topic Quantifying post-NDVI pixel values in ArcGIS in Data Management Questions https://community.esri.com/t5/data-management-questions/quantifying-post-ndvi-pixel-values-in-arcgis/m-p/681689#M38659 <HTML><HEAD></HEAD><BODY><SPAN>Hi-</SPAN><BR /><BR /><SPAN>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?
