An open source geo-transformation library for data custodians. The KMStrlib geo-transformation library, which has been in active use and development since the 1960s at KMS (National Survey and Cadastre, Denmark), is now finally being released under an open source licence.

KMStrlib provides a unified interface to a large number of cartographic projections, and geophysical transformations (including change of vertical and horizontal datums and epochs).

Due to KMS's role as a long term geodata custodian, care has been taken to ensure that the transformations implemented are two way symmetric (to the extent possible: some transformations are inherently vaguely defined, and must be implemented by stochastic predictions, rather than projections). This has led to the adoption of a technique of dual self-checking transformations, effectively doing a roundtrip "forward-inverse" operation for all library calls. While elaborate, this ensures that uncaught implementation blunders, and asymmetric singularities are diagnosed and reported. This is essential for long term (multiple century scale) geodata interoperability.

The poster presentation will include schematic details of the dual self-checking procedure, and illustrate the characteristics of the KMStrlib implementation of a fast, highly precise transverse mercator projection, remaining accurate at the 0.03 mm level even at distances 7500 km from the central meridian.

Quality control of digital elevation models. In this poster presentation, we describe how the PINGPONG program (FOSS distributed under the GPL) has been used to implement a quality control procedure for laser scanned DEMs. The approach used is independent of navigational (GPS/INS) data and ground control points.

Fundamentally, PINGPONG is a high speed gridding program for scattered geodata. It uses a simple, but efficient, data management technique to speed up the gridding procedure.

The speed of PINGPONG makes it feasible to include a large amount of gridding in our quality control procedure, even for national scale datasets (in our case involving in the order of 20 billion data points), so the procedure is based on analysis of the local difference of a digital surface model, and a digital terrain model.

Effectively, this means that we are generating two interim elevation models in order to test one point cloud for its suitability for generating a final model. While this may seem somewhat extravagant, experience shows that it is actually both useful and efficient.

INSPIRE compliant geoservices for topographic databases of the Lombardy Region in Italy. Aim of the work is the implementation of geoservices compliant with the European INSPIRE Directive for distributing Lombardy Region geotopographic databases at scale 1:2000.

The services are based on OpenGIS Catalogue Service Implementation Specification (CS-W 2.0.1) and OpenGIS Web Map Service (WMS 1.3.0) Implementation Specification as required by the Directive itself. They were implemented with Open Source Software: UMN Mapserver for WMS service and Geonetwork for metadata handling (CS-W). Test data used for the prototype are compliant with the Standard for modelling geographic data recently approved by the Lombardy Region (february 2008). The infrastructure is freely available for all territorial Authorities having such a kind of geotopographic database. A website with a demo version is already online (http://ows.como.polimi.it) and will be shown if an internet connection is available.

Electronic Tag Data Visualisation In 1981 CSIRO Marine and Atmospheric Research (CMAR) began development of a database to house data on conventional tagging of marine fishes. Since that time CMAR’s tagging projects have expanded and incorporated a wide range of tags from the simple conventional through to the latest electronic tags, and have began tagging marine mammals and birds. The amount of data being generated has vastly increased since 1981. CMAR has promoted a centralisation of tag data to ensure data are widely accessible, secured against loss, and to reduce redundancy amongst projects. One criticism of this approach has been a difficulty in data access within and across sites. Through the Electronic Tag Support Systems project CMAR has developed a web portal, using SVG, to the tagging database allowing users to browse through the electronic tag data and easily extract data of interest for further analysis. Tag tracks are displayed on an interactive map and archival data displayed in interactive graphs. Paavo Jumppanen, Jason Hartog, Scott Cooper CSIRO Wealth from Oceans Flagship
OldMapsOnline.org: Open Source & Online Tools for Old Maps OldMapsOnline.org is a research project targeted to the software development specialized to old map collections. We are designing online tools for collaborative georeferencing, annotation, 3D visualization, accuracy analysis and geometadata specification.

We provide free software and tutorials for online publishing of your scanned historical maps. We have developed IIPImage JPEG2000 Image Server: open source server software for fast delivery of the ultra high resolution raster imagery directly from your master scans in formats like JPEG2000 or TIFF. This software can be used for free on your servers for the image publishing. You can also publish your maps as pre-rendered tiles (zoomify) without any extensive configuration of your webserver. There is a whole collection of attractive pan&zoom viewers for the visualization of your scanned maps in your web sites - all viewers are compatible with both publishing techniques (JPEG2000/TIFF or prerendered tiles) - and they are mostly available including the source code, so you can easily customize them according your needs.

Once your maps are online you can use our web-based tools to georeference and visualize them in 3D with Google Earth web browser plugin. Your scanned maps can simply overlay each other as well as the popular interactive base maps like OpenStreetMap, Bing, Yahoo or Google Maps. You can even analyze their cartometric accuracy - all of this within the web browser.

Our project is in progress but we have already published several software tools and we have prototypes for the complete workflow. More info at http://www.oldmapsonline.org/

geo-spatial.org: The Reference Point for the Romanian FOSS4G community A geospatial portal is a human interface to a collection of online geospatial information resources, including data sets and services (OGC, 2004). geo-spatial.org is a collaborative effort by and for the Romanian community to facilitate the sharing of geospatial knowledge and the discovery and publishing of free geographic datasets and maps. It was created by a small team of young scientists as an attempt to overcome the Romanian specific geospatial dysfunctions.

Anyone can make a contribution by submitting articles or datasets for publication, adding comments to the existing articles, join the discussion on the mailing list or users forum. The content is managed by Textpattern, a powerful and flexible, open source content management application. For supplementary, specific functionality, custom modules were built. Other free applications are providing server-side functionality: MySQL (relational database management system), PHP, Python, Java (server-side scripting languages), Apache (webserver), Tomcat (servlet container), phpMyAdmin, phpPgAdmin (web clients for database management). For geospatial data processing and management, top open source applications were also integrated in the website: Mapbender (geodata management using OGC OWS architectures), PostGIS (is an extension for the PostgreSQL enterprise relational database, used to store the geospatial data), GeoNetwork Opensource (a standards based catalog application to manage spatially referenced resources), Geoserver (a standard compliant geospatial server, used to create specific services like WMS, WFS, WCS), OpenLayers (a pure JavaScript library for displaying map data), GeoWebCache (provides a Java-based WMS/TMS server, with pluggable caching mechanisms and rendering backends), Mapnik (render the base map), GDAL/OGR (used inside chained scripts for data conversion and reprojection). The website is divided in several functional sections. In each section, the information is placed in predefined categories and sub-categories. Most of the sections contains written materials: - Articles - theoretical essays on geospatial topics; - Tutorials - materials indented to teach the user, in a step by step manner, how to work with certain datasets, software, technique etc; - Reviews - reviews for geospatial datasets, cartographic products, software, articles, books; - Links - collections of references to other online resources; - Blog - a non conventional section for publishing thoughts, ideas, findings etc. The content of these sections can be accessed quickly via RSS and ATOM feeds. The Download section contains categories for all kind of geospatial data (digital elevation models, processed satellite images, vector data: communication networks, localities, hydrographical networks, contour lines, points of interest etc.) at different scales and spatial extend. Other categories contain documents (PhD thesis, scanned books & articles), old maps, software. The website interface was carefully designed, respecting the existing W3C (World Wide Web Consortium) standards and separating the structure from the presentation by using strict XHTML markup and CSS (Cascade Style Sheets). New web technologies, like AJAX (Asynchronous JavaScript and XML), were also used to increase the interactivity. The goal was to obtain a simple, friendly and accessible environment for geospatial data and knowledge publication.
