For a grid coverage a sample dimension is a band. Sample values in a band may be organized in categories. This implementation is capable to differenciate <em>qualitative</em> and <em>quantitative</em> categories. For example an image of sea surface temperature (SST) could very well defines the following categories: <blockquote><pre> [0] : no data [1] : cloud [2] : land [10..210] : temperature to be converted into Celsius degrees through a linear equation </pre></blockquote> In this example, sample values in range defines a quantitative category, while all others categories are qualitative. The difference between those two kinds of category is that the <A HREF="../../../org/geotools/coverage/Category.html#getSampleToGeophysics()"><CODE>Category.getSampleToGeophysics()</CODE></A> method returns a non-null transform if and only if the category is quantitative. <p> While this class can be used with arbitrary coverage, the primary target for this implementation is grid coverage storing their sample values as integers. This explain the "" prefix in the class name.<P><P><DL><DT><B>Since:</B></DT> <DD>2.1</DD><DT><B>Author:</B></DT> <DD>Martin Desruisseaux</DD><DT><B>See Also:</B><DD><A HREF="../../../serialized-form.html#org.geotools.coverage.GridSampleDimension">Serialized Form</A><DT><B>Module:</B></DT><DD><CODE><B>module/coverage</B></CODE> (<A HREF="http://maven.geotools.fr/repository/org/geotools/gt2-coverage/"><CODE>gt2-coverage.jar</CODE></A>) (<A HREF="http://maven.geotools.fr/reports/coverage/index.html">Maven report</A>) (<A HREF="http://svn.geotools.org/geotools/tags/2.3.2/module/coverage/src/org/geotools/coverage/GridSampleDimension.java">SVN head</A>)</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> </CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/coverage/GridSampleDimension.html#GridSampleDimension()">GridSampleDimension</A></B>()</CODE><BR> <B>Deprecated.</B> <I>Use <A HREF="../../../org/geotools/coverage/GridSampleDimension.html#GridSampleDimension(java.lang.CharSequence)"><CODE>GridSampleDimension(CharSequence)</CODE></A> instead.</I></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> </CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/coverage/GridSampleDimension.html#GridSampleDimension(org.geotools.coverage.Category[], javax.units.Unit)">GridSampleDimension</A></B>(<A HREF="../../../org/geotools/coverage/Category.html" title="class in org.geotools.coverage">Category</A>[] categories, <A HREF="http://jsr-108.sourceforge.net/javadoc/javax/units/Unit.html" title="class or interface in javax.units">Unit</A> units)</CODE><BR> <B>Deprecated.</B> <I>Use <A HREF="../../../org/geotools/coverage/GridSampleDimension.html#GridSampleDimension(java.lang.CharSequence, org.geotools.coverage.Category[], javax.units.Unit)"><CODE>GridSampleDimension(CharSequence, Category[], Unit)</CODE></A> instead.</I></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> </CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/coverage/GridSampleDimension.html#GridSampleDimension(java.lang.CharSequence)">GridSampleDimension</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/CharSequence.html" title="class or interface in java.lang">CharSequence</A> description)</CODE><BR> Constructs a sample dimension with specified name and no category.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> </CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/coverage/GridSampleDimension.html#GridSampleDimension(java.lang.CharSequence[])">GridSampleDimension</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/CharSequence.html" title="class or interface in java.lang">CharSequence</A>[] categoriesNames)</CODE><BR> <B>Deprecated.</B> <I>Replaced by <A HREF="../../../org/geotools/coverage/GridSampleDimension.html#GridSampleDimension(java.lang.CharSequence, java.lang.CharSequence[])"><CODE>GridSampleDimension(CharSequence, CharSequence[])</CODE></A>.</I></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> </CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/coverage/GridSampleDimension.html#GridSampleDimension(java.lang.CharSequence[], java.awt.Color[])">GridSampleDimension</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/CharSequence.html" title="class or interface in java.lang">CharSequence</A>[] names, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/Color.html" title="class or interface in java.awt">Color</A>[] colors)</CODE><BR>⌨️ 快捷键说明
