Working with Vector Data

QGIS supports vector data in a number of formats, including those supported by the OGR library data provider plugin, such as ESRI shapefiles, <A NAME="4"></A><A NAME="5"></A><A NAME="6"></A> MapInfo MIF (interchange format)<A NAME="7"></A><A NAME="8"></A> and MapInfo TAB (native format).<A NAME="9"></A><A NAME="10"></A> You find a list of OGR supported vector formats in Appendix <A HREF="#appdx_ogr"><IMG ALIGN="BOTTOM" BORDER="1" ALT="[*]" SRC="/usr/share/latex2html/icons/crossref.png"></A>. <P> QGIS also supports PostGIS<A NAME="12"></A><A NAME="13"></A> layers in a PostgreSQL database using the PostgreSQL data provider plugin. Support for additional data types (eg. delimited text) is provided by additional data provider plugins.<A NAME="14"></A> <P> This section describes how to work with several common formats: ESRI shapefiles, PostGIS layers, and SpatialLite layers. Many of the features available in QGIS work the same, regardless of the vector data source. This is by design and includes the identify, select, labeling and attributes functions. <P> Working with GRASS vector data is described in Section <A HREF="#sec:grass"><IMG ALIGN="BOTTOM" BORDER="1" ALT="[*]" SRC="/usr/share/latex2html/icons/crossref.png"></A>. <P>
