Compare two images with different size 1637 2
Started by Deleted User
Hi, I want to link two images and compare them in the same region. The two images are taken from the same scene but they have different sizes, so I can't really link them to the same region and sometimes it will even go out of range. Is there anyway I can do this
Also, I noticed that on the top bar of the scroll window, there is a number in the round brackets. And that number of the two images is different. What does that number stand for
Thanks!

When I later create a color transformed image from HSV to RGB, using hue and saturation from the multispectral image and Val from the panchromatic image, to do a panchromatic sharpening, then it doesn't work in some areas, in others it works just fine.
On the other hand, if I convert from RGB to HSV before I resize the image to fit the resolution of ...

bytscl and converting between data types 1505 5
Started by Deleted User
Hi,
I currently am using a program that requires two images both with a data type of 1 (as indicated in the header file) and then performs image processing with the two images. When the program was originally written both of the images used were from the same sensor, so they were both the same data type (1) but now I'm trying to use one from that sensor and one from another sensor that produces images of data type 2. I am trying to convert that second image from data type 2 to data type 1 but...

ENVI Mosaic Tool 996 3
Started by Deleted User
Hi, I'm looking for detailed information on the Mosaic tool in ENVI. I have mosaic several images together using the ENVI Help files; this is relatively easy. I know want to understand exactly what the tool is doing with my data. I'm guessing it is an empirical method of sorts. Is it using polynomials or linear regressions Does anyone know where I can find this sort of detailed information

map coordinate converter - different version of ENVI, different results 1086 1
Started by Deleted User
Hi,
I am a little confused. Generally I work with SARscape on high resolution TerraSAR-X data. I usually need convert map coordinate to generating ground control point. I have updated ENVI from 4.8 version to 5.0 and I noticed that results from both version are different. Difference is about 20m and it is significant during geocoding HR data.
I convert from UTM 31N ellipsoid ED50 to UTM 31N ellipsoid WGS84. It seems that conversion using ENVI 4.8 is proper. Can anybody know what is the c...

MOLA data in ENVI 5.0 1143 1
Started by Deleted User
I need to analyze geospatial data from the Mars MOLA dataset in ENVI 5.0 in Windows 7. I tried opening MEG500N180GB.IMG, but ENVI doesn't seem to recognize the file type. I'm also trying to open a file in a folder named mola128_88Nto88S_Simp_clon0, which I downloaded from the USGS Pigwad site. It has a file named w001001.adf, which is 1.6 gb. Given the size of the file, I'm assuming it's map projected, but ENVI doesn't open it either. Thanks!
