I have nc files for global soil moisture,here is one file https://echange-fichiers.inra.fr/get?k=f9DDllPKdUKs5ZNQwfq from the metadata ,the projection is cylindrical and the resolution is 25 km(it is based on authalic sphere based on International 1924 ellipsoid).As I want to compare with other data, I have to make them identical. - my other data are in WGS84 with 0.25*0.25 degree resolution and extent -180, 180, -90, 90. So I want to re-project the data I hav...

The volume of a polygon = 0. Polyhedra have volumes. This may be irrelevant, but if the lake is cylindrical == constant cross sectional area at all depths, then height doubles when the volume does and vice versa. Otherwise you have to know how area varies with height or use more sensible approximations thereto. Cheers, Bert On Tue, Dec 5, 2023, 20:13 javad bayat <j.bayat194 at gmail.com> wrote:...

...wer left. If possible, I'd like to use Albers conic projection, or something similar. Thus far I have tried using the maps package with its state database (which omits Alaska and Hawaii) and the gmaps package (which places an inset for Alaska in the lower left and uses a projection [Miller cylindrical?] that distorts states along the northern and southern fringe). I would be very grateful for suggestions about alternative approaches. John -- John P.

Running R version 2.6.1 under Gentoo Linux, I'm trying to produce a thematic map of the USA using the gmaps package. The result thus far has two problems from my point of view. First, the projection (Miller cylindrical?) elongates southern states and flattens northern ones unattractively. I'd prefer Albers conic projection or something similar. Second, the inset for Alaska is placed south of the contiguous states. I'd prefer to put it north of them. I would be very grateful to anyone who could sugges...

...The biggest problem is that there is very little discussion on multivariate distributions. Noting that multivariate distributions play a critical role in statistical theory, plus are gaining an increasing number of applications in various fields. I saw no discussion of distributions with circular, cylindrical, or spherical sample spaces (and for that matter the descriptions of bounded and unbounded are wrong). No discussion of copulas and no discussion of distributions that mix discrete and continuous random variables. Plus despite saying that your organisation supports nonparametric approaches, there...

Hello, there!   Basically my problem is very clear. I would like to take a (numerical) integration of a function f(x,y) which can be quite complex of x and y, over a disk (x-a)^2+(y-b)^2<= r^2 (with r constant). However, after some search in R, I just cannot find a function in R that suits my purpose. Function Integrate applies to one dimensional, and adaptIntegrate to rectangle. In my case, it

Dear all; I am trying to calculate the volume of a polygon shapefile according to a DEM raster. I have provided some codes at the end of this email.I dont know if the codes are correct or not. Following this, I have another question too. I want to know if the volume of the reservoir rises or doubles, what would be the elevation? I would be more than happy if anyone could help me. Sincerely "

Dear all, 1. How can I compute the intersecting area between 2 polygons ? 2. I have polygons with coordinates in decimal degrees (i.e. 13 deg 30 min = 13.5 decimal degrees). I want to compute their area and get the results in square meters or square kiometers. Can anyone give me a conversion coefficient or a pointer where I can find this information (sorry for this off topic question) ? Thanks

Hi, I guess this is a good time to start putting together a wish list for a video codec. I see that for audio the compression is around 10X for reasonable quality. I am sure this will start its own thread of conversation. For video you can do 40X fairly easily and the big task is to go to 80X or 100X with reasonable picture quality, say, a peak luma SNR of more than 30 dB. Uncompressed
