Ohio DNR GIS Layer Query: Records by Where Clause (ArcGIS)

ohiodnrgis/query-layer

Queries one layer of an Ohio Department of Natural Resources map service with a SQL where clause and returns the matching records' attributes (no geometry), 1 to 50 per page with an offset for further pages; for example earthquake epicenters with magnitude 4 or more from DGS_Services/Earthquakes_EB layer 4. Field names come from the layer details tool. A where clause the layer cannot run, or a layer that does not exist, is an upstream error. Dates are epoch milliseconds. Data from the Ohio Department of Natural Resources, served by Eden Engine; not an official Ohio DNR product.
