Want to get involved? We're always looking for ideas and content for Weekly Challenges.
SUBMIT YOUR IDEAWe are 1 week out from challenge 150! Yes, that's right, a new badge is available starting next week for those we are up to date on all challenges!
In this week's challenge, we are going to be doing some calculations for market overlap!
Objective:
A retailer wants to analyze overlap for his current location's trade area against future locations.
1: For each proposed location, determine the % overlap of the existing location (e.g. if a proposed location overlaps 60% of the existing store's TA, the answer is 60%).
2: determine what % of current customers live inside each of the proposed trade areas
Summary of Data:
Proposed Locations polygon layer
Current location polygon layer
Current Customers
Hints: Customer Lat/Longs are integers
When joining to check your answer, don't join on a Double or Float.
Cheers!
Went for a Spatial Formula approach...
ST_Area(ST_Intersection([TradeArea],[SpatialObject_TradeArea]),"SqMi") / ST_Area([SpatialObject_TradeArea],"SqMi")*100
IIF(ST_Contains([TradeArea],ST_CreatePoint([LONGITUDE]/1000000,[LATITUDE]/1000000)),1,0)Then just average :)
Spatial challenges are always great :)
