Change history for SeaMarks since version 7.0:
This lists the changes made to the program by release date. You can look over this list to see if your version might have a problem that has been fixed.
10/13/18 Fixed an error in the Garmin ADM export that prevented it from working that was introduced when the maximum file size was increased to 100,000 two months ago. 10/10/18 Modified the duplicate search so that 'exact' duplicates can have some very small difference in Lat/Lon and still be automatically deleted if that is the only criterion. 10/6/18 Fixed the GPX export so that Groups are sorted properly in the file for Raymarine. Took the description out of the GPX Routes export as it caused issues for some GPS models. Fixed the Sitex HY model Importer to ignore blank records instead of assuming the end had been reached when encountering one.
Changed Version number to 9.0
Made a change to the maximum file size from 32,500 to 100,000. This impacted 125 routines and caused about 300 changes. Most of the changes were in the 59 import/export routines as all had to be modified to handle this. Previously, if users had more than 32,500 points, the program would have them to split the file into multiple chunks. This mostly happened on track files. Fixed a few bugs found along the way. Spent a good part of the month testing the changes.
Fixed an issue that screwed up parsing the DDDMM.MMM style of Longitude. This mainly impacted track plotting.
Added more extensions to the Find Missing Files routine. They are: EVT, FWP, KAP, TSV, AND WPT. Added Mediterranean charts to the CD/USB load where needed.
5/20/18Fixed an issue with Garmin formats MPS and GDB due to a missing library file. 5/12/18 Improved the C-Map userimg.bin file importer to better handle fragmented files. If the user has had a long experience with the GPS and has deleted some sub files, the organization of this file can become very fragmented and hard to read. 3/30/18 Fixed an issue in the Hondex Export having to do with not having a leading 0 on longitude. Made sure the Lat/Lon format was right even if the user was using different format. Added icon and color recovery for importing Furuno GP1650/GP3300 MRK files. 3/14/18 Added recovery of the Date in the Offshore Hunter software import. Fixed a minor error in exporting a text file while using Loran Chain as one of the fields to be exported. Improved the import of Lowrance routes and trails. 2/20/18 Made the TZD icons import and export correctly as much as possible. Fixed an issue with the import and export of Humminbird GPX files with Groups. 1/7/18 Further fixed the TZD export to avoid a path not found error. Added a routine to the TDZ import to handle files with soft paragraph marks (line feed without carriage return). 1/3/18 Fixed an issue with the Furuno Time Zero (.TZD) import/export for windows 10 that was preventing it from working. 12/7/17 Added an importer for Hondex tracks and fixed the Lowrance/Simrad importer to handle version 6. Added a choice to the Backup/Restore capability to Select All for transfer and changed how it transfers BSB/KAP files so it works in a MAC. Changed version number to 8.8 11/10/17 Added importer and exporter for Hondex GPSs like the HDX-121 by Honda. This does the Event and Waypoint files. 10/10/17 Added an importer for the Koden_KGP model. Fixed an issue in the Sitex HY importer to avoid extra lines. Changed some Furuno TZD icon translations for import and export. Fixed an issue with the GPX exporter when used with Groups. 7/20/17 Fixed issues with saving a GPX file. Added an importer for the nwps32.txt style of file from a Northstar 951. 7/7/17 Fixed an issue in Importing Furuno NavNet3D points where an extra Carriage Return character would cause the import to fail. Also fixed an Icon issue in exporting to Furuno NavNet3Ds. 6/25/17 Added the 4990 chain to the ASF tables for the Central Pacific around Hawaii. Extended the ASF tables for the 7980 SouthEast US to better cover the Bahamas. Fixed an issue with export to Garmin GPX where homePort would not recognize the file. 5/30/17 Fixed an issue with the export to Humminbird GPX where the depth was reported as 10 times too high. 4/30/17 In Windows 10, the import and export of the Furuno TZD format and the import of Google Earth KMZ was not working, so that was fixed. In importing a text file, if the file had soft paragraph marks, it wouldn't work and that was fixed. . 4/3/17 Fixed an ASF table straddle issue where if the waypoint fell right on the border of the table and there was no adjacent table, it might not convert. Fixed an issue where some import/export routines would lock up the program in an infinite loop if a file was not where it was supposed to be. Added code to allow more loran lines in West Texas as the ratio of the line spacings was around 10 times. Added a GPX selection to Humminbird export. Added a Samyung GPS importer (no, that's not misspelled Samsung).
Changed the version number to 8.7
Cleaned up the Furuno GP39 GPX export to conform to Furuno requirements. Fixed an issue with the Calibrate Conversions routine due to an unrelated change elsewhere in the code. Added error handling on two routines that would crash the program on an error.
1/22/17 Had an issue with international use of a comma for a decimal point and fixed that. Put limits on Lat and Lon so that in the event the format was not quite right, nonsense values would not be displayed. Found that /windows 10 did not include a library called ComCtl32.ocx, so added that. Fixed an issue with importing Furuno TZD files.
Fixed an issue with the C-Map Userimg.bin files for a version I had not seen before.
11/28/16 Added capability for import and export of Furuno GP39, Import of GPX with Groups and modified the import of Humminbird version 5. Made changes to accommodate the new Raymarines.
Added importer for Furuno GP39
Added capability to Humminbird HWR importing to handle the newest version of that format.
Created a Save GPX with Groups exporter
Changed the way I do Zipping for formats like KMZ and TZD.
Fixed an issue with Furuno NN3D export in Windows 10..
Added an exporter for Sitex Hy format. Did some code cleanup.
Changed the version number to 8.6
Added an importer for Sitex Hy file type and fixed the Furuno NavNet 3D routes export . Changed the icon "X" for Google Earth export to lower case as upper case did not display. Added a point O on the error distribution display after calibration to mark the center of the plot.
Added an export for OziExplorer files. Fixed an issue where part of the screen did not get updated when returning from the File Properties dialog. Found an error in the Garmin importer where an icon was mis-identified. Added another importer for Garmin Routes to handle a version not seen before. Changed the calibration routine to save the file if doing an error distribution report since that replaced the data in the spreadsheet with another set.
1/16/16 Updated the Furuno NavNet 3D waypoint importer to handle the case where the 3 associated files are not present. Also to handle files where there are blanks between lines.
1/12/16 Updated the World Magnetic Model (WMM.DAT) file. This file has the world wide compass magnetic variation table. Without this update, an error message is encountered when opening the program. It unfortunately points to a defunct web site. The correct file is on this web site. Ignoring the message is OK as most people do not go by magnetic compass headings anymore.11/30/15 Fixed an issue with the Nobeltec ONF importer to handle a version not covered by the ONF specification document. Also corrected the C-Map XML importer that was giving 000 for the decimal part of Lat/Lon. This was introduced when I made changes for international considerations. Changed the Northstar 962 importer to show the file name the same as the file imported. 10/31/15 Added importers for NorthStar 962 floppy files, CAPN software, and Coastal Explorer software.
