I need to add this Lake County townships map into a shapefile that contains other counties' townships. The shapefile's fields are: Township, Shape, Shape_Length, Shape_Area and County.
How can I do this in ArcMap 10.4?

1are you sure this data doesn't exist in vector shapefile already?– Inactivated AccountCommented Apr 5, 2019 at 17:04

I found the map image on Lake County's website. portico.mygisonline.com/html5/?viewer=lakeinsurveyor The only formats available are png, bmp, jpeg, tiff, geotiff, pdf. I have searched all over the internet and can confirm there is no shp data for it.– RegulusCommented Apr 5, 2019 at 17:47

DPSSpatial's comment that this data might already exist in vector form is worth investigating as that's the easiest option. I would start by looking at the US Census.
If not, you'll have to digitize (trace) the features you want from your TIFF to create a vector shapefile with the same fields before combining it with your other data.

After extensive searching on US Census, including when I started the project yesterday, I haven't been able to find such data. They have demographic data for individual townships, but nothing like county maps with townships. I have created a feature class from 11 polygons, so I'll just add and populate the fields and load it into the main townships shp. Your comment is the answer, thank you.– RegulusCommented Apr 5, 2019 at 18:17
