The Intersection of Geospatial and Business Intelligence

in FOSS4G, FOSS4G2011, Video, OSGeo
OSGeo

Business intelligence (the techniques used in identifying, extracting, and analyzing business data) is a massive market and a vibrant area of research and development for many companies. The incorporation of true geospatial data and analysis is still a new facet in the field and one that is expected to experience significant growth and evolution in the near future.

The goal of this talk is to discuss the current state of the open-source solutions, discuss the strengths and short comings of the current solutions and look at avenues for improvement and opportunity.

A few of the technologies that will be touched upon will include:

  • Olap4j
  • Geomondrian
  • Geowebbi
  • Spatialytics
  • Pentaho
  • Mondrian

Some axes of discussion:

  • Types of Queries
  • Types of Reports
  • Supported Standards
  • Supported Data Sources
  • Role in ecosystem
  • Interoperability
  • Architectures
  • Performance

Turning Data into Beautiful Maps

in FOSS4G, FOSS4G2011, Video, OSGeo
OSGeo

Data experts can now become mapmakers without picking up GIS expertise first. This session will walk through how to leverage emerging open source tools to design highly custom maps for use online and on mobile devices - without GIS experience.

This session will start by looking at the current ecosystem of open source mapping technologies and the possibilities with the growing open data movement and market demand for location awareness. Then it will look at one tool specifically - TileMill, an open source map editor that makes it easy to design and generate beautiful custom map tiles for users with basic web HTML/CSS fluency.

This session will walk through how to use TileMill to create custom maps, starting from combining spreadsheet data with open data shapefiles to editing the map design using Carto, a CSS like language to adding new data overlay using your own or open data sets. It will then show how to take a custom interactive map, host it, and use it either on a website or on a mobile device. By the end of the session, participants will have seen at least one map created from scratch using TileMill in use on a website and ipad.

This session will also discuss the open source technologies at TileMill's core - Mapnik, which renders the map, and Carto, the map styling language. These projects and others are the basis of TileMill, so the presentation will also focus on their individual characteristics as well as how they fit into a user friendly package. The centerpiece, however, will be teaching participants how to use the tools to create and use their own custom maps.

Tuning GDAL Raster Performance

in FOSS4G, FOSS4G2011, Video, OSGeo
OSGeo

Web mapping performance is often constrained by the speed of access to the underlying geospatial data. A comparison of different file formats, image organization techniques, compression, caching and other factors will be discussed in the context of their impact on performance for raster data access intensive applications. Results will be presented for the particular case of web mapping with MapServer on top of the GDAL raster data access library.
