How to split a polygon using R-geographic information?
When using sf features, the tool st_make_grid creates polygons of equal size that covers a shapefile. Set the spacing between each grid line with cell size. Thanks for contributing an answer to Geographic Information Systems Stack Exchange!
What’s the best way to split a polygon?
When you are splitting polygons, make sure your sketch cuts completely through the selected polygon. Edge snapping often helps ensure that the cut operation is completed successfully. When working with geodatabase features, you can set up split policies that control the behavior of an object’s attributes when it is split.
How to make a polygon like a line?
To make horizontal grid like lines, first create points by combining Xmin and Xmax with all Y values Now create a loop to combine each row of vpXmin and vpXmax to get the coordinates for each line Once you have both your grids and the polygon as spatial line objects, getting the intersection points between those is easy
How to separate polygons into a data frame?
I would like to have each polygon separated as a sf (data.frame) class where each polygon object is show as a row in the data.frame I show below an example. I start by creating an example dataset:
How to separate a multipolygon geometry into several polygons?

How to divide an irregular polygon into multiple polygons?
I have an irregular polygon which is a spatial object. I want to divide it into multiple polygons (say, n=25) with equal height. To show how I want to divide it, I’ve plotted grids on the background using:
How to combine two polygons into one polygon?
I then perform a st_union () operation to combine all polygon geometries that intersect or touch (the two squares above) into one:
How to separate a polygon into a geometry?
I would like to perform an operation that separates each polygon into a geometry as shown in the figure above, but resulting in several polygon objects, something equivalent to this: How can i do this using the sf package?
