Update on GeoPDFs in QGIS.

So almost a year ago to the month I wrote about the somewhat convoluted process on generating a GeoPDF in QGIS. In short:

  • Made a change in map composer to make a georeferenced tif
  • Defined the projection of the tif
  • Converted the tif to a pdf

Today I discovered in 2.18.1 – it works. You just export a PDF. I was preparing the execute the process that started the blog article from a year ago and stumbled upon “hey it works now”. So I can toss all that other stuff out and just go back to exporting a pdf.

I dumped on out and checked it with gdalinfo test.pdf 

Driver: PDF/Geospatial PDF
Files: test.pdf
Size is 1650, 1275
Coordinate System is:
PROJCS[“NAD83 / Tennessee (ftUS)”,

Granted it’s not a TerraGo Geopdf (with all the coolness that happens there) but it does work and can be loaded into various PDF viewing applications.

I know this is a bit late as 2.18.1 has been out for a bit. I’ve actually been a bit busier than normal and hadn’t talked about all the goodies built into Las Palmas. Don’t take that as “Well he’s unimpressed” – actually it’s been really nice and easy to work with.

A few weeks ago I found a job is restarting I had worked on a few years ago. I get to experience round 2 and it was on that initial job I had made the reluctant jump to QGIS – and I think that version was 1.7.3. I remember going “It works…mostly” and here I sit almost 3 or 4 years later and it’s all I’m using. It started me down the road to a QGIS class and other stuff that has happened with myself and work. Anyway – enough nostalgia for today. Export a PDF and enjoy the geo portion of it.

QGIS 2.18 is out

lp218

QGIS 2.18 is out and about. What’s exciting about this one? First off learn a little bit of Geography with the release name of Las Palmas.

Second – it’s the last (**I think**) of the 2 releases before 3 comes out. This one will probably be with us a bit longer than normal as the developers work on pushing QGIS into python 3 and QT5. That’s pretty exciting in and of itself.

What does the new release bring? 

  • Color picker is now embedded in layer style panel
  • Substitution list support for labeling
  • Improved line label placement algorithm
  • Label polygons using curved labels along perimeter
  • Preview of raster tiles (WMTS and XYZ layers) (yes – faster rendering for these tiles)
  • Point on surface algorithm added
  • and a whole lot more – check the changelog link above for all the news.

If you’re on 2.16 I would upgrade to 2.18. If you are on 2.14, the Long Term Release, I would encourage to load one copy of 2.18 just for general testing and playing around. There is (IMO) a lot of different between 2.14 and 2.18 – enough you should start to familiarize yourself with it. I’ve got clients on 2.14 and my official stance is stick with the LTR – but it wouldn’t hurt to take a look at 2.18.
