geomap – A new, open-source JavaScript mapping API

Session Type: 
Tech Session
Presenter(s): 
Mr Ryan Westphal, Applied Geographics

More than ever, users expect to interact with maps on the Internet. Developers need lightweight and capable ways to integrate interactive maps with their websites.

Applied Geographics has been solving web mapping problems for over six years. In this time, we have created solutions for displaying geographic data from different servers simultaneously, allowing users to interact with that data comfortably and giving developers ways to streamline their code.

This presentation will discuss these mapping problems, some of the existing open-source solutions and how our approach has produced the foundation of a new, open-source JavaScript mapping API.

Speaker Bio: 

Ryan has been professionally developing mapping websites as well as client & server GIS tools for the past five years. He loves HTML & JavaScript <3

Techniques for distributed high-speed map tile generation using Mapnik & Node.js

Session Type: 
Tech Session
Presenter(s): 
Simon Tokumine, Vizzuality
Javier De La Torre

Map tile generation can be monolithic, hard to scale and optimise. We present a decoupled open source approach that levers asynchronous highspeed V8 server side javascript with the Mapnik mapping toolkit to generate interactive and queriable data layers for your mapping application.

Speaker Bio: 

Simon is a technical lead at Vizzuality where he is busy working on various geospatial projects. He has a particular interest in developing simple, scalable solutions to common mapping problems.

Enhanced Support of OGC's Web Coverage Service (WCS) in MapServer 6.0

Session Type: 
Tech Session
Presenter(s): 
Stephan Meissl, EOX IT Services GmbH (S. Meissl, F. Schindler)
Frank Warmerdam, Independent

MapServer 6.0 is the first widely used web mapping software providing a WCS 2.0 server implementation. The new download standard WCS 2.0 was adopted by the Open Geospatial Consortium (OGC) in August 2010. WCS 2.0 support is included in the new version 6.0 of MapServer, among a long list of improvements, including also support of XML/POST protocol binding in WCS 1.1.

This presentation puts focus on technical aspects of the implementation and will include tips, tricks, and examples for the real world usage of WCS in MapServer focusing on the new version 2.0.

WCS 2.0 uses a coverage model which is based on GML and harmonized around OGC working groups thus allowing the usage of coverages interoperably and independently from a particular service. WCS 2.0 is defined as a modular, structured suite of specifications fitting into an extensible overall concept. The properties defined in the core (mainly consisting of coverage retrieval, sub-setting by trimming and slicing) must be offered by any conformant implementation. Extensions add optional further functionality like protocol bindings or format encodings.

Speaker Bio: 

Stephan Meissl works in Austria, Europe as co-founder of EOX IT Services GmbH. He gained experience in various projects funded by the European Space Agency focusing on on-line data access to Earth Observation data. He is actively participating in OGC's Web Coverage Service (WCS) Standards Working Group. His Open Source involvement includes active contributions to OSGeo's MapServer project and initiating the EOxServer project. He graduated as Master of Science in the field of Mathematics in Computer Sciences from the Vienna University of Technology.

Frank Warmerdam has been a contract geospatial software developer focused on data access and interchange since 1998. He is the founder of the GDAL/OGR project, and contributing to projects such as MapServer, PROJ.4, OpenEV, libtiff and libgeotiff. He is a founding member and director of the Open Source Geospatial Foundation (OSGeo). He is a graduate of the University of Waterloo, with a honours BMath majoring in Computer Science.

WorldMap: a GIS web application for collaborative research built on the GeoNode platform

Session Type: 
Tech Session
Presenter(s): 
Matthew Bertrand, Harvard University
Benjamin Lewis

 

WorldMap is a web-based geographic data exploration system that is built on open source technology.  It is designed to be publicly accessible, simple to use, and rich in content.  Its first implementation in 2008 proved to be an effective solution for integrating dispersed geographic data collections to allow for cross-disciplinary academic research. The Center for Geographic Analysis at Harvard University has designed a 2nd generation of the system, based on the open source GeoNode platform.  GeoNode brings many functional improvements to WorldMap that facilitate greater scholarly collaboration, such as the ability for users to upload their own geographic data,  control who can view or edit that data, and display the data on customized maps.  WorldMap also adds new functionality of its own, including enhanced search and query capabilities for map layers, PostGIS integration, and additional map creation features.  WorldMap is able to integrate an ever expanding data collection from local and remote sources. It gives users the flexibility to focus on any particular theme on any geographic extent (from the entire world to a city neighborhood), and its interactive tools allow users to discover, combine, and visualize materials from different sources and formats.

 

Speaker Bio: 

Matt is a GIS Programmer at Harvard University's Center for Geographic Analysis. His main interests include development of web mapping applications and scientific uses of GIS.
