Re: [Qgis-user] Small towns and villages of France

[Frank Broniewski]

Hi Hamish,

I don't think NE has the appropriate scale for villages, it is far too 
small. Your best bet is probably using data from Openstreetmap. Get 
yourself a recent copy from here [1], look at the point layer and the 
attribute you want is "place" = 'village' or "place" = 'hamlet' [2].

Just for completeness of the discussion - 
You can use org2ogr to separate and save the layers. As Rick notes
above, you can get all the underlying data from the National Map.
Pulling out the layers with ogr2ogr will give you layers with the
same extent as the quad you're interested in if that matters for
some reason.

Re: [Qgis-user] [EXTERNAL] Re: 2019 USGS 7.5min topo sheets

[Fielding, Eric J (US 329A)]

I was able to open a USGS GeoPDF for a 2018 map of Pasadena, Calif. with Adobe 
Acrobat (and Acrobat Reader) and it loaded quickly. The file is a vector file 
with all the line work stored as vectors. I was also able to open it in Adobe 
Illustrator, but that was slower. Illustrator sees the GeoPDF with only one 
layer, but has a huge number of vector lines for all the contours. I don’t see 
a raster layer in Illustrator. QGIS 3.10.3 on my Mac was not able to open the 
GeoPDF as either a Raster or Vector database.

I also noticed that opening the folder with the GeoPDF in Adobe Bridge caused 
the Bridge program to allocate 19 GB of memory, which is not very helpful on a 
laptop with 16 GB of RAM. I had to quit Bridge to get the memory back. This is 
probably similar to what people noticed with keeping the GeoPDF on the Windows 
Desktop.

From the “Font not available” warnings in Illustrator, I see the GeoPDF must be 
created with an ESRI program as some of the fonts had ESRI in the name. I 
assume that ESRI ArcGIS can open the GeoPDF.

I am running Qgis 3.4.2 on Windows and I can load the new style geopdf USGS 
7.5' quads, including the imagery layer.
It's slow and grinds qgis to a halt while it loads, but it does work. The 
different layers, which are independently controllable in Acrobat Reader are 
flattened when the topo is opened in Qgis, which rasterizes the image and 
presents it as one raster, not separate layers.
USGS has made these maps much less useful by adding the aerial imagery layer, 
at least for me. Qgis isn't the only application that flattens the layers, and 
the imagery obscures way to much for my taste.

[Qgis-user] Accessing qGIS APT repositories using Tor

[patagioenas]

Greetings,We would like to get in touch with the website operator of qgis.org 
in order to discuss an issue regarding the access of the apt-get repositories 
using Tor (https://www.torproject.org/).Long story short: the current CloudFare 
configuration of qgis.org is preventing Tor users from installing qGIS using 
the debian (APT) repositories.Could you please put us in touch with the website 
operator? alternatively we can detail the different workarounds here.Thanks :-)___

Re: [Qgis-user] [QGIS-User] QField: adding photos, but how?

[Marco Bernasocchi]

Hi Bernd,

yes that is indeed the correct documentation, I updated all the images
since there ad been an error in publishing.

We currently have an build error in the doc, wich we're fixing.
Meanwhile you can see the updated text [0] and screenshots [2] on
github. Or have a look at the original issue which has documentation as
well.

can you check if all works well now?

cheers

Marco

[Qgis-user] LOSS OF DATA AFTER DELETING DUPLICATE GEOMETRIES

[Bernard]

Hi,
I used MMQGIS to delete duplicate geometries. After deleting, I saved the file 
using a pre-existing name, overwrote the file and opened it.
The file was blank. What could have gone wrong? I have lost all the 
data/records in the old file. The attribute table was blank and the file fise 
1kb.
How do I recover my records?

[Christine]

Dear Nicolas,
thank you for clearing. 
Then the download file itself is most pobably the reason for the problems.  

Reagards, Christine

Nicolas Cadieux:
... The PC desktop. If you download the last version of adobe reader, you
should be good. The download folder should be good. Having a PDF on the PC
desktop would send the PC cpu at 100% usage.
