I am new to GIS.
I was wondering how to go about taking geometry data (from AutoCAD) and attribute data (from Excel) and combining them into a single layer or shapefile or feature class. The AutoCAD data represents a street network for a city (e.g NYC) and the Excel file lists various types of pavement markings associated with segments along the aforementioned streets. So, for example, it would say "Starting at A street and continuing to B avenue, there are 10 bike diamond markings on the pavement and 8 pedestrian crossing markings). I feel a bit stuck regarding the most logical approach to unite this data.
How could I approach this task?
