Height map

This is an elevation data browser, which "auto-exposes" the display so that the highest and lowest visible elevations are white and black. The result is a grayscale heightmap, suitable for use as a displacement map in 3D applications. Here's a blog post about this toolwith more explanations and examples! Usage: Uncheck "auto-expose" to set min and max height levels manually.

Click "export" to open the current view as an image in a new tab - then "Save As" to save the image to disk. You may need to right-click the image to do this.

Import the resulting image as a displacement map in a 3D application to generate a 3D model of the terrain. Here's a tutorial for doing this in Blender. The "z:x scale factor" describes how "high" the current view is, on the z-axis, in terms of how wide the current view is on the x-axis.

Multiplying this scale factor by the width of a 3D mesh in units x will tell you how high in units z your mesh should be after displacement in order to be true-scale. Press the 'h' key to toggle interface visibility. Terrain data is coming from Mapzen 's global terrain tiles. Check out the code or fork this project on Github!

Tangram Heightmapper This is an elevation data browser, which "auto-exposes" the display so that the highest and lowest visible elevations are white and black.This tool can be used to find an estimate for the elevation of a point on the earth.

Estimate Elevation. How to export elevation data of any point to other format from this map By Keeol Sam on 3rd October But Can I find the highest elevation of an area? By thibaut on 26th September Tried this, no matter where you click it says "Elevation On 18th September Thanks, user friendly and did not waste a moment of my time.

By Ralph Johansen on 13th September Can I get a list of elevations from an input file with a list of lon and lat?

I would recommend that you start over from scratch. It would be nice to know where the data for this tool comes from On 6th July I've used this for a while and it was pretty accurate but the discrepancies in height are now substantial.

Maps you can make use of Instructions To use the elevation finder tool: Zoom and pan the map to find the desired location Click on the map to place a marker You will then see the estimated elevation displayed below the map.

Click again to place further markers and find the elevation Other Notes: You can find the elevation of any old marker by hovering over the marker with your mouse. Found the 'clear,' is down, below.

By Ralph Johansen on 13th September Can I get a list of elevations from an input file with a list of lon and lat?Included in the download are the highest possible resolutions of the chosen texture satellite, street and an 8 bit grayscale heightmap, both as PNG file. With this set its possible to create and edit your own 3D maps in the common 3D programs e.

You can also use these high-res images in the Embed 3D Map set to replace the low-res versions.

The loading time will increase afterwards, but the quality and details of the 3D map will appear much better. The size of the download image depends on the resolution of the used screen. To get the largest possible size, we recommend to use to switch to full screen view when selecting the map section. Depending on the screen resolution the heightmap and the respective texture can reach a size of 4.

The resolution of the 3D map preview is considerably lower max. Texture and heightmap will be exported in the highest possible resolution. Note : The resolution of the maps depends on the map provider. Satellite maps are currently available up to zoom level 13z, respectively up to 18z for the US and Europe.

Street maps are available up to 18z and Top maps up to 17z. We have no influence on the quality of these maps. Forgot your password? Lost your password?

Elevation, or geometric height, is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface.

Assumed illumination is from the west; shading is computed as a function of the east-west slope of the surface with a nonlinear exaggeration favoring low-relief areas. The resolution of the gridded data varies from true 2-minute for the Atlantic, Pacific, and Indian Ocean floors and all land masses to 5 minutes for the Arctic Ocean floor.

Less commonly, elevation is measured using the center of the Earth as the reference point. Everest or Chimborazo is at the higher elevation,[citation needed] as the Chimborazo summit is further from the Earth's center, while the Mt.

Everest summit is higher above mean sea level. Worldwide Elevation Map Finder. Search by Address. COM In computer graphicsa heightmap or heightfield is a raster image used mainly as Discrete Global Grid in secondary elevation modeling.

Each pixel store values, such as surface elevation data, for display in 3D computer graphics. A heightmap can be used in bump mapping to calculate where this 3D data would create shadow in a material, in displacement mapping to displace the actual geometric position of points over the textured surface, or for terrain where the heightmap is converted into a 3D mesh.

A heightmap contains one channel interpreted as a distance of displacement or "height" from the "floor" of a surface and sometimes visualized as luma of a grayscale image, with black representing minimum height and white representing maximum height. Heightmaps can be stored by themselves in existing grayscale image formats, with or without specialized metadataor in specialized file formats such as Daylon LevellerGenesisIV and Terragen documents. One may also exploit the use of individual color channels to increase detail.

For example, a standard RGB 8-bit image can only show values of grey and hence only heights.

This technique is especially useful where height varies slightly over a large area. Using only grey values, because the heights must be mapped to only values, the rendered terrain appears flat, with "steps" in certain places.

Heightmaps are commonly used in geographic information systemswhere they are called digital elevation models. Heightmaps can be created by hand with a classical paint program or a special terrain editor. These editors visualize the terrain in 3D and allow the user to modify the surface.

Normally there are tools to raise, lower, smooth or erode the terrain. Another way to create a terrain is to use a terrain generation algorithm. This can be for example a 2D Simplex noise function [1] or by Diffusion-limited aggregation.

Heightmaps are widely used in terrain rendering software and modern video games. Heightmaps are an ideal way to store digital terrain elevations; compared to a regular polygonal mesh, they require substantially less memory for a given level of detail. Most modern 3D computer modelling programs are capable of using data from heightmaps in the form of bumpnormalor displacement maps to quickly and precisely create complex terrain and other surfaces.

In the earliest games using software rendering, the elements often represented heights of columns of voxels rendered with ray casting. In most newer games, the elements represent the height coordinate of polygons in a mesh. From Wikipedia, the free encyclopedia.
