Methods, including computer programs encoded on a computer storage medium, for determining whether a spatial record is located within a polygon. In one aspect, a method includes: receiving data identifying a polygon positions on a coordinate system, identifying a plurality of lines to represent the polygon, accessing information that identifies a spatial record position at a location on the coordinate system using a spatial index that includes spatial data and non-spatial data, generating a ray that emanates from the spatial record and that is projected in a particular direction, determining whether the spatial record is located within the polygon based on a number of times that the ray intersects the plurality of lines, and outputting information that identifies whether the spatial record is located within the polygon.

The present invention provides an apparatus and method for generating title products. A device accepts a title product search request for a title product for a property. The device initiates a search of databases that contain information about the property such as data or evidence of title. A rule engine compares the retrieved information with business rules such as title insurance underwriting criteria. The comparison provides results for generating a title report, insurance contract or other title insurance products.

Swimming pools can be visualized according to some aspects described herein. In one example, a system can receive a user selection of a particular liner from among a plurality of liner options for a virtual swimming pool. The system can generate a virtual swimming pool having the particular liner. The virtual swimming pool can be a three-dimensional (3D) rendering of a swimming pool with the particular liner. The system can then output the virtual swimming pool for display on a display device.

The invention provides a secure method for exchanging entities via a blockchain. The invention incorporates tokenisation techniques, and also techniques for embedding metadata in a redeem script of a blockchain transaction. Embodiment(s) provide a method of: generating a first script, the first script comprising: a first set of metadata associated with a first invitation for the exchange of a first entity by a first user, the first set of metadata comprising an indication of the first entity to be offered for exchange and a first location condition for the exchange, a first user public key (P1A) associated with the first user, wherein the first user public key (P1A) is part of an asymmetric cryptographic pair comprising the first user public key (P1A) and a first user private key (V1A). The script may further comprise and a first third-party public key (P1T) associated with a first third-party, wherein the first third-party public key (P1T) is part of an asymmetric cryptographic pair comprising the first third-party public key (P1T) and a first third-party private key (V1T) The method further comprises the steps of hashing the first script to generate a first script hash and publishing the first script and the first script hash on a distributed hash table (DHT).

This invention relates to an information management system of lawn profile data. It comprises a lawn profile information collecting tool for collecting information any pieces of lawns that need mowing jobs; wherein the lawn profile information collecting tool includes a data converter for converting such information to lawn profile data, and data processer for processing the lawn profile data locally into suitable formats and categories for uploading; a mobile device of a user being in communication with the lawn profile information collecting tool to receive the processed lawn profile data; a remote information processing center being in communication with the mobile device and the lawn profile information collecting tool to receive and process requests from the mobile device to upload the lawn profile data; wherein the remote information processing center includes a data storage unit for storing the lawn profile data for usage thereof by a designated lawn mower to perform mowing job, that is, using the stored lawn profile data associated with the particular piece of lawn as requested.

Systems and methods for three-dimensional computer modeling of buildings are disclosed, including a method comprising generating, with a computer processor, a 3D model of walls of a structure and a wall area measurement estimate report, using the 3D model of the walls, displaying multiple line drawings of a building having a roof.
