[OpenLayers-Users] GeoTIFF display

[Andreas Hocevar]

Hi,

the problem is that most browsers don't support the TIF format. See http://en.wikipedia.org/wiki/Comparison_of_web_browsers#Image_format_support

So there are two prerequisites:
1) Your users have to use Safari
2) You have to know the bounding box and resolution of your GeoTIFF, because you do not have access to the EXIF information by means of javascript.

If you have that, you can use Layer.Image to display your tif. Note, however, that this does not make sense for large (i.e. more than a few megs) images.

So instead of going down this bumpy road, I'd suggest using GeoServer's RESTconfig API to create a data store and layer from your GeoTIFF. You can use JavaScript to do that.

Regards,
Andreas.
