Overcoming Open Source and Proprietary Data Interoperability Challenges

Session Type: 
Tech Session
Presenter(s): 
Dale Lutz, Safe Software

With so many new open source solutions available, organizations are now looking for ways to easily integrate their proprietary data into these open source environments. Accessing and preparing spatial data from a variety of systems can be a challenging and time consuming process. With spatial data transformation software, users can overcome these data interoperability challenges and be able to transform data regardless of its originating format or system. With examples, this session will illustrate how a user can quickly access spatial data gathered from any source, open or proprietary, and then make it available in their system of choice. Attendees will learn how they can make spatial data more readily available within their organization and learn best practices for overcoming data interoperability challenges. The goal of this session is to demonstrate that spatial data, open source and proprietary, can be made available for an organization’s decision making and planning.

Dale has been using his knowledge and experience to lead the core development of FME since Safe Software's inception more than 17 years ago. Much of Dale's time is spent refining and optimizing the user experience in FME's graphical user interfaces, as well as leading the integration of FME technology into third-party GIS applications. Known for his expertise in data interoperability, Dale continues to help Safe's customers find better ways to access the spatial data they need to use.

Mapnik2GeoTools

Session Type: 
Tech Session
Presenter(s): 
Mr David Winslow, OpenGeo
Mrs Alyssa Wright

For years, Mapnik has been the cartographic tool of choice for web designers. Sometimes however a web map requires more than rendered tiles. It requires the power of a complete geospatial service. Wouldn't it be nice to bring Mapnik's design prowess into GeoServer's full-featured, batteries-included management interface and standards-compliant services? Now you can!

In this talk we introduce mapnik2geotools -- a configuration importer from Mapnik to GeoServer. We will sample renderings from Open.Mapquest.com Mapnik styles and data from OpenStreetMap, compare the quality and styling options of Mapnik and GeoServer's rendering engines, and discuss future directions for the toolkit.

Speaker Bio: 

David Winslow is a software developer at OpenGeo working on GeoNode, GeoServer, OpenLayers, and GeoExt as the task demands. Some of his other projects include the GeoServer CSS extension and the Scala variant of GeoScript.

OpenAerialMap: Free Imagery for the World

Session Type: 
Tech Session
Presenter(s): 
Schuyler Erle, SimpleGeo, Inc

OpenAerialMap is an effort to produce and Free and Open archive of satellite and aerial imagery spanning the entire world. This talk will cover the origin and motivations of the project; how to access and contribute to OpenAerialMap; and how OSGeo software makes the project possible. I've been talking about this since OSGeo 2005 -- and now it's a reality!

User Friendly Open Source WPS

Session Type: 
Tech Session
Presenter(s): 
Bastian Schaeffer, 52North

Spatial Data Infrastructures have evolved from concepts to reality in the last decade. However, they are still focused on data retrieval and visualization. To proceed in the direction of a true Spatial Information Infrastructure, it is evident to take the processing of geodata into account.

The OGC Web Processing Service Interface (WPS) is the most promising standard to address geoprocessing in a standardized manner.

Several free and open-source WPS implementations exist. However, a common requirement to use most of them is a deep technical knowledge in terms programming or at least low-level configuration in various technical files and format (command lines, undocumented configuration options, compilation, python scripting, xml, yaml, make files, ant files, maven files etc, etc.). User friendly configurations or even out-of-the box usage of a wide variety of Geoprocessing functionality is not supported yet in most cases.

This presentation shows the new features of the 52°North WPS:

  • WPS Installation via an Installer
  • RESTful Bindings
  • Visual selection and configuration of WPS processes from a large set of available processes coming from the FOSS GIS packages GRASS, SEXTANTE, ArcGIS Server, Python and R.
  • Execution of Processes via OpenLayers
  • Direct Storage of results in a WMS/WFS/WCS

Web-Based Geoprocessing - Quo Vadis?

Session Type: 
Tech Session
Presenter(s): 
Bastian Schaeffer, 52North

Several Vendors have implemented the OGC Web Processing Service specification and made it available as open-source; closed source vendors went the same path; several (research) projects have been conducted and first operational services are available.

But where does this all lead to? Quo Vadis web-based geoprocessing?

This talk reviews current efforts in this direction. In particular, several real world use cases for Geoprocessing on the web by means of standardized web services (i.e. WPS) are collected and shown. The use cases are categorized to identify general vendor-independent WPS application domains. Conceptual and technological gaps are identified on this basis. From a technical point of view, inside is given into the upcoming OGC WPS 2.0 specification.

On this basis, a future vision is outlined with a special regard to open source software for the transition from a desktop driven to a web-based driven Geoprocessing landscape to turn Spatial Data Infrastructures ultimately into real Spatial Information Infrastructures with on-demand and ubiquitous access to Geoprocessing Services and resources.
