Method Summary

Methods

Modifier and Type	Method and Description

void	setGeometry(double minLatitude, double minLongitude, double latitudeStep, double longitudeStep, int latitudeRows, int longitudeColumns) Set the tile global geometry.

Method Detail

setGeometry

void setGeometry(double minLatitude,
               double minLongitude,
               double latitudeStep,
               double longitudeStep,
               int latitudeRows,
               int longitudeColumns)
                 throws RuggedException

Set the tile global geometry.

Parameters:

minLatitude - minimum latitude

minLongitude - minimum longitude

latitudeStep - step in latitude (size of one raster element)

longitudeStep - step in longitude (size of one raster element)

latitudeRows - number of latitude rows

longitudeColumns - number of longitude columns

Throws:

RuggedException - if tile is empty (zero rows or columns)

setElevation

void setElevation(int latitudeIndex,
                int longitudeIndex,
                double elevation)
                  throws RuggedException

Set the elevation for one raster element.

BEWARE! The order of the indices follows geodetic conventions, i.e. the latitude is given first and longitude afterwards, so the first index specifies a row index with zero at South and max value at North, and the second index specifies a column index with zero at West and max value at East. This is not the same as some raster conventions (as our row index increases from South to North) and this is also not the same as Cartesian coordinates as our ordinate index appears before our abscissa index).

Parameters:

latitudeIndex - index of latitude (row index)

longitudeIndex - index of longitude (column index)

elevation - elevation (m)

Throws:

RuggedException - if indices are out of bound
