Hi Calvin<br>
<br>
One solution would be to use GDAL, a script like the following
(single quotes <small><small>(-a_nodata '-9999')</small></small>
for Linux, I believe)<br>
<br>
<b>gdal_rasterize -a "reading" -a_srs "EPSG:</b><i>your_srs</i><b><i></i></b><b>"
-a_nodata "-9999" -ot "Float32" -of "GTiff" -tr 2 2 -co
"COMPRESS=LZW" input.shp output.tif"</b><br>
<br>
That should interpolate the points to a grid for you!<br>
<br>
It can also be batched, an example of a windows batch for the above
would be<br>
<br>
<i>@echo=off</i><i><br>
</i><i>mkdir rasters</i><i><br>
</i><i>for %%f in ("*2m.shp") do gdal_rasterize -a "reading" -a_srs
"</i><i><b>your_srs</b></i><i>" -a_nodata "-9999" -ot "Float32"
-of "GTiff" -tr 2 2 -co "COMPRESS=LZW" "%%~nxf"
"rasters/%%~nf.tif" </i><i><br>
</i><i>pause</i><br>
<br>
just save it as a *.bat file for example magnetometry.bat<br>
<br>
Hope this helps,<br>
Regards,<br>
<br>
Richard.<br>

<div>I don't know how many of you have worked with
archaeological magnetormetry data, but I have been asked
to help with magnetometry data of the ancient Mound
Builders in North America. I am looking for some
suggestion on how to best turn the irregular magnetic
data points into an image.<br>
<br>
</div>
I see an Interpolation plugin that perhaps is the
solution, but I also see that it is not part of QGIS 3. Is
this because it has not been ported yet, or is not going
to be porter, or is there a better solution?<br>
<br>
</div>
I don't know if any of the Lidar tools would work for this
or not. LASTools is a commercial product and the locked
version only works with small data sets and adds noise
unless you purchase a license. At least that is how it was
the last time I used it.<br>
<br>
</div>
Thanks for any suggestions.<br>
