It needs:
*portcomaster-- built in new BuildBaseTables*tiger2-- built in AgglomerationVcdb4.sql from TigerModified, which combines 7 encapsulated places with their encapsulators (see section below).*portcogeo-- built in load tables and modified there to create lat4 and long4, which have 4dp (11.1m) of precision, which wikipedia lists as a land parcel and roughly corresponds to an office front.*roundsummary ->placeyearvc-- Roundsummary doesn't exist anymore. We'll build placeyearvc from a different base*rankingfull-- Requires deciding how to deal with places (see below).
*Cpi - done in Load.sql
When doing the synthetics for Houston, we need a central location and hull size. The 2007 hull centroid was at (long,lat=-95.47029505572422,29.745008286648368). The WeWork in The Galleria on Westheimer is at (-95.4765668, 29.7256031). We'll use a scaling hull size of 1 hectare per startup. For a 25 hectare district, we would do sqrt(25)/2 as the plus-minus in hm, where 1 hm is 0.0000898 degrees (at the equator for latitude). Or more broadly, the degree +/- for an x hectare district is:
+/- = ((sqrt(x)/2)*0.0000898)
