Hi All,

 

 

I am using the raster mosaicker with lots of jpeg images (aerial imagery), but they are all at different resolutions eg: 7cm, 15cm and for different areas.

 

 

When I mosaic them the higher resolution images drop back to the equivelent of the lowest resolution.

 

 

How can I keep all the resolutions the same but also mosaic them into the one file?

 

 

Cheers

The RasterResampler will allow you to change the resolution of your images to a common resolution prior to using the RasterMosaicker.

Hi gisballarat!

 

 

To save space I would try to aggregate different resolution areas, and for each tile output set the RasterResampler to be the highest resolution for that area. With this method you will get a 15cm resolution for tiles only covering 15cm images (instead of using 7cm on all tiles for the whole project), 7cm on tiles with 7cm and 15cm coverage and 7cm on 7cm only. This will save some space if there is no issue mixing different resolution JPEGs on the output side.
