[21:04] okay, hi ! let's start then [21:05] DoRight: last week I was traveling, I should've rescheduled [21:05] went to open source conference at State Dept... they are quite interested in mapping [21:06] Get more resources for us? [21:07] there were some people making their own map tiles using CloudMade or MapBox, but we're not there yet [21:07] I think I can come back to it in a couple of weeks [21:08] also, got to meet some of the people behind http://grassrootsmapping.org -- they go beyond satellite maps by flying balloons [21:09] why? [21:10] higher-resolution, more recent, and can be open-sourced [21:10] they took great photos during the BP Oil Spill and now some of those are in Google Maps [21:10] how old are the satellite images [21:11] huh, that's cool. do they use GPS hand-held devices, or rely just on their photographs? [21:11] rrosso: they put thousands of photos online, and people vote on whether they're good quality... I will have to post a link to that [21:11] then they use US gov or Google sat maps to line them up [21:11] and "stitch" them together [21:12] introvert: if you have Google Earth you can find exactly how old their images are... it can be a few years [21:13] website to vote on photos http://mapmill.org/ [21:14] But if they use google data, does that keep it from being used in opensource? [21:14] wow. [21:14] You explained some of that the first week, but unsure. Maybe just my brain cells. [21:16] Yeah, gorgeous fotos! [21:17] DoRight: I agree, using Google would make it non-free. But if they're in the US they can use some USGS satellite maps which are free [21:19] hey I wanted to see how you all were doing with OpenLayers [21:21] The opengeo.org examples are pretty straight-forward [21:23] I'll post the OpenGeo.org link : http://workshops.opengeo.org/openlayers-intro/index.html [21:25] seanhorgan: what is the next step at the end of the OpenGeo tutorials? would it be helpful to post something like, how to load geolocated photos from Panoramio ? [21:26] it's beginning to make sense. I need to learn how to get it to work outside of jsFiddle. [21:27] introvert: you're running it locally, then? do any parts of the map appear? [21:28] let me check something ... [21:30] This isn't exactly along the topic, but I did add a open map of Catacamas to a blog - http://ElCaminoAlHogar.blogspot.com/ [21:34] ndoiron, it depends on the map. the only map I get working locally is the first opengeo example, global imagery. [21:35] DoRight: cool ! I'm glad to see you're using what you're seeing from OpenLayers [21:37] introvert: well that's good, that you have a colorful satellite map working. What's your web browser? We can debug it [21:37] ndoiron, epiphany [21:38] introvert, I can firefox, if u prefer [21:39] Firefox 4, you can do Ctrl+Shift+J. Less than that, http://getfirebug.com/ [21:39] plugin that throws a red flag if the JavaScript on your page derails [21:41] firefox, 3.6.13 with firebug [21:42] okay, are you familiar with firebug then? does it tell you anything that could help us get the map working? [21:42] no, I am not familiar with it. and I don't see anything useful at all. [21:43] in the world of javascript programming/debugging, firebug is an essential tool to get very familiar with it [21:43] Google Chrome has a developer mode (ctrl-shift-j) that is similar [21:44] if you click on the little bug symbol on the bottom right of your firefox window, it should split the screen with the bottom half showing the firebug console [21:45] click the Script tab, then the down arrow, to set JavaScript to Enabled [21:45] seanhorgan, I'll move learning firebug up the list. [21:46] Wow the text of the script is full of "Ā Ā Ā Ā Ā " on most lines along with the code. [21:47] could be a cut-n-paste problem from a rich-text editor (MS word, etc) [21:47] it was cut and paste from jsFiddle to emacs and/or gedit [21:48] does jsFiddle have a download method I missed? [21:48] it should be cut and paste [21:48] I used it fine. [21:49] trying again... [21:49] cut/paste [21:50] Yep, never used firebug before. Looks like a keeper. Thanx [21:50] DoRight: that's great! yes it's so good that Firefox has it with Ctrl+Shift+K, and like seanhorgan says, it's Ctrl+Shift+J in Chrome [21:51] * Firefox 4 has something similar built in, I mean [21:53] cut and pasting into gedit and emacs both give me Ās [21:53] can you easily strip them out? [21:53] sure [21:54] it's been years since I messed with emacs but i'm sure it is just a couple of keystrokes to global remove [21:54] I'm seeing online that it could be a UTF-8 issue [21:55] which I don't really understand, but throwing that out there if it helps [21:55] that's what I thought too...I've run