<p>Hi Juliana,</p>
<p>First, I would investigate with Carto, if you really cannot embed
a WMS. It would be much better to use the webservice directly
rather than downloading and uploading and then end up with an
outdated image.</p>
<p>If that does not work, you need to set a meaningful resolution.
As we can see in your screenshot the resolution text input fields
are empty. Also check if the projection is correct. Do you really
want to save in EPSG:4326 or rather in a meter based system?</p>
<p>What kind of data are you saving? Orthoimages or maps with few
colors or black and white? If it is orthoimages, I would use JPEG
compression in the Geotiff, otherwise probably deflate/LZW.</p>
<p>Then you have to find a meaningful resolution. If you really want
to save in EPSG:4326, you have to specify a resolution in decimal
degrees. Try with larger values first, such as 0.05 and then, if
it is too coarse go to smaller values.</p>
</span><p>About polygonizing raster to vector: this really depends on the
content - and I kind of doubt it if you really get meaningful
results. Maybe it works with few colors and homogeneous areas. It
certainly would not work well for aerial images.<br>
</p><span class="">
Hope it helps,<br>
Andreas<br>

thanks for your reply.<br>

I chose layer extent for extensions and current layer for
resolution but still doesn´t work. <br>

About the bigger question, no, CARTO doesn´t allow uploading
geotiffs. What I´ve done so far is polygonizing the rasters in
QGis and uploading the converted shapefile to CARTO. As you
said WMS can´t be converted into shape, I´m not sure this is
going to work at all... won´t I be able to polygonize a raster
downloaded from a WMS server?<br>
<br>
All the best, Juliana.<br>

<p>Hi Juliana,</p>
<p>"Save AS" as a WMS should work fine - but you need to
specify a useful extent and resolution (in map units of
your projection). Otherwise it probably fails.</p>
<p>I just tested it and it works fine.</p>
<p>The bigger question is: will CARTO allow to upload
larger Geotiff files? Did you check that?</p>
<p>Note that WMS are always raster. You can't convert it
into a shp file.<br>

<div dir="ltr">Hello,<br>
<br>
I have loaded a wms server to QGis, which is a
raster format. As I need to use this in an
external aplication (CARTO) which does not support
wms, I´m trying to export the server loaded into
QGIS through "save as" funcionality. But it´s not
working.<br>
<br>
Do you know how I can export the wms loaded to a
file (raster or shp)?<br>
<br>
Thanks a lot, Juliana.
