search for: erosion

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?...

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 SpatialGridDataFrames... Thanks a lot Maarten -- View...

...hether 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 state of the basin, that is, whether erosion is as strong as rock uplift, erosion is smaller than rock uplift, or erosion is greater than rock uplift. I am thus to test 4 situations: Situation 1: a linear model is inappropriate for describing the data, the scatter is too large, and thus a linear model is unfit to explain the data. Situation...

...laced in the ReaderWriter component. This is the 2nd component in the layering: Driver ReaderWriter Passes Core The problem is that Core depends on these files. So in my opinion, they belong to that Component. The greater impact here is that once core starts depending on ReaderWriter, architecture Erosion will happen. This would obviously not be a good thing, since the current design is fresh and clean. I would love to supply patches, but am having issues getting lld to build under Ubuntu 12.04. (but that's another story ;) ). I've posted the updated architecture view here: http://www.c2la...

...like THP CoW more than swap. A fine point: overall, the desired behavior is "migrate", not CoW. That's important. Migrate means that you don't leave a page behind, even a read-only one. And that's exactly how device private migration is specified. We should try to avoid any erosion of clarity here. Even if somehow (really?) the underlying implementation calls this THP CoW, the actual goal is to migrate pages over to the device (and back). >> >> When migrating in: > > Sorry for my fat finger, hit sent button inadvertently, let me finish here. > > Wh...

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

G'Day All, We have been supporting linux as a side business for a while (because we use that skill set in our own value chain internally) and we are now going to start targeting the wider local Chinese market and not just the foreign companies and joint ventures. As such we expect to see tremendous growth in this market segment this year due to the quickly dwindling support of local
