Hi Sidhardha,

Sorry for the late reply. I was out on vacation since Dev Summit 2019, then out on business travel.

>  ... the network analysis in arcmap some of the attributes such as (FT_COST and TF_COST) which ... are missing from that downloaded data (openstreet map data). Where can I have that data so that I could complete a network dataset without any error.

I would look/search for possible government open data sites like this one: Data.gov for your local region. Another option would be to look/search for 3rd party vendors who might sell network data for your region.

Or, you could purchase StreetMap Premium for ArcGIS

Hope this helps,

Also sir, when performing the network analysis in arcmap some of the attributes such as (FT_COST and TF_COST) which are very important for performing the process are missing from that downloaded data(openstreet map data). Where can I have that data so that I could complete a network dataset without any error.

Hi Sidhardha,

> My question is that while downloading the data from openstreet map we will not find all the attributes like (oneway,FT_cost,TF_cost...)

You will have to reach out to the source of where you downloaded the OpenStreetMap dataset and ask them if the dataset includes those attributes. You may want to reach out here, OpenStreetMap and OpenStreetMap Foundation.

Hope this helps,
