Dear List, Is there a color palette avaliable similar to what is used in satellite ocean color imagery? I.e. a gradient with blue on one end and red on the other, with yellow in the middle? I have tried topo.colors(n) but that comes out more yellow on the end. I am looking for something similar to what is found on the CoastWatch web page: http://oceanwatch.pifsc.noaa.gov/imagery/GA2009281_200928...

Greetings! Is there in any package for R which can help me generate madogram, rodogram, semi-variogram, cross variogram from landsat imagery. I intend to select portions of large imagery (i.e., obtain subsets) and generate the above said texture layers. A simple Google search led to me a result suggesting SpatialExtremes for generating madograms. However I am not sure about its capability to generate one for image layers. I am a beginne...

Hi All, I tried to apply "server=domain" for a samba server domain member with samba-3.0alpha23 and samba-3.0alpha24. In each cases, " ads_connect: Connection refused .." message appeared when trying to join the domain. But "net rpc testjoin" says ok. The main point of this mail is that " smbclient -L mysamba -U username" will work on

Hello I am running a net work with a NT4PDC a NT4 BDC and attent to add samba BDC. I am following the brief section 28 of the Samba-Howto collection for samba head/3.0. * Adding the samba server as a BDC from NT server manager seems OK * Getting, recording domain sid is ok (see below) > rpcclient NT4PDC -U Administrator password: > lsaquery domain IMAGERIE has sid blablabla > net

Hello all- I have a question related to encoding. I'm using a seperate program which takes either 16 bit or 8 bit (flat binary files) as inputs (they are raster satellite imagery and the associated quality files), but can't handle both at the same time. Problem is the quality and the image come in different formats (quality- 8bit, image- 16bit). I need to switch the encoding on the quality files to 16 bit, without altering anything else (they are img files right now)....

...itical species and include a mention to relevant biological characteristics (ie., shade-tolerant, evergreen etc.). Sometimes I also include another (reduced) figure, for example a reduced map indicating the geographic location of some sites, and or time-series of the phenology as shown by satellite imagery. Another example of adding ancillary information to an statistic graphic is adding field-collected information to a graphic that displays results from the analysis od remotely-sensed imagery. Thanks, Paul, for you work at improving the (many) R graphic capabilities. Agus Dr. Agustin Lobo Insti...

Dear R Helpers, Currently I'm working with the ts package of R and created a TimeSerie from pixels extracted from satellite imagery(S10 NDVI data, 10 daily composites). I'm trying to decompose this signal in different signals (seasonal and trend). When testing out the STL method is says => Only univariate timeseries are allowed, but the current Timeserie I'm using is univariate! => The problem is probably that th...

...ck the DOS box happens to pick the same ephemeral port number after a reboot that it was using before, it will get RST. The DOS app will then retry, causing the DOS TCP stack to pick a different ephemeral port, so it will succeed. A different fix is to exploit the real-time nature of video camera imagery: if your Python app goes more than a second without receiving an image frame, it can presume that the DOS box has disappeared again, and drop its conn. By the time the DOS box reboots, TIME_WAIT may have expired, so the DOS box might reconnect without a problem. You may wish to reduce tcp_fin_tim...

I was hoping I could get some help with an import question. I work with remote sensing imagery which commonly comes in binary form in various interleaving formats (byte interleaved by line, by pixel, etc..). These files are 2d spatial x B bands in size, and I want to be able to extract the band values from various pixels (so each line of data into R would be one pixel x B bands). What'...

Hi, I have a dataset of dimensions 50 x 15000, and tried to use princomp or prcomp on this dataset with 15000 columns as variables, but it seems that the 2 functions can;t handle this large number of columns, anyone has nay suggestions to get around this? Thanks --------------------------------- [[alternate HTML version deleted]]

Hi there, I''m just implementing backgroundrb to see if I can offload some "processor intensive" areas of my rails app (generating PDFs with lots of imagery in them, using rFPDF and rMagick as well). So far I''ve been able to figure it out fairly quickly....it''s a pretty cool tool! Some questions though: First: I''m running the basic cron-job script to call GC every few minutes via cron, and generally while memory usage...

Wine could bring this to anyone regardless of income level, with as little as red/green, cyan,red, blue/yellow,cross-eyed/parallel layering, or as advanced as the use of lenticular monitors, polarized projection or lcd shutter frame synchronization. The only thing I believe that has kept this f...

...d obviously the larger the R^2 gets the better the predictive ability but over what range does this r^2 operate? As it is not unexpected that some of these models would have poor predictive accuracy as part of the larger project around this work is to say finer resolution remotely sensed satellite imagery is needed to derive the climate variables etc being used to predict species abundance. My question is probably a bit like how long is a piece of string but if anyone could offer some guidance on what constitutes a good / very good / bad / very bad r-squared value for random forest it would be most...

...er understanding the differences in using many classification trees to improve classification rates. I'm also interested in finding out what I can do in R and which methods will allow prediction. Can anybody point me to a citation or discussion? Specifically, I want to classify remotely sensed imagery where training data is extracted on class membership by the user. That training data (usually spectral bands and categorical data - e.g., soil type) is classified (using rpart for instance) and then the resulting tree is applied to the entire image. This results in a classified image that can then...

We are a CentOS shop, and have the lucky, fortunate problem of having ever-increasing amounts of data to manage. EXT3/4 becomes tough to manage when you start climbing, especially when you have to upgrade, so we're contemplating switching to ZFS. As of last spring, it appears that ZFS On Linux http://zfsonlinux.org/ calls itself production ready despite a version number of 0.6.2, and
