I'm interested in creating a fishnet where the origin of the fishnet builds from the center of a polygon feature class and builds out around it rather than building the fishnet starting from the lower left corner and only only the Y-axis and X-axis as depicted below. Using, ArcGIS, arcpy, python etc... is doable.
I've tried a variety of approaches, attempting to change the origin, at least think I was able to, or adding some sort of value to "buffer" or "pad" the input extent and or xy values, to no avail. I haven't come across much that can offer me in assistance thus far.
Creating fishnet grid with specified rotation angle in ArcGIS Desktop? includes a response:
However, if you don't want to do the math or need to set your origin at a different point than the CRS origin, there's a step to take prior to starting the fishnet tool to get your y-axis coordinate.
However, I'm not sure how to implement.
I've read through:
