[17:53:11]<svenn>mstenta: go ahead.
[17:53:41]<mstenta>svenn: cool! how would you like it to appear?
[17:54:00]<svenn>appear?
[17:54:18]<mstenta>what is your full name?
[17:54:46]<svenn>Oh, Svenn Bjerkem
[17:54:52]<mstenta>great! i'll add it
[17:54:54]<mstenta>:-)
[17:54:55]<svenn>or, rather Svenn Are Bjerkem
[17:55:00]<mstenta>ok
[17:56:47]<svenn>Remember we talked about alternative background map through wms earlier this year?
[17:56:58]<mstenta>yes
[17:57:26]<svenn>I have found out how to add our local wms into qgis. Would that link help you?
[17:58:09]<svenn>I mean, you showed me a lot of settings menus for openlayers, but I am old and not good at remembering
[17:58:18]<mstenta>svenn: added - http://farmos.org/community/supporters/
[17:58:31]<svenn>ACTION reloading page
[17:58:34]<mstenta>svenn: one sec... brb
[18:02:20]<mstenta>svenn: yes that link would help!
[18:02:31]<mstenta>i can probably get the necessary URL information for the WMS from that
[18:02:39]<mstenta>brb again...
[18:05:14]<svenn>qgis is soooo slow at starting up
[18:16:42]<mstenta>back
[18:18:57]<svenn>The link I use in "add wm(t)s layer" in qgis is http://opencache.statkart.no/gatekeeper/gk/gk.open_wmts
[18:19:10]<svenn>but that is just a top level url
[18:19:22]<svenn>I can't use it directly from chrome
[18:19:54]<svenn>qgis fetches some data magically behind the scene
[18:20:21]<svenn>I must admit that I haven't done much homework on openlayers on that link yet
[18:21:53]<mstenta>actually, this URL might be what we need
[18:22:07]<mstenta>i need to refresh on how wms works in Openlayers
[18:22:21]<mstenta>but i think it "magically" appends some GET parameters to the URL to get specific tiles basically
[18:22:35]<mstenta>i will try something...
[18:23:45]<svenn>problem is that most of the documentation I find is in norwegian, so it is hard to just give you links
[18:23:48]<mstenta>it looks like this might actually be "WMTS" (web map tile service) - not WMS
[18:23:49]<mstenta>https://en.wikipedia.org/wiki/Web_Map_Tile_Service
[18:24:05]<mstenta>feel free to send links - i may be able to use google translate
[18:24:09]<svenn>it is wmts, yes
[18:24:21]<mstenta>maybe wmts works the same as wms... i'm not sure
[18:24:24]<mstenta>i'll try it
[18:24:50]<svenn>qgis didn't make a difference
[18:24:53]<svenn>http://kartverket.no/data/API-og-WMS/
[18:25:06]<mstenta>ok that's promising
[18:25:19]<mstenta>they might behave the same... but just have different features for the people hosting it
[18:25:26]<mstenta>it sounds like wmts is faster
[18:25:31]<svenn>http://opencache.statkart.no/gatekeeper/gk/gk.open_wmts?Version=1.0.0&se...
[18:25:50]<svenn>I get nothing in my browser, but that should tell the client what to expect
[18:27:12]<svenn>I use a layer called "matrikkel_bakgrunn"
[18:28:29]<svenn>and the layer source in qgis is
[18:28:33]<svenn>contextualWMSLegend=0&crs=EPSG:25833&dpiMode=7&featureCount=10&format=image/jpeg&layers=matrikkel_bakgrunn&styles=default&tileMatrixSet=EPSG:25833&url=http://opencache.statkart.no/gatekeeper/gk/gk.open_wmts
[18:28:55]<svenn>for whatever it is worth
[18:30:06]<mstenta>yea ok - i just found that too (matrikkel_bakgrunn)
[18:30:14]<mstenta>i'm building a new source in openlayers
[18:30:51]<mstenta>(what does matrikkel_bakgrunn translate to in english?)
[18:31:29]<svenn>it is the legal stuff borders, ownership, buildings
[18:31:56]<mstenta>ok
[18:32:06]<mstenta>so it is not satellite imagery?
[18:32:13]<mstenta>is there satellite imagery in this WMTS?
[18:32:38]<svenn>I have been looking for that, but I think they are behind passwords
[18:34:54]<mstenta>can you give me an area shape that i can test with?
[18:35:18]<mstenta>from the "Data" field that you see below the map when you edit an area in farmOS
[18:35:32]<mstenta>i just need it so that i can more easily zoom the map to a place for testing
[18:35:53]<svenn>ok, wait a sec.
