comment ArcGIS dynamic layers performance with many features to display
The problem with scale dependency is we still want to give the user the symbology of data as they zoom in/out vs just turning off completely as they zoom out. It would definitely be fine if the symbology was greatly generalized as they zoom out but don't know a way of doing that. Yes, SDE is being used. So if we used SHP instead of SDE as the workspace type we may get better performance? File gdb likely better as well?

comment ArcGIS dynamic layers performance with many features to display
John, I should have been more clear but were not using a feature service at all here, only the dynamic map service. It's the dynamic map service that is taking several seconds to render when the extent is changed. I guess due to so much dense data it's causing the image from the server to take that long I guess? Does that sound right, more point data the dynamic map service is created from causes the render performance to decrease a great deal?

Thanks John. So you feel that the Dynamic Map service should have no problem displaying over 10,000 features within an extent as the user pans the map and not tie up the browser UI?

comment ArcMap Change Values Greater than Standard Deviation of Mean to Zero
Thanks radouxju, this works but it's still not ideal since I have to manually type in the std and mean. Seems like there should be a function I could use to calculate the mean and std vs. manually typing them. If you or someone here can show how that can be done, I will mark that as the answer. Thanks again for getting me most the way there.

comment Rating Randomness of Electromagnetic Conductivity (EC) Data Collected?
It's a little tough to know precisely what to consider pretty random data. I seem to be getting values less than 0.50 for what looks visually random, and values above 0.70 where the data looks more clustered. I'm always getting p-values of 0.0000 and very high z-values of often over 20. Thanks for directing me to this.

comment Rating Randomness of Electromagnetic Conductivity (EC) Data Collected?
Andrew, basically how random the data is. If values have large swings over a short distance, I would consider that highly random. If the values are much more gradual even over longer distances (points further from each other) then I would consider the data not random at all. Highly random data will tell us it's most likely bad data and not usable. I don't care to know whether the randomness is spatially explainable.
