Enter a valid UK Postcode or coordinate pair (Lat, Lng) to place a location precisely, or leave blank to drop it in the centre of the screen.
Upload a CSV file to generate multiple companies and locations simultaneously. The CSV headers must exact match the following format:
If disabled, market shares are calculated simply as total allied volume divided by total volume within the catchment area, regardless of distance.
Set the volume thresholds that define the minimum (16px) and maximum (80px) size of location nodes on the map.
In competition economics, authorities evaluate retail mergers by analyzing specific geographic catchments.
We define a local market by a Maximum Distance (Dmax in Kilometers), representing how far a consumer is willing to travel.
Competitors located right next door exert massive pressure, while competitors on the edge of the catchment exert very little. We calculate real-world kilometer distance (d) using the Haversine formula, and weight each store's volume:
To find a specific location's local market share, we take its volume, add the weighted volume of all allied stores in range, and divide it by the total weighted volume of ALL stores in range.
Instead of calculating volume shares, this mode simply counts the number of distinct corporate entities (fascias) operating within the catchment area, including the target location. Authorities often use "4-to-3" or "3-to-2" fascia reduction screens as an initial indicator of local market concentration.
