Step 3.

click yelp category list

https://transparentgov.net/json2tree/gateway/yelp/pan-zoom-marker-label-category.html?layer_id=18&url=https%3A%2F%2Fpublic.gis.lacounty.gov%2Fpublic%2Frest%2Fservices%2FLACounty_Dynamic%2FPolitical_Boundaries%2FMapServer&layer=County+Boundaries&panto=0&center_lat=35.2838614435733&center_long=-118.90518688516013&center_zoom=8

 

 

Step 4.

find police, click it, 

arrow  means cat. alias, it has no space,  cat. alias is actually used as parameter in rest api endpoint.  

You can copy either alias, or full name, paste in cat. input box in all model, 

 both alias and full name works because I convert full name to alias behind the scene. In fact, yelp api only use alias, not accepting full name.
