Hi, Since this is an ArcGIS Server REST Service, one needs to be familiar with the REST API: ( https://developers.arcgis.com/rest/services-reference/map-service.htm)
Then One needs to know which layer/MapService is serving out the data that you need. And finally, you need to query the 'Query <https://developers.arcgis.com/rest/services-reference/query-map-service-layer-.htm>' end point of the appropriate end point Regards, Devdatta On Sun, Dec 23, 2018 at 8:09 PM Naraina Damle <cadvis...@gmail.com> wrote: > Hello, > > What do I need to do if I want to extract the Name of School and Lat Lon > in a particular area? > > On Sunday, May 22, 2016 at 6:14:31 PM UTC+5:30, Devdatta Tengshe wrote: >> >> Nihkil, >> >> There is a standard ArcGIS rest endpoint which is the backend for this >> here: http://rsgis.nic.in/ArcGIS/rest/services/?f=json. >> >> What data do you want to extract? >> >> Regards, >> Devdatta >> >> On Sat, May 21, 2016 at 4:04 PM, Venkata Pingali <pin...@gmail.com> >> wrote: >> >>> I looked at this site some months back.
