A) i import a geojson file from france inside Manifold 9 ( cut..Edge) and don't succeed to select items locate inside drawing !! (I use keyboard press Ctrl and then mouse cursor click to seelct item )
1) add index on new mfd_id field don't work for enable selection
I add using schema a field mfd_id and a index mdf_id_x using btree on the mfd_id field . After this i was thinking i could select in drawing some item but not .
2) copy table create new table work
If i copy /paste the the table and create a new drawing base on this table then i can select item locate inside the drawing !!
Is it the default mfd9 behaviour ?
B) Does the geojson file spec define the default projection tourn:ogc:def:crs:OGC::CRS84
Does crs84 mean, is equivalent to EPSG:4326 ?
where is the table mamping beetween crs and epsg ?
where can i have more information about datum and latitude and longitude reference ?
