Interesting video, but would it be okay if the final mosaic had a maximum value of 65, 535? I have combined 11 maps of the same type of 12.5, and the maximum value does not exceed 6000. I have generated several MOSAICS several times and I get the same result. HELP ;-;

Thanks brother for your effort. I have 720 DEM to mosaic, hope it will be working.

Thanks for sharing this. Why do you have negative values (minimum= -255) in the first raster in the TOC. When do we have negative raster values? And why the data in the mosaic raster ranges from 0 to 255? what happened to the negative values?

Hi.. I am having problems using ArcGIS Hydrology tools once I combine a number of DEMs into a Mosaic. By that I mean I cannot conduct the fill tool from the hydrology toolbox. Please advise.

i did mosaic and tried to fill the DEM. it is not working .. any idea why?
i am able to fill Individual DEM . problem with only after the mosaic!

I tried to do so, but the output raster cell values range from 0 to 255, while of the origin raster has values less than 0 and more than 255, how to fix it?

[omniuss]

it was signed 16 bit and you did not change it but left it at unsigned 8 bit. Why?

[arundhathyrnair]

When I give mosaic to new raster,
It shows an error in executing function.. Can u plz help

[moo_moon]

what version of arc are you utilizing sir?

[vinayrao]

You didn't change it to 16bit signed
