shrug-l: Spatial Extent problem using the cost distance functionwith point and raster datasets.

[Wolfe, Heather]

There is a really easy way to do it. 
 
-make a copy of the shapefile (needs to be a shapefile- it it's a
feature class export to a shapefile)
-delete the  .prj file
-find or make another shapefile that is the same projection but larger
extent. for instance, if I wanted one that was a little larger than
seminole county, I would get a SPFLE county file of all the florida
counties, select seminole and all the counties around seminole, and
export them to a new shapefile . 
-Import the projection from the larger shapefile (the extent will come
also)
 
you can also play around with the extent settings,  but that can be a
little messy. I advise doing it the easy way.

Subject: shrug-l: Spatial Extent problem using the cost distance
functionwith point and raster datasets. 



A colleague is using the cost distance function with a raster and a
point dataset as inputs. The extent of the point dataset seems to be
controlling the output. How can he change the extent (i.e., we want to
extend some distance beyond the point dataset extent). 

 

Any help is greatly appreciated (he wants to embed this within a DLL).

 

Thanks
