1 Forest Mean: 15078 std dev: 67,655 NAD 1983 Meters It is a vector dataset CEE 470/570 - GIS for Engineers Lab 1: Exploring ArcGIS Pro Question 1-1: What is the name of the Land Use area with the third highest value under total area? Question 1-2: What is the mean value of total area for Forested Wetland in Massachusetts? What is the standard deviation? Question 1-3: What is the name of the Projected Coordinate System (HINT: Projection) for your map? Question 1-4: What type of spatial dataset does SCHOOLS_PT represent – raster, vector, other?

2 It is a vector dataset Top: 957,378 m , Bottom: 780,156 m, Left: 41,485 m, Right: 328,075 m Coordinate System: NAD 1983 State Plane Massachussets Projection: Lambert Conformal Conic 34 records Just Maximum: 3% Maximum as well as something else: 15% Pre, AT, Minimum, Medium and Maximum Question 1-5: Similarly, what type of spatial dataset is LANDUSE2005_POLY – raster, vector, other? Question 1-6: What are the bounding coordinates (both decimal degrees and projected coordinates) of the SCHOOLS_PT dataset? Question 1-7: What is the coordinate system of the data frame? What is the projection? Question 1-8: How many records are in the Prisons dataset? Question 1-9: What percentage of prisons in Massachusetts are Maximum security? Question 1-10: What security category(ies) are combined (both males and females) assigned to?

3 Resolution: 8.2 * 10^-9 area of cell: 100 Total Area: 1,131,742,408 m^2. All Units are in Meters There is no Value Attribute Table because the file type is a raster which mean that it has continuous/variable data and is a combination of multiple attribute tables stored in a group of cells. This warning could mean that features within the prisons data set might be partially outside the Buffer Layer which means the “Clip” tool could not be used. Question 1-11: What is the resolution of this dataset? What is the area of a cell? Question 1-12: What is the Area of the “Very High” category? What are the units of the Area you just calculated? Question 1-13: What are the horizontal (x,y) units of the ELEVATIONS_PT layer – meters or feet? Although the legend in the TOC does not specify units, can you make a guess at the vertical units - meters or feet? Are the horizontal (x,y) and vertical (z) units the same? Question 1-14: Why do you think the Open Attribute Table… option is disabled (i.e. there is no Value Attribute Table) for this raster? Explain. Question 1-15: Why does Clip > PRISONS_PT with EJ2020_MIE_Buffer result in warnings? What are they and what does this mean for the analysis?

4 12 prisons in EJ communities 2 farmers markets in EJ communities 0.87 km^2 Question 1-16: How many prisons are in EJ communities with MIE criteria? What about farmers markets? Question 1-17: What is the total area (in km) of forested wetland in EJ communities with MIE in Massachusetts?

5 CEE 570 only - Question 1-18 : Using the ONLY tools you have learned in this lab; you need to assess the differences in land use between land within 200 m of different types of EJ communities. Determine the differences in land use between EJ communities containing just minority (M) versus communities with minority, English, and income (MIE). CEE 570 only - Question 1-19 : Next, suppose you were interested in correlating property value to locations next to forested wetlands. We will cover spatial statistics later in the semester, but for now, how would you approach this problem? What data would you need? Can you find a GIS layer online for this data?
