[GIS] Techniques for reducing a MapInfo TAB’s file size without losing too much integrity

file sizemapinfotab

What are some techniques for reducing a MapInfo TAB's file size without losing too much integrity? The file needs to be reduced for use, not sharing (i.e. zipping).

Best Answer

Depending what you mean by "integrity", there are a couple of things you could consider:

  1. Generalise the vector component to reduce the number of nodes - there is a tool HERE which you could use. Or you could try converting the file into Esri Shape (using Universal Translator) and using the generalisation approaches in mapshaper and translate back into Tab afterwards.
  2. Have a look to see if there are any redundant fields in the data - is there attribute data that isn't needed?
