B. Background Art:
The digital world is enabled by a number of interconnected systems, acting as a key facilitator of collection, processing and communication of information datasets. As the world is beginning to reject systems that create silos or force inefficient workflows, interconnected systems are the key to making disparate solutions fit the customer workflow rather than the other way around.
In the digital era, geospatial technologies are revolutionizing the economy. Geospatial data is most useful when it can be discovered, shared, and used. Across the globe various initiatives are taken to establish infrastructure and regulate storage and usage of the spatial information.
The Infrastructure for Spatial Information in the European Community (INSPIRE) is one of the initiatives by EU to establish an infrastructure for spatial information in Europe that is geared to help to make spatial or geographical information more accessible and interoperable for a wide range of purposes supporting sustainable development. The INSPIRE Geoportal is the central European access point to the data provided by EU Member States and several EFTA countries under the INSPIRE Directive. The Geoportal allows monitoring the availability of INSPIRE data sets, discovering suitable data sets based on their descriptions (metadata), accessing the selected data sets through their view or download services. The

metadata used in the Geoportal are regularly harvested/indexed from the discovery services of EU Member States and EFTA countries.
The one of the other initiatives is 'Federated database system'. The federated database system is a type of meta-database management system (DBMS), which transparently maps multiple autonomous database systems into a single federated database. The constituent databases are interconnected via a computer network and are be geographically decentralized.
US 20170329801 discloses Systems and methods for storing and retrieving geospatial data in a geographic information system. Geospatial data can be spatially partitioned along axes of a spherical coordinate system associated with a virtual globe or other spheroid into a plurality of discrete geospatial volumes pursuant to a hierarchical spatial partitioning scheme. For instance, geospatial data can be spatially partitioned into geospatial volumes along surfaces of constant latitude, longitude, and altitude defined by the spherical coordinate system. The discrete geospatial volumes can be stored as nodes in a hierarchical tree data structure. Additional methods are provided for portioning geospatial objects, such as tiles or discrete geospatial volumes, in tritree to reduce polar distortions.
US 8799074 discloses Methods and apparatus for cataloguing items such as maps and geospatial data sets store in a database information defining a geospatial region corresponding to each item and a size characteristic of the geospatial area. The database may be queried to identify items of interest by intersecting a search seed comprising one or more geospatial points, lines or areas with the areas corresponding to the items. A result set containing items produced by a query may be ordered at least in part according to the size characteristics. In some embodiments the size characteristics comprise square roots of the areas of the geospatial regions.
US 20150088853 A geospatial search portal, systems including the same, and methods of making and using the geospatial search portal are disclosed. The geospatial search portal generally includes an electronic information harvester, a

tagger, metadata analysis logic, an electronic map having a plurality of electronic locations thereon, and a processor. The electronic information harvester seeks and retrieves relevant scholarly, technical, encyclopedic, factual and/or archival information. The tagger associates a plurality of georeferences and a plurality of metadata to each item of information. The metadata analysis logic analyzes the metadata and organizes the metadata into index terms and/or map symbols, and may comprise an indexer and a depictor. The processor is configured to display at least some of the associated information on the electronic map and/or in a textbox when the electronic location(s) on the electronic map, the georeference(s), and/or the metadata is/are electronically selected.
In US 8650220 Systems and methods for storing and retrieving geospatial data in a geographic information system are provided. Geospatial data can be spatially partitioned along axes of a spherical coordinate system associated with a virtual globe or other spheroid into a plurality of discrete geospatial volumes pursuant to a hierarchical spatial partitioning scheme. For instance, geospatial data can be spatially partitioned into geospatial volumes along surfaces of constant latitude, longitude, and altitude defined by the spherical coordinate system. The discrete geospatial volumes can be stored as nodes in a hierarchical tree data structure. Additional methods are provided for portioning geospatial objects, such as tiles or discrete geospatial volumes, in tritree to reduce polar distortions.
While these data security systems and method thereof exist, the nature of the system is such that all the data and metadata must be stored in one system/registry. There is no support for running a query on multiple distributed registries. Since all the spatial data must be stored in a central place, the owners of the data don't have control over how the data is accessed and managed in the central system.
In a situation where there are a number of registries and spatial data is spread across multiple registries, searching and retrieving geospatial information is

