Birth of the 3D Elevation Program: How a Map Factory became a Big Data Producer

For over 130 years, the US Geological Survey (USGS) has been the nation’s premier governmental map making organization. Gone are the days of producing maps from topographic surveys, artistic sketches and printing on copper plates. Today’s topographic maps are derived from high resolution digital data designed to be consumed on a variety platforms. The need for high resolution elevation data is vast and increasing demand has led to the creation of the 3D Elevation Program.

Adding weather data to your geospatial applications using Open Source tools (sponsored by IBM)

Weather is something that affects everybody's daily life and is closely tied to the geographic location. In the session, you will learn how to integrate weather data from IBM Weather Company in your geospatial application using open source technologies such as Python, Spark and Mapbox GL JS that leverages IBM Watson data and AI platform. Weather Company provides most accurate weather forecast and is used by over 100 million users.

Data Science Mapping in Jupyter Notebooks with Pixiedust: the sequel (sponsored by IBM)

The Jupyter Notebook is a web application that allows you to create and share documents that contain live code, equations, visualizations and explanatory text. The Jupyter stack is built from the ground up to be extensible and hackable. The Developer Advocacy team at IBM Analytics has developed an open source library of useful time-saving and anxiety reducing tools we call “PixieDust”. It was designed to ease the pain of charting, saving data to the cloud and exposing Python data structures to Scala code.

Building an Image Processing Pipeline at Scale using Open Source (sponsored by Boundless)

Farmers Edge provides innovative agricultural practices that help growers boost crop production and improve sustainability.  After recently acquiring an exclusive industry wide redistribution agreement for Planet data, Farmers turned to Boundless and Open Source GIS to build an image processing pipeline capable of handling the throughput of such a large collection.  Come hear how Spark, GeoTrellis, GeoServer, Elastic and Azure were used to build a first class processing pipeline

Breaking the 4th Dimension: temporal data in PostgreSQL and PostGIS

It is “well known” that 80% of all data has a spatial component. What is less well known is that 100% of data contains a temporal component. For some data it may simply be the date that the data was released. For other, there may be a separate date/time for each separate row or feature. And yet still for others, such as vehicle tracks, there is time information that changes along a feature itself.

This talk will give an overview of some of the issues involved in dealing with temporal data with PostGIS and PostgreSQL.

Tackling our planet's toughest problems with satellite imagery, open source tools, and geospatial analytics

The increasing abundance of satellite imagery has unlocked new insights and understanding of our planet. Novel approaches to imagery analytics with open source tools, applied to a growing set of publicly-available data (under CC BY-SA 4.0) are helping us unlock new solutions to tackle some of our planet's toughest challenges, from disaster response to climate protection to crop yield forecasts. This talk will feature real-world examples of open source tools and computer vision approaches used to address a variety of critical issues humanity faces.

Regional carbon budgets for high value forest landscapes using FOSS Geospatial tools

For 27 years the Institute for Sustainable Forestry has worked to promote the long term economic, ecological and social well being of forest based communities through sustainable forest management.  In recent years, several negative environmental trends have emerged in California's Coastal temperate rainforest watersheds including declining Summer instream flows, extreme anthropogenic sediment yields, and susceptibility to catastrophic wildfires.
