The majority of formats require the same two steps for visualization on a Lightspeed view. To visualize Oracle Spatial data:
-
Decode the data into an
ILcdModel
using anILcdModelDecoder
. -
Create an
ILspLayer
for theILcdModel
and add it to theILspView
.
//First create the model
ILcdModelDecoder decoder =
new TLcdCompositeModelDecoder(TLcdServiceLoader.getInstance(ILcdModelDecoder.class));
ILcdModel model = decoder.decode("Data/Oracle/san_francisco.ogr");
//Create a layer for the model with default styling
ILspLayer layer = TLspRasterLayerBuilder.newBuilder()
.model(model)
.build();
//Add the layer to the Lightspeed view (an ILspView)
view.addLayer(layer);
The file passed to the model decoder is a Java Properties
file. It contains all the information that the model decoder requires to connect to the database.
For example, the file specifies the location of the database, which table to use, and so on.
The content of that properties file is documented in the class javadoc of the
TLcdOracleGeoRasterModelDecoder
class.
This results in a Oracle Spatial layer with default styling. See Visualizing Raster Data for more information about visualizing and styling raster data.
