Maximum number of tiepoints in GeoTIFF 1632 0
Started by Deleted User
I have been using WRITE_TIFF to write weather satellite images in GeoTIFF that are in their native scan space, but have lat/lon tie points every eighth pixel in the X and Y directions (can be 100,000 tie points or more). However, when I try to write that more than 65536 elements (65536/6 tiepoints) into the 'MODELTIEPOINTTAG', not all of them are stored into the GeoTIFF. It appears there is an integer somewhere that is rolling over. Is this an IDL problem or a limitation of the GeoTIFF forma...

Speeding Up Oracle DataBase Access with IDL DataMiner 1504 0
Started by Deleted User
Hello-
I've been using DataMiner to retrieve records from a large Oracle DataBase.
The DataBase is several gigabytes in size; A simple query can often take a
half hour to complete. For more complex larger queries, it's not uncommon for
it to take a few hours to completely finish. In the meantime, the IDL window
goes unresponsive, displaying a 'Not Responding' message, until the task is
finally completed, then the window gets updated.
1) First of all, is there a way of preventing the ...

Interpolation of 2D images to build 3D volumes 1745 0
Started by Deleted User
Hello ,
I am using the INTERPOLATE command to compress a stack of 2D (thresheld to binary values) images into a Vol files. I have noticed a fair amount data loss and have been searching for the source of the INTERPOLATE command within the IDL library with no success. I had hoped to rewrite the current ( nearest 8 pixel , weighted, meaness and brightness) to one that incorperated a catch for the existence of any pixel value, so as not to lose that data. (somehow, still haven't figured it out ...

IDL memory problem 2071 2
Started by Deleted User
Hi,
I've recently installed a software package for idl 6.0 on my Mac (OS X Tiger 10.4.1). The package often spawns new shells. At one point I get the following error message:
Unable to allocate memory: to expand environment.
I've been searching on the internet for the meaning of this message, but haven't been able to find anything, except for one Windows related problem.
Does anyone know what the source of this error (message) could be
Cheers,

Hi,
By mistake, I stored 1000 CCD images with wrong headers (*.hdf format). Now, I want to change the name of files only, not the creation time ot dates etc. I would really appreciate if anybody can help me to figure it out.
example'
Np1_Nomask05567.hdf to Np1_Nomask06567.hdf should be changed to
Np1_100ummask05567.hdf to Np1_100ummask06567.hdf

where() function not working properly 1430 1

Hello All:
I have a N by 2 matrix as follows:

FABSCoordinates&91*,1&93=&91m1,m2,m3......mj&93

Is it possible to create an accurate, filled contour plot with data which does not vary smoothly
Im trying to create a contour plot of trend data. I would like to add some shading in a single colour to indicate where the trends are significant, i.e. I have a 2-d array filled with 1s and 0s, and call contour with this array and the /cell_fill or /fill keywords.

MNF and masks 1623 0
Started by Deleted User
I've built a mask that surrounds my region of interest, then use the mask within the MNF application to zero out those masked areas and force the application to only consider my ROI. This works fine and the MNF results show that the masked areas have values of 0, while the ROI has distinct positive or negative values. However, when I invert the MNF, choosing only the bands I want, the result gives an image that has a spectral profiles for those regions which I had previously masked - thought tha...
