<xsd:documentation>WITSML Location Component Schema
This is a location that is expressed in terms of 2D coordinates.
In order that the location be understood, the coordinate reference system (CRS)
must be known.</xsd:documentation>
<xsd:documentation>A pointer to the wellCRS that defines the CRS for the coordinates.
While optional, it is strongly recommended that this be specified.</xsd:documentation>
<xsd:documentation>The survey location is given by a pair of tagged values.
The pairs may be:
(1) latitude/longitude,
(2) easting/northing,
(3) westing/southing,
(4) projectedX/projectedY, or
(5) localX/localY.
The appropriate pair must be chosen for the data.</xsd:documentation>
<xsd:documentation>The projected coordinate with east being positive.
This is the most common type of projected coordinates.
UTM coordinates are expressed in Easting and Northing.</xsd:documentation>
<xsd:documentation>The projected coordinate with north being positive.
This is the most common type of projected coordinates.
UTM coordinates are expressed in Easting and Northing.</xsd:documentation>
<xsd:documentation>The projected coordinate with west being positive.
The positive directions are reversed from the usual Easting and Northing values.
These values are generally located in the southern hemisphere,
most notably in South Africa and Australia.</xsd:documentation>
<xsd:documentation>The projected coordinate with south being positive.
The positive directions are reversed from the usual Easting and Northing values.
These values are generally located in the southern hemisphere,
most notably in South Africa and Australia.</xsd:documentation>
<xsd:documentation>The projected X coordinate with the positive direction unknown.
ProjectedX and ProjectedY are used when it is not
known what the meaning of the coordinates is. If the meaning is known,
the Easting/Northing or Westing/Southing should be used. Use of this pair
implies a lack of knowledge on the part of the sender.</xsd:documentation>
<xsd:documentation>The projected Y coordinate with the positive direction unknown.
ProjectedX and ProjectedY are used when it is not
known what the meaning of the coordinates is. If the meaning is known,
the Easting/Northing or Westing/Southing should be used. Use of this pair
implies a lack of knowledge on the part of the sender.</xsd:documentation>
<xsd:documentation>Flag indicating (if "true" or "1") that this pair of values was
the original data given for the location. If the pair of values was
calculated from an original pair of values, this flag should be "false" (or "0"),
or not present.</xsd:documentation>
<xsd:documentation>A Comment, generally given to help the reader
interpret the coordinates if the CRS and the chosen pair do not make them clear.</xsd:documentation>
