Ogrinfo Output Formatting

Written on Oct 21, 2016 and marked as gdal | automation

Today my workmate asked if there was a way to see an attribute table other than importing spatial data into a PostGIS database. I told him about QGIS and while talking about other GIS stuff, I started thinking about pipes and how awesome it would be to actually format the output of the ogrinfo command.

Here it is. It is just a much longer way to do ogr2ogr -f "CSV" dest source, but sometimes you just have to experiment a bit.


function columns {
    ogrinfo $FILE -al -so | \
    sed '/Column/,$!d' | \
    sed '/Geometry Column/d' | \
    sed -e 's/Column =/\:/g' | \
    awk -F: '{print $1}' | \
    awk -v RS= -v OFS="|" '{$1 = $1} 1'

function data {
   ogrinfo $FILE -al | \
   sed '/OGRFeature/,$!d' | \
   sed -e 's/OGRFeature\(.*\)\://g' | \
   sed -e 's/.*\s*\(.*\)\s*=\s*//g' | \
   awk -v RS= -v OFS="|" '{$1 = $1} 1'

{ columns; data; }

The result can be piped to other bash functions, such as less or more. I call it ogrinfotable.
