I really have little or no aptitude for programming. I've created a model in model builder using fishnet (let's say 1 m cell width and height, 30 columns and 40 rows).
My problem is that I need to have 25x25 metre blocks numbered from 1 to 25 (see attachment).
The code I've managed to create just numbers them all 1 to 5. I was trying to get it to loop through 1 through 5 until the column count reached the end (30), then 6 through 10, etc. until 20 through 25. The code below is a python code block for calculating a field in model builder. I tried a bunch of things, but no go. I'm sure it's probably something simple but I can't wrap my head around it.
y1=0 c = %Number of Columns% # number of column blocks count = 0 count2 = 0 def autoGrid(): global y1 global count global count2 if (count <4): #main counter y1=0 for i in range (1, 4): count += 1 return count else: # step up counter y1 += 5 count = 0 count2 += 1 # counts the columns return y1
