Are centre coordinates or upper left corners used of x, y for SpatialPixels?
Dear all, I'm working with satellite images in R and plotting them via the code below. I was wondering whether coordinates (spatial["x"], spatial["y"]) are used as centre coordinates of the pixels in the GRID? In this script; spatial["x"] & spatial["y"] are the centre coordinates of the satellite image pixels. I'm asking this because some

graphing netCDF files
Hello I'm working with a large hydrological data set stored in a netCDF format. The file stores x and y coordinates in the UTM projected coordinate system, yet when I use image to graphically display the z variable, the image is distorted in the sense that it does not plot the map in the correct spatial organization. I'm wondering if I need to define the projection of the netCDF file

Hi all, I am using LLVM compiler and CodeGen for generating ARM binaries. I was going through the code for ARM backend. I noticed that the ARM Condition field( Bits 31-28) is generated by converting the conditions used in icmp and branch. For example, if I have following C Code int a,b,c,d; c = a+b; if(c==0) d = a + 10; Then I get ( Assembly Instructions with opcodes only) add *cmp*
