ArcGIS Rest API returns No Results When Should Intersect

Question

I can download statewide NY senate districts using ...

https://tigerweb.geo.census.gov/arcgis/rest/services/TIGERweb/tigerWMS_Current/MapServer/56/query?where=STATE+%3D+36&text=&objectIds=&time=&geometry=&geometryType=esriGeometryPoint&inSR=&spatialRel=esriSpatialRelIntersects&relationParam=&outFields=*&returnGeometry=true&returnTrueCurves=false&maxAllowableOffset=&geometryPrecision=&outSR=&returnIdsOnly=false&returnCountOnly=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&returnZ=false&returnM=false&gdbVersion=&returnDistinctValues=false&resultOffset=&resultRecordCount=&queryByDistance=&returnExtentsOnly=false&datumTransformation=&parameterValues=&rangeValues=&f=geojson

When I query lat/lng against the api... I get zero results.

https://tigerweb.geo.census.gov/arcgis/rest/services/TIGERweb/tigerWMS_Current/MapServer/56/query?where=STATE+%3D+36&text=&objectIds=&time=&geometry=-73.831676%2C42.768687&geometryType=esriGeometryPoint&inSR=&spatialRel=esriSpatialRelIntersects&relationParam=&outFields=*&returnGeometry=true&returnTrueCurves=false&maxAllowableOffset=&geometryPrecision=&outSR=&returnIdsOnly=false&returnCountOnly=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&returnZ=false&returnM=false&gdbVersion=&returnDistinctValues=false&resultOffset=&resultRecordCount=&queryByDistance=&returnExtentsOnly=false&datumTransformation=&parameterValues=&rangeValues=&f=geojson

But when I map the statewide dataset and map the lat/lng I can see I should have an intersect. Can someone tell me why this intersect returns no results when the point falls within zone on the map???

Answer 1

The spatial reference of the service you are querying is different from the one one of your point (EPSG 3857 vs EPSG 4326). You are trying to specify a geographic point in a projected coordinate system and therefore you get no intersection. However, you can specify the spatial reference of your point in the query with the inSR parameter. If you specify inSR=4326 in the query url you will get a result. Check the fourth line of the following url versus the fourth line of your query. inSR is empty in yours.
