Hi,
I've a tiny question. Is there an annotated river dataset available? By
'annotated' I mean that rivers are ranked by a sort of relevance/size/length or
whatever. The problem is that I have an huge SpatialLines object called
'rivers' which shows ~23200 rivers but I have to draw a map which
Dear list users
I frequently use, and rather like, the worldHires map in 'mapdata'. The
resolution is quite good (compared to the 'world' map).
However, by overlaying some data on a worldHires map (at around long =
25.7 and lat = 70.9) I discovered that the map was quite inaccurate. The
Dear list members
I would like to calculate the madogram but in the
libraries I'm using (gstat) it seems not possible.
Have you any idea how I could do that ?
Thank you in advance for your help...

Hello seba,
With library SpatialExtremes [1] you can perform madograms with madogram()
function. Additionally, you can perform other alternative measures with this
library.
Cheers.

the one with scale ranks and tappering has some metadata which might
relate to size...
Ah, yes. Thanks a lot!!
This kind of data I looked for :)

Hello Freddy
Thank you for the quick reply. I'm going to give a look
to the library!

The absolute length can make sense of course but if I need also
the largest rivers of a smaller island then this fails or it's much
more tricky to handle/select.
Not really. You could for

Dear Laure,
If this is still actual, here are few tips on how to aggregate continuous
information (rasters) given some polygon maps.
-
# obtain a polygon map e.g. World countries:
load(url(http://spatial-analyst.net/DATA/WorldPolyCountries.Rdata;))
Hello all,
I have gridded data which I loaded using the readAsciiGrid function.
x - read.AsciiGrid(data.txt, plot.image=TRUE).
image(x)
This works OK but how do I:
1. know what values are assigned to which color/shade
2. change the color template e.g. rainbow
3. insert a color bar?
I can use image.plot()

Thanks very much for the help Sam and Roger.
I ended up using Sam's method which worked great, though seems to
require the offset and scaling factor to be calculated on the output
RasterLayer following creation. There is probably a method to apply
these directly, but I haven't figured that
Hi all,
is there a way to convert Military Grid (MGRS) coordinates to lat/long
using R's spatial packages? Thanks for any advice you may have!

Hi Nils,
Likely via the spTransform function in the rgdal package.

But I believe a user-written wrapper would be needed to translate MGRS
first to +proj=utm with zone number, or Universal Polar Stereographic near
Poles, 100km square IDs, etc. Scanning
