Falsehoods programmers believe about addresses

This is an anchor-linked version of the excellent, amazing original opus magnum by Michael Tandy.

An address will start with, or at least include, a building number.

Counterexample: Royal Opera House, Covent Garden, London, WC2E 9DD, United Kingdom.

When there is a building number, it will be all-numeric.

Counterexample: 1A Egmont Road, Middlesbrough, TS4 2HT

Indexing of Vector Tiles (Clipping Justification)

This pull-request provides the ability to display vector tile trees containing leaves at different levels of detail (LOD) based on data density. This requires clipping tiles when zoomed in beyond a physically present leaf and using an index to determine tile presence.

Purpose

The goal is to efficiently cook tiles and still maintain a high level of data precision in vector tiles. We can achieve this by limiting the cooking of tiles to a satisfactory LOD in less geometrically dense areas. On the consumer side, clipping can be used to clip larger tiles to fit a more precise LOD as needed. This methodology also provides over-zooming of tiles beyond the LOD limit of the current Vector Tile specification.

PostgreSQL & PostGIS Cheatsheet

This is a collection of information on PostgreSQL and PostGIS for what I tend to use most often.

TOC

• Installing Postgres & PostGIS
• Using Postgres on the command line: PSQL
• Importing Data into Postgres
• Exporting Data from Postgres
• Joining Tables
