Terrain or relief (also topographical relief) involves the vertical and horizontal dimensions of land surface. The term bathymetry is used to describe underwater relief, while hypsometry studies terrain relative to sea level. The Latin word terra (the root of terrain) means "earth."
In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns.
Relief (or local relief) refers specifically to the quantitative measurement of vertical elevation change in a landscape. It is the difference between maximum and minimum elevations within a given area, usually of limited extent.[5] A relief can be described qualitatively, such as a ".mw-parser-output .vanchor>:target.vanchor-textbackground-color:#b1d2fflow relief" or "high relief" plain or upland. The relief of a landscape can change with the size of the area over which it is measured, making the definition of the scale over which it is measured very important. Because it is related to the slope of surfaces within the area of interest and to the gradient of any streams present, the relief of a landscape is a useful metric in the study of the Earth's surface. Relief energy, which may be defined inter alia as "the maximum height range in a regular grid",[6] is essentially an indication of the ruggedness or relative height of the terrain.
Land surface parameters are quantitative measures of various morphometric properties of a surface. The most common examples are used to derive slope or aspect of a terrain or curvatures at each location. These measures can also be used to derive hydrological parameters that reflect flow/erosion processes. Climatic parameters are based on the modelling of solar radiation or air flow.
A digital elevation model (DEM) or digital surface model (DSM) is a 3D computer graphics representation of elevation data to represent terrain or overlaying objects, commonly of a planet, moon, or asteroid. A "global DEM" refers to a discrete global grid. DEMs are used often in geographic information systems (GIS), and are the most common basis for digitally produced relief maps. A digital terrain model (DTM) represents specifically the ground surface while DEM and DSM may represent tree top canopy or building roofs.
I narrowed down the location selection to see if I still get the terrain. If your colleague can get the terrain for the same location but you cannot, it clearly has something to do with your computer. Who did you buy the SketchUp license from? Directly from SketchUp or an authorized 3rd party reseller?
Above your terrain, create a single plane of geometry, the same size or a bit larger than the terrain.
Paint the plane with the texture.
Edit the texture transparency so you can see through it to the terrain below.
I am relatively new to SAR processing, and am working on processing a stack of S1A SLC IW images for basic classification on mountain glaciers. I have begun to incorporate calibrating to Beta0 and Terrain Flattening, as the terrain is quite complex. My processing flow thus far is:
The results show images that appear much more speckled than ignoring skipping Terrain Flattening altogether, and simply Terrain Correcting and applying radiometric normalization (everything else in the work flow remains the same). Anyone know why this might be?

Sigma0 Without Terrain Flattening
terrain flattening tries to correct the radiometric distortions caused by different local incidence angles.
That means, that originally areas facing the sensor are pictured brighter and the other ones darker. Terrain flattening then uses a DEM to re-calculate the actual radiometry based on the area illuminated per pixel.
If your DEM is bad, you could make it worse, theoretically - especially at ridges facing towards or away from the sensor. You can try the ALOS World DEM for a comparison. It also has 30 meters but was made from optical stereoscopy
The Georgia Department of Natural Resources has partnered with the Aimee Copeland Foundation to provide free, high mobility all-terrain track wheelchairs at 10 state parks, historic sites and a wildlife center. The initiative encourages those with mobility impairments to reconnect with nature, explore nature trails, go fishing and attend adaptive hunts. All-terrain track chairs are designed with safety in mind, giving Georgians who otherwise might not be able to navigate more difficult types of terrain the ability to hit the trails and easily navigate through mud, water, sand and snow. Qualifying park visitors can experience a sense of freedom that can be difficult to have in an everyday wheelchair. The chairs can be used for hiking, hunting, fishing and other outdoor education and recreational activities.
To help with the weekend crowd we run a dedicated lift so terrain park users can get as many runs as possible! We frequently change the layout of the 40+ features so that you have something new each time you come to ski or ride. On any day, you might find:
Slopestyle: Slopestyle is a winter sport in which athletes ski or snowboard down a course including a variety of obstacles including rails, jumps and other terrain park features. Slopestyle tricks fall mainly into four categories: spins, grinds, grabs and flips. Most tricks done in competition are a combination of these.
In an effort to improve the terrain park experience for our guests Boyne Resorts offers this terrain park etiquette and education program, better known as PEEPs. PEEPs gives you the opportunity to check out and read up on the latest information available regarding terrain park safety. We are proud to offer this one of a kind educational terrain park program.

I am trying to duplicate terrain for multiple different scenes and alter the terrain slightly, such as the grass and trees. However, when doing so, making one change to one terrain changes the terrain on another scene. I am aware of why this happens and have tried multiple different things (such as duplicating the terrain data itself) to get this to work but nothing has seemed to work so far. I am using Unity 5.1.1. Is there any way I can get across this? Doing so would save a lot of time in reconstructing the terrain. I am also aware that questions like this have been posted on here, but none of the solutions have worked unfortunately. Any help thus would be appreciated!
when you duplicate the terrain and the data file, you have to assign it to the copy in the editor. to do so, open the terrain copy in editor and change the inspector view to debug mode. there you can assign the copied data.
Terrain Parks provide lots of fun, but safety and proper use is important. Using common sense and being aware can help reduce the risks inherent with any sport. Specialized equipment such as helmets and wrist guards may help to reduce the incidence or severity of injury. For more information and Park Education go to: terrainparksafety.org or nsaa.org.
Freestyle Terrain may contain jumps, hits, ramps, banks, fun boxes, jibs, rails, half pipes, quarter pipes, snowcross, bump terrain, and other constructed or natural terrain features. PRIOR to using Freestyle Terrain, you are responsible for familiarizing yourself with Freestyle Terrain and obeying all instructions, warnings and signs. Freestyle skills require maintaining control on the ground, and in the air.
Freestyle terrain is provided for your enjoyment and offers adventure, challenge, and fun. However, freestyle terrain use, like all skiing and riding, exposes you to the risk of serious injury or even death. Prior to using freestyle terrain, it is your responsibility to familiarize yourself with all instructions and warnings and to follow Your Responsibility Code.
Hello, I just started using Gaea. I was following the tutorial that Gaea provides of their Hero Mountian. Towards the end when he started adding color and texture, my terrain flattened and I am not sure how to get it back to normal with all the textures still affecting it. Something does pop up when occasionally when I click on texture but it disappears before I can read anything. I'll provide pictures to show my issue.
All-terrain track wheelchairs are available for use at eight Louisiana State Parks. The all-terrain, electric-powered chairs are specially designed to be used on designated park trails not suitable for conventional wheelchairs.
Bear Creek is home to three diverse, exciting, and challenging terrain parks. Each terrain park is designed and built in-house by The Parks at Bear Creek. Park Rangers maintain the terrain parks throughout the winter season.
