing system.
