Hi everyone,
Does anyone have any suggestions on sampling a raster (NLCD land cover
map, 30 m res) using circular buffers centered on 100+ sample points?
The NLCD map has classifications such as high density urban, medium
density urban, crop, etc. The goal is to produce a data set with the
perce
Hi everyone,
I am attempting to convert points in DDD to UTM (zone 18) using
PBSmapping and I'm getting an error message.
The code and output:
library(PBSmapping)
dd_sosp <- read.csv("g:\\sosp\\2010\\sosp2010coord.csv", header=T)
attr(dd_sosp, "zone") <- 18
str(dd_sosp)
'data.frame': 109 obs
Hi everyone,
I've gotten closer to a solution but there's still something wonky going
on. Here's the new code I'm using
dd_sosp <- read.csv("g:\\sosp\\2010\\sosp2010coord.csv", header=T)
names(dd_sosp) <- c("X","Y")
attr(dd_sosp, "projection") <- c("LL")
sosp.utm <- convUL(dd_sosp)
Hi everyone,
Is it possible to create an adjacency matrix required for
WinBUGS/GeoBUGS in spdep from a csv file containing UTM coordinates?
I've gone through the spdep documentation and it looks like the
equivalent there is col.gal.nb? Is that right? I see where that object
is used but n
help! I'm going through your spatial book and it's really
good - lots of tips!

Hi everyone,
I'm attempting to do some spatial analyses with a relatively simple data
set and I'm running into some issues. Here's my code:
sosp09 <- read.csv("f:\\sosp\\2009\\sosp09.means.csv", header=T)
sp.point <- cbind(sosp09$x, sosp09$y)
colnames(sp.point) <- c("LONG","LAT")
