Abstract – In India, Cadastre represents a land parcel which reflects the entitlement of land holding , area of the land and landuse of that land parcel. In cities or in alignment of road on goverment/ privite land, encroachment/ unauthorized construction has become a common practice by people in our country. Therefore taking quantative information, like area and extent from these maps may sometimes give enormous information about the land holdings. Most importantly, acquiring the land and making a landuse plan for housing scheme requires the accurate information related to encroachment, keeping in view the objective of providing accurate information on encroachment at plot level, World View satellites 50 cm resolution data was used in present study. The study has been carried out in five villages in alignment/both side of Delhi-Saharanpur road housing scheme of Uttar Pradesh Housing Board, Ghaziabad, India. The study area covers 12.50 sq km, where housing scheme is proposed. It has been found that there is a lot of encroachment at various plot, which has been acquired by

U.P. Housing Board, Ghaziabad for development of resedential colony.

INTRODUCTION

In India, Uttar Pradesh is the most populous state. Which is having 724 urban local bodies i.e. Nagar Panchayat / Nagarpalika Parishad / municipal corporations including cantonment board & industrial township and around 2.71 lakhs of villages as per Census of India, 2011, with 19.91 crore of total population. Various cities/ towns of the state have achieved the status of first class towns/ cities in the recent years and 7933 cities are reported in our country accordingly. (Kumar, V. 2012). Due to excessive pressure of population, rapid urbanization took place and as resultant, numbers of colonies has been developed by development authorities. These colonies has been taken up by urban local bodies as a resultant the urban density of the

state is now reported around 4937, where the average density of the state is 473 person per sq. km, and there is an increased need of housing in cities. In this context to fulfill the housing need, the role of urban planning agencies is becoming increasingly more complex and extending to a wider range of activities, thats why urban development authorities are acquiring land for development of colonies. (Gopalan, A.K.S. 2009), fine spatial resolution allows small objects to be seen and mapped, special choice of spectral bands enhances the discriminating ability between the land covers. Over the years satellite based remote sensing data have been successfully utilized for identification, mapping and monitoring of encroachment in conjunction with cadastral maps, Geographical Information System (GIS) and Global Positioning System (GPS). (Rao & Shekhar, 2000), In India, cadastre is the basic unit to provide plot wise reliable information regarding land holding/land revenue system. But unfortunately these cadastre are often quite old (above thirty years old) and still maintained on paper or cloth. Geo-referencing and overlaying of these cadastre on high resolution data can provide the accurate information on encroachment/unauthorized construction at each and every land holding. The present paper is an endeavor to analyze the plot wise encroachment/built-up area at Delhi- Saharanpur Road Housing Scheme of Housing Development Board, Ghaziabad, Uttar Pradesh, India. The digital database generated for the study area would be very useful for urban planners/decision makers for proper land use planning and management.

OBJECTIVES

The objective of the present study is identification and mapping of encroachment/unauthorized construction at proposed housing scheme of Delhi-Saharanpur Road of Awas Vikas Parishad, Ghaziabad, Uttar Pradesh India using high resolution remote sensing data cadastral maps,

Geographical Information System (GIS) and Global Positioning System (GPS) Techniques.

STUDY AREA Ghaziabad city is located in Western part of Uttar Pradesh the area lies between latitude 2804659.06N to 280502.196 N and longitude 770 1444.513E to 770 1728 E. (Fig.1).Which is spread over an area of 12.5 sq km approximately. The city is well connected rail/road transportation system with all parts/ cites of India due to nearest city point with New Delhi, the national capital of India. The study area also comes under national capital Region on Delhi- Saharanpur road. The present study has been taken for five villages (i.e Mandola, Panchlok,Milak,Bamla and Nanu), which are in both sides of delhi-Sarahnpur road near New Delhi.

