could you please help me solve how to batch process a large number of geometric shapes using QGIS?
The geometric shapes in the layer are offset from their correct positions, and I need to adjust them one by one. The shape does not need to be changed, but the position of the shapes needs to be changed. There are thousands of such shapes in my layer. Do you know how to quickly adjust these offset shapes to their correct positions? My layer has four fields, namely id, geome, xqid, update_date. update_date is the time when null becomes saved every time the graphic is manually moved to the correct position and saved.enter image description here

I created a temporary polygon layer with a column called “class”. This layer is empty, and I want to start adding features in. But I want to limit my class values to be either A, B, or C (enum type).

I would like to calculate the length of the front of a house (a layer of houses) in QGIS. I know how to manually measure each house but i am looking for a way to measure it for all houses in the layer.

I’m trying to automate a simple process multiplying two rasters, both contain only 1 and 0, to get 1 where both have the value 1.
When I use the raster calculator with the same input manually, it runs smoothly, yet every time I use it in the model builder I get “Error creating output file.”

When processing in QGIS, this green X appeared at the coordinates 0º latitude and 0º longitude. What does this mean? And how can I remove it?

I am not a map expert what so ever and need help fixing the grid numbers on a this Antarctic map.
**The grids should be displaying a longitude that covers where my data points (sites) are sitting: Longitude of ~166°26’17″E-166°27’11″E and latitude of ~77°12’44″S-77°13’04″S. Instead the grid has listed coordinates with a latitude of 30°0’0.000″S-50°0’0.000″N and a longitude of 0°0’0.000″S-100°0’0.000″E. **
