Using ENVI's band calculation tool, you can flexibly enhance vegetation, but there are many operating steps (calculating NDVI, band calculation, band combination, etc.), and it is not convenient to use. In order to improve work efficiency, this patch only needs one step. The final enhancement result is obtained, and 3 kinds of enhanced intensity and 2 kinds of output band combination modes are provided. At the same time, when synthesizing new bands, segmented enhancement is used to make the vegetation enhancement effect more natural. As shown in the following formula, b1 is NDVI, b2 is Nir, and b3 is Green. According to the scope of NDVI, enhancement is performed in segments.
First copy the envi_vegetation_enhance.sav patch to the following installation path (take ENVI 5.2, 4.8 as examples):
ENVI 5.2: C: \ Program Files \ Exelis \ ENVI52 \ extensions \
ENVI Classic: C: \ Program Files \ Exelis \ ENVI52 \ classic \ save_add \
ENVI 4.8: C: \ Program Files \ ITT \ IDL \ IDL80 \ products \ envi48 \ save_add \
Just restart ENVI.
Note: This SA file supports the minimum ENVI version 4.8. Earlier versions can compile the PRO file to SA by themselves.
