MITAB 1.6.0 has just been released and posted to the website at http://mitab.maptools.org/
The main feature in this release is improved spatial index generation code that produces an optimized R-Tree and gives spatial search performance comparable to TAB files generated by MapInfo (up to 30 times faster than the spatial index of MITAB 1.5.1 on some searches). Thanks to Aircom International (Andrew Blake) for funding this work. Full details in MITAB bug 1585: http://bugzilla.maptools.org/show_bug.cgi?id=1585 Note: Unfortunately, the new spatial index generation code is about 5 times slower when writing files. This is mostly noticeable when writing very large files. The complete list of fixes since 1.5.1 is included below. Daniel Version 1.6.0 (2007-02-15) -------------------------- - Improved generation of the .map's internal spatial index and object data blocks to produce an optimal r-tree, resulting in performance improvements of up to 30 times faster on some spatial searches, matching the perfomance of files generated by MapInfo. (bug 1585) (Thanks to Aircom International (Andrew Blake) for funding this.) - Fixed problem with null brush bg color becoming black when parsing style strings (bug 1603) - Added mitab_is_field_indexed() and mitab_is_field_unique() to C API (bug 1621) Yahoo!
