Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see DT1 data has GIS software. reaConverter renders it to PRC for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to PRC 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

DT1 to PRC Conversion

What are DT1 files?

DT1 is the file extension for Level 1 of Digital Terrain Elevation Data (DTED), a standardized elevation product described in the MIL-PRF-89020 specification of the U.S. National Geospatial-Intelligence Agency (NGA). Each file represents a one-degree by one-degree geographic cell and contains terrain heights sampled at a regular interval of 3 arc-seconds, equal to approximately 90 to 100 meters at the equator. Level 1 sits between the coarser Level 0 (.dt0) and the finer Level 2 (.dt2) products, and serves as a common choice for regional terrain analysis, flight planning, line-of-sight studies, and mapping at medium scales. The file starts with header records that identify the cell, its origin, and its accuracy, followed by the matrix of elevations. The format is a long-established standard in defense, aviation, and civil geospatial work.
