Question 1

I am working with several NetCDF layers with climate data in QGIS 3.34. Each layer contains the mean value of its variable for a given time series, therefore it has not several bands/time steps values....

Question 2

I have this code to download and create a mesh data for wind velocities from a weather model. However, I am having issues with the wind barbs. I have to manually activate and click on the meshvectors ...

Question 3

I am writing a Python script to process mesh data using PyQIS. I would like to specify the dataset, in groups, and change the color styling. This is easily done through the GUI interface, However, I ...

Question 4

I am struggling with the compatibility of grid meshes created in ArcMap and QGIS. When I generate a 10 km × 10 km grid within a specified bounding box (defined by latitude and longitude) in both ...

Question 5

I have a mesh data looks like below. It's in a .csv format. The top row (0, 2, 4 ...) is longitude, and the first column (0, 2, 4 ...) is latitude. They are just the numbers assigned by non-mapping ...

Question 6

I am updating a lab for a class that we ran two years ago with no problems. The lab involves adding a netCDF file from NASA's Ocean Surface Current Analysis Real-Time program. Previously, when we ...

Question 7

How could I compute the difference along the Z-axis between two terrain meshes in QGIS? I have two mesh PLY files (different sources) of the same region and I wish I could check their elevation ...

Question 8

I'm using QGIS (3.34.7) and I'm trying to get a grip on meshes. In this example, I'd like to select mesh elements within a polygon layer (and later export them). QGIS (3.22) introduced "Select ...

Question 9

I'm trying to show the difference between two meshlayers. I added the layers from Layer>Add Layer> Add Mesh Layer. The layers are extracted from a .nc-file. Right now I can see the added layers ...

Question 10

I have following data: oblique photos points representing camera location with x, y, z coordinates (EPSG:2178) and omega, phi, kappa trapezoids representing photo extent taken from given camera ...

Question 11

I was wondering if there is a Python CLI, package or even a QGIS tool that makes it possible to convert a DEM from raster to mesh. The only way I found at the moment is sampling points from the raster,...

Question 12

QGIS can read time-varying GRIB files as a "mesh" data source, which is neat. The dataset is documented to be either a scalar or vector dataset. I'm able to open my GRIB files as scalar ...

Question 13

I realized a TIN mesh from isoipse with QGIS. I would like to export it, but the problem is that I can't export the file. How can I do this?

Question 14

I am trying to create a 3D terrain map in Sketchup, based on a DEM file from the UK LIDAR series. I can add the DEM to QGIS as a raster layer and then use DEMto3D to produce a mesh in .stl format ...

Question 15

I have calculated flow direction meshes in QGIS using PCRaster tool and Crayfish plugins. The result (white lines) I get is the following (see screenshot): Is it somehow possible to extract this (...
