Improving Geocoding Practices: Evaluation of Geocoding Tools

Journal of Medical Systems, 2004
This study examined the sources of error involved in geocoding, by systematically evaluating the strengths and weaknesses of three widely used tools for geocoding. We tested them against a random sample of addresses from a state administrative address master file and found considerable variation in identification of census block geocodes of addresses ...

Improving geocoding quality via learning to integrate multiple geocoders

32nd International Conference on Scientific and Statistical Database Management, 2020
In this paper, we introduce an approach for improving the quality of the geocoding process. Geocoding refers to the procedure of mapping an address of textual form to a pair of accurate spatial coordinates. While there is a variety of available geocoders, both open source and commercial, that curate this mapping in either a semi-automated or fully ...

What3Words Geocoding Extensions

Journal of Geovisualization and Spatial Analysis, 2018
With the advent of location-based services, the demand for location data has dramatically increased. Geocoded locations have become necessary in many GIS analysis, cartography, and decision-making workflows. A reliable geocoding system that can effectively return any location on earth with sufficient accuracy is desired.

Geocoding sensor networks

2007 Fourth International Conference on Networked Sensing Systems, 2007
This demonstration shows how to geocode information originated from sensor networks. Geocoding is a technique to graphically represent information in a "map to be seen" (Bertin 1967). The demonstration presents: 1.) a toolset to overlay sensor network information including sensor and context data, with geographic maps; 2.) a sensor network ...

Multimedia multimodal geocoding

Proceedings of the 20th International Conference on Advances in Geographic Information Systems, 2012
This work is developed in the context of the placing task of the MediaEval 2011 initiative. The objective is to geocode (or geotag) a set of videos, i.e., automatically assign geographical coordinates to them. This paper presents an architecture for multimodal geocoding that exploits both visual and textual descriptions associated with videos.

Geocoder Accuracy Ranking

2014
Finding an address on a map is sometimes tricky: the chosen map application may be unfamiliar with the enclosed region. There are several geocoders on the market, they have different databases and algorithms to compute the query. Consequently, the geocoding results differ in their quality. Fortunately the geocoders provide a rich set of metadata.

Advanced Geocoding Topics

2007
In this chapter, you’ll learn how to create your own geocoding service. However, there are geocoding services already available for all sorts of data, and we covered many of them in Chapter 4. Therefore, this chapter is intended for professionals and serious hobbyists who are building web applications where using third-party geocoding tools is not ...
