GPS Map - Driving to School


View Larger Map This is a GPS map showing the route I took driving from my house to Bridgewater State University. I recorded my route using a smartphone app called My Tracks. The distance between each marker is 1 mile. The total distance was 16.8 miles.

St. Mary's Abbey Wind Turbine Project

For this project, I had to find all areas in Franklin, MA and Wrentham, MA where a wind turbine at St. Mary's Abbey in Franklin can be seen. The new wind turbine is 120 ft. tall. The map on the left shows all areas where all or portions of the wind turbine can be seen. This map shows results considering elevation only. The map on the right considers both elevation and the screening effect of trees. Some people may not be able to see the wind turbine if trees are blocking their view. I selected all areas that were labeled as forest or forested wetland and created a separate layer from that. I estimated the forest heights to be about 24 meters. I combined the forest layer with the DEM of Franklin and Wrentham to help create the results shown in the map. There are some flaws with this however. Some forests may have lower tree density or several different tree heights. So in some areas that are considered forested, the wind turbine might be seen in some areas. Below is a flowchart showing the steps I took to make both maps and also the layers and geoprocessing tools I used.

Massachusetts Community Colleges and Town Population

For this assignment, I had to locate all community colleges in Massachusetts using geocoding. Then I had to perform some kind of analysis. In my map, I show town population in the year 2000. Almost all of the community colleges are located in towns with higher populations in the area, and there are more colleges located in areas with the highest town populations. Some examples are explained in the map text.

Solar Wind Farm Project Maps


For this project, I had to find all suitable locations for a solar wind farm in Kingston, MA and a town of my choice (Pembroke, MA). The required selection criteria was that the site had to have a slope angle of 15 degrees or less, a southerly aspect slope (135 degrees to 225 degrees), and a wind speed of at least 5 m per second at a 30 m height. I also included land use in the criteria, where the land had to be described as either forest, waste disposal, or open space. I thought these three land use categories would be best for a solar wind farm location.Size of the the solar wind farm was not provided but should also be considered when choosing a location. I used several other raster and vector layers and geoproccessing/spatial analyst tools to come up with a final layer (shown in red on the map) that fits all 3 required criteria.

City of Brockton: New Industrial Park Project

For this project, I had to locate possible parcels for a new industrial park in Brockton, MA. In this report I included a map, a table, and a flow chart to show my steps in making the map. Map Description: This map is showing possible locations for a new industrial park in Brockton. The requirements were that the parcel must be at least 10 acres in area, at least 50 feet from wetland or water, and must already be zoned as industrial or commercial. In the map above the purple represents possible parcels where the new industrial park could be located. The gray represents parcels that are industrial or commercial. All purple parcels are zoned as industrial or commercial as well. A total of 14 parcels are selected as being a possible location for the industrial park. The parcels are labeled on the map and in a table. The table also includes the size of the parcel. Methods: I created this map in ArcMap, using data from MassGIS. From MassGIS, I downloaded a Brockton parcel layer, a zoning layer, and two hydrology layers. From the zoning layer, I selected all parcels that were categorized as industrial or commercial for general use. I created a new layer based on these results. From that new layer, I selected all parcels that are greater than or equal to 10 acres in area. I then created a new layer from those results. And from that layer, I selected the parcels that are at least 50 feet away from any water body or wetland. I created a new layer from those results, which are shown in purple on the map. These are the selected parcels to be a possible location for the new industrial park. Data Analysis: A total of 14 parcels are selected as possible locations for the new industrial park, based on the given criteria. However, the planning department may need to consider other site selection criteria. I was given the information that the parcel had to be at least 10 acres in area, but the projected industrial park size should be considered as well. How many buildings are there or will there be? How far apart will these buildings be from each other? If there is a plan for many buildings, then the larger of the selected parcels should be chosen. Location should also be considered. One of the criteria, was that the location had to be at least 50 feet from water or wetland. Other things should be considered, like if it is located along a major road, or close to a residential area. Also, the parcel should not already have an existing business on it. For example, the 3 parcels in the top left of the map are located where there is a mall. So, those parcels would not be suitable for a new industrial park. The parcel should probably be as far away from water or wetland as possible, in order to avoid any water contamination. The parcel along Belmont St. and Forest Ave would be a likely choice for the industrial park. It is not too close to any body of water, and appears to be in a location with no currently existing business. The parcels along the city boundary may not be the best choices if the planning department wants the park more within the city. The parcel near E. Ashland St. is close to a body of water, so that may not be the best choice. The 4 parcels on the right of the map may be good locations. Proximity to residential locations should be considered, because residents may not like the idea of living close to a large industrial or commercial park. If the only criteria would be to have the parcel be >= 10 acres, then there would be many more options. But you could possibly run into issues with conservation and other businesses. If doing this type of assignment with all Massachusetts towns, it would be best to work with all towns at once, instead of doing it one town at a time. That way it would require the same amount of steps. A way to make this map more convenient to use would be to put it into ArcGIS Online and share it or save it as a JPEG and upload it to a website or blog.
