Development Plan and GIS
  • Development Plan is a term associated with towns and cities. In India, Development Planning of towns is primarily the responsibility of ‘Town Planning Department’ of the respective State Government under the relevant Town Planning Act. As per Maharashtra Town & Regional Planning Act, 1966, Development Plan (DP) means a plan for the development or re-development of the area within the jurisdiction of a Planning Authority. A Development Plan shall generally indicate the manner in which the use of land in the area of a Planning Authority shall be regulated, and also indicate the manner in .which the development of land therein shall be carried out. ‘Existing Land Use (ELU) map’ is pre-requisite for Development Plan. ELU map means a map indicating the use to which lands in any specified area are put at the time of preparing the map. It is the Existing Land Use (ELU), preparation of which is a challenge and is certainly very crucial because it needs utmost precision in representing the true picture of the ground as existing on the day of its preparation. Lacunae in ELU map can jeopardize the proposed land use plan (that eventually becomes Development Plan). Also the time available for this activity is bound by the Act. Therefore, it is essential to adopt technologies that deliver precise data swiftly Existing Land Use (ELU) map is prepared by carrying out a survey of the lands within the jurisdiction of the Planning Authority and preparing a map indicating the existing use of land therein within the specified time. Ingredients of an ELU map are latest basemap depicting transport network, water bodies, structures, compounds & fences, etc. superimposed with revenue parcels (namely, survey parcels, city survey parcels, etc). The map is clubbed with the field information collected at structure level to define and depict usage of the land for each land parcel. Proposed Land Use (PLU) map is prepared after studying and analyzing the existing situation vis-à-vis the population projection for the horizon period (usually 20 years). Depicting the results of demand gap analysis is much easier in GIS environment as it allows the user in working out different scenarios and assess them individually as well as to compare them. Use of GIS in preparation of Existing Land Use (ELU) and Proposed Land Use (PLU) maps benefits in multiple ways. The first and foremost is that it gives digital data that is easy to handle, store, manipulate and update. Data representation is very powerful with GIS, a great variety of maps can be generated in very less time. GIS enables easy integration of data from various sources. Challenges faced during superimposition of revenue maps and generating seamless mosaic are better addressed with GIS rather than manual techniques. Various types of queries and analyses that can be done in GIS are otherwise difficult or sometimes, even not feasible with manual techniques. Preparation of Development Plan is a considerably long process and it involves mapping at different levels, right from first stage till the last. Therefore the data is voluminous and it undergoes multiple iterations of modifications. Data of each stages needs to be stores and analysed separately and comparison of data of different stages is also required. GIS is a tool that addresses this successfully and efficiently. Xenolith Geoservices is proud to be a pioneer and trend setter in the Maharastra State for preparation of Existing Land Use (ELU) and Proposed Land Use (PLU) as part of Development Plan procedure. Use of drone technology for preparation of ELU maps has further enhanced ELU map quality and reduced delivery time. Xenolith Geoservices has successfully mapped more than 60 towns in the State and recently it mapped 74 villages along Mumbai Pune Expressway (area under newly formed Special Planning Authority, MSRDC).