  METHODOLOGY

  The procedure followed for identification and mapping of encroachment area on 1:1,000 scales and for preparation of digital database using remote sensing and GIS techniques is discussed in brief as under:

  The Delhi-Saharanpur Road Scheme area acquired by U.P. Awas Vikas Parishad Ghaziabad is mapped in this project

  using remote sensing & Geographical Information System (GIS) and Global Positioning System-Mobile Mapper Field & Office Software (GPS). This project work is carried out to prepare detailed information for mapping and monitoring the encroachment at plot level of the study area. Cadastral map of the area collected from sponsoring department, it was geo-referenced in conjunction with Worldviews satellite data in GIS environment. After geo- referencing of cadastral map, all available/collected maps were corrected and geo-referenced to real earth coordinates and the same projection of Universe Transverse Mercator (UTM) and World Geodetic System 84 (WGS_84) was given to each and every map. Cadastral map were also vectorized and digitized and attributes coding of each and every plots i.e. plot no. has been given. The road/transport- network/city major/minor roads/streets, railway line, water bodies, drainage/nala etc. were interpreted as a linear, polygon feature using Arc-GIS software and Worldview 50 cm. resolution data and village names and important locations were shown in base map. After preparation of base map, the cadastral map was overlaid on high resolution satellite data. Encroachment/unauthorized construction existing in plots of study area have been identified and demarcated using high resolution data in GIS domain. The cadastral maps overlaid on rectified data have also been further checked/verified on the ground for conducting field survey for collection of field information related to encroachment. A detailed ground truth verification/field survey has been carried out with the help of single frequency Global Postioning System- Mobile Mapper Field & Office Software (GPS) to know the exact location of unauthorized construction/land use with their actual extent. The individual polygons have been given attributes coding in GIS environment. After field survey of the study area through DGPS, the data collected in field, were converted into tabular format and they have been matched and linked with digitized maps in GIS domain for preparation of final map on 1:4,000/1:2,000 scales.

  RESULT AND DISCUSSIONS

  To create the digital database for Delhi-Saharanpur Road Scheme of Ghaziabad, Uttar Pradesh, India. Base map at cadastral level was prepared for generating information of each and every plot. High resolution 50cm. imagery of Worldview satellite (Pan plus Multispectral) data and SOI topographical map sheet no. 53H/5 on 1:50,000 scales have been used for identification, mapping of small features and ground truth/G.P.S has also been use for data collection purpose in study area. Base map showing road/transport- network, city major/minor roads, railways line, canal/distribution, river, drainage/nala, water bodies were digitized on 1:1,000 scale and the final land use maps has been used for field survey, composed on 1:4,000/1:2000 scale indicating total built up area indicating total built up area including village settlement area of 0.85 Sq Km and the area of power grid calculated as 0.47 Sq Km in GIS domain. In cadastral map, total 3032 plots/land holdings are digitized and attributes coded (Fig-2), out of which small encroached units are identified and mapped in 156 plots. The no of these plots and encroached/built up/

  unauthorized construction area has been shown in Table-1 indicating the land holding no. Fig-3 shows the all small land parcel overlaid on satellite data, which has been encroached by the people in study area. The encroached area in different plot has been calculated in GIS, and it is 231248.27 sq meter approximately. The entire study area is splitted into 6 parts to show the transparency in encroachment at each and every plot. Fig.4 to Fig.9 shows the study area into 6 parts (from 1 to part 6). Fig. 4 represents the part 1, Fig.5 and onwards is representing the study area map continuously from part-2 to 6, on which the cadastral map with plot no. has been overlaid on Worldview satellites 50cm spatial resolution data acquired in November, 2011. The land cost for residential/commercial/industrial and for other purposes/ land uses is very high due to coming this area under National Capital Region (NCR) New Delhi.

  RECOMMENDATIONS:

• Before acquisition of land for residential colony purpose by development authorities, prime agricultural land should be avoided and the culture of vertical city development is needed to fulfill the need of increased housing in urban periphery.

• Investigation of soils building load bearing capacity should be compulsory for all govt. /private construction companies to avoid the manmade disaster like land subsidence.

• Laws / standards of eco-city planning should be compulsory for all govt. /private builders.

  CONCLUSION

  The remotely sensed data, Geographical Information System (GIS) and Global Positioning System (GPS) has proved an effective tool in plot level rural/urban/cadastral mapping, monitoring and analysis. The spatial extent of various small construction units/encroachment identified and interpreted at plot level for the study area will be useful for planners and decision makers at micro level planning & management. Furthermore, the development of intelligent

  GIS with high resolution panchromatic & multispectral data of Quickbird, IKONOS, Worldview, Worldviw-3, Cartosat-1, Cartosat-2 & Geoeye may enable generating parcel level land use/ land cover inventories necessary for future/ sustainable development of land resource and may facilitate monitoring the input of implementation of suggested land use program in urban / rural area.
