GIS 335 Lab 5

GIS 335, Lab 5

Goals:

The goal of this lab is to use different geoprocessing tools to determine suitable habitats for Bears in Marquette County, Michigan. The lab will also teach some basic python scripting tools and model building.

Methods:
Part1:

First we need to create a shape file of bear location from the bear_locations_geog$ sheet. Right click the sheet and select create feature class from XY table. Make sure you save the file as a shape file and name it bear_locations. Next open up arc map and add all the feature classes within the bear_management_area dataset and your bear_locations shape file. Give the landcover symbology a unique color based on minor type. Then perform a intersect between bear_locations and landcover. Next perform a summation on minor type in the new attribute table to figure out the top three habitats.

Next you will create a new feature class from selection that only contains the top three habitats by performing a query in the landcover attribute table.

Now perform a buffer action on streams of 500 meters. We will use this buffer to intersect with bear locations to figure out which bears are with 500 meters of streams. You will figure out that over 70% of bears are within this distance.

We then combine all these to find a target area of bears yielding the total area suitable for bears. Then we will compare this to DNR management area by clipping the dnr first to the study area. Next intersect it with the total suitable area for bears. Then we perform a buffer of 5 km for urban areas in the landcover feature. Then perform an erase of the dnr intersect and buffer to get only the area managed by the dnr that lies in the bear habit area and is 5km away from urban area. You will have a map and data flow like this.

Part2: Section 1.
Next we will create a map to show areas in wisconsin to build new resorts. They must be on lakes that are 5 square miles and also not more than 10 miles from a city. We will use python for these actions.

This will produce a map that looks like this.

Part 2 section 2

We will create a map that will show potential for pollution levels near interstates. We will use a multiple ring buffer on the interstates from 1 to 6 miles away. You will use these python functions.

Then create a map that shows the levels ranging from high to low.
