Puff Tracking Animations in Google Earth

Puff Tracking Animations in Google Earth™  

Using the export to Google Earth feature, you can quickly and easily see where your puff will impact.  The play feature shows how your puff disperses over time.

CALPUFF View - Land Use Visualization

Auto-Download of Terrain/Land Use Data

CALPUFF View allows the user to automatically download global terrain data files (DEM, SRTM, GTOPO) and land use data (LULC, NLCD92, GLCC).  Easily process data for anywhere in the world.

CALPUFF View - Land Use Visualization

Sloped Roof Tool

This utility allows users to automatically create multiple building tiers based on the defined top and bottom tier to create the appearance of a sloped roof.
