I want to create a multi-colored raster layer to overlay on my map in OpenLayers
I have the following information in my DataBase:
D_Cell_ID Long Lat ColorCode 055113 121.4698 40.8417 FF6600 057113 121.4698 40.8325 FF6600 . . . 063125 121.0344 40.4658 FFCC00 063127 121.0344 40.4567 FFCC00
I would like to have the output something similar like this:Example
Hence I need to write some code to create a raster image based on long,latt,color information.
Do anyone know how to do this or of any library tool which can import into Java environment to do this?
Method and direction is needed.
