Shapefile problems 1887 1
Started by Deleted User
I am trying to automate a process by creating an IDL program. As part of this process I have to convert thousands of points in text files into Shapefiles (polygons). I am able to create the new Shapefiles, however they don’t have any data. Here is the test code that I am dealing with:
PRO shapefile
myshape=OBJ_NEW('IDLffShape', FILEPATH('test7.shp', SUBDIR=&91'examples', 'data'&93), /UPDATE, ENTITY_TYPE=5)
new_vertices = &91&910.0,0.0&93,&910.0,1.0&93,&911.0,1.0&93,&911.0,0....

IDL ENVI Program Interaction 1890 0
Started by Deleted User
March 17, 2005
Hello,
I am trying to write a program to calibrate AVHRR data using IDL 6.1. IDL, I believe, uses some built in ENVI 4.1 functions to actually process the data. I am new both to IDL and ENVI and am not sure if what I'm saying is fully correct.
The following program opens a file that has a list of all the files that need to be processed (called 'inputFile') and processes them using the ENVI commands. The skeleton of this program was taken from an example (ENVI_AVHRR_CALIB...

Problem reading HDF5 file from library 1.6.2. 1895 0
Started by Deleted User
I have trouble reading HDF5 files built with library 1.6.2 using IDL version 6.1. Looking forward for the next IDL version 6.2 version to include upgraded routines able to read compressed HDF5 files (what I would expect), in the meantime I would like to know if there is any mean to solve the problem. Any suggestion will be greatly apreciated. This is relatively urgent.

3D data line analysis 1919 0
Started by Deleted User
I am trying to write a widget program that allows the user to draw a line over a 3D data set (plotted in 2D with intensity as color) and have the program generate a separate 2D plot of intensity vs. position on the line they drew over the original 3D plot. Any pointers Iam very new and can barely write a widget program. I know how to get the x and y position of the cursor, bu beyond that I can't make out much.
Thanks.

I'd like to ask if anyone has done the following operations in either ENVI/IDL/NITF Module.

Sine wave for Curvefitting 2042 0
Started by Deleted User
I would like to know a way to fit a sine wave and get the function to return the fit parameters.
The curvefit function in IDL calls a user defined function but it does not fit any phase. It fits a sine wave with only the initial value of the phase.
y = A B Sin(Cx)
A = Axis of rotation
B = Amplitude
C = Phase
My data just has half a sinogram.
Thank you,
HB
