As more than 70% of all business records include a location component, it is not surprising that location accuracy has become such an important part of data quality. Today, organizations are using location data to administer market analysis, risk assessment, effective targeting, network investments, site selection and portfolio management.
Before you can analyze, extrapolate or profit from location data, you first need to associate each record with an accurate latitude and longitude coordinate. That’s why so many organizations employ geocoding. Geocodes translate common reference points, such as customer addresses, into latitude and longitude coordinates that makes it easier to analyze data. If your geocode is wrong, however, your analytics are wrong, your insights are wrong—and your decisions are wrong—so it pays to be accurate. Today’s best practices include:
1. Validate source addresses
Geocoding tools should offer the ability to cleanse data, standardize addresses and validate that source addresses are correct before applying geocodes.
2. Validate geocode results
Accuracy has another element, positional accuracy, which measures how close the geocode is to the reference point. Geocoding an address to the center of a city, for example, will be less positionally accurate than one centered on a precise parcel or rooftop. Today’s leading solutions provide a ‘geo-confidence index’ that estimates the probability that the latitude and longitude assigned correspond to the place intended.
3. Utilize precise, up-to-date reference data
How often you update your reference data is important, as reference points such as roads, addresses and developments are always being added and modified. Many companies do quite well with quarterly data refreshes.
4. Geocode to multiple levels of accuracy
There will be times when it is not possible to deliver a geocode centered on a specific address or parcel. The tools you use should recognize this and apply consistent rules, automatically cascading to the next most-specific point of reference, from address point, to street level, to postal code, city, state, etc.
5. Combine geocoding and spatial analysis
Ultimately, the goal of any solution is to provide answers, not latitudes and longitudes. Look for tools that combine geocoding with the ability to perform analysis, calculations and predictive analytics, such as point-in-polygon analysis, closest site analysis and the ability to calculate drive time and distance.
6. Integrate into existing workflows
When you can integrate geocode analytics into existing operations and business processes, you can which streamlines workflows, eliminate manual processes and improve decision making.
7. One-stop service
Solutions need to be simple to use and flexible enough to meet different business requirements. A single technology platform that matches up with your overall corporate objectives can help ensure that a consistent standard will be applied in every market. Likewise, maintaining one platform reduces cost of ownership and can speed up system integration. A single interface also simplifies training and education, and makes it easier for your company to gain the skills and capabilities in Location Intelligence needed to achieve a competitive advantage.
