Ohio DNR GIS Layer Fields and Details (ArcGIS)

ohiodnrgis/describe-layer

Describes one layer of an Ohio Department of Natural Resources map service: its name, description, geometry type, extent, the maximum records per query and every field with its name, type, alias and length. Use it to learn the field names before writing a where clause for the layer query tool. The response also carries the layer's drawing and display settings.
