Web Based GIS application (GISCube)

There are many Earth science projects and data systems being developed at the Jet Propulsion Laboratory, California Institute of Technology (JPL) that require the use of Geographic Information Systems (GIS). Three in particular are: (1) the JPL Airborne Snow Observatory (ASO) that measures the amount of water being generated from snow melt in mountains; (2) the Regional Climate Model Evaluation System (RCMES) that compares climate model outputs with remote sensing datasets in the context of model evaluation and the Intergovernmental Panel on Climate Change and for the U.S.

Spatial Containers for the Cloud

Linux containers (via Docker), are quickly becoming a fundamental building block in the design and delivery of cloud services.

This talk provides an overview of my favorite spatially-focused Docker images, and demonstrates how these images can be used to compose advanced multi-container services for the cloud.

Geodata Processing with Node.js

This session will introduce a few key open source tools for geodata processing in Node.js. We will cover both native and pure javascript modules that work with formats ranging from GeoJSON to Vector Tiles. With these tools you can easily explore and utilize geodata in scalable ways. We will focus on tools like node-mapnik, node-gdal, and other Node.js C++ addons that expose the power of long-standing C++ libraries for tasks like rendering, spatial datatype conversion, filtering, and projection transformation.

AequilibraE - A free QGIS add-on for transportation modeling

Commercial software for transportation modeling cost is in the range of US$10,000 to US$30,000+, and currently no successful open source alternative exist.

AequilibraE is the first QGIS add-on for transportation modeling/planning and it aims to be a fully fledged open source software for transportation modeling. It builds upon the success of QGIS and the need of transportation modelers to have a modeling tool with an excellent GIS interface.

GeoServer, an introduction for beginners

This tutorial will provide an introduction to the GeoServer project and its abilities to publish data with a mix of well known OGC protocols and other pupolar protocol and data formats, including:

  • Setting up vector and raster data from the GeoServer administration control

  • Publishing data via WMS, WFS and WCS

  • Styling layers using desktop tools, with a carousel of GeoServer mapping abilities

  • Tile caching with WMTS

Status of GeoServer WPS

This presentation will provide the attendee with an introduction to the GeoServer WPS functionalities, and will highlight the recent improvements in the area.

We will start by a brief introduction to the WPS protocol, show how GeoServer available functionality maps onto it, to then move to the GeoServer integration abilities to directly access local data, mix togheter WMS and WPS with rendering transformations, as well as integration with the data import functionalities.

Caching is Your Friend - Creating Tons of Maps on the Fly and Auto-Updating Some

Julie Goldberg is the co-founder and chief engineer behind Empower Engine, a 2-person start-up that maps electoral campaign data for Democrats and their allies. She’ll talk a bit about the domain and a lot about some technical challenges she faced, mostly solved by caching. The system is built using Django, Leaflet, Tilestache and Postgres.

Think Before You Code (... & Other UX Considerations)

In 2014, NOAA Coastal Services Center, ASFPM, USACE, ERG, and the City of Toledo partnered together to conduct an assessment of the implication of future climate models on chronic urban flooding in Toledo, and the effectiveness of green infrastructure in mitigating the financial losses imposed by flood events. The Flood Hazard Visualizer utilizes an array of open source libraries to transform the results of this assessment into an interactive tool that supports the needs of both novice and expert users.
