Re: [OSGeo-Discuss] Correct List for Newcomers
The qgis georef plugin is good with a few regrettable UI odditys. (QGIS 1.6 WIN). 1. It essentially uses brute force to distort the raster to try to make your grid control points match. If you know the projection of the source raster then there are better ways see below. 2. A trap for young players is that any method but linear will distort the raster, ie rotate or squish. None of this is made clear by the plugin. 3. For some odd reason you cant paste coords into the UI. Odd because who remembers and types 9 digit numbers. 4. Try to get an accurate vector layer of the same terrain, that has recognizable locations that match your raster, load that up, and then use the from map tool, itll be the easiest way. Now if you know the projection of the source raster, why mess around with it. Use the QGIS | raster | warp tool which warps between two mathematically known projections, and not introduce any more noise, and assigns the source srs, and converts to geotiff all in one action. One newbie to another mate. Theres lots to learn, allow some time or youll find it frustrating.

[OSGeo-Discuss] osgeo4w installer workaround
Thanks to Matt Wilkie from the osgeo4w list, there is a workaround (some will use it probably as primary :) ) way to get the osgeo packages installed even from those networks that are currently not permitting connection to the main osgeo download server (example is Telecom in Italy).

Bob, To georeference your images, you could use an online app like Map Warper: http://warper.geothings.net/ Or, you can use one of the georeferencing plugins for QGIS. Here is a blog post that talks about using QGIS for georeferencing: http://geo.distortions.net/2010/11/georeferencing-with-gdal-17-and-qgis-16.html Here is a .pdf of a lab demo on georeferencing using QGIS. http:// courses.umass.edu/nrc297s/PDFs/Lab_Georeferencing_with_QGIS.pdf For specific help on georeferencing using QGIS, I would contact the QGIS-User list.

Bob, You might want to look at the Perry-Castaneda Library, University of Texas at Austin. Here is a link to their historical maps. http://www.lib.utexas.edu/maps/historical/index.html There are actually a ton of WWII era maps of the Pacific. According the the FAQ, most of the maps are in the Public Domain. http://www.lib.utexas.edu/maps/faq.html (Of course, verify that the terms of use match your needs.) You may have to georeference the maps yourself.

But no, this probably isn't the right place to ask about a specific computer application. However the direction we send you is going to be based on which software you were referring to in your post, could you please clarify what software you are using so we can direct you to the more appropriate list on that? Of the course the other approach is to more generally ask what software should you be using for your particular use case? That sort of question is very appropriate for this list. I find the question of finding period accurate maps of WWII in a digital form a very intriguing question, and would love to hear what others have to say on the topic.

[OSGeo-Discuss] Für Kurzentschlossene: FOSSGIS 2011 - Treffen der GIS Co mmunity in Heidelberg vom 5.-7. April 2011
Sehr geehrte Damen und Herren, nun sind es nur noch wenige Tage bis zur FOSSGIS Konferenz in Heidelberg. Für Kurzentschlossene besteht auch jetzt noch die Möglichkeit zur Anmeldung. Neuigkeiten und Hintergründe zu Technologien des Geo-Webs / GIS-Applikationen mit Freier Software und Freien Daten werden vom 5.-7. April 2011 in Heidelberg präsentiert. Die größte deutschsprachige Anwenderkonferenz für Freie Geo-Informationssysteme und Freie Geodaten wird 2011 wieder einen zusätzlichen Schwerpunkt zu OpenStreetMap haben. Der Themenbogen spannt sich von fußgängerbezogener Datenaufbereitung in OSM über Geodateninfrastrukturen bishin zu Technologien zur Prozessierung von umfangreichen Geodaten und spiegelt damit den Trend der steigenden Durchdringung des Internets mit Karten und Geodaten wider. In mehr als 60 Vorträgen für Einsteiger und Experten, Hands-On Workshops und Anwendertreffen erhalten die Besucher Einblick in aktuelle Anwendungsmöglichkeiten und Neuigkeiten von Softwareprojekten, die derartige Anwendungen ermöglichen. Über die gleichzeitig stattfindende Firmenausstellung ist ein direkter Kontakt zu Dienstleistern, die professionelle Unterstützung bieten, möglich. Zusätzlich zum fachlich orientieren Austausch in Community-Sessions und Entwicklertreffen findet ein Social-Event statt, um den Austausch aller Beteiligten - vom Benutzer über Entwickler und Mapper bis zum Entscheider - zu intensivieren, um gegenseitig von Ideen und Herausforderungen zu lernen. Die Konferenzgebühr beträgt für die gesamten drei Konferenztage 120,- . Auch in diesem Jahr können wieder zahlreiche Workshops besucht werden für die eine Teilnahmegebühr von 100,- je Teilnehmer und Workshop erhoben wird. Workshop-Teilnehmer erhalten eine Teilnahmebestätigung für die besuchten Workshops. Die Einnahmen gehen wie auch in den Jahren zuvor vollständig in die Finanzierung der Konferenz ein. Das Anmeldeformular und andere organisatorische Informationen befinden sich auf der Konferenzseite http://www.fossgis.de/konferenz/2011/. Die FOSSGIS Konferenz 2011 wird vom gemeinnützigen Verein FOSSGIS e.V, der OpenStreetMap Community und der Open Source Geospatial Foundation (OSGeo) in Zusammenarbeit mit der Abteilung für Geoinformatik des Geographischen Institut der Universität Heidelberg veranstaltet.

If I understand your question correctly, then teh concept you are describing is commonly known as "seeding the cache". Probably any other tile caching software out there has a seeding utility.
