Defining Shapefile Map Projections in Lakes Software Applications

A key feature of Lakes Software’s commercial products is the ability to easily import base maps in a wide variety of file formats. Supported formats include raster images (e.g., JPG, BMP, PNG, GIF, etc.), AutoCAD DXF, Digital Line Graphs (DLG), Shapefiles, and more.

CALPUFF View - Automated Coastline Download

One feature of the CALPUFF model is the ability to depict coastal interaction effects. Since the land surface can heat more rapidly than adjoining water, a Thermal Internal Boundary Layer (TIBL) can form and bring elevated source plumes close to the ground. This sets up a potential coastal fumigation scenario, which is illustrated in the figure below.

CALPUFF View - Defining Receptors in CALPOST

The CALPUFF model allows users to specify receptors in two different formats:

1. Gridded Receptors are defined as the Sampling Grid in which receptor locations are defined by the Meteorological Grid dimensions and extents.
2. Discrete Receptors are located based on user-defined coordinates for each individual receptor.
