When comparing the reference point to the average point that we calculated, both the horizontal and the vertical accuracy are about six meters off of the reference point which would put both in the 68% Precision Estimate. The only bias I could think of would be that when people went to go out and collect the waypoints they wanted to try to stay away from the buildings close by so that could be why they were moved over by about six meters on average.

Horizontal accuracy is calculated by using a measuring tool on a program like ArcGIS Pro in order to find out the distance between two points. The precision is measured by using whatever percentage you are looking for, for example 50%, and multiplying it by the total amount of values you have. If you get a whole number from that then you average the value at the number with the value of the number after it and you are given your percentile. If the number does not come out to a whole number then you would round up to the nearest whole number and then just use the value that corresponds to that number.

First I created a raster from the roads shapefile. I then reclassified that raster as well as the elevation and landcover rasters according to the guidelines given. Then I did the weighted overlay giving 60 percent to landcover and 20 percent to the other two layers. I then inverted the model by using the minus tool and subtracted it from ten. I then created distance cost models using the two polygons given. Then using those two layers I created my corridor file which I then resymbolized to show only the best possible routes for the black bears to take.

One factor that I would love to be able to add to this analysis would be if there are any wildlife crossings nearby enough that would make it worth it to reroute the corridor. If there is that that could drastically change the corridor in order to make sure the black bears are protected on their path.

 

GIS Applications Lab 6 Module 6 Part 1

In the first half of the lab this week we learned about how to use Boolean expressions to analyze areas that would be suitable habitats for panthers and suitable land for a property developer. The layout I attached above shows two maps, one map has an equal overlay of the five areas we were looking at (roads, rivers, land slope, landcover, and soils) while the other one puts more importance into slope. For both maps the most ideal locations are in dark green while the less ideal areas are in dark red. I have really enjoyed this lab so far because we are learning about all the different ways GIS can be utilized and it makes me excited for my future career in the field.

In order to determine the damage assessment these are the steps I would take to determine the level. First I would zoom into an extent to where I could see the property well. I would look to see if the structure was damaged and then how much. I would then look for wind damage and inundation. Then finally I would try to determine what the building was.

These are my final results in terms of level of damage in relation to distance from the coastline.
