Reclassify Issue

MarieJ — Thu, 14 Apr 2022 23:54:04 GMT

I'm trying to reclassify the raster layers but it gives an error saying "The raster does not have statistics and histogram and the gp analysis extent is not defined."

How do I fix this?

Thanks

Thanks for your response.

Kind of new to Arcgis Pro - how do I open up to calculate statistics?

Thanks

Open your Geoprocessing pane, by clicking the Analysis tab, then Tools. Expand the Data Management toolbox. Expand Raster. Expand Raster Properties. Alternatively, just type in Calculate Statistics into the search box at the top where it says Find Tools.

Hi,

I tried to reclassify this raster from MODIS imagery [ATTACH=CONFIG]14798[/ATTACH], but the result looked like this [ATTACH=CONFIG]14799[/ATTACH].
This is the mapping [ATTACH=CONFIG]14800[/ATTACH]. It is pretty straightforward, 0 should become 1, all other values should become 0. Reclassify tool in spatial analyst both classified and projected falsely the image. Do you have any idea? MODIS imagery is in sinusoidal projection. I installed the Service Pack 4.
