System and method for dynamically retrieving data specific to a region of a layer

摘要

A system may provide for retrieving data within a selected region of a map is provided. The system may include mobile devices configured to display a map and to receive a user selection of a region of the map. An application server may receive data from the mobile device, representing the user selected region of the map and a search criterion. A database may be in operative communication with the application server and executes a query using the data representing the selected region of the map and the search criterion and to return data results corresponding to a plurality of locations within the selected region and related to the search criterion. The mobile device may further be configured to display the data results corresponding to the plurality of locations on the selected region of the map and the displayed data results are automatically updated when the user moves the selected region of the map.

1. A system for retrieving data within a selected region of a layer, the system comprising:
an application server comprising at least one processor and at least one memory, the application server configured to:
receive data from a user device representing a user selected region of a selector tool corresponding to a layer and a search criterion, wherein the user selected region of the selector tool has a first scale and the layer has a second scale;query a database in operative communication with the application server for at least one location within the layer related to the search criterion and the user selected region of the selector tool, the query including the data representing the user selected region and the search criterion;receive, from the database, at least one data result corresponding to the at least one location within the user selected region and related to the search criterion;provide the at least one data result to the user device;receive updated data from the user device representing a user-initiated change of the second scale of the layer;automatically change the first scale of the user selected region of the selector tool proportionally to the change of the second scale of the layer to define an updated region of the selector tool;query the database for at least one updated location within the layer related to the search criterion and the updated region of the selector tool;receive, from the database, the at least one updated data result corresponding to the at least one updated location; andprovide the at least one updated data result to the user device.
