googlemap2sqlite

================

Dump coordinates and descriptions from a [Google map](https://en.wikipedia.org/wiki/Google_maps) (KML 2.2) into a [sqlite](http://sqlite.org/) database. The coordinates are expressed in decimal degrees following the World Geodetic System of 1984 (WGS84). This scraper is mostly useful for data liberation and automated processing.

It creates two tables: places and coordinates. The [SQL](https://en.wikipedia.org/wiki/SQL) statements for their creation are

```

CREATE TABLE IF NOT EXISTS places (

  pid INTEGER PRIMARY KEY NOT NULL,

  name TEXT NOT NULL,

  description TEXT

)

```

```

CREATE TABLE IF NOT EXISTS coordinates (

  cid INTEGER PRIMARY KEY NOT NULL,

  pid INTEGER NOT NULL,

  longitude REAL NOT NULL,

  latitude REAL NOT NULL,

  altitude REAL

)

```

* **pid**: place ID as a key across tables

* **name**: (commoon) name of the place, often contains address information

* **description**: CDATA often containing links to corresponding posts on tumblr

* **cid**: coordinate (tuple) ID, one place may have multiple coordinates (e.g. a polygon)

* **longitude**: the longitude of the point described by *cid*

* **latitude**: the latitude of the point described by *cid*

* **altitude**: the altitude of the point described by *cid*, often set to 0.0
