Technical note

LCP to CAL: what to expect from the conversion

Every cell in an LCP file holds a measurement rather than a colour, usually elevation in metres, running from sea level up to whatever the highest point in the tile happens to be. CAL stores brightness, so the conversion stretches that range across a grey or colour scale. What you get is a readable picture of the terrain, and it is the right thing for a relief map or a figure. What you no longer have is the data: sampling a pixel in the CAL returns a shade, not an altitude. Missing cells in an elevation grid, such as water, radar shadow or the edge of a survey, are not empty: they hold a sentinel value, -32768 in SRTM, -32767 in DTED and very often -9999 in ESRI grids. Counted as a real height, that value stretches the scale so far that the actual terrain collapses into a few near-identical shades. When a CAL output looks flat and washed out, a void treated as data is the usual cause.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as CAL opens on any computer and any phone. reaConverter produces those from LCP in batch, entirely offline.

  • Render every file in a folder to CAL with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

FAQ

LCP to CAL Conversion

What are LCP files?

LCP (FARSITE Landscape File) is a multi-layer map file used by programs that simulate how wildland fires spread, such as FARSITE and FlamMap, which were developed for the U.S. Forest Service and other land agencies. To model a fire, the software needs to know what the land is like, and an LCP file puts that information together in one grid: the height of the ground, the steepness and direction of the slopes, the type of vegetation fuel, and how thickly trees cover the ground. Additional layers can describe the tree canopy and the litter on the ground. The format is widely used in fire management planning, and the national LANDFIRE program distributed its landscape data in this form for many years.

What are CAL files?

A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.
