Class BilTile

java.lang.Object
hec.map.tms.datasource.tile.bil.BilTile
All Implemented Interfaces:
Tile
public class BilTile extends Object implements Tile
This class represents one tile in a TMS. A TMS file can be made up of many levels and each level has many tiles. A tile is one unit of data in a grid. Multiple tiles "patch" together to make a quilt

This tile reads data in BIL format From ESRI - http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=BIL,_BIP,_and_BSQ_raster_files

    • getValues

      public float[] getValues(double[] x, double[] y, int numPoints)
      returns a double array of values that are located at points x,y. Values in the array are in the same order as the input x,y arrays. the x and y values are assumed to be in the same coordinate space as the data. I.E. the x/y values are offsets from the UL and UR and which is assumed to be (0,0)
