Reclassify issue

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.

Hi,
I have downloaded the data and tested this issue. The issue seems to be specific to your TIFF image. Here's what you could do to fix it.
- Convert your source TIFF image to a new TIFF by exporting it then run the reclassify tool on the exported image. or,
- Use the original source raster and save the reclassified raster as an IMG or FGDB raster.
Hope this helps!

Hi vattarai,
I will give you an update. I guess this issue is associated with the ArcGIS SP4. My ArcGIS 10 is running with SP4. My friend hasn't installed any SP4 yet. She did the calculation on ArcGIS 10 without SP4 and she didn't come across this problem. However, I did the calculation on ArcGIS 10 with SP4 and I experienced this problem. Would you try this on ArcGIS 10 with SP4 and without SP4?
