I guess I am dense, but restating the problem is not a solution. Referring to esri documentation about dates is also not a solution. ArcGIS has dropped the ball on this. I have date-time in a CSV file. when converted to a shapefile the time is lost. I have over 375,000 records, so retyping anything is not an option. turns out too that converting my CSV file date-time column to text does not help either because arcMap sees that text column and identifies it as date and drops the time anyway. I cannot see a solution. Why would anyone need 375,000+ records? ships crossing an ocean, or airplanes flying over a nation for two weeks are two reasons.

Is it possible to use my reprojection (with a different central meridian) of an ESRI online map on a story map that would be hosted by ESRI? In other words, I take the online ESRI map, give it another central meridian so that the entire Pacific Ocean shows without a break down the middle, then give it back to ESRI to include in a story map. Can I do that? Paul Jameson

Thank you for setting me on the right track. The re-sampling tool did improve the appearance. I tried many different combinations between technique and resolution. However, in the same category was also the Aggregate tool. I understand how it works and assumed it would not be as good. But I tried aggregate nevertheless and the appearance got even better. The test case was Australia and the best setting ended up being: aggregate - mean - cell factor = 8. Now all the mountains and valleys are clearly visible and all the detailed relief in more level areas appear to be smoothed out somewhat. I am not looking for precision but rather aesthetics. The viewers will be non-gis people on the web.

I have a question. I have altitude rasters that show too much data. In a small scale map (Pacific Rim countries), i would like to show the mountains and valleys but not every little bump on the surface of the earth, or on the bottom of the ocean. With that much detail when you are at a scale of the Pacific Ocean, it's too busy. The goal is to show the major mountain ranges and valleys. How do I go about thinning out the data. Do I have to convert it first to point data? And if so then what? Paul Jameson
