Create a folder called \ufffd\ufffd\ufffdMidterm\ufffd\ufffd\ufffd on your desktop and save there the geodatabase under ASSIGNMENTS\ufffd\ufffd\ufffdMIDTERM \ufffd\ufffd\ufffd MidTerm Computer Part \ufffd\ufffd\ufffd data.mdb. The file is not zipped<\/p>\n
so you should be able to add and read its contents directly In ArcMap.<\/p>\n
You will find four layers in the geodatabase:<\/p>\n
\ufffd\ufffd\ufffd\t\ufffd\ufffd\ufffdHouses\ufffd\ufffd\ufffd: This is point feature class representing house locations. It has one field (CID) that contains a unique identifier for each house.
\n\ufffd\ufffd\ufffd\t\ufffd\ufffd\ufffdHouse_Characteristics\ufffd\ufffd\ufffd: This is a table that contains four attributes: a unique identifier for each house (CID), the number of occupants per house<\/p>\n
(NumPeople), the size of the floorplan in square feet (SqFootage), and the property value in thousands of dollars (PropValue).
\n\ufffd\ufffd\ufffd\t\ufffd\ufffd\ufffdRiver\ufffd\ufffd\ufffd: This is a line feature class that represents a river that crosses the study area.
\n\ufffd\ufffd\ufffd\t\ufffd\ufffd\ufffdRoads\ufffd\ufffd\ufffd: This is a line feature class that represents the center lines of main streets and avenues. It has three attributes: the name of the street (ST_NAME),<\/p>\n
the type (ST_TYPE), and the length of each street or avenue segment (Shape_length).
\n\ufffd\ufffd\ufffd\t\ufffd\ufffd\ufffdFloodplain\ufffd\ufffd\ufffd: This is a polygon feature class that represents the extent of the 100-year floodplain (the maximum flooding area in the past 100 years) and 200-<\/p>\n
year floodplain (the maximum flooding area in the past 200 years). It has three attributes: the maximum flooding area in the past 100 and 200 years (Floodplain_Year =<\/p>\n
100 or 200), the length of the perimeter in feet (shape_length), and the area in square feet (Shape_Area)<\/p>\n
Instructions<\/p>\n
\ufffd\ufffd\ufffd\tPlease type your answers in this word document and, when finished, upload it directly onto CANVAS (Midterm\ufffd\ufffd\ufffd Computer Based Part).<\/p>\n
\ufffd\ufffd\ufffd\tFor each question, write down the type of query and the steps you took to answer it and the numeric results. Each question is worth 5 points.<\/p>\n
\ufffd\ufffd\ufffd\tAt the end of each question you will find the layers that are needed to solve the problem. This part is due Tue, Feb 7 at 3:30 pm (when class starts). Late<\/p>\n
exams will not be accepted or graded.<\/p>\n
1)\tIf a flood affects the surface area of the 100-year floodplain: How many people will be directly affected? How many houses will be damaged? If the cost of the<\/p>\n
damages is 1% of the total property value of all affected houses, what will the costs of the losses be (in thousands of dollars)? Use \ufffd\ufffd\ufffdHouses\ufffd\ufffd\ufffd and \ufffd\ufffd\ufffdFloodplain\ufffd\ufffd\ufffd. Link<\/p>\n
the table \ufffd\ufffd\ufffdHouse_Characteristics\ufffd\ufffd\ufffd to \ufffd\ufffd\ufffdHOUSES\ufffd\ufffd\ufffd based on CID.
\nType of query:
\nSteps:<\/p>\n
2)\tHow many houses have more than or equal to 7 people and have a square footage of more than or equal to 3000 sq. feet but do not have a property value of more<\/p>\n
than $350 K? Use \ufffd\ufffd\ufffdHouses\ufffd\ufffd\ufffd
\nType of query:
\nSteps:<\/p>\n
3)\tIf the flood severely damages the road network in the 100-year floodplain area, what percentage (roughly) of the total road network will require some<\/p>\n
maintenance because of these damages? Use: \ufffd\ufffd\ufffdRoads\ufffd\ufffd\ufffd and \ufffd\ufffd\ufffdFloodplain\ufffd\ufffd\ufffd
\nType of query:
\nSteps:<\/p>\n
4)\tIf the flood affects the houses within 2 miles of the river channel, how many houses will be affected?
\nFrom this subset, how many: fall within the 200-year floodplain only (not in the 100-year floodplain), have a square footage of more than 3546 sq. feet, have less than<\/p>\n
5 occupants, and cost $500 k or less? These four criteria occur simultaneously.
\nUse \ufffd\ufffd\ufffdRiver\ufffd\ufffd\ufffd, \ufffd\ufffd\ufffdHouses\ufffd\ufffd\ufffd, and \ufffd\ufffd\ufffdFloodplain\ufffd\ufffd\ufffd.
