2 Replies and 2872 Views Class Statistics with Area Units in ENVI 5.3  2872  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 https://www.dropbox.com/s/wg934vjrhi7o5h9/envi51.jpgdl=0 https://www.dropbox.com...

1 Replies and 1650 Views SPEAR pansharpening not using right temp directory  1650  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, Alex ENVI 5.2.1 x64 Windows 7 x64 Enterprise

Is there a built-in procedure, or do I need to code around something Thanks for any tips, Jared

3 Replies and 1851 Views Creating vectors within ENVI  1851  3 Started by  Deleted User 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

6 Replies and 1981 Views Stretch with Nodata values in Envi 5.2  1981  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

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

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...
