Hi Ahmed, When reading from a ncdf file you can use the 'varname', 'lvar' and 'level' arguments - see the 'Details' section in the docs https://www.rdocumentation.org/packages/raster/versions/2.6-7/topics/raster <https://www.rdocumentation.org/packages/raster/versions/2.6-7/topics/raster> We can't tell what is in the ncdf file from what you report other

Dear R users, I'm currently trying to re-project a geotiff in another coordinate system. For instance, I have a tif image in UTM 19 zone which I would like to reproject into UTM 18. I was wondering if it was possible in R. Furthermore, I looked into 'rgdal' package, but I can't really find out if I'm doing the right thing. So far, here is what I'm doing: library(rgdal)

Dear list, I have to compare two digital elevation models in raster format (geotiff). I then have to calculate the differences in altitude for each cell and make some statistics (basic as mean, median, std, range but also more "advanced" as RMSE) on that. I do not know very much how to proceed: 1) is it possible to import the geotiff in R? If so with which package? if not which is the

Hi, Doing more search i've discovered package RGDAL that can write a geotiff file with projection. I saved a geotiff file in UTM projection and if i read the file back in R and check the projection seems that everything is OK. But if i load the file in ArcGIS (ESRI product) i get the warning that the file is missing spatial reference so it cannot be projected, but it is displayed correctly.

Hi, I have a matrix of data which i can vizualize as an image - for example. I would like to save this image as a geotiff file or at a tiff file with a world file which holds the projection of my data (ultimately the data represent a map of some sort). I know i can save the data as an ESRI grid, but i am not interested in that. I wonder if anybody knows about any code which will help me do

Dear all, I have a set of x,y,z points obtained from a lizard species and now I would like to estimate the three-dimensional use of space for this species. I know that 2D area I can estimate using adehabitat packages, but I don´t know how to estimate the volumetric space. Any help are welcome. Miltinho Brazil [[alternative HTML version deleted]]

*Dear experts,* Please excuse me for disturbing... Right now I am struggling with GLM a bit... Would you be so kind to provide me a solution on using nuisance variables. The problem is that I have data on Depression (volumetric measurements of different brain regions) and I want to include age, gender and education as nuisance parameters in the model. In the other words I would like to model the

Hello R users, Hope everyone is doing great. I have a dataset that is in .csv format and consists of two columns: one named Period (which contains dates in the format yyyy_mm) and goes from 1995_10 to 2007_09 and the second column named pcumsdry which is a volumetric measure and has been formatted as numeric without any commas or decimals. I imported the dataset as pauldataset and made use of

You may use the "geometry" package and the "convhulln" function. This will allow you to compute the convex hull volume of a set of points in a n-dimensional space. -- Guilhaumon Fran?ois Laboratoire "Ecosyst?mes Lagunaires" UMR 5119 cc 93 Bat 24 Universit?

Hello: I would like to superimpose vector polygons (state outlines) from a Shape file on top of a satellite image, imported into a SpatialGridDataFrame from GEOTIFF via gdal_translate and readGDAL. When I plot polygon and point shape files in R, into SpatialPointDataFrame and SpatialPolygonDataFrame, the two feature sets line up geographically, so it seems logical that a SpatialGridDataFrame

I know there is some integration between Grass and R available, but has anyone produced a link between R and MFWorks. I am considering Buying MFWorks (Windows) and it would be useful to know if anyone has written such a link.

GDAL Package for R http://sourceforge.net/projects/rgdal The R GDAL package is an interface for accessing Frank Warmerdam's Geographic Data Abstraction Library from within R. GDAL is capable of reading and writing a wide range of geographic data formats including ESRI grid format and geotiff.

Hi folks, My wife and I are taking a long weekend to celibrate our anniversary. I won't be around again until Wednesday to answer email or do anything else on Vorbis. Yeah, I know, I usually answer my email once a month anyway (so likely no one would notice me being gone), but just so folks know if anything really juicy comes up :-) I'll be merging my latest branch with mainline

Hi, I'm using Dovecot 1.0.5 on OpenSUSE 10.3. I run postfix/amavis/clamav on one host, postfix uses LDAP to identify whether or not users exist. On this same machine I was running dovecot, so I used dovecot LDA on Postfix master.cf (as mentioned on http://heinous.org/wiki/Virtual_Domains,_Postfix,_Dovecot_LDA,_and_LDAP#Postfix). Now I want to run Dovecot on another machine, how should I

Greetings, Summary: Has anyone else started a package (or have code) with the capability to write Vis5D-readable netCDF files containing irregularly-spaced data? I've recently put together what might be the beginnings of a (GPL'ed) R interface package to the Vis5D volumetric visualization program (http://vis5d.sourceforge.net). Vis5D is commonly used in the atmospheric science and

Hi, I'm trying to plot a set of geographical coordinates over the polygons in a shapefile, so I need to transform the coordinates to the same projection. I'm currently using the project function in the rgdal library, but I can't seem to figure out how to format the proj string argument correctly. (I made a couple attempts using http://www.remotesensing.org/geotiff/proj_list/ as a

Hi all, I am very knew to this R and Arcgis combination. I have already spent days attempting to find my answer but have failed, therefore could you please if possible explain any answers in simple form. I am trying to access Arcgis through R, following a few steps: 1) Set up working directory 2)connect to Python 3) import arcgis- however, when I get to the import stage it comes up with an error

Hi everyone, Here is a summary of what I am trying to do. Please take a look and let me know how can i complete this below mentioned objective using R for a large dataset. ** - *Objective:* - To calculate the number of points that fall inside each cell of a given raster - *Inputs:* - Raster data – Geotiff, approximate size: 4000 rows x 4000 columns - Points data –

Hi all, i have a SpatialPixelsDataFrame object, which is a result of kriging in R. What i would like to do is to convert this object to image (geoTiff) so that i could use it in Gis application. I have tried using this image2Grid function but it doesen't work. Here is the code : im<-image(pCir) #pCir is the SpatialPixelsDataFrame object which is the result of kriging, with var1.pred
