![]() ![]() You can tweak the height of your landscape with the strength value. If you check the modifiers section, you’ll see that a displacement modifier has been added. You should now see some bumps on your map. Wait for some seconds for the program to fetch the data. To do that, head to the GIS addon again and navigate to web geodata > Get SRTM. Next, we need to add height detail to our plane to give it topographical detail. This automatically captures your map and assigns it as an image material to a plane. When you’re fully satisfied with your selection, hit the E button. Use the middle mouse button to position the map precisely. You can also navigate directly to your desired location by hitting G on your keyboard and typing the name of the place. Isn’t that incredible? Now you can use the mouse wheel to zoom in and out. You’ll be presented with a world map with which you can interact within Blender. We’ll use Google for the source and satellite as the layer. To begin, click the GIS feature and navigate to web geodata > basemaps.Ī small dialogue box will appear, asking you to select the source and layer. Our source of height data will be NASA’s Shuttle Radar Topography Mission ( SRTM) radar database. The height data will help us define how the ground rises or falls in relation to the coordinates of the base map. We’ll get our base maps from Google maps. Most base maps are drawn to scale to represent actual distances on the ground. In order to create a vibrant landscape, we need two things: the base map and height data.The base map is a digital photograph of the area you want to capture. The GIS feature should appear in your viewport Importing Base maps and Height Data Next, in Blender, navigate to Edit > Preferences > addons > install How to installīegin by downloading the Blender GIS Zip file from Github There are many more powerful functionalities built into the addon, so you might want to check it out yourself. With Blender GIS, you can also grab geodata directly from the internet, compute terrain mesh, and manage georeferencing information of your scene. Some compatible formats are raster image, geotiff DEM, Shapefile vector, and OpenStreetMap xml. The addon in question is called Blender GIS, and can be downloaded for free from github.īlender GIS allows you to import data files in most common GIS formats. Since Blender is not specially designed to handle GIS data, we will install a tailored addon. ![]() Common ones are Esri open data hub and Natural Earth data. For instance Openstreetmap (OSM) files are native to the Openstreetmap collaborative project which amasses various geo data, including streets, buildings, and water courses.Īpart from Opensteetmap, there are many other GIS data sources that offer free access to geospatial data sets. The GIS employs specific file formats depending on the particular type of data you’re dealing with. The reference data that we will use will be sourced from the GIS – a system for documenting geographically referenced information. For beginners, Blender is an open source 3D software that you can download for free from. In this article is an easy method for creating 3D landscapes in Blender using free geographical data from Google Maps and satellite imagery. All we need is the reference data (thus the name – georeferencing). That means we could create landscapes that mirror real terrain on the earth’s surface. Those sets of rules have to do with the use of bump, normal, and displacement maps, which by design, are meant to create the illusion of depth on the surface of a 3D mesh.Īlthough these maps can be randomly generated by the computer, they can also be based on predesigned or actual data. Here, the artist uses a set of rules and algorithms to generate bulges and dimples that make up common land features. The usual method of creating terrain is through procedural generation. This often involves laying out the topography and all the landforms. When building virtual worlds for video games and films, 3D artists have to create landscapes, at least in most cases. Thus, you could say the sky is the ceiling. In a typical outdoor environment, it represents the floor of the world. Mountains, hills, valleys, plains, rivers, seas these precious nuggets of nature define our unique human experiences.Īnd because they are everywhere, landscapes are part and parcel of digital art.Ī landscape forms a backdrop on which a digital artist presents a work of art. ![]()
