1 OGR总览

OGR用于矢量处理，作为GDAL/OGR的一部分发布，全局参数中部分与GDAL共享。

1.1 设置编码类型

参见：GDAL应用.docx中GDAL_FILENAME_IS_UTF8。

2 OGR工具

2.1 ogr2ogr:矢量格式转换，并可以设置各种属性（坐标系转换、属性设置等）

Usage: ogr2ogr [--help-general] [-skipfailures] [-append] [-update]

               [-select field_list] [-where restricted_where] 

               [-progress] [-sql <sql statement>] [-dialect dialect]

               [-preserve_fid] [-fid FID]

               [-spat xmin ymin xmax ymax] [-geomfield field]

               [-a_srs srs_def] [-t_srs srs_def] [-s_srs srs_def]

               [-f format_name] [-overwrite] [[-dsco NAME=VALUE] ...]

               dst_datasource_name src_datasource_name

               [-lco NAME=VALUE] [-nln name] [-nlt type] [-dim 2|3|layer_dim] [layer [layer ...]]

Advanced options :

               [-gt n]

               [-clipsrc [xmin ymin xmax ymax]|WKT|datasource|spat_extent]

               [-clipsrcsql sql_statement] [-clipsrclayer layer]

               [-clipsrcwhere expression]

               [-clipdst [xmin ymin xmax ymax]|WKT|datasource]

               [-clipdstsql sql_statement] [-clipdstlayer layer]

               [-clipdstwhere expression]

               [-wrapdateline] [-datelineoffset val]

               [[-simplify tolerance] | [-segmentize max_dist]]

               [-addfields]

               [-fieldTypeToString All|(type1[,type2]*)] [-unsetFieldWidth]

               [-fieldmap identity | index1[,index2]*]

               [-splitlistfields] [-maxsubfields val]

               [-explodecollections] [-zfield field_name]

               [-gcp pixel line easting northing [elevation]]* [-order n | -tps]

示例：将当前文件夹下所有shp文件转换为kml

::only after set utf8=no, you can use gbk

set GDAL_FILENAME_IS_UTF8=NO

md kml

for %%i in (*.shp) do ogr2ogr -f KML"kml\%%i.kml" "%%i"

2.2 ogrInfo

2.3 ogrTIndex

2.4 ogrLineRef
