Various methods, systems, and apparatus for implementing aspects of a digital mapping system are disclosed. One such method includes sending a location request from a client-side computing device to a map tile server, receiving a set of map tiles in response to the location request, assembling said received map tiles into a tile grid, aligning the tile grid relative to a clipping shape, and displaying the result as a map image. One apparatus according to aspects of the present invention includes means for sending a location request from a client-side computing device to a map tile server, means for receiving a set of map tiles in response to the location request, means for assembling said received map tiles into a tile grid, means for aligning the tile grid relative to a clipping shape, and means for displaying the result as a map image. Such an apparatus may further include direction control or zoom control objects as interactive overlays on the displayed map image, and may also include route or location overlays on the map image.

Digital mapping system

A system for ranking geospatial entities is described. In one embodiment, the system comprises an interface for receiving ranking data about a plurality of geospatial entities and an entity ranking module. The module uses a ranking mechanism to generate place ranks for the geospatial entities based on the ranking data. Ranked entity data generated by the entity ranking module is stored in a database. The entity ranking module may be configured to evaluate a plurality of diverse attributes to determine a total score for a geospatial entity. The entity ranking module may be configured to organize ranked entity data into placemark layers.

An electric traction vehicle is described herein which may be used to provide power to off-board electric power-consuming systems or devices. The electric traction vehicle may provide 250 kilowatts or more of three phase AC power to an off-board electric power consuming system. The electric traction vehicle may also include an electrical power storage device which can be selectively discharged to allow the vehicle to be serviced.

Digital tile-based mapping techniques are disclosed that enable efficient online serving of aesthetically pleasing maps. In one particular embodiment, an image tile-based digital mapping system is configured for generating map tiles during an offline session, and serving selected sets of those tiles to a client when requested. Also provided are solutions for handling map labels and other such features in a tile-based mapping system, such as when a map label crosses map tile boundaries. Various processing environments (e.g., servers or other computing devices) can be employed in the system.

Generating and serving tiles in a digital mapping system

One or more agricultural products, such as seed, fertilizer, herbicide and pesticide, may be dispensed at each of a plurality of row locations on an agricultural implement toolbar. A local bus connects each local metering device to a local controller at the row location, which may also have actual product application rate and soil characteristic sensors. The local controllers are connected through a system bus to a central processor mounted on the tractor, which is connected to a memory for storing product prescription and actual application maps, and also to a GPS receiver for determining current location in the field. Each local controller controls the agricultural product metering device(s) at the row location as a function of the last commanded rate received from the processor and the actual rate as sensed at the row location. The commanded rate may be derived by the processor as a function of multiple variables as stored in levels of the prescription map, or from a manual override signal from the operator.

A field mapping system for an agricultural vehicle such as a combine, planter or cultivator is disclosed herein. The system includes a circuit for determining the position of the vehicle relative to a field, and a sensor for sensing a characteristic (e.g., grain moisture content, grain harvest yield, soil compaction, altitude, etc.) at locations of the vehicle within the field. The system also includes an electronic display controlled by a control circuit coupled to the position determining circuit and the sensor. The control circuit produces display signals applied to the electronic display to generate a map of an area of the field at a desired scale which includes indicia of the current vehicle location and of the characteristic data being gathered. The map is dynamically redrawn at the desired scale to keep the visual indicia displayed when the vehicle has moved such that the vehicle location no longer corresponds to the displayed area.

A reconfigurable control unit (50) is disclosed for providing an operator interface (124) to control units on different types of work vehicles, such as, tractors, combines, sprayers, etc. The reconfigurable control unit stores a plurality of application programs in a memory and selects only the application program as needed depending on the work vehicle type that the reconfigurable control unit (50) is coupled to. The type of work vehicle to which the reconfigurable control unit (50) is coupled to is determined based upon a unique configuration message received from a controller on the work vehicle. The work vehicle type may also be determined by scanning a data bus connector (102) that couples the reconfigurable control unit (50) to the work vehicle, or by soliciting operator input to determine which type of work vehicle the reconfigurable unit (50) is coupled to.

Reconfigurable control unit for work vehicles

A control system for agricultural implements such as planters, conventional or air drills is disclosed herein The implement includes a frame with one or more sections Each section supports a plurality of row units configured to apply a product at variable rates to rows in a field The products can include seeds, fertilizers, insecticides and herbicides In one configuration, the control system monitors the rates at which the product is applied to the rows This configuration of the control system includes sensors configured to sense the rates at which product is applied, and a control module configured to monitor the sensed rates and generate a multiplexed output signal representative thereof The output signal is used, for example, by a cab-mounted display or recording device The control system, however, can be reconfigured to both monitor and control the application rates by installing a second control module on the frame The second control module generates rate control signals in response to rate command input signals The rate control signals are applied to the metering device to cause the metering device to meter product to the row units at the commanded rates Commanded rates are set, for example, by a cab-mounted display control module

Modular agricultural implement control system

A control system (100) for agricultural implements (10) (e.g. planters, air drills) is disclosed. The implement (10) has a frame (12) with multiple sections (18, 20), each section having row units (14) to apply product to multiple rows in a field. Implement (10) has global output devices to perform global implement functions in response to global control signals. Each section (18, 20) includes one or more local product metering devices for applying products at varying rates in response to local control signals. Control system (100) includes a global controller (152), and local controllers (154) corresponding to the sections. Global controller (152) receives the global commands and generates the global control signals therefrom. Local controllers (154) receive the local rate commands and generate the local control signals therefrom.
