Anyone using ImageJ to read-write GeoTIFF Images

[Dr. Raj Cherukuri]

Hi,

I am still using ImageJ software in my project work. I am attempting to read-write Tagged GeoTiff from LANDSAT 8 satellite imagery. But, ImageJ balks during the File->Open command, stating that it 'Cannot open Tagged TIF files'. Are there any plugins available that can read-write from Tagged GeoTiff satellite imagery?. Any useful pointers are appreciated in advance.

Best Regards

Dear Rajabhushanam,

could you post an example or an link to an example. I know several libs to open geotiff files.

The easiest pure Java library solution is to use the Commons Imaging library which supports geotiff.

In my application I use rgdal and Java GDAL (in WorldWind) to open georeferenced geotiffs.

Best regards

Marcel

Hi,
I'm looking for somethink like this too. I use ImageJ for create NDVI map from geotiff images, but I can import those images. And if I want to use other kind of image, like png, ImageJ change the transparency by something else, so I can't use coordinates anymore (upper left, upper right... have change). Any idea how to import geotiff, work on it and export?

Thanks
Alex

In my current release of Bio7 - http://bio7.org (which embedds ImageJ and R) I integrated a new dialog to transfer Imagej ROI measurements to R as SpatialPolygonsDataFrame, SpatialLinesDataFrame or SpatialPointsDataFrame georeferenced from a geotiff file, see:

It is also possible to import images to R and ImageJ with some import scripts and export the manipulated geotiff with R (rgdal, maptools, sp packages have to be installed in R).

It is also possible to send the image data from ImageJ to R and create a georeferenced image in R from the pixel data (set the extent and e.g. the projection).
