Create maps using the Github Gist API as GeoJSON or TopoJSON, directly from PostGIS.
dev-branch
master
Create a command line utility similar to pgsql2shp, but the output of which should be a link to an anonymous private gist. The gist link should leverage Github’s rendering of GeoJSON/TopoJSON, e.g. render a map.
See issues for additional features to be implemented.
Listed below is the --help usage information.:
POST GeoJSON or TopoJSON features from PostGIS to a Github Gist.
Example usage: pgsql2gist --host localhost --user matt tilestache \
"SELECT name, ST_AsGeoJSON(geom) AS geometry FROM neighborhoods LIMIT 5;"
Current SELECT Statement Requirements:
- Geometry must be in EPSG:4326 WGS84 coordinate system
- Geometry must be wrapped in ST_AsGeoJSON(), ST_AsTopoJSON()
usage: pgsql2gist [-f FILE] [-d DESCRIPTION] [-h HOST] [-p PORT] [-P PASSWORD]
[-u USER] [-g GEOM_COL] [-t TOPOLOGY_LAYER] [-v] [-?]
database SELECT
positional arguments:
database PostGIS database name.
SELECT SELECT Statement. NOTE: Geometry must be WGS84;
wrapped in ST_AsGeoJSON() or AsTopoJSON().
optional arguments:
-f FILE, --file FILE Filename. NOTE: Must end in 'geojson' or 'topojson'
extension. (default: upload.geojson)
-d DESCRIPTION, --description DESCRIPTION
Description of upload (default: File uploaded using
pgsql2gist.)
-h HOST, --host HOST PostGIS database hostname. (default: None)
-p PORT, --port PORT PostGIS database port. (default: 5432)
-P PASSWORD, --password PASSWORD
PostGIS user password. (default: None)
-u USER, --user USER PostGIS database user. (default: postgres)
-g GEOM_COL, --geom-col GEOM_COL
Geometry column name as defined in SELECT statement.
(default: geometry)
-t TOPOLOGY_LAYER, --topology-layer TOPOLOGY_LAYER
For TopoJSON Queries; Name of Topology Layer (default:
None)
-v, --verbose Verbose output. (default: False)

The spiffy idea behind a db context manager comes from Migurski's awesome TileStache map server. http://tilestache.org
