12:57:42 vmx: can any of the osgeo guys please run the sync script for the foss4g website? TylerM perhaps?
13:07:57 TylerM: vmx: done
13:08:11 vmx: thanks
13:08:19 TylerM: wildintellect: i've got more 2007 annual reports printed, want some?
13:16:45 darkblue_B: hello - I was idley considering what might be a representative slice of OSGeo activity to display.. I am looking at the OSGeo-Software-and-Data-Projects page on Nabble.. credit to Jason Birch whose smiling face occurs at the bottom
13:16:47 TylerM: vmx: seems the "web-banner-square.jpg" I was referring in our osgeo web site is gone?
13:17:01 : * TylerM waves at brian
13:17:06 darkblue_B: hi TylerM
13:17:24 darkblue_B: dont let me interrupt.. just ad-hoc internet time :- )
13:17:35 TylerM: not much going on here : ) carry on soldier ; )
13:18:37 vmx: tylerm: it should still be in the web folder ( but not in the documents folder )
13:18:44 darkblue_B: the Java side of thing.. GeoTools.. isnt on the Nabble site
13:18:57 darkblue_B: but quite a few other things are..
13:19:01 TylerM: vmx ok
13:19:07 vmx: tylerm: you should upgrade to the 125x125 logo ( if that's possible )
13:19:17 TylerM: i just did thanks
13:19:23 vmx: great
13:21:41 darkblue_B: Ohloh search for OSGeo pulls in OpenStreetMap too
13:21:52 TylerM: darkblue_B: my stack doesn't : )
13:21:57 darkblue_B: a distinction needs to made gracefully there
13:22:00 darkblue_B: aha
13:22:05 darkblue_B: looing
13:22:23 TylerM: try http://www.ohloh.net/stacks/151
13:22:25 sigq: Title: Tyler Mitchell's Default Stack - Ohloh ( at www.ohloh.net )
13:22:38 TylerM: hmm, i better name it osgeo, so it gets picked up better
13:23:41 darkblue_B: stacks 151 - nice
13:24:11 TylerM: does 151 have any numeric significance? ; )
13:24:11 crschmidt: ohloh stopped following the OL svn about 6 months ago I
13:24:18 crschmidt: keep hoping something will magically h appen to make it work again
13:24:22 TylerM: hopefully not as much as my original account number : ) https://www.ohloh.net/accounts/666
13:24:24 sigq: Title: Tyler Mitchell - Ohloh ( at www.ohloh.net )
13:24:26 TylerM: :o
13:24:32 TylerM: crschmidt: hmm...
13:25:14 darkblue_B: well I was thinking about what to have front and center at the USGS
13:25:19 TylerM: crschmidt: i did find some of the admins on #ohloh at one point in time.. they might help.
13:25:31 crschmidt: ah, but then it wouldn't be magic : )
13:26:00 darkblue_B: the OSGeo front page is *ok* but something that shows activity might be fun.. you know, Web Two-point-oh
13:26:10 TylerM: yeah...
13:26:12 TylerM: crschmidt: heh
13:26:28 darkblue_B: I should think that OL would stand out for activity
13:26:36 darkblue_B: not good if ohloh isnt current on that
13:26:40 darkblue_B: Nabble is good for that
13:26:57 crschmidt: I don't think OL stands out for activity more than most OSGeo projects.
13:26:59 TylerM: darkblue_B: I've been working on a script with the ohloh API to help roll up stats in a more meaningful way.
13:27:14 darkblue_B: well, I was going to wip up a graph
13:27:18 darkblue_B: whip
13:27:22 crschmidt: GDAL, MapServer, and PostGIS are all more active, I believe
13:27:28 crschmidt: Of course, OpenLayers is more awesome.
13:27:33 crschmidt: So there is that.
13:27:36 TylerM: that's the spirit ; )
13:27:41 darkblue_B: I think OL should be hilited to USGS
13:28:06 crschmidt: I've never talked to USGS people who aren't well aware of OpenLayers; perhaps you have some specific goal in mind?
13:28:16 darkblue_B: but its not like there are editorial favorites, rather, reflection of real stuff out there
13:28:30 darkblue_B: USGS people -> well this is outreach
13:28:44 darkblue_B: so.. always moving beyond the core super-well-informed
13:29:10 darkblue_B: maybe everyone at the USGS OpenHouse will be there with OL
13:29:13 darkblue_B: I dont know
13:29:28 crschmidt: Well, Knowing about OL and being able to use OL are two different things
13:29:28 darkblue_B: just thinking out loud
13:29:35 darkblue_B: good point
13:30:00 darkblue_B: "How do I get started"
13:30:00 crschmidt: Many of the things that USGS does are inappropriate for OpenLayers
13:30:07 darkblue_B: sure
13:30:15 darkblue_B: I wont ever know what all they do
13:30:29 TylerM: I have a quick cross-browser test question....
