This look pretty cool. I have like 30 rasters from the USGS that I need to combine. I am going to combine 4 rasters as a test but, I have the feeling that I should reclass the raster first. The rasters from USGS for the 1/9 arc second are like 350MB for each tile. I know that the mosaic tool can resample the cell size of the rasters but, the raster might process quicker if they are already resized. This whole process looks like its a job for Python.
I have more than 30 rastee, how you can use phyton to do this? I have been learning to use Google earth engine, and because the process are in the cloud you can do amazing things without use the process of your computer, what you want to do with python, is it the same?
@andressanchez175 haha, I dont remember. I made that comment six years ago when I was doing a lot of ArcGIS stuff. If I had to do Python stuff now, I would work with ChatGPT to help me write some code. It works pretty pretty well if you have a good foundation in Python.
Just potentially figured it out now (I know it's 2 years late but someone else might have the same problem going into the future). During the Mosaic step I left the ("Ignore Background Value" and "NoData Value") blank, when I ran the Mosaic it seemed to work.
Hi, I'm wondering why the TIF dataset that I added is showing RGB value instead of elevation value like in this video? does it mean that my dataset is not yet a raster? sorry for such a newbie question. Thx in advance, Geo tech.
Thank you very much but I have a question from which website you download the DEM data if you reply the website address to me on reply. I downloaded the data from a few websites but it has some problem with cell size like it doesn't have the exact cell size like 32 it give me cell size (0.00273773838) while I running my model. the cell size must be the exact number not decimal.
@@giliack7017 okay! Well, I realized I had chosen the wrong reference system ("sweref99" instead of "sweref99_tm", damn lookalikes..). But thank you for your answer!
@@trolltass8517 You we're welcome. Good for you. Your solution was simpler than mine. My reference system was correct, and the problema was a bug, detected by someone in a gis forum. I quite do not remember which one.

This is the video, I was looking for.
Thank you for this video. Your videos are helping many researchers including me. Many Thanks
Thank you for your useful video. It is so clear and clear.
You truly are the king of kings
Thank you so much! This video is a life saver!
tq..
Thank you! That was truly helpful!
THANK YOU BUDDY !!! YOU SAVED MY LOTS OF TIME!
for some reason the high and lowest value are 0 for me after the mosaic :(
Just potentially figured it out now (I know it's 2 years late but someone else might have the same problem going into the future). During the Mosaic step I left the ("Ignore Background Value" and "NoData Value") blank, when I ran the Mosaic it seemed to work.
Thank you so much. It's really helpful
Is it possible to apply several bands at a time to do mosaic? Thanks
How about directly using "mosaic to new raster"?
Save yourself a step and simply use the "Mosaic to New Raster" tool instead!
Sometimes "Mosaic to New Raster" tools gives error code for band selection for target raster
@@lifelezonsbyPartha bhai did yu get any solution]
Thank you very much , really helpful
Do you know why after I merge my images, the maximum value of the new raster almost doubles?

Thank you
Thank you very much
Ohhh my gosh thanks so much
It helps. Thank you.
Thanks. You saved me
you saved it, thank you
Followed your step but an error occurs while doing mosaic 😓 hw to fx it?
Thank u bb

What if the original image contains 4 bands
I also want to know, as mine also have 4 bands, and if I followed this video and keep on getting an error.
Try using "mosaic to new raster", then fill the number of band with 4
please upload more videos like this..
Thanks!
its better to understand

after this technique the merge file become full dark (black)
good video
Thanks
When I try to create a mosaic, a warning appears: ERROR999999
This tutorial is ridiculous
Hi! I'm having the same problem. Did you find any solution?
@@trolletingelmanaslund9100 I change for ArcMap 10.8 and in this version I could merge the raster files.
