Hello,
my Name is Kai, 31 years old and student for Geographic Information in Germany. At time, i`m working with ENVI 5.1 and i want make an automatic mosaicking with georefenced pictures.

GCPs in shapefile format 1655 1
Started by Deleted User
Hello -
I created a point shapefile in ArcGIS that contains multiple GCPs. I'd like to import these points into the RCP orthorectification workflow. However the workflow can't read the shapefile. What format does the shapefile need to be in for it to be loaded

RapidEye 1B Azimuth and Zenith Angles for FLAASH 1897 2
Started by Deleted User
Please forgive my asking about the Azimuth and Zenith Angle parameters for FLAASH, as I know it has been covered here many time before. I have a specific question about RapidEye 1B.
Based upon the parameters that are listed in my accompanying metadata record, it would seem intuitive that I could calculate the Zenith Angle using the "spaceCraftViewAngle" which has a reasonable value of 3.067680e00 degrees. Therefore I believe the FLAASH Zenith Angle parameter would equal 180 - |3.06768...

Radiometric correction for surface reflectance and image fusion 1300 1
Started by Deleted User
I'm trying to fuse SPOT 5 PAN and XS images and having trouble with the radiometric correction. I was hoping to obtain at surface reflectance as the fused image will be used for vegetation analysis. I was able to calibrate and preform a FLAASH correction on the XS image but cannot follow the same procedure for the PAN image as FLAASH requires a multiband input. Is there another (fairly accurate) model for PAN atmospheric correction Or would it make sense to leave both images as radiance and pre...

How to unify spatial information and fill background values? 1420 2
Started by Deleted User
Hi, everyone, a TM mosaic image with 8496 samples and 7375 lines (30 m spatial resolution)could cover my whole area. Now I get a scene of TM, which is partly covered this area and contained some clouds. I masked out the clouds and subset this images, and it is samples and lines are 7208, 5564, respectively. I want to enlarge this cloud-free image to samples and lines of 8496 and 7375 (30 m spatial resolution), and fill the no-data area with -9999. I have dozen of image with clouds, I want to sub...

Landsat 8 in ENVI 4.x 2218 4
Started by Deleted User
Hi, I know I'm a little behind with my ENVI version (I don't see our institute upgrading for quite awhile).
I'm trying to generate a Land Surface Temp map using Band 10 (keeping it simple) in Landsat 8. I'm not exactly sure of the workflow, and seem to get a few different directions from different sources. If I understand right, I first need to convert to radiance, then TOA reflectance and possibly factor in emissivity using NDVI or some other classifciation method (I'm not sure if this last p...

VIIRS DNB Values (ENVI 5.1) 1421 1
Started by Deleted User
Hello,
I am trying to work with the day night band on VIIRS sensor. I can open and view the images with no problems and the image looks fine. However when I try to view the values they all appear as 0. I am assuming this is because the values of the pixels are in nanowatts (10^-9) and the values scale only shows number up to 10^-6. I have tried to use the band math option to multiply the values by 10^9 in order to try and normalize them but I end up with number on the order of 10^-6 for some rea...

When I use the Hyperion image with Radiometric Calibration Tool, with Flaash Setting, after completing calibration, a Pop up window appeared, and showing that
"The following spectral value in the ENVI header is not consistent with the number of bands: bbl
This value will be ignored."
When I reopen the calibrated image then it also shows same. what is the problem.
What value or File I have to use for "Radiance Scale Factor" at Flaash
Please help me