13:30:34 TylerM: in footer here: http://www.osgeo.org/tyler
13:30:35 crschmidt: Nor I : )
13:30:36 sigq: Title: TylerMitchell's blog | OSGeo.org ( at www.osgeo.org )
13:30:40 TylerM: do you see the scrolling banner?
13:30:53 crschmidt: Yes.
13:30:57 TylerM: it's not done yet, but just don't want to waste my time further if it doesn't ; )
13:31:03 TylerM: crschmidt: thx, what OS and browser?
13:31:23 darkblue_B: Ubuntu 8.10 FF3 - yeah
13:31:33 TylerM: thx darkblue_B
13:31:39 crschmidt: TylerM: Safari3, FF3, OS X
13:31:48 TylerM: great
13:31:54 : * TylerM looks around for one of those windows users...
13:31:56 TylerM: ; )
13:33:07 wildintellect: TylerM, you can send whatever you want us to have at the booths( new copy of your book? )
13:33:42 TylerM: wildintellect: roger that. heh - still waiting for my book myself :P
13:33:55 TylerM: unbelievable :S
13:34:04 darkblue_B: wildintellect: you having stuff shipped to Davis?
13:34:17 wildintellect: in general we have in the past
13:34:26 darkblue_B: the long long history
13:34:28 darkblue_B: :p
13:34:43 wildintellect: well most of the materials live here, so it makes sense
13:35:06 wildintellect: over the summer I think a lot of events are bay area so we might see about leaving it all with you
13:35:14 TylerM: it sure helps to have an address to dump my propaganda to ;- )
13:38:15 wildintellect: TylerM, is the Journal ed 5 done?
13:38:26 TylerM: I'd rather not talk about it ;- )
13:38:30 TylerM: no, not done yet..
13:38:35 TylerM: got a bit too busy last week with finances.
13:38:48 darkblue_B: hows that dissertation going wildintellect ?
13:39:01 TylerM: good question ; ) shift the guilt back ;- ) hehe
13:39:13 wildintellect: at least my talk at CGS this weekend is related
13:39:26 wildintellect: I'm going to talk about spatialite and how I've been using it
13:39:33 darkblue_B: aha
13:39:37 darkblue_B: thats fun
13:39:37 wildintellect: for my research
13:39:38 TylerM: cool - wish I could be there
13:40:03 darkblue_B: I am wondering about spatialite.. I am using sqlite3 for my day job
13:40:24 wildintellect: the new qgis build with spatialite support is the last piece of the puzzle to make it acceptable to the GUI driven GISer
13:40:42 darkblue_B: is that trunk qgis ?
13:40:56 wildintellect: yes, I think it's also in 1.1 which is being packaged as we speak
13:41:04 darkblue_B: excellent
13:49:37 wildintellect: I guess I'll print Journal 4 for this weekend
13:51:27 TylerM: wildintellect: I can get some in the mail for you tomorrow, e.g. for where 2.0 or whatever.
13:51:52 wildintellect: if you already have them printed, sure
13:52:40 wildintellect: have you heard any feedback about changing the marketing meeting time?
13:54:29 TylerM: yes, just picked up from printers.. snazzy colour cover.. great quality.
13:54:42 TylerM: No one else has spoke up on the time change suggestions.
13:54:59 wildintellect: makes me wonder if anyone else will show up
13:55:06 wildintellect: since it's just been us the last 2 times
14:45:36 pramsey: help from the masses: geographic trivia, _______'s Law, the idea that things near each other tend to be similar?
14:45:48 : * pramsey plays the Jeopardy theme.
14:46:05 darkblue_B: similarly bad - Murphy
14:46:23 darkblue_B: faster -> Moore
14:47:05 pramsey: found it http://en.wikipedia.org/wiki/First_law_of_geography
14:47:06 sigq: Title: First law of geography - Wikipedia, the free encyclopedia ( at en.wikipedia.org )
14:48:36 darkblue_B: Waldo Tobler - of course ! ;- )
15:02:02 bish0p: ok, so i was just talking with some people about ESRI image server to do on the fly othro rectification... is this possible with some sort of osgeo products?
15:03:52 bish0p: on the fly part.. not actually being required
15:06:50 wildintellect: what orthorectification
15:07:22 crschmidt: bish0p: as I understand orthorectification, it is a process that requires someone to manually enter in gcps and associate them to an image.
