I'm a beginner QGIS user and am struggling with creating a grid. I've used the MMQGIS geometry import function to import data from the CSV file shown below but they pop up as points on QGIS. I want to make it into a grid so that I can pretty much have each of the points be in a box format. I've also tried to use the join function but am not sure what variable both the grid and the points have so that I can join them.
In QGIS3 you can create a layer from a delimited text file using [Layer] > [Data Source Manager] > [Delimited Text] which allows you to select the delimiter (CVS is one of the options) and to select 2 of the fields (columns) to be used as the X and Y position of the point. The other fields are stored in the Attribute Table.
To create some sort of polygon grid from those points, you can:
- first, use the
Points to Pathalgorithm (you can find in Processing); in the
Order fieldbe sure to use an attribute which is unique for each of the four corners (maybe
DEGSQfrom your screenshot).
- Use the
Lines to polygonalgorithm to obtain the desired polygons.
You can see each of the three geometry phases below:
