== File-based spatial index ==

Done in r38385 and r39148

== OGR interface ==

=== Direct OGR read access ===

Capability to read OGR layers directly without linking them via {{{v.external}}}. Example:

{{{
v.info map=~/shapefiles/@OGR layer=busstopsall
v.extract input=PG:dbname=nc_spm_08@OGR layer=busstopsall where="STREET_1 = 'William Moore Dr.'" output=b1
}}}

List of modules which supports direct OGR read access ((*) indicates work in progress):

 * {{{v.info}}} - r39161
 * {{{v.db.connect}}} - r39538
 * {{{v.extract}}} - r39621
 * {{{v.db.select}}} - r39556
 * {{{v.buffer}}} - r39809
 * {{{v.category}}} - r39812
 * {{{v.class}}} - r39813
 * {{{v.clean}}} - r39814
 * {{{v.delaunay}}} - r39821
 * {{{v.dissolve}}} - r39822
 * {{{v.distance}}} - r39823
 * {{{v.drape}}} - r39826
 * {{{v.extrude}}} - r39827
 * {{{v.generalize}}} - r39828
 * {{{v.hull}}} - r39829
 * {{{v.kcv}}} - r39832
 * {{{v.neighbors}}} - r39834
 * {{{v.normal}}} - r39839
 * {{{v.out.ascii}}} - r39881
 * {{{v.out.dxf}}} - r39882
 * {{{v.out.ogr}}} - r39883
 * {{{v.out.pov}}} - r39884
 * {{{v.out.svg}}} - r39885

=== Direct OGR write access ===

Capability to write OGR layers directly without need to store data in the native vector format and then exporting data using {{{v.out.ogr}}}. E.g.

{{{
# input: GRASS data
# output: PostGIS database
v.extract map=obce where="NAZEV = Solany" output=PG:dbname=gisdb@OGR olayer=obce

# input: PostGIS layer, ESRI Shapefile
# output: PostGIS database
v.select ainput=PG:dbname=gisdb@OGR alayer=zeleznice \
 binput=shps@OGR blayer=obce operator=intersects \
 output=PG:dbname=gisdb@OGR olayer=obce_zelez
}}}

== Redesign support structures ==

Reduce memory requirements particularly for points and lines. See ticket:542.
