TerrainPostsIntMinimum Class |
A collection of posts from a RasterTerrainProvider where each
post is stored as either an Int16 or an Int32.
The smallest data type that can represent the post data is chosen.

Methods| Name | Description | |
|---|---|---|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetFourPostHeights |
Gets the heights of four posts, specified by index.
(Overrides TerrainPostsGetFourPostHeights(Int32, Int32, Int32, Int32, Double, Double, Double, Double).) |
| GetFourSurroundingPosts |
Gets the indices of the four posts surrounding a given longitude and latitude point.
(Inherited from TerrainPosts.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetPostHeight |
Gets the height at a post.
(Overrides TerrainPostsGetPostHeight(Int32, Int32).) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IndexToLatitude |
Gets the latitude of the post at a specified index.
(Inherited from TerrainPosts.) |
| IndexToLongitude |
Gets the longitude of the post at a specified index.
(Inherited from TerrainPosts.) |
| LatitudeToIndex |
Gets the index of the post at or immediately to the south of the specified latitude.
(Inherited from TerrainPosts.) |
| LongitudeToIndex |
Gets the index of the post at or immediately to the west of the specified longitude.
(Inherited from TerrainPosts.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Remarks
This class is helpful for use with terrain providers where the possible range of heights is substantially
larger than the common range of heights. For example, the UsgsDigitalElevationModel terrain
format specifies that heights are 32-bit integers. However, for all practical purposes, the heights don't
exceed the bounds of a 16-bit integer. Using this type to store the posts for the UsgsDigitalElevationModel
terrain provider allows us to get the space and performance advantages of storing posts as 16-bit integers, while
still supporting the rare terrain file that actually requires 32-bit integers.
