We chose to use Open Source Software and specifically UMN Mapserver for WMS service and Geonetwork for metadata handling (CS-W).
 
In order to publish the data we suppose to have shapefiles compliant with the last specifications approved by the Lombardy Region: “Specifiche Tecniche aerofotogrammetriche per la realizzazione del data base topografico alle scale 1:1000 e 1:2000” - Version 3.0 - december 2007, approved with DGR number VIII/006650 of 20/02/2008.
 
The infrastructure is freely available for all territorial authorities having a new topographic database compliant with the last regional specifications.
 
A website showing a demo version of the infrastructure is already online and it will be showed if there will be an available internet connection.

Revision as of 05:26, 3 September 2009

Note: Details on this wiki still need to be finalised, and is being modeled on FOSS4G 2007's Poster session. http://2007.foss4g.org/presentations/posters/

Posters will be accepted from Case Studies, Projects or Programs that are Geospatial and have a strong Open Source and/or Open Standards theme. Refer to http://2007.foss4g.org/presentations/posters/ for examples of posters from prior years.

Coordinators

  • Shoaib Burq < s a b u r q AT gmail.c om>
  • Antti Roppola <ha s t ur AT gmail.c om>

Format

  • Location: Posters will be shown in the Lower Parkside Foyer
  • Size: Posters are to be printed as portrait (A0 or A1).
  • Schedule: The FOSS4G poster session will be during morning tea breaks on Thursday and Friday. Poster presenters should plan to be near their posters to talk to viewers and answer questions.
  • Quantity: The FOSS4G poster session will have room for as many as 32 posters.
  • Acceptance: On topic Posters will be accepted "first come, first served" until there is no more room or the deadline passes.
  • License: Posters should be made available publicly in PDF format to be displayed on the FOSS4G website as per the timeline.

Printing

  • Contributors are responsible for printing their own posters. One option for printing posters close to the conference venue is the Ultimo/Darling Harbor Kwik Kopy

Timeline

  • Interested posters should add their

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.
