<DIV>The JPGW file mentioned by Simon is usually called 'world file'. Detailed description here:</DIV>
<DIV> </DIV>
<DIV><A href="http://en.wikipedia.org/wiki/World_file">http://en.wikipedia.org/wiki/World_file</A></DIV>
<DIV> </DIV>
<DIV>It can be found with many different extensions: JPW, JGW (I think), TFW, WLD, etc.</DIV>
<DIV>I usually use the .WLD extension for all image formats (BMP, JPG, PNG, etc), which I think is recognized by all the software I have used so far. For example if you have a file.jpg and file.wld, both gvSIG and Gdal ( <A href="http://fwtools.maptools.org">http://fwtools.maptools.org</A> ) will recognize and use it.</DIV>
<DIV> </DIV>
<DIV>Regards,</DIV>

<P><FONT size=2>Edson,<BR><BR>The latest version of gvSIG is 1.9. Spanish manuals are available at<BR><A href="http://www.gvsig.org/">http://www.gvsig.org</A> and English versions are being prepared.<BR><BR>The manual for the earlier version, version 1.1.2, is available at<BR><A href="http://www.gvsig.org/web/docusr/manuales-en">http://www.gvsig.org/web/docusr/manuales-en</A> and discusses the basic<BR>concepts.<BR><BR>gvSIG can display and manipulate jpeg, jpg, gif, png, bmp and svg (+<BR>more). Although some require header files containing georeferencing data<BR>to be displayed correctly.<BR><BR>gvSIG can also connect to GeoDB, WCS, ArcIMS, WMS, Annotation and WFS<BR>internet services that can contain image data.<BR><BR>Usually JPG or PNG files require header files that contain the<BR>coordinates of the upper left corner and the pixel size. A typical<BR>example can be seen below.<BR><BR>For a file called "JPG_Image.jpg" you would have a corresponding file<BR>called "JPG_Image.jpgw". gvSIG also creates an "aux.xml" and "rmf" file<BR>with the same data.<BR><BR>The content of the different files look like this...<BR><BR>*JPGW*<BR><BR>0.3376811594201211<BR>0.0<BR>0.0<BR>-0.33768115942109755<BR>341082.7<BR>5814636.992753624<BR><BR><BR>*AUX.XML*<BR><BR><PAMDataset><BR><GeoTransform> 3.4108270000000001e+005, 3.3768115942012111e-001,<BR>0.0000000000000000e+000, 5.8146369927536240e+006,<BR>0.0000000000000000e+000,-3.3768115942109755e-001</GeoTransform><BR><Metadata domain="IMAGE_STRUCTURE"><BR><MDI key="INTERLEAVE">PIXEL</MDI><BR><MDI key="COMPRESSION">JPEG</MDI><BR></Metadata><BR><PAMRasterBand band="1"><BR><Metadata domain="IMAGE_STRUCTURE"><BR><MDI key="COMPRESSION">JPEG</MDI><BR></Metadata><BR></PAMRasterBand><BR><PAMRasterBand band="2"><BR><Metadata domain="IMAGE_STRUCTURE"><BR><MDI key="COMPRESSION">JPEG</MDI><BR></Metadata><BR></PAMRasterBand><BR><PAMRasterBand band="3"><BR><Metadata domain="IMAGE_STRUCTURE"><BR><MDI key="COMPRESSION">JPEG</MDI><BR></Metadata><BR></PAMRasterBand><BR></PAMDataset><BR><BR>*RMF*<BR><BR><?xml version="1.0" encoding="ISO-8859-15"?><BR><RasterMetaFile><BR><FLyrGeoRaster><BR><Extent><BR><X>341082.7</X><BR><Y>5814636.992753624</Y><BR><RotationX>0.0</RotationX><BR><RotationY>0.0</RotationY><BR><PixelSizeX>0.3376811594201211</PixelSizeX><BR><PixelSizeY>-0.33768115942109755</PixelSizeY><BR><Width>0.0</Width><BR><Height>0.0</Height><BR></Extent><BR><Dimension><BR><ImagePxWidth>138.0</ImagePxWidth><BR><ImagePxHeight>127.0</ImagePxHeight><BR></Dimension><BR></FLyrGeoRaster><BR></RasterMetaFile><BR><BR><BR><BR>Cheers Simon<BR><BR>Simon Cropper<BR>Botanicus Australia Pty Ltd<BR>PO Box 160, Sunshine, Victoria 3020.<BR>P: 9311 5822.
