[mapserver-users] Kernel density layer tile clipping

[Dave Barter]

Can anyone help me troubleshoot some tile clipping we are getting when using Kernel Desity layers?

I have set up the layer as below but am still seeing tiles clipped at certain zoom levels. I tried increasing the tile size which improved things but not 100%:-

LAYER
 NAME feature_heatmap
 SIZEUNITS meters
 TYPE raster
 CONNECTIONTYPE kerneldensity
 CONNECTION "point_data"
 STATUS ON


 PROCESSING "RANGE_COLORSPACE=HSL"
 PROCESSING "KERNELDENSITY_RADIUS=25"
 PROCESSING "KERNELDENSITY_COMPUTE_BORDERS=ON"
 PROCESSING "KERNELDENSITY_NORMALIZATION=AUTO"
 OFFSITE 0 0 0

   CLASS
         STYLE
           COLORRANGE  "#0000FFFF"  "#FF0000FF"
           DATARANGE 0 255
         END
   END
   #MAXSCALE 29999
   DEBUG 0
END


Any ideas appreciated.
