Raster and Vector Maps this project will take advantage of understanding the differences between raster and vector maps and analysis of layers. 1. Using the OLIVER Interactive GIS tool add the following raster and vector layers: Raster File 2019 Color Ortho image (USGS) – found within the Images/Aerial Photos (Ortho Imagery) folder Vector Files Census 2010 Environmental Justice Populations – found within the Census 2010/Environmental Justice Populations folder Farmers Markets – found within the Infrastructure/Farmers Market folder 2. Search by address by typing Boston, MA and zoom into this region. Note that the Census data is represented by polygonal features to describe specific entities, highlighted by color. Also note that the farmers markets are distinguished by two types (seasonal or winter markets). Notice the vast difference in the amount of seasonal farmers markets to winter famers markets (depending on the sequence in which you added your maps, you may have to move the farmers markets layer to the top so that they can be seen). This could be an issue when considering access do minorities during the winter. Here’s a sample of the map I produced: Within your report 3. Describe the differences between the different maps and their advantages and disadvantages. 4. Describe (in your own words) the main issues that need to be considered when you want to obtain raster and vector data. 5. Analyze the differences (along a transportation route, distance between each, etc) to consider a decision to establish additional winter locations across the region to support the minority areas (these are the areas highlighted in yellow). 6. Explain your rationale, how many additional winter markets, plan for sustaining new locations (sustained trucked in shipments from larger agricultural areas, greenhouses within the city), etc.
