By doing so, you are changing the source data. False - Answer- You have a mosaic dataset from your client. You want to use the mosaic dataset with other spatial data on the web. When you import the data into ArcMap, you realize that the mosaic dataset is in NAD 1983 HARN UTM Zone 5N. What would you do if you wanted to change the projection to WGS 1984 Web Mercator Auxiliary?
