Using Image Analysis Functions to Display Layer Tints on Hillshades

andreamilan — Sun, 30 Apr 2017 11:30:05 GMT

Hello to everyone, i'm trying to apply this method Using Image Analysis Functions to Display Layer Tints on Hillshades | ArcWatch

to create an image that retains the original colors and details Using Image Analysis Functions to Display Layer Tints on Hillshades avoid a washed-out image with less detail. ( When the hypsometric tint is displayed transparently over the hillshade, the result is a washed-out version of the hypsometric tint and a less detailed version of the hillshade).

I have the layer with the applied ramp color, as in Figure 1 attached and the file in gray scale (fig2).

At step one,To treat the layer-tinted DEM I follow step by step instructions as follows:In the Export Raster Data dialog box, check Use Renderer and check Force RGB. Choose a location and file name, then click Save Choose to add the exported data to the map as a layer. The three-band RGB image will be added to the table of contents.

But the result is somewhat bizarre (fig3). Can you tell me why?

When I try to open the link to the image I get a message about an unsafe site. In GeoNet you can attach images or even better, simply copy the content of an image in the thread. Please avoid using external sites.

I normally use mosaic datasets for my DEM/DSM data and apply raster chain functions for easy visualization. See example here: https://community.esri.com/people/xander_bakker/blog/2016/07/18/using-mosaic-datasets-and-raster-chain-functions-to-analyze-interference-of-trees-on-an-overhead-power-line

It provides very fast display and visualize different derived products on the fly

thank you very much, I will also test your method, while attaching the images you could not see.

edit:

I created a mosaic dataset in my database and then I added the two raster layers to this mosaic dataset.

Now what should I do to visualize them? Processing template tab is empty e and mosaic dataset layer is displayed on screen as White.Thanks for your patience!

In my blog post: https://community.esri.com/people/xander_bakker/blog/2016/07/18/using-mosaic-datasets-and-raster-chain-functions-to-analyze-interference-of-trees-on-an-overhead-power-line there are a number of tools you should use:

Create Mosaic Dataset
Add Rasters To Mosaic Dataset
Build Overviews

After that the mosaic dataset should display normally. To implement the Raster Chain functions I recommend you to use the step described in Editing function chains in a mosaic dataset—Help | ArcGIS Desktop
