Images supported by Geoagro GIS

From Wikiagro.com

Supported file types

When trying to import satellite imagery (or any type), please take into account what image formats are supported in GeoAgro GIS.

The following table shows the image formats supported by GeoAgro GIS, and whether they need to have an additional world file. A world file is a text file that contains specially formatted coordinate information about where the image is in relation to the surface of the earth. 

Image format	Supported by GeoAgro GIS	World File needed	World File format
PNG	YES	YES	PGW
TIF	YES	YES	TFW
SID	YES	YES	SDW
ECW	YES	NO
JP2	YES	NO
BIL	YES	YES	BLW
JPG, JPEG	YES	YES	JGW

Note:

Please keep in mind that the formats that work best in GAGIS are ECW and TIF (with no compression), this means that the system will be more responsive with this type of images

Warning:

The images should not be projected, that is, in Geographic Coordinate System - Datum WGS84. If you have projected imagery that you wish to import to your GAGIS project, they must be exported using the program that generated them to one of the formats listed above and in GCS WGS84.
