FAQ
001 to STP Conversion
What are 001 files?
001 is the file extension of the first update to an electronic navigational chart (ENC) in the IHO S-57 format. Sea charts change all the time: a buoy is moved, a wreck is found, a channel is dredged, a depth is corrected. Instead of sending the whole chart again, the hydrographic office issues a small update file that lists only what is new, changed, or removed, and the first of them has the extension .001. The file has the same name as the base chart cell, whose extension is .000, and it cannot be used on its own. Later updates follow as .002, .003, and so on. Most of these changes correspond to the official Notices to Mariners.
What are STP files?
STP is a file format used by popular CAD software. STP contains 3-dimensional data saved in the Standard for the Exchange of Product Data (STEP, ISO 10303) file format.
