GIS 5100 - Suitability Analysis

 Module 6 is here! For the 6th and final module students have been tasked with creating two blog posts. This is my first blog post for this module and the focus is Suitability Analysis. We were tasked with creating a suitability map which models and rates the best locations for development. To do this we had to take into consideration criteria that best determines suitable locations for development. As such, the following are the criteria:

Criteria 1: Landcover best suited for development, such as agricultural or meadows.

Criteria 2: Soil best suited for development.

Criteria 3: Gentle slopes .

Criteria 4: Areas more than 1000 ft away from streams.

Criteria 5: Areas that are near to roads. 

For each of the above criteria rasters were ranked or created then ranked via reclassification. This step was followed by performing a weighted overlay analysis, which combined the criteria at various weights to determine the most suitable areas for development. The weighted analysis was performed twice. The first time all criteria had equal weights of 20 percent. The second time the criteria weight was as follows: Land cover 20%, Soils 20%, Slope 40%, Distance to streams 10% and Distance to roads 10%. The results from the analysis are displayed in the map below.

GIS 5935 - Surfaces - TINs and DEMs

Image
Having moved on from the modules regarding data quality, this week we were introduced to surfaces and surface models, more specifically Triangulated Irregular Networks (TINs) and Demographic Elevation Models (DEMs). TINs are based on vector data and are made up of a series of linked triangles that vary in shape and size, but display a 3D representation of a surface. DEMs are based on raster data, more specifically the spot heights associated with each grid part of a raster.  For this lab we were tasked with creating a TIN and DEM, as well as displaying contours based on both of them. We were then tasked with comparing the contours produced by both. Below I have included images of my results.  (a) Contour lines based on the TIN (b) Contour lines based on the DEM The contours produced as a result of the TIN appear to be more jagged, while the contours produced from the DEM have a smoother appearance. There is also a noticeable difference between the derived contours in areas...

GIS 5935 - Data Quality Assessment

Image
Like the second assignment, this module continues to focus on data quality. More specifically, this week focused on data quality of road networks. As such, we were tasked with performing a comparative assessment to determine the completeness of a street centerline shapefile and a Topologically Integrated Geographic Encoding and Referencing (TIGER) road shapefile for Jackson County, Oregon.  To perform this assessment we utilized a non standard method, based on that used by M. Haklay in the "Comparative Study of OpenStreetMap and Ordinance Survey datasets" in 2010. This included using a grid, which encompasses the study area, to clip the road network into smaller sections. These smaller sections give more detailed insight into areas which may be considered complete or incomplete. Once the roads were clipped to each grid cell/section the lengths were calculated and then compared.  My analysis determined that 134 of the grid cells/sections contained parts of the street cente...

GIS 5100 - Coastal Flooding

Image
During this week's module, module 4, we learned about Coastal Flooding, which can take place at various speeds, including rapidly via surge or slowly via sea level rise. This week we were tasked with performing analysis on the New Jersey shoreline and the coast of Collier County in Florida. In New Jersey we used LiDAR data to evaluate change post hurricane Sandy. This analysis included observing the raw LiDAR data, followed by the creation of Digital Elevation Models (DEMs) of pre and post hurricane Sandy for comparison. A more recent building vector file was also used to assist in the assessment of change, although using more recent data should be used with caution as it does not always accurately depict change as a result of a disaster event. This is particularly true as more time passes. The following map displays elevation change on the New Jersey Shoreline.  Map depicting elevation change post hurricane Sandy.   For Collier County, Florida, we were tasked with determ...
