[QGIS-ZA-user] Curved Road Labeling Issue

QGIS-za-user mailing list
Hello,

I am hoping someone can assist me. I work on a game reserve and am currently making a new map of all roads. I have captured (ground-truthed) all roads and now am working on the aesthetics part (symbolization & labeling). I am currently working on QGIS Version: 3.6.0 (Noosa).

I feel like I have tried everything to get the labels to follow the curves of the roads at 1:20 000 but I am just not winning. I have watched & read what feels like many hours of videos and tutorials online but still no success. 

In the "Labels" section of the Road layer properties window I have tried selecting the "Curved" option under "Placement" but once selected all road names seem to disappear. I then tried different variations of the "Allowed positions" options but still no luck. I also tried adjusting the "Maximum angle between curved characters" but that didn't seem to make a difference, at higher numbers one or two letters of words appeared. 

For the above explanation I had been using "Single labels". Should I rather be trying this using "Rule-based labeling"? 

Below is a screenshot of a portion of the road network I am dealing with. The end goal is to get the map printed out (at about 1:20 000) on A0 or larger size.

Any help on this would be hugely appreciated!

Kind regards,
Catherine

Hi Catherine

Are you sure you haven’t made labels scale dependent and they’re disabled at that scale?

You should be able to do it fine with the ’single label’ option. Those options don’t affect placement.

If you’re prepared to share some or all of your data with me or the list that would help.

Hi Catherine

I’ve attached a little QGIS project with an example of using curved labels.

Hi,
I have never had an issue and always plot "curved" although I notice your roads are very squiggly and that may be the reason?  Try smoothing one just for an experiment

Re: Curved Road Labeling Issue

My experience is that even with show all labels activated I still drop labels with the curved options...but my opinion doesn't count as I am STILL using 2.18 (!)

Re: Curved Road Labeling Issue

hey guys

I have this topic for my project at school. "One of the trending toics in GIS is the creation of geoapps. Create a geoapp for all the modern restaurants in the Durban City". My question is, which GIS software is best for this assignent? Thanks!

Re: Curved Road Labeling Issue

QGIS-za-user mailing list
Hi

Have a look at ODK [1] or Epicollect5 [2] - they will let you gather data on your phone and then download it and show it on a map in QGIS. Creating an app yourself is probably a bit ambitious unless you have been deep diving into software development at school.


Have fun!

Regards

Tim

Re: Curved Road Labeling Issue

QGIS-za-user mailing list
In reply to this post by QGIS-za-user mailing list
As Tim suggested using ODK is an easy and accomplishable way of doing this...I’ve used it a lot and suggest using an organization called  ONA  to manage ODK, there is a free tier and really intuitive 

Cheers

hey guys

I have this topic for my project at school. "One of the trending toics in GIS is the creation of geoapps. Create a geoapp for all the modern restaurants in the Durban City". My question is, which GIS software is best for this assignent? Thanks!

Hi,
I have never had an issue and always plot "curved" although I notice your roads are very squiggly and that may be the reason?  Try smoothing one just for an experiment

Hi Catherine

Are you sure you haven’t made labels scale dependent and they’re disabled at that scale?

You should be able to do it fine with the ’single label’ option. Those options don’t affect placement.

If you’re prepared to share some or all of your data with me or the list that would help.

Re: Curved Road Labeling Issue

Catherine sent me some sample data and this was my response to her - it was just a matter of working in a projected CRS (as one should always do for cartography)

-------------------------------

’it just works’

QGIS 3.6

all I did was to select ‘curved’

note when you make maps you must use a projected CRS - in this case LO31 (‘HBKNO31’ in QGIS). Just maybe you were in 4326 and using units that don’t make sense with unprojected geometry?

I feel like I have tried everything to get the labels to follow the curves of the roads at 1:20 000 but I am just not winning. I have watched & read what feels like many hours of videos and tutorials online but still no success.

In the "Labels" section of the Road layer properties window I have tried selecting the "Curved" option under "Placement" but once selected all road names seem to disappear. I then tried different variations of the "Allowed positions" options but still no luck. I also tried adjusting the "Maximum angle between curved characters" but that didn't seem to make a difference, at higher numbers one or two letters of words appeared.

For the above explanation I had been using "Single labels". Should I rather be trying this using "Rule-based labeling"?

Below is a screenshot of a portion of the road network I am dealing with. The end goal is to get the map printed out (at about 1:20 000) on A0 or larger size.

Any help on this would be hugely appreciated!

Kind regards,
Catherine
