Hi Mike,
GeoTIFF support is build into OpenMap with the
com.bbn.openmap.layer.image.ImageTileLayer, but you do need to install
JAI.
Here are the properties I have set for the ImageTileLayer:
geotiff.class=com.bbn.openmap.layer.imageTile.ImageTileLayer
geotiff.prettyName=GeoTIFF
geotiff.imageFilePath=/data/geotiff/tif20/20meter.tif;/data/geotiff/
MM81442_Folder/MM81442LL.tif
geotiff.selectColor=FFFFFF00
In the imageFilePath, you can use directories or paths to specific
image files. The images need to be projected with WGS84 coordinates.
Hope this helps,
Don