GIS for Property Tax management
  • India follows a three-tier governance system comprising of Central government, State Government and Urban Local Bodies (ULBs). India is one of the fastest developing nations in the world. To complement the economic growth of the nation with infrastructure development, the Government of India spelled national missions namely Jawaharlal Nehru National Urban Renewal Mission (JNNURM) and Urban Infrastructure Development Scheme for Small and Medium Towns (UIDSSMT). These missions clearly mentioned implementation of GIS for property tax management, implementation of MIS and double entry accounting systems as mandatory reforms to be adopted by the ULBs. Till date, Property Tax stands as the biggest source of revenue for ULBs. Property Tax in most of the Indian states is based upon the location of the property, its area and construction type, age and the usage (commercial, residential etc) of the property. Conventionally, majority of the ULBs have old records for the properties within the municipal council limit registered with them. However, the records are in paper form and are not updated since long. Over the period of time, the urban landscape at most of the places have transformed considerably. Many new properties come into being every year, but they are not necessarily listed with the ULBs. At times, the listed properties undergo change in construction or change in property usage, but this does not get reflected in the ULB records as the owners do not necessarily report them to ULBs. As a consequence, the ULBs remain unaware of ‘un-assessed’ and ‘under-assessed’ properties that can potentially add to the revenue. GIS based property tax management involves detailed mapping of the town/city under consideration along with very detailed property data collection. The difference between conventional practice of property tax management (manual) and GIS based property tax management is that the property information is integrated with the map which is much efficient way of handling such mammoth information. Data being in digital form, can be updated easily and computation of tax, generation of demand notices, bills, tax register and tax receipts is much easier. Comparison with the old/available property data of ULB with the latest information to identify the gaps is attainable and hence the system is popular. Linking of online payment gateways to property tax is feasible with the digital data and it has increased tax recovery. To improve the tax recovery, many of the ULBs are adopting modern ways such as mobile based applications for on-site recovery. In Maharashtra State, property tax revision takes place every fourth year. If the base data of any ULB is available in GIS form, its revision for the next cycle naturally would be much easier. Xenolith Geoservices has successfully completed more than eight assignments of GIS based property tax management
GIS for election maps
  • Election Commission, Maharashtra State issued guidelines in 2015 for preparation of Google Earth based election maps of Urban Local Bodies in Maharashtra. These maps depict Census Enumeration Blocks (EBs) and election wards formed by grouping EBs as per specified population criteria. Similar guidelines were issued for preparation of Zila Parishad, Panchayat Samiti and Gram Panchayat elections. GIS & Google Earth mapping for the said elections has given great deal of comfort to the respective officials because the maps so prepared are not just sketches but they are verifiable with actual ground conditions. It is observed that the use of high-resolution images as backdrop has reduced number of Objections received from the public. Xenolith Geoservices has mapped entire Pune district for Zila Parishad & Panchayat Samiti (2017 elections) as well as for Gram Panchayat elections (2018-2019) and many ULBs across the State.
Preparation of Annual Statement of Rates (ASR) using GIS
  • In Indian governance system, Department of Registration in any of the Indian States is one of the most important revenue sources. Collection of tax through Stamp Duty began in 1815 in Mumbai. Registration came into force in India in 1908. In Maharashtra a new department was formed in 1988 by merging Registration Department and Stamps Department. This new unified Department of Registration and Stamps started functioning under control of Inspector General of Registration and Controller of Stamps. Among the variety of registration, the highest stamp duty is generated through registration of immovable properties in the State. To increase the revenue collection of the department and to significantly contribute in the development of the State, the Department undertook new activities such as streamlining of stamp duty rates from time to time, conceptualization of Market Value and implementation of Annual Statement of Rates (ASR). The Bombay Stamp (Determination of True Market Value of Property), Rules,1995 prescribe procedure for preparation of ASR (formerly known as Ready Reckoner) which are required to be published annually. The mission of the department is to effectively use modern technology to provide services of document registration and collection of stamp duty to the people using well-defined procedures, with right means, in specific time frame and the transparent manner. Application of Geographic Information System (GIS) in the preparation of ASR for determination of true market value of property on scientific basis was attempted on pilot basis for part of Pune city. A web based application was developed by Xenolith Geosevices to display the basemap (roads, buildings, revenue parcels, etc)& ASR value zones and to show the ASR value for the selected property along with applicable discounts, if any, as per valuation guidelines.
GIS based mapping of town for Census Operations
  • In Census 2011, application of GIS for Census Operations was attempted on pilot basis in selected cities in some of the Indian states. In Maharashtra, it was attempted for Mumbai city. We undertook updation of digital map of Mumbai city as per the field survey maps followed by integration of census data. Maps were prepared for individual wards (24), sections & circles of Mumbai.
Google Earth based Heritage Information System
  • Heritage refers to something which is inherited from one's ancestors. Heritage places may have any of the following nature -Historical heritage, a nation or group's historic monuments, museum collections, etc. -Natural heritage, a nation's fauna and flora, natural resources, and landscape -Industrial Heritage, the monuments from the industrial culture The archive of heritage places in Pune was available with Pune Municipal Corporation in the form of album and folder with name and hard copy photograph(s) of the every individual heritage place. As the limitations of the paper documents are well known, the imperative need of a digital system to store and maintain this data was strongly felt. Xenolith Geoservices developed a user-friendly application based on Google Earth to be used by authorised personnel of the Municipal Corporation.
