Re: [Qgis-user] how to convert a circular string into a standard linestring?

2022-06-14 Per discussione Richard Greenwood via Qgis-user
Thanks Nicolas. I'm using a memory layer. Copying the curve to a type-constrained layer did convert it to a linestring approximating a curve but the density tool gives more control. On Tue, Jun 14, 2022, 4:49 PM Nicolas Cadieux wrote: > Hi, > > Also, if your default file format is .shp, then,

Hello Richard, Try to use the densify tools from the processing toolbox. Either densify by count or densify by interval should work. https://docs.qgis.org/3.22/en/docs/user_manual/processing_algs/qgis/vectorgeometry.html#densify-by-count The tools can be used as in-place mode, so you can select

[Qgis-user] how to convert a circular string into a standard linestring?

2022-06-14 Per discussione Richard Greenwood via Qgis-user
I used the Edit menu function "add Circular String" and got just what I wanted. But how can I convert it into a regular linestring with a bunch of vertices that approximate the curve? Specifically, I need to be able to trace the curve with the Split Features tool and trace it when drawing a

Quick update. Managed to fix the annotations using an expression in layout: CASE WHEN @grid_number < 0 AND @grid_axis ='x' THEN (@grid_number /-15) WHEN @grid_number = 0 THEN @grid_number = 24 WHEN @grid_number > 0 AND @grid_axis ='x' THEN (360 - @grid_number)/15 WHEN @grid_number >

Hi Andrea, This exists for adjacent LineString geometries already, but as far as I know not for polygons. See "Rendering" section of the label settings and the option "Merge connected lines to avoid duplicate labels". It would probably be possible to add this for polygons as well if

[Qgis-user] "Merged Features" for label

2022-06-14 Per discussione Andrea Giraldi via Qgis-user
I've appreciated the "Merged Features" renderer introduced in Layer Styling since 3.22 (or maybe sooner). My question is ifanyeone can suggest a way for a similar Merged Features style for labeling: only one label for any group of adjacent polygons with the same attribute in a field, without the

[Qgis-user] Astronomical map

2022-06-14 Per discussione Lester Anderson via Qgis-user
Hello all, I am interested in how one can generate an astronomical map based on Right Ascension (RA) and Declination (Dec), without converting RA to degrees and reversing (-15 * RA). There is the affine transform tool which can be used to scale X and flip, but this then generates the 0-360
