Quantifying post-NDVI pixel values in ArcGIS

[EmmaYoung]

Hi-

I'm working with high resolution imagery in ENVI, and so far I've masked my data and performed an NDVI analysis. Next, I'd like to quantify the number of pixels in a given value range, for example, all the pixels valued between -1 to -0.5, -0.5 to 0, 0 to 0.5, and 0.5 to 1 (NDVI only contains values from -1 to +1). Does anyone know how I might go about this using ArcGIS? Thanks!

You can run Reclassify using those break values.  The output raster attribute table will have a count field for each class.

Best,
Eric

Perfect, thanks!
