Tableau Prep is quietly sneaking up to Alteryx, and native spatial joins are a genuinely huge addition.
Tableau Prep now supports spatial calculations and joins natively. Functions like make point, make line, buffer, distance, area, and intersects are all here. Plus, points, lines, and polygons can now sit in the same column. This was already possible in Desktop, but bringing it to Prep is huge for anyone doing location-based data work. Feature parity is creeping up, and the Prep interface remains one of the best out there.
