If you are creating Vector data, then it's best to keep the data in a geographic coordinate System with WGS84 as the datum. With today's technology, there is no specific advantage to keep your vector data in a custom projection. 6 decimal points are enough to have meter level accuracy, and you aren't going to need any more. Projection on demand is fast ...

Hava a look at OpenStreetMap. Take a look at this relation: http://www.openstreetmap.org/relation/3250963 where Telangana is included. You can download OSM land polygons from here: http://openstreetmapdata.com/data/land-polygons or daily updated data from here: http://download.geofabrik.de/asia/india.html

Admin boundaries below the taluka level are available only in the District Census Handbooks (where a map is given for each taluka or CD block). These taluka/CD block maps contain village and town boundaries (not boundaries of wards inside towns). These maps are not very accurate (spatially): our attempt to digitize and georectify these maps produces layers ...

If you want to use a postgis database with Openstreetmap data, you have to populate it with osm2pgsql, not osmosis. That is the only way to get polygons out of Openstreetmap multipolygon relations and closed ways in a format that GIS software can understand. Alternatively, you can use GDAL ogr2ogr to save OSM data into a spatialite database. Once you have ...

Expanding on my Comment, You should download the Administrative Atlas from here: http://censusindia.gov.in/2011census/maps/maps2011.html This has the data for all sub districts in India. It might not be an easy to extract format, but this is as official and exhaustive an list that you are going to get. You should know that division of districts is not ...

Shape files for India municipalities/village level won't be available as of now, But can be generated in QGIS or other such softwares by overlay digitization with background Web Map Services. India's Bhuvan is providing Web Map Service for 18 States at village or municipality level along with other numerous layers. To use WMS with QGIS this is a good ...

This is probabaly not the answer you are looking for, but here it is: You won't find them, since no one (not even the Postal Department) has Authentic Boundaries. Pin codes in India are a way of indexing Post Offices. Multiple Post Offices can have one pin code, and one Post Office can deliver to Multiple Pincodes. It's a Myth that there is such a thing ...

Perhaps DIVA-GIS may contain the shapefiles you're after with some corresponding boundaries. Select India as your country and your subject, I chose Administrative areas and received 4 shapefiles of differing levels. Choose the "IND_adm3" layer to see all the Mumbai areas within the Maharashtra district. Note: The shapefiles are outdated as Mumbai is still ...

You can get population data from Geonames. Not sure about the source of the population data, although it seems that such data coincides with Wikipedia's population data, which is from 2011. You would also need to validate that there are more than 600.000 Indian villages in Geonames. Regarding an automated way, you could follow this tutorial by Tim ...

You can get various Boundary datasets from here: https://github.com/datameet/maps/

Here's a link to the CORS map. And here's a link to a KMZ file of CORS sites. It doesn't look like India has a CORS network. It looks like most of the CORS locations are in the United States. Here's the website on other GPS Augmentations.

Apart from what has been mentioned already, you might consider using Bing Routing service that should be available in ArcGIS API for Javascript. I have personally seen the sample working with ArcGIS API for Silverlight though. The Bing Maps seems to cover India geographically, so the routing service should be available there even when accessing ...

The background image of the Openlayers plugin is a set of tiles in raster format. You can not convert that to anything useful. You can digitize the features you want on the basis of the background download Openstreetmap data (one of the available backgrounds of Openlayers) and filter that for the data you need.

This link from geofabrik.de provide shape files for roads and other features from open layers categorized into countries and for India covering almost all urban area. For urban boundary or district boundary shape files for India this link would be helpful.

You could use the approach of creating spatial weight index it is defined as: A spatial weights matrix is a representation of the spatial structure of your data. It is a quantification of the spatial relationships that exist among the features in your dataset (or, at least, a quantification of the way you conceptualize those relationships). Because the ...

Yes, please take a closer look at http://resources.arcgis.com/en/help/arcgis-online-network-analysis-rest-api/#/Overview_of_Network_Analysis_Services/02s500000007000000/ and http://resources.arcgis.com/en/help/arcgisonline/index.html#//010q000000pt000000.

The Telecom circles, or rather Telecom Service Areas (as they are now known) in India are roughly based on the Administrative districts. You can get the list of Services Areas from here: http://www.dot.gov.in/uas/Amendment%20dated%204%20Jul%2007%20to%20CMTS%20&%20%20UASL.pdf Based on this you could dissolve the district boundaries to get rough service ...

For soils you might take a look at the Harmonized World Soil Database (1km pixel size), and for vegetation you might be able to use the MODIS land cover product (500m pixel size). I would recommend the ESA's Globcover product for vegetation (300m), but their site seems to be under maintenance. As for water resources, I'm not familiar with any raster ...

EPSG:4326 is not the same as UTM :WGS 1984 44N. EPSG:32644 should be the projection that you want. It is based on the WGS84 ellipsoid, but using projected metres instead of degrees. And that is what your extent data looks like.

As I have said in my comment, you will not get the layers with 2011 census information. However village layer with 2001 census information are available from Survey of India at a fixed price. I have also found some data at this link: https://archive.org/details/IndiaVillageBoundaries I cannot vouch for its heritage, completeness or accuracy, but what ...

If you mean something similar to a CORS network, then IGS has a few stations in India: http://igscb.jpl.nasa.gov/network/complete.html I am looking for GNSS receivers active in India as well, hopefully a more dense network of receivers. I would guess that there are GAGAN stations with some information but if that data is publicly available I am not sure ...

For administrative boundaries, look at GADM database of Global Administrative Areas Select India, and choose "level 3". Edit: here's a screen grab of the resulting KML file, looks like it matches the link you provided, but GADM has it for the whole country.

I think the data is rather in meters in a projected local CRS. It might be necessary to add a high number constant to get the full coordinates needed for reprojection to WGS84. For India, a set of local coordinate systems has been established, see https://deeppradhan.heliohost.org/gis/indian-grid You have to know in which zone your data is collected. It ...

You can perform that transformation using cs2cs, a tool that is part of the Proj4 package. In case of need, you can find the proj strings for the Indian system(s) at SpatialReference.org.

Additional resources for subnational spatial data are available on this page. You can try the GAUL dataset, which provides yearly updates of administrative divisions at a global scale from 1990 to 2013.

OpenStreetmap seems to have some data: http://www.itoworld.com/map/4?lon=84.67111&lat=24.56236&zoom=7&fullscreen=true You can get the full source data of India from Geofabrik , and filter for the items you are interested in. But don't expect the data to be complete.

take a look at what I've got here - https://github.com/geohacker/india. Contains District, State and Taluk level shapefiles for India, based on the GADM data.

You can also download from DIVA-GIS: http://www.diva-gis.org/gdata Select India and then select the subject of the attributes such as: Administrative areas (boundaries) Roads Railroads Land cover Population
