Solution: The default was Lambert II étendu (EPSG:27572) in ProgisCad 2002. In 2004, sometimes RGF93 / Lambert 93 (EPSG:2154). Try reprojecting with cs2cs.
A typical workflow for retro-engineering a legacy project looks like this:
Without the Progiscad family, you would have to manually digitize paper plots—a week-long job shrunk to 30 minutes. progiscad 2002 2004 adcof adfer adtopo hot
All were part of a software ecosystem by ADC or later GEOFIT (and eventually absorbed into other solutions like Mesuris, Covadis, etc.).
It is important to distinguish between abandonware and piracy. The original publisher of Progiscad has largely ceased support. However, using ADTOPO Hot cracks on active commercial projects may violate EU software directives. Practitioners typically use these tools under "right to repair" or "legacy data access" clauses. Solution: The default was Lambert II étendu (EPSG:27572)
For active engineering, consider converting to modern alternatives like Mensura or Covadis, which can read ADCOF files natively.
The identified terms refer to Progiscad, a now-obsolete French Geographic Information System (GIS) and CAD platform popular in the early 2000s for topographic, cadastral, and road infrastructure projects. The suffixes (ADCOF, ADFER, ADTOPO, HOT) represent specific modules, command sets, or data exchange protocols used between 2002 and 2004. No active support or modern compatibility exists for these components. Without the Progiscad family, you would have to
