The way to do this, is to first figure out the Backend of the map. If you use Chrome's Developer tools, and look at the Network Tab, you can Find out where the data is coming from. I found out that it coming from an ArcGIS Server REST endpoint at http://bhubaneswarone.in/arcgis/rest/services/.
You will find a number of layers, and say that I want to get the data for the BMC boundry, which is available at: http://bhubaneswarone.in/arcgis/rest/services/Boundry/MapServer/ The Actual Boundry is at layer number 2, and then you can query it by using the following URL http://bhubaneswarone.in/arcgis/rest/services/Boundry/MapServer/2/query?where=1%3D1&text=&objectIds=&time=&geometry=&geometryType=esriGeometryEnvelope&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=&f=geojson This gives you data in GeoJSON Regards, Devdatta On Tue, Aug 23, 2016 at 2:58 PM, Pratyush Mohapatra < [email protected]> wrote: > How did you scrape off the data? > > On Tuesday, 23 August 2016 14:42:03 UTC+5:30, Devdatta Tengshe wrote: >> >> Hi Pratyush, >> >> After you shared the link on the Slack channel, I scraped some of the >> data, directly from the ArcGIS backend. >> >> I've shared it at the following location: https://github.com/d >> atameet/Municipal_Spatial_Data/tree/master/Bhubaneswar >> >> Having the original data, as compared to digitized data is better, >> because invariably some errors are introduced when you Georeference, and >> Digitize data, based off that. >> >> Regards, >> Devdatta >> >> On Tue, Aug 23, 2016 at 1:33 PM, Pratyush Mohapatra < >> [email protected]> wrote: >> >>> Link to the geojson file: >>> https://github.com/Ativerc/GeoData/blob/master/BBSR_Wardmap_v0.1.geojson >>> >>> If you have any suggestions, please let me know. >>> >>> >>> Created by following the steps given here: >>> http://datameet.org/2016/08/12/guide-on-digitizing-static-maps/ >>> >>> So thanks NikhilVJ for that (why don't you put your contact links on >>> datameet's website?). >>> >>> About Bhubaneswar: >>> >>> Bhubaneswar is the capital of Odisha.
