A trial was conducted to evaluate two procedures to map forest cutovers using Landsat data: a multitemporal band 5 overlay and multitemporal vegetation index difference. The satellite data had been geometrically corrected using the Digital Image Correction System (DICS). Both techniques were applied using the Canada Centre for Remote Sensing Image Analysis System.

Results of this study indicate that the "multitemporal band 5 overlay" technique show great potential as a cutover monitoring technique. The procedure is effective for cutovers with a grass or regeneration cover as well as for those with bare soil. According to this trial, the" multitemporal vegetation index difference" is impractical for delineation of cutover boundaries. The vegetation index indicates the presence of grass or other vegetation within cutovers. Clearcuts with an ingrowth of vegetation appear uncut using this procedure.

The two methods are discussed using Landsat data, photography taken concurrently with the second Landsat pass, and ground reference data.
