Re: [OSGeo-Discuss] Is Your Project In OSGeo Labs?
Landon, others, A comment on the name OSGeo Labs. I just did a Google search with it and it brings up also the university laboratories that have been set up under the auspices of the ICA - OSGeo MoU. Thus it seems to mean two things, and it might be confusing - for example the Slashgeo.org tag OSGeo Labs is used for the university labs. The software stewardship (or how would you call it) is managed by the incubation committee and the university laboratory network is managed by, hm, the Board (no, it's not managed by the education committee as one would guess). This might be just a naming issue but I think it is worth noting. But I also think that there could and probably should be collaboration between these two initiatives.

Would it be good if opengeocoder joins forces with openstreetmap nominatim?

We have sine joined forces with pgRouting and are developing the code that is MIT-X algorithms, which can be bundled with pgRouting effectively making them dual licensed. OpenGeocoder.net appears to be Steve Coast @ Microsoft and not related to OSGeo stuff. http://wiki.osgeo.org/wiki/**OpenGeocoderhttp://wiki.osgeo.org/wiki/OpenGeocodernever got off the ground, but I have been working with PAGC over the last few years. Our big issue at the moment is addressing some serious performance issues when you scale up from county level data sets to national data sets. Basically it is just me and Walter, the developer, working behind the scenes on these technical issues. Once these are resolved I hope to see if we can some activity going again with this. On a side note, I have take the address standardizer from PAGC, built it as a library and wrapped it into a postgresql stored procedure extension. Based on that I have prototyped up a Tiger geocoder that works very well and is very fast. I'm still work on various things so it is not ready for prime time but this might eventually become OpenSource also. I'm not sure what it means or how you get a project like these in labs but these are mostly orphaned except I have an interest in them and will respond to queries about them.

Re: [OSGeo-Discuss] Is Your Project In OSGeo Labs?
HI Milo, There are various initiatives related to Geocoding and it would be good if could share insights and resources. Some of the projects are: http://www.pagcgeo.org/ http://www.postgis.org/ - has Tiger based geocoder http://wiki.osgeo.org/wiki/OpenGeocoder - list some of these and others http://geocoder.us/ http://www.opengeocoder.net/ - some Microsoft employee openstreetmap nominatim The big differences between the various projects are based primarily on three dimensions: 1. Sources data ie: Tiger only, OpenStreetMap data, any data 2. Language and Geocoding Strategy 3. Licensing Combining/collabation of efforts really depends a lot of the compatibility of these dimensions. Package DataSource(s) LanguageLicensing --- pagcMultiple C MIT-X Street segments parcels landmarks postgis Tiger pgpsql GPL2 geocoder.us Tiger Perl Perl nominatim OSM data??ODbl? - Pagc, postgis geocoder and geocoder.us all started out as Tiger data based geocoder and have expanded into other realms that use similar structured data. These projects have more in common with one another than any of them have with nominatim, unless I am terribly mistaken. That is not to say we should not collaborate only the data structures and strategies for querying them are very different. For example, I just wrote a custom geocoder taking a small amount of code from pagc and wrapping it into a pgpsql stored procedure and then wrote a query planner in pgsql to do geocoding. I was able to load 50M records derived from Tiger, and index them in 6 hrs on a slow 4GB linux box and can geocode a table 216K addresses in about 44 ms per record. This is conceptually similar to the processes imployed by the postgis geocoder and by geocoder.us and for that matter a 2-3 other geocoders that I have worked with in the past that were not open source, one of them being a geocoder I wrote that only worked with the old Tiger/Line data. I have looked at nominatim, a couple of times to try an understand the process, but it seems to be very tied to the OSM data structures and infrastructure. So if someone wants to setup a private nominatim service for a client, they basic need LOTS of iron, LOTS of disk, and need to mirror much/most?/all? of the OSM infrastructure. And the licensing needs to be approved by the client. If I want to create a geocoder that works with Navteq data for a client that has access to that data, it is pretty easy for me to load the data into PAGC, or the geocoder I just wrote, or even the postgis or geocoder.us code with a little massaging of the data. I'm not sure where I would start with the nominatim code. OK, I admit that the failure here is my knowledge about Nominatim and/or maybe that Nominatim/OpenStreetMap are not interested in solving the use cases that I presented. Sorry, I have gotten off on a rant. Back to your point about joining forces, I'm ok with, but I'm not sure where to start. I think I outlined the problem as I see it, but some additional information related to Nominatim could help me get beyond my biases if I can see how we can successfully collaborate.

Steve, Add to your list this one: http://www.gisgraphy.com/ I think it's a mix of lots of things but uses OSM and Geonames for data source as far as I can tell and backend PostGIS and I think Java Servlets for application layer as far as I can tell. LGPL v3 licensed it seems. I came across this one when I saw this post: http://gis.stackexchange.com/questions/23113/comparison-of-geocoding-solutio ns-such-as-gisgraphy-postgis-2-0 Hope that helps, Regina -Original Message- From: discuss-boun...@lists.osgeo.org [mailto:discuss-boun...@lists.osgeo.org] On Behalf Of Stephen Woodbridge Sent: Saturday, December 08, 2012 8:11 PM To: Milo van der Linden Cc: OSGeo Discussions Subject: Re: [OSGeo-Discuss] Is Your Project In OSGeo Labs?
