Hello everyone,</div>
<div style="margin-top:1em;margin-bottom:1em;font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif;font-size:16px;color:rgb(0,0,0)">
I'm using QGIS 3.34 and working with the vector-geometry-buffer function on a shapefile containing multiple spatial points, categories (or location type) are represented as a group of these spatial points. For each category, my goal is to calculate the geometries
(perimeter and area) created by the buffers. </div>

While the output result includes these geometries, it does not properly associate them with their respective categories. Instead, for each row in the output, I see the same category listed but with varying perimeters and areas, making it difficult to distinguish
which geometries belong to which category.</div>

Has anyone encountered this issue before? Is there a specific step or method I might be missing to properly link the geometries to their respective categories?</div></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto">What is your projection for your shape file?</div><div dir="auto"><br></div><div dir="auto">If it's not projected ie in lat-lon your buffer radius won't be interpreted as metres.</div><div dir="auto"><br></div><div dir="auto">Chris</div><div dir="auto"><div class="gmail_quote gmail_quote_container"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
