Export DTM raster image for visualization

PIX4Dmapper

A two-part question here.

I created a DTM in my project because we want to overlay a heatmap of the site topography for a presentation. I adjusted the coloring of the DTM in the visualization tab of the mosaic editor with a color scheme and elevation range that works very well. Is there a way to export a new DTM with the color settings that are set in the visualization window?

I also am unable to even open the TIF to see the DTM in photoshop. When I open it, it’s just a black background with a white fill where the flight data should be. Is there a way to open this in photoshop, or another software where I can actually use that image file to create a good visual for a presentation?

Maybe it’s not possible, or maybe I’m just missing something obvious but if anyone has any experience with this, help would be greatly appreciated!

Hi jkpower,

You need to open the DTM in a GIS software like ArcGIS Pro or QGIS. These programs are designed to analyze, manipulate, and symbolize raster files. Photoshop is designed for photography, and will not display these files very well. I hope this helps.

I guess my confusion comes from the fact that I can open the orthomosaic just fine in photoshop, and haven’t had issues in the past with TIFs in photoshop. But understood if there’s some sort of metadata in the TIF that isn’t processed correctly in photoshop.

That leads back to my first question of can I actually change the color scheme within mapper and export that particular color gradient & elevations rather than the default one you get after the initial processing?

Mapper only has one color scheme. However, even if you could change the symbology of the DSM/DTM, it is not retained in the .tiff file. You need to use a GIS software to view the file in a different color scheme. QGIS is free, and it would allow you to change how it is displayed.
