Coloring a hillshade as exactly same as ARCGISONLINE shaded relief map?

Can anyone tell me how to create exactly same hillshade effect with ESRI online hillshade Relief

OR the base map of the ESRI street maps.


Mapping Center Answer:

The first one is in a style you can download from a blog entry we did some months ago on choosing color ramps for hillshades.  It's the "warm gray" example.

But, that said, getting an exact match with a different hillshade raster is nearly impossible.  The issue is how the values, ranging 0-255, are distributed in each hillshade dataset--and every hillshade dataset is different.  To get a closer match, you can use the histogram tool to interactively adjust how the colors are applied across the distribution of values.

You can combine the "warm gray" colors described above with the Swiss hillshade effect to get a "softer looking" hillshade. The Swiss hillshade tool is available in the Hillshade toolbox. You can download this from Mapping Center on the ArcGIS Resources page under the Tools/Models/Scripts tab.

Once you've used the Swiss hillshade tool, change the color ramp for the Filtered Hillshade to the warm gray color, and drop the transparency to about 10%.

To change the color ramp, you can either click the color ramp in the Table of Contents or you can right click the raster layer, click Properties, click the Symbology tab, and click the color ramp in this dialog.

If you know the name of the color ramp, you can find it more easily by searching by name rather than searching using the graphic view. To search by name, right click the color ramp in the dialog box (either directly from the Table of Contents or from the raster layer properties), and click Graphic to toggle that view off. Now you can scroll through the color ramps to search by name.

Note that the order of the color ramps from the Table of Contents is the same as the order of styles shown in Style Manager. The order of names in the Layer Properties dialog is alphabetical, so it is sometimes easier to search through the Layer Properties dialog.

If this is too light for you, you can easily make it a little darker. Just click the color ramp for the Filtered Hillshade in the Table of Contents, right click the color ramp in the area where you select it, then click Properties. Click the drop down for Color 1, and click More Colors. Here, make sure the color model (in the upper right) is set to HSV (hue, saturation, value). Then slide the value arrow over to the left until the color example at the bottom left is the color you want. Click OK until you get back to the point where you can right click the color ramp again.

Now click Save to Style... if you want to save this newly defined color ramp. Give it a name. You will be able to find this color in your personal style in the color ramps folder when you look for it using Style Manager.

What Hillshade and Azimuth do you use when generating the relief?

I use the default altitude of 45 degrees and the default azimuth of 315 degrees. I keep the Z factor at the default value of 1. I do not check the option to model shadows.
