iMaptools offers excellent geocoding solutions and since we have been writing writing geocoders for 14+ years we understand the technology choices, the OpenSource choices and the issues involved with building and using geocoders. Our new generation of SQL geocoders are now built as stored procedures in PostgreSQL database. This OpenSource database is easy to deploy on Windows and Linux environments and much of the code is written in SQL making use of the high performance indexed searching the a rational database provides and making it easy understand and modify. For reference street data in the 50-80 million row tables covering all of North America we can geocode large tables of addresses in 50-100 ms per record on average.
We have support for loading data from US Census Tiger data and Navteq data. In fact for our Tiger based version we provide the data so clients can be up and running in hours. One of the key strengths of the current design is that is data set agnostic, which means we can take most any data that has address information and search for the records associated with those address. We are happy to develop loaders for other data and/or modify the geocoding behavior to meet specific client needs if the current code does not already meet those needs.
