Field Detail

system

static final java.lang.String[] system

public final String[] system defines the ground planimetric reference system, data element 5 in the dem specification. 0=Geographic, 1=UTM, 2=State plane. Code 0 represents the geographic (latitude/longitude) system for 30-minute, 1-degree and Alaska DEM's. Code 1 represents the current use of the UTM coordinate system for 7.5-minute DEM's. (Pretty much all contemporary dems...)

Dem.get_planimetric_system()

units

static final java.lang.String[] units

public final String[] units containns the values "feet","meters","arc seconds". These are the horizontal units specified in the Dem specification. For example, if the horizontal unit is equal to 1, then the dem file horizontal unit is meters. units[1] is also equal to meters, which is useful for comparison.

See Also:

Dem.get_planimetric_unit()

vdatum

static final java.lang.String[] vdatum

public final String[] vdatum containts the values "mean sea level", "NGVD29", "NAVD88". These are various vertical datums that might be found in dem files. These are in the order of the dem specification, but 0 based. Thus if the vertical datum element in a dem (Element 26) is equal to 2, it is a NGVD29 file, and hdatam[1] (horizontal datum -1) equals NGVD29, which is useful for comparison.

See Also:

Dem.get_vertical_datum()

hdatum

static final java.lang.String[] hdatum

public final String[] hdatum contains the values "NAD27","WGS72","WGS84","NAD83", "OLD Hawaii","Puerto Rico","NAD83 provisional". These are various horizontal datums that might be found in dem files. These are in the order of the dem specification, but 0 based. Thus if the horizontal datum element in a dem (Element 27) is equal to 1, it is a NAD27 file, hdatam[0] (horizontal datum -1) equals NAD27, which is useful for comparison.
