Hello! I need a function to compute the erosion of a binary image by a structuring element. I need the structuring element to be a ball of a given radius. As far as I know the libraries adehabitat and spatstat include functions of mathematical morphology but I couldn't find a function which computes the erosion by a ball. Any idea? Thanks!

Hi, I just imported two raster maps into R using the SPGRASS6 package, one containing elevation data and the other containing an erosion index: Kar_inc <-readRAST6("Incis_Kar", plugin=FALSE) Kar_dem <- readRAST6("DEM_Kar", plugin=FALSE) I just wanted to make a xy plot of erosion parameter vs elevation. How does this work? I don't get how to handle

Dear R-users, I've been reading a bunch of things on linear models but cannot quite find a clear answer. How can one determine whether a linear model is significant or not? For background info, I am modelling the response of topographic slope to the distance of a catchment's outlet. Some guys have shown that if there is a significant fit to a linear model, one can deduce the dynamic

Hi, I've been following the changes in LLD's software architecture. Recently a new file was added: Alias.h In this file, the curret Atom set is extended with an AliasAtom. While the change seems innocent enough, it has some nasty potential. Simple.h and Alias.h are placed in the ReaderWriter component. This is the 2nd component in the layering: Driver ReaderWriter Passes Core The problem

The inverted dependency of Core to ReaderWriter via Simple.h was already present. My idea was to fix the problem before it gets bigger. My proposal would be to move Simple.h and Alias.h to Core. Similar to UndefinedAtom.h etc. It would be even nicer to make the naming consistent as well, since there already is UndefinedAtom.h SharedLibaryAtom.h etc Maybe: SimpleAtom.h AliasAtom.h Moving the file

Dear R users, I wish to run spatial point pattern analysis (e.g. pair correlation function, mark correlation function) for which I need to create an observation window (window=owin) from which the spatial analysis is generated. The command I used to create this observation window as follows: X1<- ppp(x, y, window=owin(c(80.58,144.96),c(101.06,165.13)),

Good day, all, I'm trying to transfer a 174M file to a system with 1.2G free. Other files in the tree come over just fine, but this transfer dies partway through: rsync -avvz -e ssh --partial --progress server.with.the.file:/server/directory /local/directory opening connection using ssh server.with.the.file rsync --server --sender -vvlogDtprz --partial . /local/directory receiving file

However in China, IT is more dumbed down and is akin to "Computing Services", backup, servers, hosting, windows/linux/cisco/et al is what comes to mind. While this is all fine and dandy it is hardly IT and it is a very price erosive market (China and India combined) and seems to be destroying the local demand for real IT and everyones chance to start more off-shoring operations here in competition with India. The concept of technology being a support service to a greater operational goal and process (value chain) is qui...

I've run a new scan of LLD's architecture and it appears to be getting cleaner! There are still some upward dependencies however: - core depends on Reader and Writer - passes depend on Reader and Writer - ReaderWriter/PECOFF/ReaderCOFF.cpp depends on Driver.h The updated architecture can be seen here: http://www.c2lang.org/docs/lld_architecture_20140710.png On Tue, Jun 3, 2014 at 3:07
