(If using a localised projection/CRS, click 'proj' and use those units instead) Roughly in the center of it, and round the less significant digits off. Decide on a scene origin that makes sense for your project. Click 'Geo' and enter the longitude and latitude you want to be the origin point of your project.WGS84 is probably the correct choice for most projects, unless you have access to GIS data from an area with it's own map projection and co-ordinate system, ie Antarctica uses EPSG:3031. Some features may be unavailable on Windows without GDAL. Note: installing GDAL into the Python environment packaged with Blender on Windows is beyond the scope of this tutorial, I found using BlenderGIS on Linux to be easier because it uses the system Python environment. (assuming your blender version is 2.79 on Windows). To install the plugin download the latest release and extract the zip's contents into: %userprofile%\AppData\Roaming\Blender Foundation\Blender\2.79\scripts\addons\ Merging and extracting the geo-rasters used here is a different subject so I might make a short tutorial on QGIS also. This tutorial will cover importing (GeoTIFF) LiDAR DEM/DSM products, and satellite terrain and aerial photos directly into blender, while accurately preserving the scale and units. This plugin is useful for track building because it enables scene geo-referencing using WGS84 or other co-ordinate reference systems (CRS), importing OpenStreetMap data, and importing geo-referenced rasters containing ortho-photography, or digital elevation/terrain and surface models. BlenderGIS is a blender plugin designed to bridge the gap between Blender and geographic data.
