Query an Arkansas GIS Layer: Attributes by Where Clause (Arkansas GIS Office)

arkansasgis/query-layer

Queries one layer of an Arkansas GIS Office FeatureServer or MapServer and returns its attributes (no geometry) as rows, filtered by a SQL where clause, 1 to 100 per call with an offset for the next page. Example: layer 48 of FEATURESERVICES/Boundaries is the county boundary layer with county, FIPS code, historic and 2020 population and area in square miles. Find layer ids and their credit line with the service layers tool; layers can carry their own credit lines. A bad where clause or field name is reported as an error.
