| 07:12:42 | WidgetAlley: | Hullo again all, quick newb question: I've added a delimited text layer with coordinates of points, and it seems to work fine, but when I go to the symbology tab and select an icon to represent the individual points, nothing is displayed. What's up? I have a feeling I'm missing something obvious. |
| 07:14:51 | FiReSTaRT: | you mean unique values symbology? |
| 07:16:22 | WidgetAlley: | Actually I was using single symbol, since all the points are the same. Do I need to be using unique value? |
| 07:17:05 | WidgetAlley: | The points are all the same TYPE of location, I mean, rather than the same geographic location. ( Mapping the location of legal non-profits across counties, just want little stars to represent them... ) |
| 07:17:19 | FiReSTaRT: | ahhh ok |
| 07:17:24 | FiReSTaRT: | that should be simple |
| 07:18:07 | FiReSTaRT: | open the symbology and if the legend type is single symbol, you can just select a different symbol.. make sure that the size and the fill colour are distinguishable against other layers |
| 07:18:53 | WidgetAlley: | Okay, let me try it... |
| 07:20:10 | FiReSTaRT: | ok.. ill be here for another 5, taking a quick 15min break, and then be back for a while : ) |
| 07:20:14 | WidgetAlley: | The symbols still don't show up. I even scaled them up to a ridiculously huge size, thinking I was missing them, and they're simply not there. The layer box in the legend is checked, so the csv layer should be displaying... |
| 07:20:21 | WidgetAlley: | That's cool mate, I appreciate the help. |
| 07:21:10 | FiReSTaRT: | what about colours? |
| 07:21:31 | WidgetAlley: | Changed 'em a couple of times. |
| 07:21:34 | FiReSTaRT: | and were they showing up before? |
| 07:21:38 | FiReSTaRT: | try zoom to layer |
| 07:21:57 | WidgetAlley: | No, not even when I first load the layer did they show up. |
| 07:22:00 | WidgetAlley: | loaded^ |
| 07:22:35 | WidgetAlley: | Okay.... weird... I zoomed to the layer and they show up now. Hunh. |
| 07:23:04 | FiReSTaRT: | not really... but you may be having some projection issues... make sure you use the ftools to define the projection : ) |
| 07:23:09 | FiReSTaRT: | ooops |
| 07:23:16 | FiReSTaRT: | u can define the projection from the regular menu |
| 07:23:19 | FiReSTaRT: | and ftools to reproject |
| 07:23:34 | WidgetAlley: | Cool. |
| 07:23:42 | WidgetAlley: | Thanks! |
| 07:23:50 | WidgetAlley: | I would not have thought of that. Glad I have fTools installed. |
| 07:24:54 | FiReSTaRT: | yes.. but they are only to be used to project into a different crs.. if you define a correct crs for the layer, it should be visible against your other layers without using them |
| 07:25:18 | FiReSTaRT: | but yeah, vector work would be a real bitch without'em.... Carson rocks lol |
| 07:25:48 | WidgetAlley: | Yes indeed. Hrm. I wrote the CRS myself, it's very simple, just location, lat and long. |
| 07:26:27 | FiReSTaRT: | ahh ok unprojected |
| 07:26:52 | WidgetAlley: | I have the "CRS on the fly" transformation enabled, would that make a difference? |
| 07:27:05 | FiReSTaRT: | so if you want to project the data to have a matching crs for the whole project ( highly recommended not only for the whole project but also for the whole organisation if possible ) |
| 07:27:08 | FiReSTaRT: | use the ftools |
| 07:27:31 | WidgetAlley: | Sweet. Thank you very much! |
| 07:28:38 | WidgetAlley: | And for the projection, what would you suggest for extremely simple non-topographical work? |
| 07:28:47 | FiReSTaRT: | no worries.. as for the on the fly transformation, yes it works : ) |
| 07:29:06 | FiReSTaRT: | well it depends on the region you're covering.. is it global or localized? |
| 07:29:41 | FiReSTaRT: | if it's global, i'd even consider leaving it unprojected for now and then decide whether you want to preserve shapes, areas, distances etc etc etc |
