 Script to expedite preparing DEM's for Blender.
 
 As described in Daniel Huffman's [Creating Shaded Relief in Blender](https://somethingaboutmaps.wordpress.com/2017/11/16/creating-shaded-relief-in-blender/), significant work is necessary to find and prepare elevation data prior to rendering it in Blender. This work often includes mosaicing, reprojecting, clipping, resampling, rescaling, and translating DEM's(digital elevation models). While some of these steps require decisions specific to the project, many are repetitive. This repo contains a bash script which utilizes open source command line tools to expedite this work.

 By default, the script will mosaic(if there are multiple dems), reproject to your target projection, clip to your bounding box, and output a TIF with 16-bit unsigned integer values, scaled from 0 to 65,535. The script *does not* resample the DEM, instead retaining the full resolution of the input data. If I want to quickly resample my elevation data, I just pull the output into photoshop and make sure to resize with resampling set to cubic or bilinear. Here's a couple good resources for more on generalizing elevation data for hillshading:
