Development

From Project to Product to Open Source. Now What?

Session Type: 
Tech Session
Presenter(s): 
Christine White, Esri Inc.

What started off as a project for a single customer, became a commercial product, and has since October 2011 been available as the open source Esri Geoportal Server. This presentation will discuss what motivated the evolution that has led to the Geoportal Server and will highlight some of the current developments, including new trends like linked data, semantic Web, and sensor web. How do these affect the discovery process?

Speaker Bio: 

Christine White is a product engineer for the open source Esri Geoportal Server and the open source ArcGIS Editor for OpenStreetMap projects. Her current work and research interests are in helping organizations define and implement systems for sharing their spatial data. She likes to see GIS used to develop solutions for the ecological & social challenges this – our – generation must take on

Crowdsourcing Aerial Image Mapping with MapMill.org and Cartagen Knitter

Session Type: 
Tech Session
Presenter(s): 
Jeffrey Warren, Public Laboratory
Adam Griffith, Public Laboratory

Increased participation in neogeographical aerial image mapping techniques such as kite, balloon and other unmanned aerial systems has shown the need for open source tools to work with the data. The imagery acquisition field techniques introduce remote sensing to a host of new users that are able to interact with data in ways previously made impossible by cost, education, and ease of acquisition of imagery. Mapmill.org and Cartagen Knitter are presented as crowdsourcing tools for sorting through raw flight data and rectifying the imagery. Participation in the sorting is easier than image rectification, thus separation of the tools.

Mapmill.org works towards sorting and organizing raw flight data in a simple web application. Imagery is interactively displayable in different fields and users sort through raw data by assigning values to separate images that are accumulated.

Cartagen.org Knitter works to rectify aerial imagery by warping the data dynamically in overlay with base orthoimagery data in a web application. The resultant map is viewable at Cartagen.org and GIS exportable. These tools work together towards participatory mapping at the community level.

Speaker Bio: 

The creator of GrassrootsMapping.org, Jeff Warren designs mapping tools, visual programming environments, and flies kites as a fellow in MIT's Center for Future Civic Media, and as a student at the MIT Media Lab‚Äôs Design Ecology group, where he created the vector-mapping framework Cartagen. He co-founded Vestal Design, a graphic/interaction design firm in 2004, and directed the Cut&Paste Labs project, a year-long series of workshops on opensource tools and Web design in 2006-7 with Lima designer Diego Rotalde.

Applying the Open Geo-Stack to Web-enabled Things

Session Type: 
Tech Session
Presenter(s): 
Arne Bröring, 52 North
Damian Lasnia

Applications of the Web of Things reach from smart shoes posting your running performance online, over the localization of goods in the production chain, to computing the insurance cost of cars based on the actually driven kilometers. Thereby, Web of Things applications follow the REST paradigm, i.e. access to things and their properties is offered via REST APIs. This allows an easy meshing of web-enabled things into existing Web applications.

We present the SenseBox, a small computing device equipped with (1) different sensors to perceive its environment and (2) with a Web server and an according REST API which makes it available as a first class citizen on the Web. In an example use case, the SenseBox is deployed next to a road and its in-built ultra sonic sensor is used to detect the number of bypassing cars and eventually determine the traffic density.

The portal to access those SenseBoxes and display them in their spatial context is based on the open geo-stack consisting of OpenLayers, GeoServer, and PostGIS. We demonstrate how the integration of such Web-enabled things with these software tools works.

Geomajas, a GIS framework for the web

Session Type: 
Tech Session
Presenter(s): 
Joachim Van der Auwera, Geosparc

Geomajas, a GIS framework for the web, focusses on efficient data delivery, security and performance. The mantra is "integrate, transform and secure GIS data". It is cloud-ready and modular, has advanced caching and security. The framework can talk to many types of data sources and present them in several ways using our "faces".

Speaker Bio: 

Joachim Van der Auwera is a software consultant with a strong focus on building quality software with lots of reusability and which is highly maintainable. He has been using Java for more than 10 years. In this period he was involved in both architecture and development of enterprise applications. He has a lot of experience with open source projects and is part of the three-headed dragon leading the development and architecture of the Geomajas GIS spatial data and web mapping framework. His achievements in the project include the security architecture, plug-in mechanism, API contract, documentation system etc. He has more than 10 years Java experience, mostly for enterprise projects.

Securing GIS data

Session Type: 
Tech Session
Presenter(s): 
Joachim Van der Auwera, Geosparc

Implementation and architecture of security on GIS data as implemented in Geomajas. Details are given about possible use-cases, the choices which were made (including why). It includes explanation of how credential leakage is prevented and how this can be integrated with industry standard solutions.
