<title>GrADS Command: set geotiff</title></head>
<body bgcolor="e0f0ff" text="#000000">
<h2><b>set geotiff</b></h2>
<p>
<code>set geotiff <-flt | -dbl> <i>fnameroot</i></code>
<p>
Sets the filename root and other characteristics for GeoTIFF output. </p>
<ul>
<code><i>fnameroot</i> </code>Output filename root -- GrADS will append ".tif" to the end <br>
(The default output file name is <code>gradsgeo.tif</code>)<br>
<code>-flt </code>Data will be written to file using floating-point precision (default)<br>
<code>-dbl </code>Data will be written to file using double precision<br>
</ul>
<p>
<h3>Usage Notes</h3>
<p>
This command is available in GrADS v2.0.a5 or later.
<p>This command is used in conjunction with the <code><a href="gradcomdsetgxout.html">set gxout geotiff</a> </code> command which sets the graphics output type; the <code><a href="gradcomddisplay.html">display</a></code> command will then create the output file instead of drawing a plot. The output data file will be in GeoTIFF format, which is a georeferenced raster image. The GeoTIFF output is a grid of data values, similar to the 'grfill' graphics output type, except the pixels (grid elements) in the image can be tied to a geographic location.
<p>The file <code><i>fnameroot</i>.tif</code> will be replaced if it exists.
<p>If the <code>-flt</code> or <code>-dbl</code> options are not given, the output will be written using floating-point precision. No compression algorithm is used when creating the GeoTIFF file.
<h3>Examples </h3>
<p><code>set geotiff my_name<br>
set gxout geotiff<br>
d my_var</code><br>
</p>
<p>Note: The GrADS expression <code>my_var</code> must be a 2-dimensional grid that varies in X and Y (longitude and latitude). </p>
