Using Match Settings to Control Geocoding Precision
The Geocode dialog includes tabs that allow you to control the Match Settings, Fallback, and
Multiple Match settings for a geocoding pass. This allows you to control how restrictive MapMarker
is in identifying close match candidates.
Each of the settings affect the match rate, performance, and the positional accuracy of the geocoded
point. You must decide the settings that best fit you strategy and requirements. See
Choosing
Match Strategies .
Default Settings The default settings, which generally give you the best compromise among match
rate, accuracy, and performance, are:
• Require an exact match for house number only. See Match Settings Dialog .
• Do not fall back to ZIP Code centroid matching. Uncheck the setting in the Fallback dialog. See
Fallback Dialog .
• Do not match if there are multiple match candidates. Uncheck the setting in Multiple Match
dialog. See
Multiple Match Dialog .
Choosing Match Strategies
You can use several matching strategies, including:
• Maximizing the Match Rate on page 118
• Maximizing Geographic Accuracy on page 119
• Balancing Match Rate and False Positives on page 119
You can choose one method or use them in combination.
Maximizing the Match Rate
To generate the highest match rate possible, remove the match restrictions on house number, ZIP
Code, and street names in the Match Settings tab by unchecking those boxes. In addition, select
Accept First (Multiple Match tab) and Fallback to ZIP Centroid (Fallback tab). Less restrictive
match settings allow MapMarker to broaden the area in which it searches for a match. For example,
if a ZIP Code match is not specified, MapMarker can find candidates outside the ZIP Code but within
the city or financial area of your input address.
To maximize the potential for a match, tell MapMarker what to do if it does not find a match. These
settings include Fallback to ZIP Code matching and match to the first of multiple matches. See
Fallback Dialog and Multiple Match Dialog .
