As open-source technology trends continue to emerge in modern IT enterprises, there has been significant interest from the geospatial community in implementing open-source GIS technologies. There are a multitude of reasons why organizations consider open-source, and in this discussion, Boundless will share best practices around a hybrid approach to integrating and implementing open-source geospatial technologies, alongside existing proprietary technologies and tools.
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.
HealthyCity.org is a community-based web mapping and open data platform that transforms how policy decisions are made by providing community organizations and advocates with innovative tools and methods to expose and resolve structural inequities. Communities throughout California rely on HealthyCity.org to map community conditions, demonstrate community needs, and create strategies and materials for engagement with local representatives and officials.
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).
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.
QGIS is perhaps one of the most powerful and successful Open Source Desktop GIS available today. On top of it's already impressive feature list it is very easy extend and control it using the popular scripting language Python.
This workshop is an introduction to using Python to get the most out of QGIS. Participants will be shown how they can use plugins and scripts written in Python to:
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.
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.
