[Qgis-user] symbology shapefile polygons: equal intervals classes
Dear all, I have a shapefile of polygons and I would like to classify it (in symbology) using for example 6 classes with these values 0-10 10-20 20-30 etc. The field to classify has values from 0 to 63.4 (decimal numbers). And I would like to have the result in graduated colors. Till now I have been using: *Symbology*/graduated *Method* color and I give a color ramp *Mode: *equal interval and I give the number of classes, the problem is that I must insert the classes manually (one by one) otherwise the numbers are not entire. Please can you suggest me any other faster method? (for example for the raster I can give minimum and maximum as integer number -in this case it would be 0 - 60- and I can specify the number of classes and automatically Qgis tematize the raster with equal intervals (all the classes and not one by one).

Re: [Qgis-user] SPLIT POLYGONS INTO 3 PARTS (similar size)
Hi List, I ask you again the same question I asked you days ago. I have several polygons - around 200- (all different shapes and not regular geometry) and I need to split every single polygon into 3 parts of similar size. I have tried with *Split polygons* but it is working very well only with regular geometries (square, rectangle etc.) and so I can not use it in this case. I have tried also your suggestions (generate points, kclustering and voronoi polygons):https://gis.stackexchange.com/questions/321021/how-to- split-polygon-into-equal-area-polygons-in-qgis-3 and https://blog.cleverelephant.ca/2018/06/polygon-splitting.html but I am not able to do it to all 200 polygons at once..

[Qgis-user] How to create / copy and paste annotations
Hi to all, I must draw some annotations in my project qgz (in the canvas): letter + number and a frame around. I did this with "text annotations", but it is not so comfortable because I must make several changes to create the label (and even after this I can't obtain the label I would like) and I don't find the way to copy and paste these annotations (in order to avoid to repeat the modifications for every label). Is it in Qgis another way to make annotations and to copy and paste?

[Qgis-user] raster: calculate area
Hi List, I have a raster file DTM (altitude attribute in the pixels). I reclassified this raster in 4 classes of altitude and I need to calculate for each class the area (in how many square meters is each different class extended). I can for example transform the raster file reclassified into a vector file and calculate the area, but is it possible to do without any vectorialization and so directly calculating it from the raster file?

[Qgis-user] move 4 concentric circles from a position to another with a specified center
Hi to all, I must draw four different concentric circles (with different sizes and same center) in many different positions: about these positions I know the center of the circles (shape file of points). I created a shapefile of polygons for these circles but I would like to find a method to copy the 4 concentric circles and paste the same 4 circles in different positions (of which I know the center). Do you know any method? for example a kind of snap to the point. If I do it manually it is almost impossible to put the circles exactly in those centers.

[Qgis-user] change pixel value from no data to zero
Hi to all, I am using qgis 3.16. I have a raster file that I created from shapefile of polygons (rasterize of GDAL) using a column that has the number 9 every where there are the polygons. This raster has 2 different values in the pixel: not data and 9. I need to have 0 (zero) instead of no data. What can I do? Can I change the pixel value from no data to zero? Before when I used the version 2.18 I could create directly with rasterize a file with these two values.

[Qgis-user] UNION OF FILE VECTORS (different geometry) and rasterize
Hi to all, my aim is to obtain 1 raster file (an image) from 2 different vector files (esri shape) that are of different geometry : one is polygon geometry and the other is line geometry (in the same area). For example I have some buildings and streets (in two different vectors with different geometry) and I would like to obtain a single raster file (an image with buildings and street). Is it possible and how? - normally if I need to rasterize a single shape file I use saga rasterize, but in this case I don't know how to do because I have 2 different shapes and with different geometry and also I dont know how to do the union or merge of shapefiles with different geometry (maybe creating a geopackage??). Every kind of suggestion is very welcome.

[Qgis-user] georeferencing raster GDAL - PLUGIN
Hi to all, just an observation regarding the plugin georeferencing. A premise: since years I am using Qgis instead arcgis and I am really happy of this software and I think your project is great, congratulations and many many thanks!! However the only operation I am still doing in arcgis instead of qgis is the georeferencing of raster maps (I never tried the georeferencing of vector), so I would like to understand if there is another plugin or another way of georeferencing of raster maps using qgis (I am using GEOREFERENCING raster GDAL). The problem is for example that in qgis during the georeferencing I can not see the 2 two maps together and this make the georeferencing very long and difficult, on the contrary in arcgis I see the maps together and georeferencing is faster and easy. So I would like to understand if I am not using properly the command or if there is another solution. Thank you.

[Qgis-user] problems with raster (merge, clip) and crash dumped
Hi to all, I am using for my Bachelor classes in university qgis 2.18 but some of my students have the problems below. They even format the computer completely and the reinstall windows 10 + the softwarer qgis (they even tried different versions of Qgis 2.18) but they still have these problems (I never had these problems in my computers with the same versions of Qgis and with other versions). In the new version of QGIS is better but still (in the same computers) as well as is in my computer with the same versions (for example the merge is not perfect because the file are still separated! so I dont think is a problem of which version they use. ERRORS: When they upload files RASTER with extension .asc they have the yellow message: Python error: an error has occurred while executing Python code They can see well the file .asc in the project but they can not do MERGE and CLIP. MERGE Normally they try to do the Merge of different ASC files with Raster/Miscellaneous/Merge and the error message is: error 4C... no such file Normally they try to do the clip of raster files .TIFF from Raster/Extraction/CLIPPER and the error message is: "ascii" codec cant encode character u'/xe0' in position 60: ordinal not in range (128) ... So I don't understand what can I do, because they have also formatted and cleaned the computers and in my computer and in some other computers everything is fine with the same versions and commands. Another problem that is also in some other computers is that when they exit from the project, they have this error message (that close the project without saving): CRASH DUMPED : minidump written to C ...

So, assuming you have e.g a point layer in EPSG 32632 (metric) and want the coordinates calculated in the field calculator, but the result should be in EPSG 4326 (degree), you can do: for a new X column |X( transform( $geometry, 'EPSG:32632', 'EPSG:4326')) | and similar for a new Y column |Y( transform( $geometry, 'EPSG:32632', 'EPSG:4326')) | |in the field calculator.| || Answer found here: https://gis.stackexchange.com/a/242259/8202 Cheers, Bernd Am 19.03.19 um 18:43 schrieb Azzurra Lentini: Good morning, if for example my project is in this referencing system: WGS84-UTM, when I ask to calculate the coordinates Y and X (with field calculator - geometry), it will produce the coordinates in meters.

[Qgis-user] Fwd: different buffer distance for each side
Thanks Nyall. I dont know why but GDAL SINGLE SIDED BUFFER it doesnt work really well. The result of this buffer is a line and not a polygone (the line is the same of the input file!!) I just put my input file and 150 m for the distance buffer for the left side.

[Qgis-user] different buffer for the same field
Dear all, I have a shape file with a field called “type”. In the “type” field I have 4 kinds of samples ( 19 records). See in the attachment. The 4 samples are: normal fault, inverse fault, overthrust, syncline. I would like to create a buffer with different distance for each sample (the best it would be to obtain a shape with 5 different buffer distances). For example the buffer distance for the sample “ normal fault” is 30 m, for the “inverse fault “ is 20 m, for the “overthrust” is 50 m and for the “syncline” is 20 m. How I can do this kind of buffer??