into problems like that it was usually encoding [21:55] while we work on that... [21:55] any other questions, ideas? [21:59] I'm trying to host a page with a map that draws icons based on locations from a file [21:59] is it best to store the data in a json format? [22:00] here are some formats you can use: http://openlayers.org/dev/examples/vector-formats.html [22:00] i don't have a concrete example for you (yet), but I'd like to iterate through an array of points and plot them on the map [22:00] wait, the example link uses the formats for output [22:01] it does have GeoJSON for input. Try that format or KML, which people can view in Google Earth [22:02] can OSM handle KML? [22:03] OpenLayers yes [22:03] right... [22:04] wrong question ;-) [22:04] cool. so I can probably use that GeoJSON as input then [22:06] This looks like the example for you to try: http://openlayers.org/dev/examples/geojson.html [22:06] ok, here's what I have so far (from your OpenLayers walk-through, Nick): http://www.publicdatapublic.org/openlayers_exercise.html [22:07] got it, thanks nick [22:14] okay great [22:14] I think I just lost the last 20 minutes. I seemed to be connected, but nothing was coming this way? [22:15] ndoiron, you will post the chat? [22:15] i'm just spinning my wheels here. will someone send a file, the sets coordinates and displays the map, that works locally? [22:15] DoRight and introvert: I will post the chat and a working HTML / JS file [22:15] DoRight: it send that you logged off quite some time ago [22:16] and just to check - I am the only one with strange characters from cut/paste from jsFiddle? [22:16] Thanx, my cell modem/provider have issues [22:17] @introvert I can cut/paste fine. [22:17] introvert: if others are following the course and running into trouble, it will be good to post that you have the problem too [22:18] I will post a working file, too, so we'll see if that helps you [22:18] ok, once I see if I can figure out what caused it. [22:18] one approach is to cut-n-paste through a simple text editor as an intermediary [22:19] seanhorgan, which one do you suggest? [22:20] vi/m [grn] [22:21] Seriously, I just used the cut/paste of linux with no problem. [22:22] introvert, there are tons of good text editors. for the moment, you can just use whatever is on your computer - notepad, textpad, etc. [22:22] +1 on using vi [22:22] [grn] [22:23] thanks all, after a break I will go over what I did and see if I can reproduce it and I'll let you all know. [22:24] good luck [22:25] maybe post the file? [22:26] It would be good for me to try and debug it. [22:26] is there a way/place for us to post files? [22:27] on http://p2pu.org/webcraft/node/12927/document you can attach files when you post a document [22:27] pastebin.com [22:28] oh! that's handy. [22:29] @rrosso probably stated while I was 'away' virtually, but what about posting in the forum? [22:30] modem died, @rrosso what was handy? [22:30] http://pastebin.com [22:31] DoRight: Nick linked to the course material tab on the course home page, where we can add documents. (we can only start discussions on the forum) [22:31] Nick and Sean - thanks. is pastebin the same kind of thing as Diigo? [22:32] thanx [22:32] never used diigo...but I would use whatever Nick recommends for the course [22:33] ok, just wondering because someone recommended diigo in my webcraft php intro course. so now i'm signed up for both. :) [22:33] can't beat the price [22:34] is pastebin not account-based -- purely anonymous? that seems like a good feature. [22:35] yep [22:35] makes it handy for very quick things you want to post on forums etc that you don't care about saving [22:36] I have a file clickablemapicons-latest.html that I downloaded and when I cut/paste from that the nasties appear. [22:36] cool, thanks. [22:38] makes sense [22:38] @introvert Whoop! [22:39] ok, introvert, I pasted a working local openlayers map into pastebin: http://pastebin.com/aaKUza23 [22:39] (works in jsfiddle, locally, and on my website) [22:42] okay thanks [22:43] * introvert goes off to find the error [22:43] lol [22:49] i need to head off to make some dinner. goodnight folks! [22:50] ciao [22:50] Phew, local now works for me! [22:51] yay! [22:51] Whoop! [22:51] All caused because I am a beginner at html as well [22:51] goodnight everyone. [22:52] introvert: that's great ! [22:52] I have one last q- how do I get the filename for icons? [22:52] ciao [22:53] I don't know if this works in your browser... right click and you should have 'Copy Image URL' or 'Copy Image Location' [22:53] introvert: can you describe problem + solution and post it to the forums? [22:54] yes. I thought I had tried that, must have needed more tea!
