Field Detail

isDataOnly

public boolean isDataOnly

Flag to say if this record only contains elevation values or if it is the header record for this column. If this is data only, then none of the other values will be set, except the elevation points.

rowNumber

public int rowNumber

The row ID that this record belongs to (element 1). Starts at 1.

columnNumber

public int columnNumber

The column ID of DEM profile stored in this record (element 1). Starts at 1.

numRows

public int numRows

The number of rows covered by this record (element 2).

numColumns

public int numColumns

The number of columns covered by this record (element 2).

firstPositionX

public double firstPositionX

The X coord of the ground planimetric coordinates of the first elevation of this profile (element 3).

firstPositionY

public double firstPositionY

The Y coord of the ground planimetric coordinates of the first elevation of this profile (element 3).

localElevationDatum

public double localElevationDatum

Elevation of the local datum for the profile (element 4). The values are in the units of measure given by element 9 of the Type A record in this file.

minElevation

public double minElevation

Minimum elevation of this profile (element 5). The values are in the units of measure given by element 9 in logical record type A and are the algebraic result of the method outlined in element 6 of this record.

maxElevation

public double maxElevation

Maximum elevation of this profile (element 5). The values are in the units of measure given by element 9 in logical record type A and are the algebraic result of the method outlined in element 6 of this record.

elevations

public int[] elevations

The elevation values stored in this record (element 6). Elevations are expressed in the units of resolution from element 15 of record type A. A value in this array would be multiplied by the "z" spatial resolution (element 15, record type A) "and added to the " elevation oflocal datum for the profile (element 4 of this record) to obtain the elevation for the point.
