From UAV to Orthomosaic: Building a Toolchain

Our mission was to create an orthomosaic starting only with the image sequence from a UAV flight. Typically this data is not highly calibrated; the camera characteristics may not be known and motion sensor data may not be present. Structure from Motion (SfM) offers a photogrammetric method for creating 3D models out of overlapping aerial imagery. This model in turn can be draped with the images to produce our orthomosaic.

Texas birds, fish, and water quality - My first adventure using FOSS4G to create an application visualizing data along the TX Coast

This presentation is about my first adventure in using FOSS4G web mapping technology to visualize and disseminate data. The technologies used include leaflet, mapbox, openstreetmap, bootstrap, and c3.js(charting wrapper for d3.js).

Transportation GeoDesign using Open Data & Select Open Source Tools.

This presentation will share the workflows and tools that are being used on transportation projects to deliver state of the practice 3D modeling technologies in a fraction of the time and budget of traditional approaches. Common programming languages such as Java, JavaScript, VBA, and VB .NET are being used to connect people and share invaluable resources.

Cartography with Inkscape

Sometimes your map needs a little extra polish. In this talk, I will outline my workflow for bringing maps from QGIS into Inkscape and exporting to commonly used formats to produces a finished professional-quality map. It will include "do's" and "don'ts" to help you develop your own workflow and avoid common pitfalls, as well as some features unique to Inkscape such as filters.

Introduction to GeoServer

GeoServer is an open source server that allows users to share and publish spatial data over the web.

In this tutorial, attendees will learn how to load, publish, style, and share spatial data with GeoServer. Discussion will include navigating the GeoServer user interface, loading and publishing data, OGC web services, and styling.

The workshop is geared toward those with no prior GeoServer experience, but familiarity with basic GIS concepts is suggested.

Make a web app from start to finish with Mapbox

Javascript maps are everywhere and the tech powering them is changing all the time. This four-hour workshop will walk you through how to take your idea for an awesome web map design put it on the web using the latest open source tools, specs, and APIs from Mapbox. We'll focus on GL-powered maps using Mapbox GL JS, the Mapbox GL Style Spec, and data from OpenStreetMap. We'll discuss how GL maps differ from popular raster tile-driven mapping libraries like Leaflet and the Google Maps API.

I see NoSQL document stores in geospatial applications (sponsored by IBM)

IBM Cloudant describe the geospatial tools used in their database-as-a-service offering (DBaaS). Based upon Apache CouchDB, the geospatial extensions used by IBM Cloudant rely on a number of well known open source libraries to provide geospatial indexing, query and projection support to Apache CouchDB. Presented at last years FOSS4GNA the tools are operational, and being actively supported and developed.
