I remember doing some really cool stuff back when I worked for the provincial government and was still in ESRI's good books (I think I met Myron down at UC2001) :) A lot of it was based on this guy's work: http://gis.esri.com/library/userconf/proc98/PROCEED/TO850/PAP842/P842.HTM <http://gis.esri.com/library/userconf/proc98/PROCEED/TO850/PAP842/P842.HTM> With some influences from ShadeMax: http://arcscripts.esri.com/details.asp?dbid=11641 <http://arcscripts.esri.com/details.asp?dbid=11641>
After the FME conference, I was really hyped up about raster and was going to put in some requests... Unfortunately, work has got in my way; haven't been able to think about this clearly... Here's a dump of what's in the back of my mind: - common functions on DEM (slope, aspect, flowaccumulation, hillshade). - RasterReclassifier: like combination of a RasterCellValueReplacer and a VariableRasterClassifier, allowing specification of the values to replace the bands with arbitrary values - support for other color models (HSV especially for painted relief) - general purpose RasterCalculator. This would be like the expression evaluator, but could also take multiple inputs. Like... Output = Input1 * (Input2 / 255) - advanced functionality in RasterCalculator. OK, this is when it gets mindbending. Allow RasterCalculator to work in a cell-based mode with offsets. Like Output [] = (Input1[-2,-2] * 0.25) + (Input1[-2,-1] * 0.33) Sorry Dale, afraid I can't provide a business case on this one. Just something that I've been missing in general since I no longer have Grid to play with. Here's a post (with a comment from me) on some of the more advanced raster analysis I'd love to be able to do with FME: http://gismatters.blogspot.com/2006/10/simulation-and-modeling-geoprocessing.html <http://gismatters.blogspot.com/2006/10/simulation-and-modeling-geoprocessing.html> Jason ________________________________ From: [email protected] on behalf of Dale Lutz Sent: Tue 2007-03-06 9:16 PM To: [email protected] Subject: Re: [fme] Re: Raster Technical Bulletin Hi Ron, > > Just wondering is the a method in FME to produce shaded relief > images from > > these datasets? Now there is a very fun idea. It is true from a business point of view it may be hard to justify doing this, and its not on our roadmap, but as a weekend project it would be great to do it. I believe I wrote software like this as part of a university project in 1988 during my undergrad at the U of A -- I took a graduate level remote sensing course on a whim in my last year of Comp Sci, and we did stuff like this in FORTRAN I think.
