Week 5 - Projections Part 1


For Week 5 of GIS lab, we dived into the world of Projections(Part 1)more importantly, projected coordinate systems and the characteristics of them. The PCS is important to consider because the maps that are viewed in ArcGIS are in in some type of PCS and they have differences. That difference can be the distortion, the way the map is placed, and also the size of the boundaries drawn.  In this lab we learn how to change the PCS or reprojecting shape files with the use of the geo processing tools and it as great practice for the second part of projections where we will expand more on PCS and specifics. The map above showcases the counties of Florida in three projected coordinate system and the area of select counties. Notice the slight chances in area among the counties due to the change in PCS.

GIS 4035L: Lab 4 - Spatial Enhancement

Image
 For Lab 4, Spatial Enhancement, we looked into learning how to work with Landsat 4-5 data form the official Glovis website and use ERDAS and ArcGIS Pro to run spatial enhancement tools on different image. The first and second exercise involved learning how to download and format data from the Glovis website. The third exercise involves using and manipulating image histograms for the LandSat data. The fourth and fifth exercise includes the use of Spatial Characteristics and Band Ratios to alter the band layers to make certain features pop out more than others. The sixth exercise involved examining the layer information of the image layers while the seventh exercise involved tying in all the exercises to now independently identify features with what was learned. Below shows 3 different maps showing a large river, lake, and snow cover features identified with spatial enhancement.

Week 12 - Georeferencing

Image
For week 12 of GIS lab and final week before the final project, we took a look and Georeferencing and Lidar. We use georeferencing to make control points and try to match the buildings with the aerial raster photos to get them as accurate as possible. With that we took the location of an eagle's nest and made a multi buffer layer with an given scenario. Also, we created a 3D elevation model with the use of Lidar data which was coverted to a DEM. The skills performed in this lab will be put to use in the final project. Not only will they be used in the final but even down the road as I build on my GIS knowledge. The maps above showase the use of georeferencing and Lidar data.
