Hello All,<div><br></div><div>I'm working on a new PRISM driver, and it can now read the rasterbands from all products. Now I'm working on reading the georeferencing data, and trying to set the affine matrix coefficients. The format specification* says in page 53 for one of the map projection fields:</div>
<div><br></div><div><br></div><div>Field No 58</div><div><br></div><div><div>Coefficient of F4 function (a, b, c, d, e, f)</div><div><br></div><div><div>x' a b x e</div><div> = +</div>
<div>y' c d y f</div></div><div><br></div><div>(x,y) : Map coordinate</div><div>(x',y') : Corrected Image address</div></div><div><br></div><div>Remarks:</div><div><div><br></div><div>
Map projection origin = (0,0).</div><div>In case of UTM, map coordinate at an</div><div>intersection of the equator and UTM</div><div>zone refelence (sic) circles of longitude = (0,0)</div></div><div><br></div><div>_____</div>

Just to confirm.</div>
<div>Many thanks in advance.</div><br>-- <br><span style="border-collapse:collapse;font-family:arial, sans-serif;font-size:13px">Ing. Rodolfo Bonnin<br>SUR Emprendimientos Tecnológicos<br><br>Perú 345 Piso 5to Oficina "B" (C1067AAG)<br>
