<div><meta http-equiv="content-type" content="text/html; charset=utf-8"><span class="Apple-style-span" style="font-family: Verdana; font-size: 13px; ">Hi all, <br><br>I would like that every time a I use gdalwarp for some EPSG codes [1] transformation it would use by default the nadgrids [2] (for Portugal and Spain) that I have under the folder '/usr/share/proj/'.<br>
<br><div style="margin-top: 0px; margin-bottom: 0px; ">For that purpose in PostGIS I needed to add '+nadgrids=nadgrid_file_name.gsb' at the end of the line of the 'proj4text' field text in table 'spatial_ref_sys' for each EPSG code I wonted to use the nadgrid.</div>
<br><div style="margin-top: 0px; margin-bottom: 0px; ">So I suppose there must be a similar way of doing this with GDAL. How can I achieve this with GDAL?</div><br><div style="margin-top: 0px; margin-bottom: 0px; ">Thank's!</div>
