Updating charts transas 5000 international datingagency

Today, the raster charts outsell NOAA's paper charts by eight to five.

Where no pixels were different between the old raster chart and the new, the patch acts like it has transpar- ent pixels and unchanged pixels from the old chart show through.At first, mariners will update the charts and store them on their hard drive.Then, as software developers modify their navigation packages, dynamic updating should be available.With dynamic updating, the charts and patches remain separate and the patch is "wiped over" the chart in real-time.This allows mariners to see that the patch is applied and to see what has changed, an important capability for mariners who transit a waterway frequently.Historically, new information was saved until about 50 critical changes had accrued and then the files would be updated and a new edition issued.
