Class Project Brian McKean
RATIONALE • I was asked by the assistant to the Dean at the school of social work to map all of the field locations where research is being conducted.
BASE MAP USED • ArcGIS StreetMap provides nationwide address matching and street map display. ArcGIS StreetMap layers automatically manage, label, and draw features, such as local landmarks, streets, parks, water bodies, and other features. ArcGIS StreetMap can geocode addresses by interactively matching a single address or by batch matching from a file of addresses.With ArcGIS 9 StreetMap you can • Find addresses anywhere on a street network. • Quickly create intelligent maps. • Perform simple point-to-point or optimized routing across nationwide street networks.
ZOOMED IN STREET MAP • Metro St. Louis
“GEOCODING” • “the process of assigning a location, usually in the form of coordinate values, to an address by comparing the descriptive location elements in the address to those present in the reference material. An address includes any type of information that distinguishes a place. With geocoded addresses, you can spatially display the address locations and begin to recognize patterns within the information.”
WHAT I LEARNED • Geocoding is very time consuming if there are problems with your data • I should have given the client the format I needed – provided the column headings • I should have insisted that the client do the research on those addresses ArcGIS couldn’t geocode.
