How to Change Projection Coordinate System of a Raster in ArcGIS

This tutorial shows you how to change projection coordinate system of a Raster in ArcGIS. Any analysis that uses remote sensing images must have the same coordinate/projection system for all raster datasets. It’s very crucial, otherwise the output raster will display an error message. Anyway, I hope you will find these tutorials useful.

Thank you for demostration

Welcome

if we have map with 2 zone UTM for example WGS_1984_UTM_Zone_48S & WGS_1984_UTM_Zone_49S &, which project coordinate system will used? Thanks

How to convert if my study area is whole country, India. It has 6 coordinate systems, please reply

Can you please tell the difference between project raster tool and define projection tool?

In ArcMap, the "Project Raster" tool and the "Define Projection" tool are both used for working with spatial data and managing coordinate systems. However, they serve different purposes: Project Raster Tool: The "Project Raster" tool is used to convert a raster dataset from one coordinate system to another. It allows you to reproject raster data to align with a different coordinate system or projection. Reprojection is necessary when you have raster datasets in different coordinate systems and need to overlay or analyze them together. This tool preserves the pixel values of the raster while transforming the spatial reference. Define Projection Tool: The "Define Projection" tool is used to assign or define the coordinate system and projection information to a raster dataset that does not have a defined projection. It does not actually change the spatial reference of the raster; instead, it updates the metadata of the dataset to reflect the correct coordinate system information. This tool is useful when you have a raster dataset with an unknown or incorrect projection and you want to ensure it is correctly interpreted and integrated with other spatial data. In summary, the key difference between the two tools is that the "Project Raster" tool changes the spatial reference of the raster dataset to align with a different coordinate system, while the "Define Projection" tool assigns or updates the metadata to reflect the correct coordinate system information without changing the actual spatial reference.

Can you make a video burn stream network into DEM

Why I can’t it😢
