McIDAS-V LOCAL SERVER RELATED

Hi all I was trying to use the mcidas-v local server capability to access insat3d data via area file interface. It works nicely. I wrote some code to access that local server via visad api outside mcidas-v to save those datasets as areafiles. It works nicely. My question, the moment I change hostnam...

area file data choices

Hi all

I got a GOES total ozone area file.
When I open in idv/mcv, I find 3 data choices: RAW,BRIT. and TEMPERATURE.
I am opening via file chooser and not local ADDE server or remote server.
These datachoices I feel are not relevant for total ozone atleast.

Regards
Ghansham

Re: How to make a perfect customized MAP (1km max error)

Hi

I have a query. When you say, that you need map at pixel scale.
Does the "pixel", you refer to is the pixel of radar image.
Long time back I wrote some code to zoom to image resolution.
That may be useful.

Kindly clarify meaning of pixel.

Re: mcIDAS EU in McIDAS-V

I agree with your observations completely. The basic reason fir increasing number of colors is to get similar results as McX as currently there is no support in McV for bilinear color enhancements. I think its high time that such functionality should be built in McV. Actually there are methods in Vi...

Re: mcIDAS EU in McIDAS-V

It has to be first case I feel because of the limitation of mcidasv of applying the lookup tables linearly. You can try a simple exercise to find expected and calculated values of indices of color table for a given temperature. You may have to interpolate a few colors when you create table with leng...

Re: mcIDAS EU in McIDAS-V

Exactly what I was also thinking on same lines.
Creating a lut of 336 entries ((330-163)*2).

Please send me updated code whenever you get time.
No hurry..

Thanks a lot.

Re: mcIDAS EU in McIDAS-V

Thanks Joleen. Thats what I was looking for. Couple of points: 1. Please attach a sample input CT. 2. Is the input CT hacing 256 colors? 3. Does the number of colors get reduced to 167 in the output color table? Wont this make the output image reduce the variation in image and make it flat as number...

Re: mcIDAS EU in McIDAS-V

Hi all The 256-entry color table if we generate using the indices provided, is not applied correctly as for calculating those indices, the function is not same. It has two parts, 1. < 176 2. > 176. McIDAS-V/IDV apply linear lookup tables. VisAD has capability to apply such color enhacements using Fu...

mcIDAS EU in McIDAS-V

Hi all Do we have a java class as part of McV code base that generates color table following the McIDAS EU interpolation logic given the break points and its corresponding values. Say this: EU TABLE WV_BLUE Brightness Blue Green Red min max min max min max min max --- --- --- --- --- --- --- --- 0 1...