| 07:29:56 | WidgetAlley: | Fairly localized... the largest area I will be using is one state, and most of it is by-county work. |
| 07:30:50 | WidgetAlley: | Heh, I think I would be getting a little ahead of myself to try global at this point. ( Maybe someday! ) |
| 07:31:15 | FiReSTaRT: | lol |
| 07:32:12 | FiReSTaRT: | as long as the state is in the same utm zone, your best bet would probably be utm nad83... distortion is minimised : ) |
| 07:32:26 | FiReSTaRT: | very easy to work with |
| 07:33:15 | WidgetAlley: | Sounds good to me. |
| 07:33:23 | WidgetAlley: | Thank you very much, once again! |
| 07:33:28 | FiReSTaRT: | no worries : ) |
| 07:33:50 | FiReSTaRT: | oh another one you can use is state plane ( if you're in the states ) |
| 07:34:24 | WidgetAlley: | Cool. I will see which one catches my fancy. |
| 07:35:02 | FiReSTaRT: | to me state plane is haphazard and too localized... utm is more systematic and applies to the whole world |
| 07:36:44 | WidgetAlley: | Awesome. That sounds better, so that if someone takes over and expands the project after me, they won't have to tweak it again. |
| 07:38:19 | FiReSTaRT: | not much tweaking required but yeah, might as well keep it systematic : ) |
| 07:38:32 | FiReSTaRT: | living in the global village and all :P |
| 07:38:53 | WidgetAlley: | Hm. |
| 07:38:56 | WidgetAlley: | It's giving me a Python error. |
| 07:39:05 | FiReSTaRT: | what's giving you a python error? |
| 07:39:19 | WidgetAlley: | Trying to define the projection for the CSV layer through FTools. |
| 07:39:45 | WidgetAlley: | Turns out all the other layers have NAD83 enabled, so I'm trying to import the spatial reference system from those layers. |
| 07:40:29 | WidgetAlley: | And it gives me an "no such file or directory" error. |
| 07:42:55 | FiReSTaRT: | it depends.. if there is no .prj file associated with them, even if you know the data is in utm nad83, it could still be "undefined" as far as qgis is concerned |
| 07:43:41 | WidgetAlley: | There's a .prj for all of the shapefiles. |
| 07:43:51 | FiReSTaRT: | weird |
| 07:44:05 | FiReSTaRT: | define it manually then |
| 07:44:07 | WidgetAlley: | Yup. But I'll just select 'em manually, no worries. |
| 07:44:13 | WidgetAlley: | Lol. |
| 07:44:49 | FiReSTaRT: | ok i better run now... bbin15 or so : ) |
| 07:46:02 | WidgetAlley: | No worries! :D |
| 08:01:10 | FiReSTaRT: | back : ) |
| 08:03:36 | FiReSTaRT: | ok looks like you're chugging away happily, so i'll go and play some trade wars :P |
| 08:04:54 | WidgetAlley: | Actually, I'm still trying to figure it out. ( But Trade Wars is awesome! ) |
| 08:05:32 | WidgetAlley: | I've opened a new project so it's clean, uploaded my shapefile and CRS, made absolutely sure through FTools they're in the same projection, and I can still see one or the other but not both. |
| 08:06:17 | WidgetAlley: | ( They're in WGS84 for the purposes of the experiment. ) |
| 08:12:43 | WidgetAlley: | .... |
| 08:12:44 | WidgetAlley: | Oh my God. |
| 08:12:50 | WidgetAlley: | We're going to pretend that this didn't happen. |
| 08:13:16 | WidgetAlley: | Somehow QGIS switched my lat/long coordinates when it imported the CSV file. No wonder it wasn't showing up. |
| 08:13:53 | WidgetAlley: | Oh, God, these conversations are logged, aren't they? LOL. Well, I've learned a lot and thank you very much for all the help. When something REALLY goes wrong now I'll know how to handle it. |
| 08:14:18 | WidgetAlley: | *shuffles off looking mildly ashamed* |
| 08:36:19 | rtb: | WidgetAlley: Thank you. Now I won't be so reluctant to ask my own "dumb questions" in the future. ; ) |
| 08:41:09 | WidgetAlley: | I didn't think it was.... oh well. Live and learn. |
| 08:52:12 | WidgetAlley: | Thank you again! I'm sure I'll be back with more dumb questions.... :D |
