I would like to convert a raster (representing a study area) to a polygon layer with features representing individual raster cells.
The raster layer contains roughly 30 million cells @150x150m.
I have tried using the Create Fishnet tool, but I want the cells to match the study boundary, not the study area boundaries EXTENT (i.e. many more unnecessary grid cells), and selecting the grid cells from the fishnet that intersect with the boundary area does not work (freezes) because of the large number of grid cells (~30 million).
Could anyone recommend a procedure for converting the raster to vector grid cells?