challenging due to the fact that all registries need to be searched to retrieve the relevant geospatial information.
Geospatial Analysis can be performed on spatial data using SQL queries, but they are limited to a particular database instance only. Databases by themselves are inadequate to perform geospatial analysis on spatial datasets residing in other databases.
Although spatial data can be copied from a remote database system to a local database system, it may not always be feasible due to the huge size of the spatial datasets, access restrictions on the remote or local databases or other such reasons. In case of multiple databases, it may be even more difficult to retrieve relevant information pertaining to the geospatial analysis that is to be performed.
Therefore, there is need of a system and method thereof that minimizes the number of registries that need to be traversed to search for the relevant geospatial information.
Therefore, there is a need of a system and method thereof that alleviates the need to query those registries and spatial databases which do not have the desired geospatial information relevant to the search filters by using a Registry Search System.
Further, there is a need of a system and method thereof that reduces the time taken to perform a search operation and in turn minimizes the network traffic and bandwidth required to perform a search operation and increases the throughput of search results.
For the reasons stated above, which will become apparent to those skilled in the art upon reading and understanding the specification, there is a need in the art for a system and method for information retrieval, an automated method and system for searching and retrieval of geospatial information from multiple distributed or federated spatial registries that can intelligently search information from multiple

registries and efficiently retrieve relevant geospatial information from multiple databases to reduce the time taken to perform geospatial analysis and produce more relevant results. The automated method and system for searching and retrieval of geospatial information shall be useable, scalable and independent of new technology platforms, uses minimum resources that is easy and cost effectively maintained and is portable and can be deployed anywhere in very little time.

The present invention is further described through the figures 1 to 4.
Figure 1 illustrates the logical structure of storing spatial data and its metadata in multiple databases and registries, according to an exemplary implementation of the present invention. As depicted in the figure a table is the fundamental unit of storing data in a relational database. A spatial database stores spatial data together with non-spatial data across multiple tables. A registry is comprising of a plurality of theme records of a plurality of codelist, a plurality of application schema of a plurality of registers and a plurality of respective metadata records. A registry is a document oriented database, or a document store where data is stored in the form of documents (also called records). Every table in the database has its metadata stored in the Registry in the form of metadata documents also called metadata Records. Codelists are the documents that contain all possible name unique values of a conceptual object. For example, types of shapes (Circle, Square, Triangle etc.), types of Soil (Sandy, Clay, Silt, etc.)
Figure 2 illustrates a mechanism that the Registry search module undertakes to gather all the registers/ codelists contained in all the registries connected to itself in the system, according to an exemplary implementation of the present invention. The registry search module (104) undertakes to gather all the codelists contained in all the registries connected to itself in the system, and maintains its own registers which contain codelist values and maps it to the registries that have those

values (see 101 and 102). As depicted in the figure the registry search module (104) enables searching multiple registries based on the metadata records and registers/ codelists stored in those registries to retrieve relevant information. The registry search module (104) maintains a de-deduplicated copy of all the registers/ codelists stored across all the registries in the system and an internal map to map the individual values back to the individual registries. Further, the registry search module (104) accept keywords (105) along with a set of filters (106) such as but not limited to theme, application scheme etc. A search filter (106) contains the name of the codelist and the target values to be searched against (e.g. match all records in which TypeOfSoil == Clay). The registry search module (104) determines the relevant registries to be searched based on the criteria provided in the search request. The Registry search module (104) looks up in its internal map and decides which registries to forward the search request to, thereby eliminating the need to search registries which are not relevant according to the search filters.
Figure 3 illustrates an intelligent searching mechanism, according to an exemplary implementation of the present invention. As depicted in the figure all the search parameters are analysed by the registry search module and the search query is forwarded only to those registries which have the same codelist values as contained in the search parameter. As illustrated in the figure a SearchRequestObject encapsulates the search keywords and the search filters. The SearchResultObject also encapsulates the search results. The registry search module depicted in the figure intelligently forwards the search request only to those registries which relevant data related to the filters contained in the SearchRequestObj ect.
Figure 4 illustrates a process followed for retrieving relevant geospatial data for a search query, according to an exemplary implementation of the present invention. As depicted in the figure the functional flow for retrieving relevant geospatial data for a search query starts at the registry search module, analyzing the SearchRequestObject and comparing each filter with its internal map of codelist values and the registries that contain them. As a next step of the flow for

retrieving relevant geospatial data for a search query the registry search module determines the relevant registries which contain data related to the search filters and then forward the SearchRequestObject to those registries only. As a next step of the flow for retrieving relevant geospatial data for a search query the relevant registries perform the search in their own registry database and then return the search results to the registry search module. As a final step of the flow for retrieving relevant geospatial data for a search query the registry search module aggregates the search results retrieved by the individual registries and provides them to the user.
The present invention as implemented through various embodiments is economically viable and can be adopted by the businesses easily as it provides the higher graded security in economical plans.
Advantage of the present invention according to one and all embodiments are:
Spatial data and its metadata can be stored in a distributed system without the need to compile everything in one system.
Federated search across multiple registries reduces the time taken to search for relevant data and metadata.
Owners of spatial data have complete control over the management and access to their data.
The present invention allows multiple types of metadata schema to be automatically ingested, indexed and queried from remote sources. It is unique in its implementation of the Bureau of Indian Standards (BIS) standard: "BIS-16439: 2016 (reaffirmed 2019) Metadata standard for geospatial information".
