EPSG:4618 is a geographic coordinate system based on the South American Datum. And apparently somewhere GeoNode is not liking this coordinate system. If I convert the data to EPSG:4326 in QGis prior to uploading, it all works fine. Could it be that QGIS understands the .prj file for the EPSG:4618 but GeoNode does not and assumes EPSG:4326?<br><br></div>By looking at the ISO metadata from the EPSG:4618 layer, it tells me that the data is in EPSG:4326.

perhaps a silly question:<br>
<br>
(a) are you indeed having the same coordinate system (same prj
files?) for both shape files?<br>
(b) what happens if you not use epsg:4618 but some UTM? (sorry can't
figure exactly what 4618 is... it looks like geographic coordinates,
so perhaps a projection makes sense)<br>

</span>I've got two shapefiles with epsg:4618. One is a
polygon layer with loads of geometry errors and the second
is a point layer with the error location. When I load both
in QGIS, polygons and errors are aligned
(layers_qgis.png). I then uploaded the layers to GeoNode
(2.4b24) and points and polygons have shifted
(layers_geonode.png).<br>
<br>
I then added back the two layers in QGis using WMS
services. The points layer shifted a little (~8 meters -
point_error.png) but polygons shifted 69 m
(poly_error.png).<br>
<br>
Any idea what could be wrong?<br>
</div>
The shapefiles (poligon and points) can be downloaded from
the google drive links<br>

Thanks<br>
