DEM not reclassifying properly

Hi there! I'm using the latest version of ArcGIS Pro. I'm trying to reclassify a DEM (in meters). I set the processor up fine in the model maker as seen in the attached image. I run the model and receive no errors. However, the resulting image isn't right. The image has been "reclassified" into several groups that I didn't choose and the image is completely blue. I've tried to redo the process several times, and I've calculated stats on the DEM. I reclassified a few other rasters in this project and had no problem. Does anyone know what could be causing this problem?

Thanks!

reclassification is separate from symbology ,... what classification scheme did you use for the symbology for the layer?

The symbology in the left panel was made automatically. I didn't adjust that part in any way. I only did the inputs for the reclassify tool

then use a manual classification scheme to match your reclassification to get the visual that represents the reclassification.

Minna,

 

You've assigned the same value to all but one of your classes. That's probably not what you wanted to do.

You can use class-based symbology on your *input* DEM raster layer, and then the reclassify tool will use that classification and assign sequential output class values by default.
