The below simplified sketch illustrates what I am trying to do in Qgis. The SAPS Station shape has the data attributes and the Ward shape is the overlay or boundary shape. The output that I need is an attribute table that has calculated the % intersection of the SAPS Station by the ward boundaries and aggregated the crime attributes to a Ward table based on the % intersection. In the below sketch the ward boundaries intersect the SAPS Station boundary by 50% in both cases. As there were 100 crimes in the SAPS Station boundary the output table lists Wards 1 and 2 with 50 crimes in each.</div><div class=""><br class=""></div><div class=""><div class=""><span id="cid:ii_jmrgqim70"><image.png></span><br class=""></div></div><div class="">Any advise most welcome.</div><div class=""><br class=""></div><div class="">Regards</div><div class="">Brian O'Leary</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div></div></div>
