1 <br />0 0 <br />3. Landsat Imagery for Arkansas River <br />Table 2 lists recommended Landsat scenes for purchase from the USGS. The multidate imagery covers <br />irrigated lands along the Arkansas River main stem. The recommended imagery were selected for the <br />Arkansas River irrigated lands but they also include irrigated lands along the Purgatory River and <br />Fountain Creek. Based on visual inspection of thumbnail images of the Landsat frames (Appendix), we <br />have determined that three Landsat frames -- 33/33, 32/34, and 31 /34-- should cover the entire irrigated <br />acreage along the Lower Arkansas River Basin. However, this cannot be confirmed until the actual <br />imagery is acquired. <br />Charts showing temporal signatures of major crops in the South Platte River Basin along with the <br />recommended dates for Landsat images are provided in the Appendix for each of the Landsat frames. <br />These charts demonstrate that the satellite image dates should be appropriate for classifying crops in the <br />Arkansas River basin, which has crop types and agricultural practices similar to those in the South Platte <br />basin. In addition, a thumbnail print of each recommended satellite images provided in the Appendix. <br />Table 2: Recommended Landsat Imagery for 2003 Irrigated Lands Assessment <br />Frame <br />Patb/ <br />Acquisition <br />Image ID <br />Sensor <br />Cloud <br />Comments <br />Cost <br />Date <br />Type <br />Cover <br />Row <br />33/33 <br />04/16/2003 <br />7033033000310650 <br />TM7 <br />0% <br />Good quality; no clouds evident <br />over Arkansas river irrigated lands; <br />$ 600 <br />Clouds over mountains; thumbnail <br />33/33 <br />05/26/2003 <br />5033033000314610 <br />TM5 <br />20% <br />shows some haze over Arkansas <br />$ 450 <br />river; <br />33/33 <br />06/27/2003 <br />5033033000317810 <br />TM5 <br />5% <br />Few scattered clouds over NE <br />$ 450 <br />corner; <br />33/33 <br />8/14/2003 <br />5033033000322610 <br />TM5 <br />0% <br />Good Quality; no clouds evident <br />over Arkansas river; <br />$ 450 <br />33/33 <br />9/15/2003 <br />5033033000325810 <br />TM5 <br />0% <br />Good Quality; no clouds evident <br />over Arkansas river; <br />$ 450 <br />32/34 <br />5/11/2003 <br />7032034000313150 <br />TM7 <br />0% <br />Good quality; no clouds evident <br />over Arkansas river irrigated lands; <br />$ 600 <br />Few clouds in SW corner; <br />32/34 <br />7/6/2003 <br />5032034000318710 <br />TM5 <br />2% <br />thumbnail shows no clouds evident <br />$ 450 <br />over Arkansas river irrigated lands; <br />Scattered clouds over western <br />32/34 <br />7/22/2003 <br />5032034000320310 <br />TM5 <br />5% <br />section of Arkansas river irrigated <br />$ 450 <br />lands; <br />Scattered clouds over eastern <br />32/34 <br />9/8/2003 <br />5032034000325110 <br />TM5 <br />5% <br />section of Arkansas river irrigated <br />$ 450 <br />lands; <br />32/34 <br />9/24/2003 <br />5032034000326710 <br />TM5 <br />0% <br />Good quality; no clouds evident <br />over Arkansas river irrigated lands; <br />$ 450 <br />Page 2 of 4 PRiverside Technology, inc. <br />l� Water Resources Engineering and Consulting <br />
