Hello all, I am trying to create a graph for network analysis using gdalgnm.The feature auto connect is working if we provide more than one layer.How can we connect features of a single layer so that graph is created automatically. We can connect features using connect features but automatically i

Hi Chaitanya, Thanks again. As i told, my data don't have layer M_SREL. But other application can read my data and show the QUAPOS attribute. So this attribute is not in that layer as you told. — *Đào Trọng Thắng* *Mobile:* 0919 262 988 Tầng 11 -