15:08:49 wildintellect: bish0p, did you want to do it in a desktop app or via a website/server?
15:08:52 bish0p: yeah, this would be more of a on-the-fly dingbat product.. which would be tossed when the later properly ( gcps involved ) is delivered
15:09:25 wildintellect: you mean like guess based on the center point coordinate and elevation
15:09:35 bish0p: wildintellect: in a server - service would be a WMS
15:09:56 TylerM: with user choosing the common place on multiple images?
15:10:06 crschmidt: bish0p: I'm not sure I understand how something can be rectified without data matching, or a human matching
15:10:12 bish0p: wildintellect: yeah, just a silly : ortho-ready product + DEM - no GCP/user clicking
15:10:41 bish0p: crschmidt: yeah, that is what I thought, but apparently ESRI's Image Server is offering this feature.. which to me means it is just faking something..
15:10:57 crschmidt: Or perhaps someone doesn't understand what they're dealing with...
15:11:00 : * bish0p doesn't want to get sucked into having to start serving data from ESRI Image Server.
15:11:14 crschmidt: Sounds to me like a miscommunication.
15:11:18 bish0p: yeah, probably should do some more research of what it is ESRI is actually doing
15:11:26 TylerM: Sounds more like warping to fit topography using imagery that's already clearly registered
15:11:40 crschmidt: Well, that can be done with Open Source software
15:11:49 crschmidt: vis http://labs.metacarta.com/rectifier/
15:11:50 sigq: Title: Map Rectifier - by MetaCarta Labs -- A web-based map rectification tool ( at labs.metacarta.com )
15:11:56 TylerM: Like the process to do the orthorectification, but where GCP are already known : )
15:12:56 bish0p: ahh, rectifier, that looks promising.
15:15:50 pramsey: orthorectification is more than warping to fit
15:16:27 pramsey: an orthophoto is one where every pixel is a nadir observation, looking straight down. which, from a reality-based PoV is impossible
15:16:49 bish0p: yeah, i'm looking for a ortho-warping product i guess
15:17:13 pramsey: but using an aerial photo, knowledge of the how the lense in the camera works, and the ground topography ( hills, etc ) it's posisble to make one with math
15:17:30 pramsey: back in the good old days ( tm ) they did it with amazing optical machines
15:17:49 TylerM: i think you're simply looking for 'rubbersheeting', that more accurate pramsey ?
15:18:00 bish0p: what i've got is a vendor delivering an ortho-ready product to be archived and then later that will be cleaned up into a proper orthorectified product.. but between the two deliveries we'd like a WMS of 'just winging it for now so you can see pixels but holycow don't build anything based on this' layer
15:18:06 pramsey: that's what the "rectifier" at labs. does, yes, TylerM
15:18:16 pramsey: "rectifier" is a bit over-named.
15:19:10 wildintellect: bish0p, if it's ortho-ready then it should already be georeferenced
15:19:13 pramsey: BTW, OSSIM ( osgeo project ) can do terrain correction. It also had some GCP hooks, though I am not sure what their current state is.
15:19:28 pramsey: er, terrain correction and also sensor correction
15:19:39 pramsey: last time I researched the GCP stuff was two years ago
15:19:46 pramsey: so it could be quite usable at this moment
15:20:02 bish0p: wildintellect: yes, geo referenced. the issue we have where I am is that we have bad DEM data and we want to be able to revisit stuff when we get better DEM data
15:20:47 wildintellect: so do you want to orthorectify using the current dem and then serve the result
15:21:05 wildintellect: or just overlay them on top of each other
15:21:23 bish0p: yeah, orthorectify on a 'what we got' DEM
15:21:42 bish0p: which in house is the USGS NED.. horrible stuff up here in Alaska
15:22:54 wildintellect: so maybe OSSIM, or GRASS
15:23:09 wildintellect: with GRASS you can make it a service via pywps I think
15:23:31 bish0p: ahh, there we go
15:23:47 wildintellect: http://grass.itc.it/grass64/manuals/html64_user/i.ortho.photo.html
15:23:49 sigq: Title: GRASS GIS manual: i.ortho.photo ( at grass.itc.it )
15:23:56 bish0p: i noticed GRASS did this but I didn't know I could service it up if I was more leet in GRASS
15:24:32 bish0p: thanks - ok, so this gives me a direction to go.. got plenty of time to try to come up with my own solution before this ESRI thing comes up.. so time to experiements
17:40:19 sigq: osgeofeed: Changeset [1542]: added mapgears <http://trac.osgeo.org/osgeo/changeset/1542>
