Extent Tool, eg for Parameterizing Fishnet

Reported by: bbest Owned by: jjr8
Priority: Low Milestone: Unscheduled
Component: Tools - Spatial Analysis Version:
Keywords: Cc:

Description

Needed to extract extent of a study area (eg lower-left corner) and calculate the number of rows and columns in order to use the  Create Fishnet tool, like the following output from an Albers-projected study area:

lower left corner
  x: 542081.140700
  y: 611062.131800

number of
  columns: 416
  rows: 489

The attached script could be enhanced to a simple tool for these type of outputs, which could be strung along in a ModelBuilder window as parameters to tools like Create Fishnet.

Thanks for the suggestion. One question. The Create Fishnet for Points tool can do this automatically already. Therefore this new tool would be useful mainly if you were working with lines or ploygons. Is that what you have? Or were you working with points and there was some reason Create Fishnet for Points did not work? Thx.

Replying to jjr8:

I have a study extent (polygon shapefile of a stratum in coastal waters of BC) and needed a grid of polygon cells registered to the entirety of that study area (for doing predictive density surface modeling), and not the points (sightings). I can imagine others with a similar use-case scenarios based on a study area of interest.

Replying to bbest:

Ok I will see what i can do to enhance the input parameters to make it more convenient. For now I'm not going to schedule this for MGET 0.7 but we can look at a future release. (I am probably going to scope 0.7 down to be a mini-release of enhancements targeted specifically to the CoML meeting, plus additional bug fixes reported by users and some small stuff I need for other projects.)
