NILS GeoCommunicator provides the following Web Services: Find and Derive Land Description (LD), and Survey Exporter. The Web Services are provided on GeoCommunicator or they can be developed within other applications using the web services. The web services can be used in your applications that consume these web services using protocols such as SOAP and GeoRSS. The Web Service uses the National Integrated Land System's (NILS) survey-based and non survey-based land descriptions. The land descriptions are in NAD83 Geographic. We provide an XML of the services and you develop the interface and connection to the service for your application. On GeoCommunicator we have developed several tools that use these services as describe below. These tools are available in many of our map viewers.

Find Land Description (Find LD): Find LD provides the ability to pass a land description (state, meridian, township, range, section, aliquot) and have the latitude and longitude returned for the coordinates defining the boundary of the shape. The coordinates can be used to draw the area on a map.

Derive Land Description (Derive LD): Derive LD provides the ability pass the coordinates (latitude and longitude) of a shape (polygon) and have the land description (state,meridian, township, range, section, aliquot, lot) returned.

Survey Exporter: (Coming Soon) Will allow you to export points, points and lines, or control points for the Public Land Survey System (PLSS) data (township, range, section, aliquot) in NILS geocommunicator. The exporter provides the ability to export the data in KML, GPX, list, and GeoRSS formats.
