From time-to-time, I have the need to open tab files I have created in MapInfo with Google Earth Pro.
Aside from minor hiccups, I have never had an issue with importing a Tab file. The process I always follow in Google Earth Pro is:
File -> Open -> Select *.tab from File Type -> Select the file and pick the style template.
Recently, however, I have upgraded to MapInfo 15 (MapInfo 15.2 64-bit to be precise), and since then whenever I try to open a tab file in Google Earth, I only get the first item or 2 from the tab file and the remaining features (usually polygons) are lost. If I look at the tab in MapInfo, the data is present, so it seems MapInfo 15 is doing something differently that causes the tab file to not completely import into Google Earth Pro (GE version 184.108.40.2067).
Reverting to MapInfo 12 is not really an option, so is there anything else I can do to allow for Google Earth to completely parse these files?
To provide some additional details. I can take the MapInfo 15.2 created tab file and open it in MapInfo 12 without an issue on another machine. If I do "Save Copy As" from MapInfo 12 and create a new file, I can then open that file in Google Earth Pro just fine. But anytime I directly open a MapInfo 15.2 created tab file in Google Earth, I only get the first entry, sometimes 2 or 3. The remaining data is lost.
To add some additional info that I have come across recently, without upgrading either piece of software (still at the versions identified initially), I tried to open a list of locations identified by Lat/Lon that was created by MapInfo 15. There are 153 locations in the TAB file, but when I imported it into Google Earth, I got an error message from Google Earth saying:
Some features were not important due to invalid or out of range coordinates
and I only got 35 locations of the 153. All of the coordinates appear to be valid and there is only maximum span of just over 3 degrees for both Latitude and Longitude, so it seems illogical that there is actually something invalid in the TAB file (opening in MapInfo 12 and resaving it allows it to be imported to GE correctly without issue).
This is an example of a MapInfo 15.2 tab file that does not import completely into Google Earth
!table !version 950 !charset WindowsLatin1 Definition Table Type NATIVE Charset "WindowsLatin1" Fields 2 Column1 Float ; Column2 Float Index 1 ; begin_metadata "\MapInfo" = "" "\MapInfo\TableID" = "31fb8af6-d29c-4c9c-a8ec-bf9e82e3b343" "\MapInfo\ParentTableID" = "644f95b8-3201-4436-bdce-bdcff25c2a11" end_metadata
If I take a file that I have opened and resaved via MapInfo 12, the contents of the TAB file are identical, even though it will correctly open in Google Earth
I'm not an expert in the structure of the MapInfo file formats, but this leads me to believe that the issue is in the DAT, ID, or MAP files. It's almost like Google hits the end of a line and thinks it is the end of the file. Was there any structure changes in the MAP or DAT files that could explain this behavior?
