Function members are as follows:
Return Type | Function Name | Documentation |
---|---|---|
int32 | DumpElevationInfo | Populates a <Float64Array> object with meta-data about the elevation data set this object represents. The output values are as follows: minimum longitude, minimum latitude, maximum longitude, maximum latitude, minimum elevation, maximum elevation, pixel units x, and pixel units Y. |
int32 | DumpRasterInfo | Populates an <Int32Array> object with meta-data about the raster data set this object represents. The output values are as follows: total raster dimensions in x pixels, total raster dimensions in y pixels, chunk dimension in x pixels, chunk dimension in y pixels, the number of chunks on x, the number of chunks on y, size of each block pixel in bytes, block item count in pixel elements, and the block offset in bytes. |
int32 | GetChunkCountX | Returns the chunk count along x. This is the number of individual chunks along the X axis of which the GEOTIFF is composed. |
int32 | GetChunkCountY | Returns the chunk count along y. This is the number of individual chunks along the Y axis of which the GEOTIFF is composed. |
int32 | GetChunkDimX | Returns the chunk dimension along x in pixels. |
int32 | GetChunkDimY | Returns the chunk dimension along y in pixels. |
int32 | GetChunkItemCount | Returns the total number of pixel elements in each chunk. |
int32 | GetChunkItemSize | Returns the atomic size of the element of each chunk in bytes. For example: 4 if the GEOTIFF stores 32-bit floating point elevation data. |
int32 | GetChunkOffsetInBytes | Returns the offset of the chunk in bytes. |
double | GetElevationRange | Returns maximum elevation - minimum elevation (which is in meters). |
double | GetMaxElevation | Returns the maximum elevation in meters. |
double | GetMaxLatitude | Returns the maximum latitude. Typically this value is in degrees such as 45.25. This value can be negative. |
double | GetMaxLongitude | Returns the maximum longitude. Typically this value is in degrees such as 122.5. This value can be negative. |
double | GetMinElevation | Returns the minimum elevation in meters. |
double | GetMinLatitude | Returns the minimum latitude. Typically this value is in degrees such as 45.25. This value can be negative. |
double | GetMinLongitude | Returns the minimum longitude. Typically this value is in degrees such as 122.5. This value can be negative. |
int32 | GetRasterSizeX | Returns the value in pixels of the total raster size on x. This is the sum of the dimensions of each chunk along x. |
int32 | GetRasterSizeY | Returns the value in pixels of the total raster size on y. This is the sum of the dimensions of each chunk along y. |
double | GetSpacingX | Returns the distance in meters between elevation points along x. For example a 1/3 arc-second GEOTIFF returns roughly 10 for 10 meter spacing. |
double | GetSpacingY | Returns the distance in meters between elevation points along y. For example a 1/3 arc-second GEOTIFF returns roughly 10 for 10 meter spacing. |
