Geocoding Techniques and Technologies for Location-Based Services
Published in Hassan A. Karimi, Advanced Location-Based Technologies and Services, 2016
Geocoding is the process of converting textual locational information into one or more geographic representations (Boscoe 2008). Most commonly this process is used to convert postal mailing addresses into geographic coordinates for mapping, visualization, or analysis purposes. Geocoding plays several critical roles within the context of location-based services (LBS). Among many others, these include (a) the translation of an input query location into a geographic context that can be used as input to an LBS query such as “find golf stores nearby 123 Main Street”; and (b) the generation of the location databases that serve as the foundational layers upon which an LBS can search for answers to queries such as “find all grocery stores nearby my current location.”

The process of converting a human-readable address into geographic coordinates is called geocoding. While there are numerous APIs available online that will do this for you, this functionality is provided in ggmap by the geocode() function.
Data collection, processing, and database management

Geocoding: Geocoding is the computational process of transforming location information such as a postal address to a location in terms of geographic coordinates. This is quite useful for integrating address-based data with other types of spatial data.

The process of converting locations into their geographical coordinates is termed geocoding. The RTA locations along Jalan Tutong were recorded in a spreadsheet in eastings and northings in the World Geodetic System 1984 (WGS 1984). RTA attributes were also recorded in the spreadsheet, including direction of traffic flow (i.e., BSB-bound and Tutong-bound), types of intersection where accident took place (e.g., T-junction, +-junction, Y-junction, etc.), crash type (e.g., self-accident, two-vehicle, three-vehicle, vehicle-motorcycle/-bus, etc.), crash movement type (e.g., head-on, lane change, loss of control, etc.), weather and road conditions (e.g., lighting, roughness, etc.), time and date of accident, number of people involved, severity, and contributory factors (e.g., poor turn, failed to look properly, slippery road, sight distance issues, etc.). These enabled investigators to understand the accident circumstances – driver’s behaviours, sight distance, road geometric design, infrastructure or vehicle defects and the descriptive accident patterns (Raut, Dhumal, Nagne, & Kale, 2015). RTA that did not have location information were not geocoded.

The last step is to identify noun phrases that pertain to public locations, and this was achieved by processing the noun phrases using a geocoder. Geocoding is the process of converting location names or addresses to coordinates. The Python client geopy was used to interface with Bing Maps to geocode noun phrases from tweets to identify the ones that correspond to places and plot their locations (Esmukov & Tigas, 2018). As location names are not unique across the world, the geocoder was set to ignore results that fall outside the boundaries of the study.
