Module 10 - Supervised Classification

Here is my Map for this week's assignment to use supervised clasification.   I am not thrilled with my results (notice all the white spots on the Distance inset) but we all have to start somewhere !

GIS4035 - Lab 9: Unsupervised Classification

GIS4035 - Lab 9: Unsupervised Classification

Here is my map for this week's lab about Unsupervised Classification.   In this lab we learned to work in both ArcGIS and ERDAS to classify and recode images to simplify data.

GIS4035 - Lab 8: Thermal & Multispectral Analysis

GIS4035 - Lab 8: Thermal & Multispectral Analysis

Here is my map for this week's assignment.   It shows how you can use ETM+ Thermal data to detect hotspots such as fires.   Also inclded a second view which backs up the termal data by showing the smoke generated by these fires.


You can see similar hotspots and smoke in the lower part of the map that I kept unlabeled so that you could see them more clearly.

Lab 6 - Spatial Enhancement

Lab 6 - Spatial Enhancement

This week's lab addressed the issue of removing (or minimizing) striping that may be present in Landsat Imagery.   This lab used tools by ERDAS and ESRI to performe these tasks.   You can see a highlight of what it looked like before and after on this map:

Lab 5a - Intro to ERDAS

Lab 5a - Intro to ERDAS

This week's lab introduced us to the ERDAS Imagine software.   This is a very powerful piece of sofware that we will use through the remainder of the course to better understand remote sensing.

This week we took some of the data we worked on in ERDAS, exported it out to ArcGIS and created this map.

Ground Truthing

Ground Truthing

This week, we took the data we collected last week and used Google Street view to "Ground Truth" it to perform an Accuracy Assessment.   On this map you will see where the green dots are, the Google Street view matched my classification.   The red dot indicate places where my map differed from what I saw in Google Street view.

GIS4035 Photo Interpretation and Remote Sensing Lab 3

Here is my map showing the Land Use and Classification of a study area.   This project taught me some good tools for data editing within ArcGIS.   This particular map only addresses Level I and Level II classifications.   It is easy to see how the complexity grows as you go deeper into subcategories....

Remote Sensing - Module 2 Lab

In this week's lab we had to create 2 maps.   The first map was a study in Tone and Texture.   You can see the different intensity levels in both tone and texture in this map:

 
The next map looked at identifying features based on shape/size, shadows, patterns, and associations.
