Addison's GIS Journey

This part of the lab was an exercise to model the potential movement of black bears between two protected areas, creating a corridor. The given layers were reclassified using the tables given. The weighted overlay tool was used to combine the reclassified roads (20%), land cover (60%), and elevation (20%). A graduated symbology was chosen to show the higher habitat suitability implies lower travel cost. The raster calculator was then used to determine the cost surface. A corridor analysis was then used using Coronado1 as the source in the cost distance tool. Then Coronado2 was used as the destination with the rasters created from the cost distance tool. The corridor tool was then used and a new raster was created to show the best representation of the corridors.

 The first part of this lab focused on Boolean suitability in vector and raster. The goal was to create a suitability map modeling mountain lion habitat in Oregon. An elevation DEM was given and used to create a slope raster, then was reclassified into given suitability classes. The land cover feature was reclassified into given suitability classes. The soil polygon was converted to a raster then reclassified into given suitability classes. A distance to rivers raster was created and also reclassified. A distance to roads raster was created and also reclassified. The weighted overlay tool was then used and an equal influence between the 5 created rasters was used. The weighted overlay tool was then ran again with land cover at 20%, soils at 20%, slope at 40%, distance to rivers 10%, and distance to roads at 10%. The map layout below shows the results of the different weighted overlays.

 The lab this week focused on analyzing data, exploring the Marker Symbol Options, performing a raster mosaic, and locating and identifying attributes based on storm damage. A raster mosaic was created within the ArcGIS project and the provided rasters were added for pre and post storm. A domain was then created within the project with the following: inundation, structure damage, wind damage, and structure type. A new feature class was also created with the following fields: inundation, structure damage, wind damage, and structure type. The study area was then analyzed and point features were created based on the assessment. A coastline was then created and a buffer was used to examine patterns of damage in distances from the coastline.  Structure Damage Category Count of Structures 0-100 m from coastline Count of Structures 100-200 m from coastline Count of Structures 200-300 m from coastline No Damage 0 ...
