Magical PostGIS in three brief movements
Everyone knows you can query a bounding box or even spatially join tables in PostGIS, but what about more advanced magic? This short symphony of PostGIS examples will look at using advanced features of PostGIS and PostgreSQL to accomplish surprising results:
* Using full text search to build a spatially interactive web form.
* Using raster functionality to look into the future.
* Using standard PostgreSQL features to track and visualize versioning in data.
PostGIS is a powerful tool on it's own, but combined with the features of PostgreSQL, it is almost magical.
