QGIS Python (PyQGIS) - Loading and symbolizing raster layers

[@IyadKhuder]

Thanks a lot. It's great. Just if I could ask you to increase the font size of the code a bit in future videos, because it's too small for some viewers I guess (at least for me) thanks anyways :)

[@dominikzaire3020]

i guess it is pretty randomly asking but do anybody know a good website to watch new movies online?

[@isaiahmarvin9492]

@Dominik Zaire try Flixzone. Just search on google for it :)

[@alivan7334]

@Dominik Zaire i use flixzone. Just google for it =)

[@leonleroy1291]

@Dominik Zaire I watch on flixzone. Just search on google for it :)

[@andrewjalen8727]

@Dominik Zaire I watch on flixzone. You can find it by googling :)

This is a great tutorial but does anyone know what the code would be to add gradient stops between the minimum and maximum values? I want to use equal intervals and have a specific number of classes.

[@okerekechisom4985]

How can I Script showing the following with PyQGIS: 1. Number of polygons that have the selected leading species. 2. Minimum and maximum area of the stands that have the leading species. 3. The average of the leading species percentages within the stands. 4. The total area and average area of the stands, containing the leading species.

Hay - I keep getting an error while opening the QGIS application. Error = utf-8 codec can't decode byte 0xfd in position 3: invalid start byte can you help?

AttributeError: 'NoneType' object has no attribute 'dataProvider' , please guide me!

[@piyaphatc5794]

omg, I just fix it by myself

[@piyaphatc5794]

I wrote the wrong file name

[@yunusemrekarpuz668]

same, thanks :)

[@bhdotyeh]

Hi - do you know how to use estimated (faster) accuracy when computing band min/max values as opposed to exact values?

[@natanaellorenzi5]

Hi dude. Thanks for this video. I have a question. Can i create a script to import csv and shp and automatically generate a layout with a pdf as output (print composer)?

[@geospatialschool]

Yes you can. I don't have a specific video on that, but this one will get you started.

How does it work to shade a raster layer using the QgsPalettedRasterRenderer class?

[@geospatialschool]

I haven't tried this yet. Here's a link to the Python documentation for the class as a place to start: qgis.org/pyqgis/3.2/core/other/QgsPalettedRasterRenderer.html I will add this to my list of videos and try to get a tutorial made in the next few weeks.

[@nicolerodriguezvargas223]

Is it possible to make a code that interpolates some points and generate isolines? Thanks!

[@razvanafloarei6256]

What have you imported at line 1: Fn='C:/temp/smr/trimmer_peak/dem/dem.tif'

[@geospatialschool]

This is the path to a raster file

[@annasam4461]

Hi, Is there anyway to create a raster attribute table using QGIS Python ?

[@crtnnn]

Page in the video description not found :(

[@geospatialschool]

I updated the description with new links

[@DanielCardin_ATX]

At 3:07, several extra lines of code appear and there's no reference in the dialog to them. Am I missing something?

[@geospatialschool]

Sorry. That's my mistake. The code gets information from the file, gets the file name without the directory path or extension, and adds a raster layer the QGIS interface with the layer name the same as the file name. As long as you add this line of code you'll be okay: rlayer=iface.addRasterLayer(fn) where fn is the path to your raster layer.

i want to use SCP, how can use it through script

[@joshdaking2324]

Mine came out grayscale 🤷‍♂️

[@kavitachaudhary2818]

dataprovider() showing error "AttributeError: 'NoneType' object has no attribute 'dataprovider'." Qgis version is 3.4.2. suggest a solution please.

[@geospatialschool]

You probably need to use 'dataProvider()' instead of 'dataprovider()'.

[@adityaeaturu2058]

Which QGIS version are you using?

[@geospatialschool]

In this video, I believe it's version 3.4. The lowest version it would be is 3.2.

[@adityaeaturu2058]

@@geospatialschool Thanks! That was quick

Hi, how can I visualise DEM with flood analysis.

[@geospatialschool]

What kind of flood analysis do you want to do?

Join tables using PyQgis! please cover

[@yassineghanou8210]

if you found the way please help me

[@lloydpal1542]

sir i have a error in this tutorial i wonder if you have the file in the .tif file base on the line 1 is not define please answer my problem thankyou

[@geospatialschool]

You can download any .tif file and use it in place of the file I use in this tutorial

[@lloydpal1542]

@@geospatialschool thanks sir

[@isaacsilva2637]

Can you make this in the new version please ?

[@geospatialschool]

This will work with any version of QGIS 3. Just tested it.

[@b.j2770]

where is the raster/file.tif file?. can i download?

[@geospatialschool]
