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? figure 1: figure2: figure3: ... View more

Hello, can you help me? I’m using terrain tool v1.1,If I run terrain mapping-> Swiss Hillshade I always get this error: (I use Arcmap 10.4.1) Executing: SwissHillshade cervinia.asc C:\Users\utente1\Documents\ArcGIS\swiss Swiss123 1 Start Time: Sat Apr 29 19:19:58 2017 Running script SwissHillshade… Failed script SwissHillshade… Traceback (most recent call last): File “C:\Users\utente1\Documents\ArcGIS\TerrainTools_v1_1\Scripts\SwissHillshade.py”, line 107, in swissHillshade(*args) File “C:\Users\utente1\Documents\ArcGIS\TerrainTools_v1_1\Scripts\SwissHillshade.py”, line 89, in swissHillshade outHillshade.save(outS) RuntimeError: ERROR 010240: Could not save raster dataset to C:\Users\utente1\Documents\ArcGIS\swiss\Swiss123_filter with output format GRID.

Hello to all, I found it very interesting this paper : http://cartography.oregonstate.edu/pdf/2006_JennyHurni_SwissStyleShading.pdf the same is reported here Cartography and Geovisualization Group, Oregon State University the results that they have achieved based on colour reference points and a look-up table is what I’ve always tried to get but I read that this process has been Implemented in a application prototype and I do not find this application in any software. I tried   with Terrain Tools for arcgis 10.3  , in documentation  I read that “Tools Swiss Hillshade” guilds and then combines several hillshades to give a yellow-blue Resulting Swiss hillshade effect “,it would seem a solution  but what I get is just one Swiss_Filtered grayscale and one Swiss_Hillshade grayscale, no blue yellow hue. You know tell me where I’m wrong? I would like to get a final result like this: http://cartography.oregonstate.edu/TerrainShadingAndColoring_files/stacks_image_1220.jpg but perhaps also because of my very simple English very simple, I can not find online articles, books or instructions that describe how to reproduce this effect digitally. I will be very grateful if you could give me some guidance thanks Andrea ... View more

Hello everyone,I would like to export the Hillshade from Arcmap maintaining the largest range of grayscale values and detail to have more flexibility in Photoshop. I found a video tutorial that explains how to do this,of which I put below link , but i don't understand why i get different results. I should export four raster , they are calculated from a DTM base5 Tiff 32 float , they will serve me for a topographic map to 25000 in photoshop (130x170cm 600 or 1200dpi ,I don't know yet ,this is the mo first project  and I will make the proofs ). The raster in the Table of Content of Arcmap that I have tried to export are the following: MDOW Hillshade Model ( calculated with Hillshade Tools 3.3) Aerial_Perspective (calculated with Hillshade Tools 3.3) Filtered_Hillshade (calculated with Hillshade Tools 3.3) HillSha_dtm ( calculated with Hillshade(spatial Analyst Tool) I tried with two export method. First method: File ==> Export Map, I can export it to the resolution that I want, but using this method I can not export to a depth greater than 8 bits . Second method: directly in Table Ff Contents , right-click on that I want to export raster ==> data ==> export data, and I choose tif without putting the check on render. But even then I do not have the option of choosing 16 bit because in my case this hillshade are all 8-bit originally : "MDOW Hillshade Model" in 8-bit ", " Filtered_Hshd_Clip "8-bit and HillSha_dtm is 8-bit , "HillSha_dtm" is 8 bit, only" Aerial_Persp_Clip "is 16 bits. Also I have another  problem with this second method : all tiff exported are in 72dpi resolution (3700x5500) insufficient ,I assume, for printing 130x170 cm map. Of course all these rastere arise from the same DTM 32bit float . As in the video hillshade is actually 16 bit, I imagine that this is possible but I do not know how. Thanks, Andre video tutorial that I have found; ... View more
