comment Check/uncheck overlays in groupedlayercontrol.js
if app should open with Heatmap and Geometries on, and the others off - use option 'layers: [Geometries, Heatmap]' in L.map and delete '.addTo()map' options from this layers.

comment Visualization of a field in Leaflet
I have a similar situation - point data stored in PostGIS database and I need display heatmap of this points in web. I write shell script (put in cron for automatically update raster if changes values in points) which make next: 1. convert data from PostGIS table in local csv file (x,y,value) 2. using gdal_grid command I receive TIFF raster from values of csv file (invdist interpolation algoritm). 3. this raster clip by polygonal shapefile (gdalwarp command) 4. and new raster publish in GeoServer via WMS and connect them in Leaflet map

Hi Lee! I'am try use your script, but receive some troubles: I create in CentOS .sh file with content <code> #!/usr/bin/env Rscript library(foreign) dfBlocks = read.dbf("/source/farms.dbf", as.is=TRUE) strTract = unique(dfBlocks$name) for (i in length(strTract)) { strOGR = paste( "/usr/local/bin/ogr2ogr -overwrite -where \"name='",strTract,"'\" /destination/ /source/ farms -nln ",strTract,sep="" ) print (strOGR) system(strOGR) } <code>. When I run this script I receive only one first object from initial shapefile in destination folder.
