Hello,
I have two questions with ogr2ogr:
How do I remove features that have a null geometry?
I tried:
-where "\"geometry\" != null"
But got the error:
ERROR 1: "geometry" not recognised as an available field.
ERROR 1: SetAttributeFilter("geometry" != null) on layer 'entities' failed.
Here is the output in geojson without this filter that I want to remove:
{ "type": "Feature", "properties": { "Layer": "Table et accessoire",
"SubClasses": "AcDbEntity:AcDbBlockReference", "EntityHandle": "1972C" },
"geometry": null }
Note that during conversion, I get an error " Warning 1: Block Bloc truss
16X16X8 does not exist", so this may be that error, but I did have:
-skipfailures=true
Set, so I'm not sure why it would still be there if that is the error.
Second, my coordinates are in inches, and I would like them to be in meters. Is
there some way where I can convert and maybe round the result to meters? I
currently have:
{ "type": "Feature", "properties": { "Layer": "01_Grid-rigging", "SubClasses":
"AcDbEntity:AcDbMText", "EntityHandle": "15F4", "Text": "1" }, "geometry": {
"type": "Point", "coordinates": [ 4295.092091614642413, 4656.968211681276443,
0.0 ] } },
And would like:
{ "type": "Feature", "properties": { "Layer": "01_Grid-rigging", "SubClasses":
"AcDbEntity:AcDbMText", "EntityHandle": "15F4", "Text": "1" }, "geometry": {
"type": "Point", "coordinates": [ 109.1, 118.29, 0.0 ] } }
I'm wondering if -spat_srs or -a_srs would do this if I passed some kind of WKT
definition?
I would like to divide coordinates by 39.37 and round to the 2nd decimal place.
Thank you,
