Converting a Calibrated Image (KMZ) to a GeoTIFF

 CLICK ON THIS LINK AND WATCH THE VIDEO DEMO OF THE PROCEDURE

This post will demonstrate how to use the MAPC2MAPC software- (download the unregistered free version off the web and practice) to convert a KMZ image calibrated in google earth to a GeoTIFF Image for use in QGIS or any other GIS software.

Calibrated images are scanned images that have geographic reference to a location on the earth surface- more or less like saying georeferenced.

We are in no way advertising MAPC2MAPC software!!!!!!!

Task

To convert our calibrated image – ExpertGPS.Kmz- (Search for details in our previous posting- Adding Scanned maps to a GPS receiver using google earth..) to a GeoTiff format.
