A location assessment with WIGeoLocation is as easy as can be

The WIGeoGIS team integrates the additional gravity module, configures the settings in WIGeoLocation once based on your individual requirements, incorporates the correct data into the program and calibrates the Huff gravity model for you. After that, you can log in at any time via your browser and assess planned locations, the effects of location closures or relocations and the effects of new competitor locations on your sales with just a few clicks of the mouse.

This is how it usually works:

  1. You enter the location address or mark the planned location on the map.
  2. You select the catchment area from which you expect customers and set a travel time for them to reach your location, for example up to 10 minutes.
  3. Now enter the attractiveness of the location and click on "Request location report".
  4. The program performs a Huff gravity analysis in the background and in a matter of seconds you will receive the report on the location assessment.
  5. Now you know how much sales potential your new location has and how it will affect the sales of existing locations.

Site evaluation with the help of Gravity Analysis

2 examples of location evaluation using gravity analysis. On the left, you determine your sales potential based on the existing competitive situation. On the right, you can see the changes in your sales potential if a new competitor (Competitor 5) were to locate to the east of your site. The GIS software WIGeoLocation evaluates at the push of a button.

My Data, your Data

In a gravity analysis, the quality of the location assessment depends primarily on the quality of the data that is entered into the software. It is therefore important to enter high-quality data on the defined attractiveness parameters of the locations, including both your own and that of your competitors.

WIGeoGIS provides the location data on the number of residents in the respective catchment area and their purchasing power as well as the calculations of the distances between locations and customers. On the user side, local know-how is beneficial in order to be able to assess the attractiveness of existing locations as well as the possible attractiveness of a new location. This makes the location assessment and sales forecast even more reliable.

This is How the Gravity Analysis Works for Your Location Assessment

QGIS – The Alternative for Experts

For companies with their own GIS experts, WIGeoGIS offers QGIS-Software with a suitable gravity plug-in for gravity analysis according to Huff. QGIS is installed on your company computer and enables your GIS experts to use the Huff model quickly, easily and efficiently without doing the calculations themselves. Your in-house GIS experts only enter and calibrate the parameters for the Huff gravity analysis. If a recalibration is necessary, you can also do this yourself.

  • How long does it take before I can prepare my first gravity analysis reports?

    This can be done very quickly with WIGeoLocation. The WIGeoGIS team can often incorporate the data and perform the basic calibration within a week. As soon as this is done, users can create automated reports at any time with just a few clicks in the browser. If you use QGIS, the software for experts, you first need several days of basic training in order to be able to perform the calibration yourself. Theoretical previous knowledge of Huff's gravity model is helpful.

  • What if the sales forecast does not seem realistic?

    It may be that the basic settings were too optimistic or too pessimistic. In order to make the analysis more accurate in such a case, we at WIGeoGIS can recalibrate the models based on sales data and thus react dynamically to changes in the market. Basically, the following applies in any case: The better your regional knowledge of the planned location, the more accurate the sales forecast in the WIGeoWeb or QGIS software.

  • For whom is the add-on module for gravity analysis worthwhile?

    Companies that have several branches or locations and where the network of locations is constantly changing can benefit greatly from the gravity analysis software from WIGeoGIS. Even companies that sell their products through partners in brick and motor retail (such as milk, cosmetics or shoe manufacturers) can significantly improve and simplify their location planning using the gravity analysis in WIGeoWeb or QGIS. Companies with only a handful of branches and no expansion plans will likely have no need for gravity analysis software.

  • For whom is WIGeoLocation suitable and for whom is QGIS better?

    The add-on module for gravity analysis in the web-based GIS software WIGeoLocation is suitable for those companies that do not have any specific expertise in geographic information systems (GIS) and do not want to invest in acquiring it. For GIS experts, however, QGIS, the desktop version of the software, is recommended.
