With the introduction of new imagery from satellites, digital cameras and the increased use of scanned film aerial photography, there is a great need for tools that quickly and cost effectively mosaic and georeference imagery to use in a GIS or Image Processing Systems. Unfortunately, methods for creating suitable input imagery typically require the user to either manage numerous individual image files (which can be cumbersome) or to acquire expensive orthorectification services. However, new technology and production processes, such as those found in DIME Software, have recently been developed to allow users to preprocess their imagery more efficiently so that it can easily become a useful addition to their GIS. This new, lower cost capability is particularly useful in applications such as Timber Management, Environmental Monitoring, or other Land Management activities and applications.
This paper will discuss innovative “image matching” techniques found in the new georeferencing and mosaicking Software called DIME and will highlight how DIME can be used as an alternative to traditional orthorectification processes. Specifically, an examination of how DIME georeferencing and mosaicking is being used in a variety of example applications to solve specific project problems in both commercial and governmental sectors.
