The client’s requirements are paid utmost attention and the work is done in close co-ordination with the client.A municipal GIS system is a GIS system which manages various tasks of a municipality such as property tax, birth and death registration, socio economic data management and holding registration amongst other tasks. The municipal GIS service also assists in generation of a geospatial view of the current municipal area linked with the corresponding up-to-dated database.The databases ideally possess attributes of every individual property with information such as land owner, co-owner, mailing & permanent address, house style, built year, individual room measurements, compliance with the regulations of the building authorities, public / private utilities mapping to the plot, street characteristics and amenities. There can also be a provision of linking every individual plots with their digital photographs, and a link to the map showing the location of the plot.

A municipal GIS System involves several steps including:

  • Computerization of land records
  • Digitization of existing spatial entities such as base maps
  • Updation of property records
  • Property Tax Assessment
  • Infrastructure database creation
  • Survey of the individual properties
  • Updation of the non-spatial database on a day to day citizen centric level

Urban Infrastructure planning, development and analysis for the future infrastructure requires a robust municipal GIS system in place. The generation of thematic map / zoning map created a high visual impact and is used for assessment of several sectors such as for water network planning, property mapping by assessor, snow plowing in temperate regions, maintenance of cities and civic amenities services, etc.The updated spatial and non-spatial database on the Municipal GIS system helps the concerned municipality to export and print the generated maps for any specific usage by the concerned field officer, or the property owner at any point of time thereby saving cost and time.A citizen centric service center is also organized wherein a daily updation of the spatial and non-spatial database is being taken care of, thereby keeping this Municipal GIS System in an updated position.

Cadastral Mapping

Cadastral mapping is a comprehensive register of the details related to the property of an area. These details include the precise location, dimensions, and other geographical classifications of the properties or individual parcels of land. The maps generated using cadastral mapping services help in effective management of public land records. National and local governmental bodies, architecture and engineering firms, real estate developers, industries can uses the cadastral mapping services for making well informed decisions. Cadastral mapping services also enable to user to study additional details, such as survey district names, unique identifying numbers for parcels, certificate of title numbers, positions of existing structures, section or lot numbers and their respective areas, adjoining street names, selected boundary dimensions and references to prior maps.Mappa provides cadastral mapping for creation of cadastral maps from hard copies of the administrative maps with specific details of each plot, roads, railway lines, water bodies, vegetation, etc. These cadastral mapping service provide all inclusive solutions to land information system problems by focusing on various forms of land records.

Mappa also has extensive experience of undertaking large scale cadastral mapping projects which include steps such as:

  • Scanning of hard copy maps
  • Digitization of the maps using proper layer structure
  • Geo-referencing the individual maps
  • Merging the individual cadastral maps to a single map pertaining to a specific area

The maps created using cadastral mapping services provide tools that support many types of record keeping, analysis and decision-making, high performance land surface modeling with data assimilation. These maps are created using high end software such as ArcGIS, ERDAS Imagine / ER Mapper, MapInfo, ArcFM, and AutoCAD Map.

Parcel Mapping 

Parcel Mapping is a process in which land parcels are created for efficient and effective land management. Parcel mapping service generates maps, created from base maps, with polygons that have details about the ownership of properties and other related information. The base maps used in parcel mapping are the cadastral maps showing each individual plots in different sub divisions. The land parcels are the fundamental data layer on which different data are referenced. Parcel mapping has a variety of uses such as land administration & property registration by urban and rural governing bodies. Municipality planning & urban development is taken care through the use of various parcel mapping techniques, which have the ability to restore analytical data that is crucial for enhancing the operational abilities of the government bodies.Use of parcel mapping services has increased over time and it has been observed that the time required to process and fulfil requests for land registry information has dropped by almost 80% in various countries. The use of parcel mapping services has consequently led to substantial improvements in handling the enormous requests generated over a period. Subsequently there is a huge reduction of overhead costs, and maintaining the data in a secured environment. Parcel mapping is also used by cartographic officials, rescue operations during floods and natural disasters for identifying property owners and retrieving crucial data. Parcel maps are also the base for any such GIS Maps.

Mappa can replace the cumbersome process of maintaining data on paper maps with digital parcel maps using parcel mapping for:

  • Municipal & other Urban Bodies
  • Government Departments
  • Builders
  • Real Estate Agents
  • Appraisers
  • Engineers
  • Surveyors
  • Developers

GIS Data Capture

 GIS data capture is a technique in which the information on various map attributes, facilities, assets, and organizational data are digitized and organized on a target GIS system in appropriate layers.

GIS Data capture can be divided into:

Primary GIS Data Capture Techniques: The primary GIS data capture techniques use remote sensing and surveying technologies to capture the data using either raster data capture or vector data capture.

The raster GIS data capture technique involves capturing of attributes and other data without physical contact. This is usually done with the help of satellite imaging techniques such as aerial photography. This type of GIS data capture is advantageous as there is a consistency in the data generated, and the whole process can be regularly and systematically multiplied to get accuracy of the data in a cost effective manner.

The vector GIS data capture technique includes capturing of data-sets through physical surveying techniques such as Differential Global Positioning System (DGPS) and Electronic Total Station (ETS). Although this technique is the most effective process to have the accurate data on the target GIS system, it is more time consuming and expensive.

Secondary GIS Data Capture Techniques:The secondary GIS data capture technique use technologies such as scanning, manual digitizing, vectorization, photogrammetry, and COGO feature construction to capture data by the following methods:

Scanning the raster data for GIS Data Capture involves the use of high resolution scanners that generate highly accurate raster images from the hard copies which can be geo-referenced and digitized to get the vector output.

Manual digitizing is done directly over the raster by the use of a digitizing tablet, which is a manual pointing device that creates an identical vector map on the computer screen, defining the vertices, points, line data, etc.

Heads-up digitizing is a part of GIS Data Capture and is similar to the manual digitization, but in heads-up digitization, the raster scanned data is imported and laid below the vector data to be traced on the computer screen itself.

Automatic raster to vector conversion is a great example of advancement of the technology, the technology uses special software using intelligent algorithms that have been developed to recognize the patterns of the points, lines and polygon features and capture them automatically to generate vector GIS data.

Photogrammetry involves digital stereo-plotters that are used to capture the vector data from the Ariel photographs, pictures and images. This is comparatively the most effective method of accurate GIS data capture, but is one of the costliest methods too.

GIS Data capture services provided by Mappa can used for:

  • Thematic Maps Creation: Analysing practical regional / cultural issues, transportation facilitation, hydrographic mapping, vegetation and other types of related features;
  • Capturing Electrical power networks using special software for GIS data capture
  • Capturing Navigation data for easy navigation
  • Capturing Land records and survey data for property, land, water and holding tax, etc. The spatial features are extracted from Ariel imagery using photogrammetry methods.
  • Creation of Utility infrastructure GIS data capture for water lines, road network, pavements, sewerage network, and other related features.
  • Generation of Environmental and geological GIS Data capture is done from geological maps, weather maps, mining and mineral exploration maps, etc.
