<p>Hi Neil,</p>
<p>just a note to your link: if you provide shapefiles, you'll have
to put at least 3 files: CC4a_RegionsSub.shp, CC4a_RegionsSub.dbf
and CC4a_RegionsSub.shx. (shp contains the geometry, dbf the
attributes and shx is the index between shp and dbf)..</p>
<p>best regards<br>

Hi all,<br class="">
<font class="" color="#5856d6"><br class="">
</font>I’m working with (1) a CSV file containing columns of “lat”
and “lon” which represent grid cell centroids from a gridded model
product over California (“loca_lat_lon.csv”), and (2) a shape file
that carves up California into 12 distinct subregions
(“CC4a_RegionsSub.shp”).
<div class=""><br class="">
</div>
<div class="">These files can be accessed here:</div>

class="" moz-do-not-send="true">https://drive.google.com/drive/folders/1IUrpVSJYBRIoCS4vzGYK9sBEzdwZec-c?usp=sharing</a></div>
<div class=""><font class="" color="#5856d6"><br class="">
</font>I am trying to determine which grid cells reside in each
of the 12 subregions (or NA/NULL if outside all subregions)
using Vector -> Data Management Tools -> Join Attributes
by Location. I have specified my Target vector layer as
loca_lat_lon.csv, the Join vector layer as CC4a_RegionsSub.shp,
the Geometric predicate as “intersects”, and am taking
attributes of the first located feature, and only keeping
matching records. <br class="">
<font class="" color="#5856d6"><br class="">
</font>The issue is that the returned joined layer assigns just
1 of the 12 subregions, “Sierra Nevada Mountains”, to all grid
cells, rather than different subregions (or None) to the cells. <br
class="">
<font class="" color="#5856d6"><br class="">
</font>The shape file has a CRS of NAD83/California Albers and
the coordinates in the CSV file are simply WGS 84. I’ve tried
resetting the latter CRS to NAD83/California Albers, but the
same issue persists. <br class="">
<font class="" color="#5856d6"><br class="">
</font>I’m using QGIS 2.18.14. <br class="">
<font class="" color="#5856d6"><br class="">
</font>Any help is greatly appreciated. Thanks in advance! <br