Web application for collection, updation& retrieval of rainfall data
  • A web enabled application was developed for collection of daily rainfall data via SMS from more than 400 rain guage stations spread across Aurangabad Division in Maharashtra State. Data so received was collated in a central server and was displayed onto web portal. The said application performed data analysis as specified and populated the result onto the web site.
GIS, GPS based school mapping for WASH
  • Following WASH (Water, Sanitation & Hygiene) guidelines spelled by Unicef, Kirloskar Consultants undertook detailed survey of Government schools within Pune city for the purpose of assessing drinking water and sanitation facilities in them, as a project for Kirloskar Foundation. We carried out GPS surveying and digital photography of these schools, government hospitals, some landmarks and volunteers’ locations. These locations were then plotted on electoral ward maps of the city and the attribute information (collected by MRFS division) with the digital photographs were integrated to them. A variety of thematic maps were prepared to depict the status of facilities in the schools spread across the city.
GIS based village maps for agro application
  • Thomson Reuters is one of the leading, globally recognized organization for providing informational services in financial, healthcare, media, legal, tax & accounting etc. It is also providing weather related information for various states in India. Xenolith Geoservices provided them village level maps with their weather stations mapped on them, for two districts in Maharashtra State. Further, we also provided taluka level maps for five States in India. These were utilized in agro based application developed by Reuters
Pre-feasibility survey of airport
  • This project involved carrying out DGPS survey of the existing and proposed runway and apron followed by its mapping onto high resolution satellite image, Survey of India toposheet and superimposition of revenue parcels. Weather data was also collected (rainfall & wind) for the specified period.
Accident analysis of Mumbai Pune Expressway
  • Accident Analysis Project was executed for 10 km accident-prone zone (Km. 73 –83) of Mumbai Pune Expressway. Accident Database including location, time, cause and type of vehicle involved in the accident was projected on digital map of the stretch. Temporal as well as spatial distribution of accident spots was studied using GIS techniques and the results were depicted to show the spatial pattern.
GIS based Pollution Hazard Zone mapping
  • Pollution monitoring project was executed for Pimpri-Chinchwad area. This project included preparation of Pollution Hazard Zonation map (air, water, noise and soil) of PCMC area using satellite images, data collected from the field and analyzing data using GIS tools and techniques.
Mapping of the effects of possible cyclonic storms
  • Project aimed at assessment and mapping of the effects of possible cyclonic storms along the West Coast area of Maharashtra. (Included detailed field study of 300 sq km coastal area). The project involved prediction of the risk of any such eventuality to human life, property, and the environment. This project facilitated disaster managers to quickly assess and display critical information spatially.
Restoration, Conservation and Management Plan for lakes
  • Following the guidelines for National Lake Conservation Plan (NLCP) this project was carried out for two lakes located in the famous pilgrim in Maharashtra. There are two manmade lakes of historic times and out of two, one was then completely dried up whereas the other had deteriorated a lot. The project thus aimed at the study of the current status of the lakes including its catchment water quality & water holding capacity and to suggest restoration, conservation & management plan.
Land use land cover (LULC) mapping using satellite images
  • Land use land cover (LULC) map refers to thematic map showing patches of land user water bodies, vegetation, cultivation, habitation, etc. Land use land cover mapping is done using False Colour Composite (FCC). Terms of References (TOR) issued by Ministry of Environment & Forest (MoEF), Government of India for environmental Impact Assessment (EIA) study mentions ‘Land use land cover mapping using satellite images’ as an integral part. We have conducted land use land cover mapping pertaining to EIA study of proposed thermal power plants, SEZ, reservoir, mining lease, national highway, townships, etc.
Landscape change detection study of Mahabaleshwar Panchgani Eco Sensitive Zone (ESZ), Maharashtra
  • Mahabaleshwar, Panchgani Eco Sensitive Zone (ESZ) is a government notified area-admeasuring area of 236 sq km. Land use land cover mapping was carried out using the satellite images of the study region for the years 1989, 2001& 2011. This region comprised of 60 villages.
    Land use land cover & NDVI analysis were carried out and it was observed that degradation of forests is mainly in the form of changing vegetation composition, alternation in vegetation community structure and conversion of landuse elements. Comparatively more changes in landuse were observed in 2nd decade than the 1st decade, which highlighted increased anthropogenic activities as one lead cause of change in the landscape.
