Run FLAASH in batch mode / Adjacency Effect 2094 1
Started by Deleted User
Hi Harris Team,
I would like to write some IDL scripts to automatize the preprocessing process of Hyperion images. Please, could you give me more details about running FLAASH in batch mode
And my second issue is related with adjacency effect setting in FLAASH. I would like to know what is the horizontal range (km) of the adjacency effect set as default in FLAASH, and if there is an option to set a different value
Thanks so much

Class Statistics with Area Units in ENVI 5.3 2846 2
Started by Deleted User
In EnVI 5.1, when you run Class Statistics, you will see the area covered by each class in "Class Distribution Summary," with the default unit being meters squared (m^2). You can even go to Options>Class Summary Area Units> and choose different units. When I run 5.3 however, the Class Statistics windows no longer displays m^2 results for each class. Where can I go to easily find these values in 5.3

SPEAR pansharpening not using right temp directory 1629 1
Started by Deleted User
Hello,
I've set a temp directory in File -> Preferences. However, the SPEAR Pansharpening tool keeps using the old temp directory, even after restarting ENVI. My C drive is full, so need it to use the D drive instead, but it's refusing to do so. I'm dead in the water until I can fix this. Any thoughts
Thanks,

Creating Array with Raster Band Names in ENVI 5 1602 2
Started by Deleted User
Hi all,
One task that has eluded me for the last few days is how to create a string array of band names (&91'Elevation','Shaded Relief','Roughness'&93) from a raster image after it has been opened in ENVI. Is there a built-in procedure, or do I need to code around something
Thanks for any tips,
Jared

RMSE between two image with two different pixel size? 1779 1
Started by Deleted User
Hi,
I am trying to georegister two images, the base image has the resolution of one meter and the warp image has the resolution of three meter. My question is whether the reported RMSE has the unit of the base image (1 m pixel size) or the warp image (three meter pixel size).
Thanks

Right mouse button 1738 5

Hello,
I can't seem to generate a right-button signal to ENVI. I can find no doc for how to do it with a one-button mouse and I've tried all the special-key combos. I do have a 3-button Logitech mouse, but can't get the config for that to be recognized by ENVI. Any help appreciated!

Creating vectors within ENVI 1831 3

Hello,
I have a file containing coordinate information - points, polygons. I have created a custom file reader to read the file and extract the coordinates and other information. I would now like to create and ENVI vector layer from the extracted data and display the result in ENVI. However, I don't see a way to do this in the ENVI API. Is there a way to create an ENVI vector file programmatically Or do I need to use the old ENVI_EVF_DEFINE_INIT

Stretch with Nodata values in Envi 5.2 1961 6
Started by Deleted User
Hello,
is it possible that the new versions of Envi (>=5) always include the NoData value in the stretching even if it is specified in the file
I have a Landsat image with a lot of NoData values (-9999) and I only see my data as black and the NoData areas as white... no stretch can change this. Custom stretch does not work (doesnt show me any data). In QGIS or the classic Envi, its no problem!
Cheers, Kim

Reclassification Raster in ENVI? 3261 2
Started by Deleted User
Hi,
I have derived slope using SRTM 1Arc Sec DEM. Now, I am intending to reclassify its values in 4 classes to rate and rank them for my suitability analysis. For example, Slope having 1-15 degree will be assigned to Class-1 and so on. I am using ENVI 5.3 and have searched for the required tool but didn't found there.
There might be Band Math expression to do the job, how would I classify it

Band math : Intersection between two masks 2441 3

Hello
I'm using Envi 5.3 version, and I want to do an intersection between two masks:

So I'm using this two mathematical function in Band Math:
b1*b2 in this first case, every pixel of my new image have 0 as value. I don't understand how it's possible because 1*1 is supposed to return 1.
and I also use:
float (b1) *float (b2)
I don't have any float in my two original masks, but this function returns a random partition of 1 value, but not the corre...