[18:36:18]<svenn>I just dump another link I found, to something that may be aerial photos
[18:36:28]<svenn>http://gatekeeper1.geonorge.no/BaatGatekeeper/gk/gk.nib_utm32_wmts_v2?
[18:40:04]<svenn>how much of the polygon do you want? I don't want to be kicked for posting too much data at once :)
[18:41:18]<mstenta>can you draw a simple one? or just a point? you could start creating a new area, and draw a point, then copy and paste the data, but don't save the area
[18:42:11]<svenn>good idea
[18:45:16]<mstenta>in the first wmts link you gave me, i see that there are a number of different layers available
[18:45:19]<mstenta>matrikkel_bakgrunn is the first
[18:45:21]<mstenta>there are also:
[18:45:25]<mstenta>topo2
[18:45:38]<mstenta>topo2graatone
[18:45:42]<mstenta>Europakart
[18:45:47]<mstenta>topo2_direkte
[18:45:51]<mstenta>sjo_hovedkart2
[18:45:56]<mstenta>kartdata2
[18:46:01]<mstenta>ERM
[18:46:05]<mstenta>Arcticerm
[18:46:09]<mstenta>norges_grunnkart
[18:46:14]<mstenta>toporaster2_rik
[18:46:19]<mstenta>norges_grunnkart_graatone
[18:46:23]<mstenta>arcticsdi_wmts
[18:46:29]<mstenta>erreng_norgeskart
[18:46:47]<mstenta>there are a lot more it looks like...
[18:46:54]<mstenta>i don't know what any of them mean
[18:47:00]<svenn>POLYGON((11.6434907913208 63.97958079140267,11.643919944763184 63.979637271127274,11.644123792648317 63.979453711605316,11.643721461296082 63.97934545798921,11.6434907913208 63.97958079140267))
[18:47:16]<mstenta>thanks
[18:48:04]<svenn>I am not very familiar with those layers, the ones I looked at had bad resolution
[18:49:07]<mstenta>hmmm...
[18:49:08]<mstenta>so...
[18:49:14]<mstenta>in openlayers i created a new source
[18:49:30]<mstenta>url: http://opencache.statkart.no/gatekeeper/gk/gk.open_wmts
[18:49:35]<mstenta>layer: matrikkel_bakgrunn
[18:49:39]<mstenta>version: 1.0.0
[18:49:49]<mstenta>(those are the only three settings i have available in the openlayers UI)
[18:50:19]<mstenta>and when i go to the map, i see the polygon you gave me, and it looks like it is trying to make requests to the WMTS, but it is giving 501 errors
[18:50:25]<mstenta>here is one of the URLs it generated:
[18:50:29]<mstenta>http://opencache.statkart.no/gatekeeper/gk/gk.open_wmts?SERVICE=WMS&VERS...
[18:51:05]<svenn>same here
[18:51:10]<mstenta>the response says "The server does not support the functionality needed to fulfill this request."
[18:51:18]<mstenta>i'm not sure what part of that is not working
[18:54:23]<mstenta>hmm... it looks like it does not have the GetMap operation, which the openlayers module looks for
[18:54:47]<mstenta>for comparison, here is the WMS service for the NRCS Soil Survey here in the United States: http://sdmdataaccess.nrcs.usda.gov/Spatial/SDM.wms
[18:54:54]<mstenta>and here is the getcapabilities:
[18:55:07]<mstenta>http://sdmdataaccess.nrcs.usda.gov/Spatial/SDM.wms?Version=1.1.1&request...
[18:55:28]<mstenta>notice how the URL that openlayers generated above has REQUEST=GetMap
[18:55:48]<mstenta>and if you search for "GetMap" it appears in the SDM.wms
[18:55:54]<mstenta>but not in the gk.open_wmts
[18:55:58]<svenn>funny, somebody has used openlayers with the norwegian server:
[18:56:13]<svenn>https://github.com/GeoForum/veiledning08
[18:56:26]<svenn>census connected to map
[18:57:25]<mstenta>oh cool!
[18:57:31]<mstenta>and it uses the same wmts url!
[18:57:56]<mstenta>hmm... but it uses ol.source.WMTS
[18:57:56]<svenn>finally something in english: https://github.com/kartverket/example-clients
[18:58:02]<mstenta>not ol.source.WMS
[18:58:21]<mstenta>so it looks like it needs to be WMTS configured in openlayers
[18:58:42]<svenn>that census link say that they use openlayers3
[18:58:43]<mstenta>oh wonderful!
[18:58:54]<mstenta>ah! i need to go... time for dinner
[18:59:02]<mstenta>this is good though... lots of information
[18:59:07]<mstenta>i will take a closer look later
[18:59:33]<svenn>for openlayers2 it is wms-c from the clients example
[18:59:47]<svenn>suits me it is 01 am here
