Smart City One Geoportal Solution

Need

A large municipal administration organization managing 110 municipalities lacked spatial decision support tools to manage all its Assets, Revenues like Property tax and Water Charges and Grievances from the citizens.

Approach

Spatial Decision Support for Municipalities:

  • Vassar Labs used its GIS Solution to build a Geoportal that shows all the 110 municipalities that the Department manages on one unified spatial dashboard
  • Each municipality is shown along with each locality, ward and other geographical sub-divisional boundaries.
  • Within each municipality different land parcels and buildings are shown in the Geoportal and can be searched by Building/Parcel ID, Address, Owner Name and Mobile Number.
  • Infrastructure like Roads and Rail Network is shown for all municipalities
  • Utilities information like Drainage and Sewer Network, Drinking Water Tanks and Supply Network, Electricity lines, Street Lights and Transformers, Cell Phone towers for the municipality are represented in the Geoportal
  • Natural resources like Streams/Canals and trees are shown on the portal
  • Community facilities like Pubic Toilets, Public drinking water pumps and water taps are shown on the Geoportal
  • Different places of interest like ATMs, Banks, Hospitals, Shops/Malls, Places of Worship, Places of Entertainment, Restaurants and Industries are all shown in the portal
  • Property tax, Water Charges: Property Tax collections in the entire state are highlighted with different colors based on targets with an option to search on Bill Collector responsible for collections, Building/Parcel ID, Address, Owner Name and Mobile Number. One can zoom up to a parcel or building and look at all the details.
  • Grievances: A spatial dashboard for the entire state which can be zoomed all the way up to ward/locality within each municipality with performance of Citizen Grievance Redressal within and outside SLA are shown. The details of public officer in-charge is also provided and appropriate alerts are raised.
Benefit
  • The department was able to effectively add all the assets under 110 municipalities onto one geoportal
  • One unified spatial dashboard to track performance of different municipalities, wards and different localities within each municipality on Property Tax and Water charge collections, Citizen grievances and other performance metrics
  • An interface to perform search for multiple public utility functions and information dissemination

Water Resource Information Geoportal

Need

The state of Andhra Pradesh wanted to build a geoportal for all the water assets in the state along with integrating other related information.

Approach

The state of Andhra Pradesh used Vassar Labs Geospatial Informatics solution to build a geoportal on Open Source platform integrating data from different sensors, satellite data, crowd sourced data and Hydrology/model derived data.

Following are the salient features of the geoportal built for capturing all the water resources in the state

  • Integration of different Base layers – Bhuvan, DEM, Open Street maps, Latest Satellite image from Sentinel-2
  • Agricultural parameters like Latest NDVI and Moisture Index
  • Different Administrative and Hydrological boundaries in the state
  • Rivers and Streams in the state along with Drainage Network
  • Different Surface Water structures like Reservoirs – Major, Medium and Minor and Water Spread Area for each of these
  • Canal Irrigation Network
  • About 1 million Water Conservation Structures
  • Ground Water Aquifers, Borewells, Ground Water Resource estimation maps, Real time data from 1250 Ground Water level sensors
  • Hydromet data including spatial distribution of Rainfall and Soil Moisture from 1800+ real time sensors and 900+ soil moisture sensors
  • Ability to pick a district or a block and Search
  • The geoportal can be accessed online at
    http://www.apwrims.ap.gov.in/geoportal/wcm

Benefit

One unified view integrating all water assets and other databases onto one web enabled platform.

North East Water Resources Information Base – A geoportal funded by World Bank


Need

To create a web based geoportal which can be a central repository of spatial and temporal water data and related reports, documents and studies done in North-Eastern States of India.

Approach

Various Base layers like Bhuvan, Open street maps, Stamen Terrain and Carto dem were integrated.

The Overlay data layers integrated include:

  • Administrative Layers (State, District, Block, Village)
  • Road/Rail Network
  • Hydrological (Rivers, Basins/Sub-Basins)
  • Canals (Main, Branch, Distributory)
  • Surface Water Structures (Dams, Reservoirs, Canal Command Area, Minor Reservoirs/Tanks)
  • Surface Water Spread (Water Occurrence Change intensity, Maximum Water Extent including wet lands, Water Transition, Latest Water Spread Area)
  • Hydromet data (Precipitation, Temperature), Sensor data from various agencies Contour
  • Land Use/Land Cover
  • Soil Depth and Soil texture
  • Ground Water Prospects / Aquifers / Ground Water
  • Forest Tree Cover / Forest Tree Cover Loss/ Forest Tree Cover Gain/ Active Forest Fires in the past week
  • Different Projects like Hydro Power Projects
  • Disaster Related (Inundation Map/Erosion and Deposition/Embankment Inventory/Breach Locations/ Sand bars/ Earthquake Incidents)
  • Agriculture Data /Population
  • Thirty years of historical weather data was integrated into the geoportal
  • 500+ documents including DPRs, Project Reports and Research papers were integrated to the portal to make an eLibrary that can be accessed by different users depending on the security levels of the document

The geoportal can be accessed online at

Benefit

One single source of truth for all the water and related data for all the under developed North East states in one geoportal

This facilitates any development of decision support as the data is on one integrated platform

Drone data Analytics for Unauthorized Construction, Road Quality and Sanitation


Need

A large Municipal Administration Department that manages 110 municipalities wanted a solution that can provide Decision Support for analysing Unauthorized construction, Road Quality, Sanitation in the municipalities using Drone data and to automate monitoring.

Approach
  • Vassar Labs used its Geospatial Informatics Solution to ingest the drone data from the municipalities with a 3 cm Ground Spatial distance.
  • These images are processed to obtain the 3D polygon structures of the buildings roads and drainage network. The image and 3D polygon data is then super imposed on the base maps for points of reference.
  • The 3D polygon data is compared to the permission data present in Development Permission Management system of the municipalities to identify deviations to the plan.
  • The deviations are then passed back field level functionaries for validation and necessary action.
  • The subsequent drone flight is further used to identify if there was a intervention taken by the field level functionary or further deviation has taken place from the plan.
  • In addition to the new buildings, the 3D polygon data is also matched against the property tax system to identify the buildings without property tax assessments and permissions. Necessary decision support is provided to the field functionaries in assessing and collecting the property tax
  • Any new structures or constructions identified from the drone imagery is used to update the GIS based maps of the city.
  • Drone data is used to classify the objects into Roads, Trees etc. and the extent of Green Cover is estimated and is also monitored for each of the municipalities
  • Any Road Quality issues are identified and necessary functionaries are alerted.
  • Sanitation issues in the municipalities are also identified and necessary field functionaries are alerted to take necessary action. The system also monitors if an issue identified has been rectified.
Benefit
  • The department can get a view of the cities infrastructure and constructions at a glance after every drone flight without the need for extensive ground level validation activity.
  • Effective identification and monitoring of resolutions for Code violations, Road Quality, Sanitation, Green Cover estimation etc.
  • Helps in urban planning and infrastructure requirements for future needs of cities/municipalities.
