As indicated in my original thread but this will depend upon the polygon configurations prior to the initial buffer. the outcome would depend upon the original polygon configuration.  do you have any images of pre-buffer...buffer and ... negative buffer that demonstrates your situation.  It may be a case of getting too exhuberant in your buffer values, both positive and negative...and it might take a few passes to obtain what you want.  So pictures would help along with gap details and buffers used. ...

did you perform the negative buffer? after the initial buffer? ... View more

if hundreds to one is what you want, have you tried the following 1  estimate/measure the gap between the polygons to get some sense on the space you need to close (ie say 10 meters) 2  buffer the polygons using the dissolve option, using a buffer width slightly larger than your estimated gap in 1 (say 5.1 meters).  At this stage you should have one big polygon with no gaps. 3  negatively buffer the result in 2 ( ie -5.1 meters) This should hopefully, but no guarantee return what you want, but this will depend upon the polygon configurations prior to the initial buffer. ...

what version of arcmap? is the destination field a text field?  It should be since splitting a strings results in string, if you want numbers, then you need to "int" the resultant split if placing in a short or long numeric field ... View more

a fishnet only makes sense if you are using/creating projected data (eg. UTM, state plane etc etc).  If your coordinates are in meters, simply "do the math" to get the results in feet.  If your data are in decimal degrees for your dataframe, use a projected coordinate system for it and make sure that the outputs are projected. ...

You will note that your origin_x variable is a text parameter (ie GetParameterAsText), hence, you need to cast it to a float value before performing any math operations using it.  This line: origin_x = origin_x/(180/pi) should be origin_x = float(origin_x) / (180 / pi) You will need to correct the others in the same fashion. ...
