<div dir="ltr">Hi All,<br><br>I'm facing in strange result using gdaltransform. What I'm doing is to try to trasform coordinates from WGS84 to Gauss-Boaga:<br><br>gdaltransform.exe -s_srs "WGS84" -t_srs "+proj=tmerc +ellps=intl +lat_0=0 +lon_0=9 +k=0.9996 +x_0=1500000 +y_0=0 +units=m +towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68"<br>
entering lon and lat<br>>7,69746 45,106977<enter><br>it gives <br>1342393.88434212 4984915.97865081 -47.0342488819733<br>doing the same transformation with qgis (same parameters), I have <table style="border-collapse: collapse; width: 141pt;" border="0" cellpadding="0" cellspacing="0" width="188">
<tbody><tr style="height: 12.75pt;" height="17"><td style="height: 12.75pt; width: 70pt;" align="right" height="17" width="93">1397559,446</td>
<td style="width: 71pt;" align="right" width="95">4995677,02 <br></td>
</tr></tbody></table>that is quite near to the target expected also checking out in map.<br><br>Do we know the reason of this delta? Do I have to set any other correction parameter?<br><br>appreciate<br>Antonio<br><br></div>
