ArcGIS geocoding performance

Geocoding performance has always been a top priority when working with large volumes of addresses, and it’s a primary consideration when designing and implementing a geocoding workflow. There are several factors that contribute to geocoding performance, I won’t cover all of these in this article but, let’s look at some simple, high value changes we can make to our locators and workflow to improve performance.

Increasing the run time memory limit:

ArcGIS Locators can be configured to use more system memory. Using system memory (RAM) to work with locators is much faster than reading a locator from disk. ArcGIS supports use of 2GB memory on a 32 bit system and 3GB of memory on a 64 bit system. By default ArcGIS locators are configured to use 512MB of system memory. The default values were chosen to ensure the greatest possible system coverage, without exceeding system limits and possibly destabilizing a system. By increasing the memory allocation for locator use above 512MB we see good performance gains.

ArcGIS locators support a “Run Time Memory Limit” parameter. For large geocoding jobs working against a large locator such as US streets, or US Composite, we’ll want to set this limit near the capabilities of our system. With ArcGIS 10, geocoding performance continues improving as the cache grows beyond 2GB.

Follow the steps below to create or edit an existing Run Time Memory Limit parameter:

  1. Open the *.loc file in a text editor (note this is the .loc file and not the .loc.xml file).
  2. Look for the line that starts with RuntimeMemoryLimit =
  3. If the value does not exist, create one and change the value to represent the number of bytes of system memory you want to allocate for the locator:
  4. Save the locator.
  5. Use the locator and compare performance and system memory use.

You can play with this value to find something that is appropriate for your system. In most cases you will see optimum performance near 2GB of memory. If you’ve allocated too much memory, the system may become unstable or ArcGIS may crash. Reduce the memory allocation to rectify.

Presort reference data for optimal performance:

It’s always much faster to find something when it is organized than when it is chaotic. Geocoding is no different. Sorted addresses can be geocoded faster than unsorted data. Sorted addresses tax the system less, hard disks don’t have to work so hard and the geocoding engine makes less frequent memory allocations.

Web Site Shows Neighbor Campaign Donations

Just type your address and ZIP code into the "Neighbor Search" tool at fundrace.org, and you'll get a list of what your neighbors gave to any of the presidential candidates last year - and how much.
Your nearest neighbors are listed first.
The tool uses technology called geocoding, which matches street addresses with longitude and latitude data. The match works about 70 percent of the time; in cases of failure, results are given based on ZIP code. Visitors can also search by name.
Candidates, by law, are required to disclose contributions of $200 or more, and the Federal Election Commission makes databases available for download
