topic How to delete 0 data in ArcMap? in Spatial Statistics Questions https://community.esri.com/t5/spatial-statistics-questions/how-to-delete-0-data-in-arcmap/m-p/561017#M1790 <HTML><HEAD></HEAD><BODY><P>Recently I'm working on a project that needs me to calculate the LST of an image. I clipped the raster image by mask and there are many data with an invalid value (pixels outside the mask region) after calculating LST in ENVI software. How can I eliminate those data from the calculation process?&nbsp;Because I need to calculate the max and min as well as average LST value of the whole image, and the areas with the invalid value are just so disturbing.</P><P></P><P>Any ideas and suggestions about how to solve this problem?
