Description
Lab 2: Address Geocoding By Paloma D’Silva Dr. Sohn EATS 3300 Introduction In this lab, students were asked to geocode addresses that did not have address information such as X and Y coordinates, and to convert the address description into location data that does contain X and Y coordinates. The address data provided was of fire stations in the GTA area, and this information was given in an Excel file. In order to geocode the addresses; the Geocoder 10.1 North America Geocode Service was used. The output file is as follows: Figure 1-Geocoded Addresses After this, the geocoding toolbar was activated, and according to the geocoding result, 19 addresses matched, and this was 100% of the addresses listed. There were no unmatched addresses at all. Then, 4700 Keele Street was located on the map, using select elements. Task 3 Task 2 was to find the fire station closest to York University, and for Task 3, an image file with the selected attributes of fire stations 5 km away from the university was created. An Excel file with the same attribute fields as the fire station Excel file was created, and named York U. Then, York University was geocoded on the map. The output is shown in Figure 2 below. There are three fire stations within a 5km radius of York University. The closest one is Fire Station ID 141, 3.0 km away from the University. The other two fire stations within a 5km radius are Fire Station 142, and Fire Station 143. The fire station furthest from York University is Fire Station ID 2, 14.7 km away from the university. A map of the fire station area has been shown in Figure 3. Figure 2—Fire Stations Figure 3—Fire Station Map Task 4 Task 4 was to find data for five high schools in the GTA and geocode the addresses. The data for the high schools are shown in Table 1 below. Table 1-Toronto Secondary Schools ID School Name Address City Pr
