Big Spatial Data

Are FOSS4G Tools we love

Too weak for Big Data?

How To Go Big?


Scale Out!

Easy in the cloud (AWS etc.)

Many specialized tools

Growing user base (even some GIS people)


Great lack of spatial functionality

Great lack of knowledge

Great lack of communities

Writing queries can be a PITR

Why not stick to our guns?

Do we actually have Big Data?

Not needed for simple features...

Big Spatial Data

These are not simple features

What do these examples have in Common?

But, it does not feel like the right match. and yes, it's slow...

We CAn use PostGIS.


Extend FOSS4G tools


Data Processing Pipelines

Data Streaming


Postgres forks, GDAL, PDAL


SciDB, MonetDB, MapD


GeoTrellis, PySpark, R
