Technical note

Before you convert SHX to CAL

An SHX file holds geometry and an attribute table, and nothing at all about appearance. Colours, line weights, fills and labels are properties of the GIS project rather than of the file, which is why the same SHX looks different in every program that opens it. The CAL render therefore falls back on defaults and will not match the styled map you see in QGIS or ArcGIS. Expect a clean drawing of the geometry rather than a finished cartographic product. SHX describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the CAL afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see SHX data has GIS software. reaConverter renders it to CAL for a report, an email or a slide, and handles a whole folder in one run.

  • 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.

I firmly believe working with JPEG — the universal format supported by all devices and apps—is the wisest choice. reaConverter handles these conversions flawlessly.

FAQ

SHX to CAL Conversion

What are SHX files?

The SHX file is an essential component of the Shapefile format, used in geographic information systems (GIS). It contains the positional index of feature geometry, allowing software to quickly access spatial data stored in the accompanying .shp file. The .shx file must be present alongside .shp and .dbf files for the shapefile to function properly.

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.
