The SMP package consists of a file geodatabase containing street data for North America along with several associated datasets such as county and municipal boundaries. SMP is based on commercial street reference data from HERE and INCREMENT P. Data is available for North America, Europe, Latin America, the Middle East and Africa, and Asia Pacific.the University Library has purchased an annual subscription to the North American dataset. Features include multi-scale, high-quality cartographic maps for display accurate geocoding (batch, reverse, and simple search) and optimized routing, driving directions, and network analysis. SMP is designed specifically for use with ArcGIS Desktop, ArcGIS Pro, and ArcGIS Enterprise.

If you would like to add additional functionality, some Python scripting knowledge will be advantageous.Streetmap Premium Authoritative data for mapping, routing, & geocodingĪrcGIS StreetMap Premium (SMP) provides enriched street data for use in ArcGIS software. Simply navigate to the toolbox in an ArcCatalog window, right click on the script and select “Edit…” to be able to incorporate the additional records as and when required.

If you’ve never used Python, don’t despair, the tool already does most of the heavy lifting for you and there is still much to be gained by adding text replacements and additional street types to the portions of the code indicated below. Applying the 80/20 principal we have attempted to use the minimal amount of code in order to clean and normalise the majority of addresses, however each dataset is going to have its own nuances so it will be up to you modify the script in order to optimise it for each of your use cases. You can use it in the same way you would use any other tool in ArcMap.

Preparing addresses for batch geocoding can be quite tedious, so we have created a toolbox to get you started with automating the process!Ĭlicking the image above will download an archive containing a toolbox with a simple Python script that uses a lookup table of freely available data from Statistics South Africa and the South African Post Office to attempt to normalise and clean address datasets prior to geocoding particularly for ArcGIS Online. If you are going to include postal codes in your addresses to geocode, please ensure they all have four digits, otherwise ArcGIS Online will not recognise the postal code for what it is. What makes things even more confusing is the fact that a particular street may have a ‘box’ code and ‘street’ code which differ and both may not be accurately represented in the reference data being matched against. Many people do not even know their postal code and it does more harm than good by including an incorrect postal code in an address for geocoding in ArcGIS Online as the address will be scored down. You are more likely to get an accurate geocode using a city alone instead of using a suburb which does not match the suburb in the reference data you’re matching against. The inclusion of extensions creates an additional host of problems and often suburb names change, or an individual may say their street falls in a neighbouring suburb for various reasons. Suburbs in South Africa remain loosely defined and differ from dataset to dataset. If an address does not match the patterns in the locator, your geocodes suffer.īest practice is to ensure your addresses look as follows: The ArcGIS Online geocoder uses a form of programmatic pattern matching. This is for a number of reasons, the most obvious being that often the incorrect information is captured in the wrong field.

Geocoding single-line addresses is both faster and often more accurate than feeding the address records to the geocoder field by field. Here are a few helpful tips which will help ensure accurate geocodes when using the World geocoder in ArcGIS Online. There are a number of variables at play which can affect the final outcome of a geocoding exercise (the most pivotal being the quality and accuracy of the reference data you are matching against) and it is never as simple as receiving an address dataset and geocoding it, often times clients want quantifiable measures of accuracy for the geocoded dataset and the GIS personnel working on the project are often expected to clean and normalise addresses in order to improve match rates.

The purpose of this article is to provide some insight into how to better manage an address dataset which would potentially be batch geocoded and how to optimise the capturing of these address datasets for geocoding in ArcGIS Online.

Often information is captured in free text fields which results in data irregularities and inconsistencies. Most commonly address information that is stored in a database is not something that is regularly maintained. Placing an address on a map either to find or place or to provide business context is becoming vitally important in our society.
