E.g., let's say three of the rasters are present at a particular cell, and the labels for those rasters are 'raster1', 'raster4', and 'raster7'. I would like the final map to have a label of 'raster1, raster4, raster7'.</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 14px/normal Helvetica; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 14px/normal Helvetica; ">Any and all suggestions are greatly appreciated.</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 14px/normal Helvetica; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 14px/normal Helvetica; ">Regards,</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 14px/normal Helvetica; ">John</div></div></body></html>
