<br />01835 <br /> <br />. <br /> <br />Image Resolution Consensus <br /> <br />. Initially, scientists felt they needed the (6.cm) <br />resolution provided by past aerial <br />photography. but the)' generally did not know <br />what resolution that was. <br /> <br />. After examining different image resolutions. <br />20-25 cm was fonnd acceptable for most <br />monitoring needs. In fact. scientists appear to <br />use the 44-cm image data. <br /> <br />. This lower resolution opened the door for <br />digital sensors, which cannot obtain 6 em <br />resolution, but can provide calibrated. <br />orthorectified data at 18 cm resolution. <br /> <br />. <br /> <br />. <br /> <br /> <br />17 <br />
