VISIONLABS has come out with a completely indigenously developed Suite of Software Packages titled 'VISION LIS 2000' to meet this requirement. This suite comprises of:
1. Background 1.1. Land Management Land is the most basic and precious resource to mankind. Indian villages are typically a geographic tract of land with hundreds of acres of arable and wasteland. Ownership of land is perhaps as ancient a concept as the Indian Tribal Settlements and has held paramount significance throughout history. Land Management is a key focus area for revenue departments throughout the country. The Government of India has laid a major emphasis in the last decade on land reforms and modernization of land records. A Land Information System, is essentially a computerization process which assists in the conventional stages of land records system, namely,
1.2. Need for computerization Importance of Land Records
Preservation
The objective of cadastral survey is the determination of village and field boundaries, preparation of village map showing such boundaries and area lists, and preparation of field registers. The map and area lists give the physical boundaries and areas and the field registers give the land particulars like ownership, revenue assessment, land classification etc. Numerous survey methods were used in the 19th and 20th Century. Many of these systems led to inaccuracies and were modified time and again. However, the Bombay Survey System and Madras Survey System records, which evolved after 1880, were highly accurate and were directly or with variations adopted as a standard in many States. Bombay Survey System This method involved running an imaginary line called G-Line or Baseline across the field and measurement of plot boundary vertex locations with respect to this line. Two distances, the distance along the baseline and the perpendicular length from the baseline to the vertex were recorded in the form of a Ladder Table or Field Measurement Table (FMT). The Field Data for a village were maintained in a book with the ladder tables and a rough or fair sketch of each land holding. Variations of this method include use of multiple baselines, adharline survey (where a number of plots were surveyed on a single long baseline, with the entire village surveyed on 1 to 4 baselines), punganur system (where entire village was surveyed on one baseline) etc. Madras Survey System This method involved dividing plots into triangles and recording the length of each side of the triangle. However, variations were used to include some points recorded as offsets from a triangulation line. 1.4. Mapping Village maps were prepared by using the individual survey fields data. Such maps tended to be slightly inaccurate due to error in individual fields being migrated across the village. Errors generally crept in due to measurement resolution being rounded off and also due to non-planar nature of the ground. Field sketches assume the ground to be flat, however, the same data when migrated across a village result in some error. One important method used to reduce the error was traverse survey. In traverse survey, the entire village was divided into one or more blocks and known ground points (called traverse stations) in each block were surveyed. The method involved starting from one location and recording distance and angle to the next station and so on till the circuit was closed. This circuit represented an accurate block boundary, whereby plots belonging to that block were manually adjusted in the map to fit into the traverse circuit. In Southern States, changes made to any plot boundary in the process of village traverse fitting were not reflected back on the original Field Data, i.e., only the original record of field measurement table or sketch is legally acceptable. However, in many northern states, the individual field records were either lost or abandoned after preparation of accurate village map and this map became a basis for obtaining individual survey boundaries. Survey of India has utilized the village maps to obtain higher level maps like mandal/taluka, District, State etc. 1.5. Spatial Analysis Applications Maps are a powerful medium for planning, analysis and monitoring for a large number of applications. Satellite images, Cadastral Maps, Political Boundaries, Contours, Networks and Locational Analysis are handled on a day-to-day basis by decision-makers in numerous organizations. The data of cadastral survey form the basis for generation of any accurate higher level map. Spatial analysis applications are of two types: Micro level planning and development Micro level planning generally involves ground study and evaluation of data of a specific area of interest. For e.g., Rural Development Schemes, Irrigation, Ground Water Development, Town Planning, Mining etc. require a study of maps and data pertaining to small zones. Macro level planning and development Macro level planning generally involves study and evaluation of data of a large geographic zone. For e.g., Statewide policies, Excise, Fiscal Analysis etc. are macro level applications. Spatial Analysis Applications, especially in micro level, are a natural progression from Land Management applications, as the maps are directly used or derived from cadastral survey data and the land profile and usage information is available in land registers. 2. VISION LIS 2000 2.1. The concept of LIS An LIS forms the micro-level land management tool. In contrast, Geographic Information Systems are a macro-level tool for decision-making applications. In some applications, GIS spatial/logical database is an assimilation of an LIS database. Most Government as well as private organizational applications are pertaining to management of spatially distributed data. In this context, a GIS based management approach has gained increasing acceptance globally, and is now also being adopted in India in many organizations. LIS and GIS can work hand-in-glove for effective management and in many applications, they are the only viable and appropriate solutions for effective data management and analysis. The concept of Land Information System Computerized storage, retrieval and analysis techniques are the universally accepted methodology for numerous information management applications. An LIS is a computer-based solution for addressing the requirements of Land Records Management System. It attempts to preserve, maintain and analyze records in computer form accruing in the numerous benefits associated with this technology. 2.2. Indigenous technology solution VISIONLABS, a pioneer in indigenous software development in Scientific and Engineering applications, has developed an LIS software solution VISION LIS 2000, to meet every requirement of Land Records Management and also looks beyond into the future of Land Management. The complete software is tailor made for Land Management application and complete source level support is available. The development is a product of 5 years of meticulous research, which involved interactions with many senior experienced officers involved in Land Management portfolios, Central Survey Office, numerous State Land Records Departments and analysis and testing by various Surveyors and field executives. VISION LIS 2000 is the product of over 200 man-years of coordinated effort put in by Software Engineers, Surveyors and User Departments. 2.3.

4. VISION LIS 2000 - No competition! 4.1. How it compares with other LIS lookalikes VISION LIS is the only product totally designed, developed and customized for the specific application. Most of the other products available in the market are GIS software (like ArcInfo), CAD overlays (like AutoMap) or overlays/customization of GIS or CAD (like SICADLand). Other software are not true Land Information Systems, in the sense that they lack certain fundamental features required for LIS applications (and also lack many advanced LIS features). VISION LIS meets 100% of the Land Information Management requirements, and has source level support being an indigenous product. A comparison of some of the software vis a vis features essential for LIS and also advanced features to cater to future survey and land management needs makes it very obvious that VISION LIS 2000 has no competition! Another important issue is the suitability of the LIS software across the nation, i.e., whether it is useful and tested for the numerous survey and records management techniques adopted in different states. The comparison confirms that VISION LIS 2000 meets all national needs. 4.2. Unique Product Features - Summary In summary
VISION LIS 2000 IS THE MOST VERSATILE AND WIDELY ACCEPTED LAND INFORMATION SYSTEM ACROSS THE COUNTRY 5. Conclusion In conclusion, we are presenting below the various products and services offered by VISIONLABS 5.1 Products VISION LIS 2000 consisting of:
