GENERATE_DENSITY_GRID

The GENERATE_DENSITY_GRID command allows you create a new raster density grid layer based on vector points or point cloud returns.

• FILENAME - Name of a vector point or Lidar layer. Can only specify one layer name.

• LAYER_DESC - Description for the new Density Grid layer.

• DENSITY_TYPE - This option allows you to specify whether a weighted-distance Gaussian distribution is used (this gives much prettier results) or a simple in-or-out of radius calculation is used. Required parameter. Valid values are GAUSSIAN, CIRCLE, and EPANECHNIKOV.

• RADIUS – Used to specify how far from a grid sample location a point can be and still be considered as part of the value. Include unit abbreviation, e.g., '8 ft' for 8 feet. If no unit specified, the default meters. If the radius is not specified, a default value will be calculated.

• CELLS_PER_RADIUS - When combined with the Search Radius, controls how large the pixels are in the resulting density grid. For example, if you have a search radius of 90 meters and a 'Cells Per Radius' of 3, each pixel should end up 30 meters across. If not specified, the default is 3.

• POPULATION_ATTR - This option allows you to control whether a simple point count or attribute value is used to compute the density grid. Default is to just count points.

• AREA_UNITS - Units of area measure. Valid values are ACRES, HECTARES, SQUARE MILES, SQUARE KILOMETERS, SQUARE METERS, and SQUARE FEET.

• SHADER_NAME - this sets the name of the shader to use when rendering the data for this layer.
