PROBLEM TO BE SOLVED: To provide an apparatus capable of estimating the current position based on previously obtained positional information in a mountain climb or the like, even when a radio wave from a satellite can not be received by a GPS system. SOLUTION: The current position estimating apparatus 10 has a map information DB 33 and a barometric pressure/altitude conversion DB 32, and records positional data received from the GPS system and barometric pressure data acquired from a barometer 91 on a measurement log DB 31 in a time-series fashion, such that they correspond to each other. Then, the apparatus estimates the current altitude by referring to the barometric pressure/altitude conversion DB 32, based on the barometric pressure data previously recorded on the measurement log DB 31 and newly acquired barometric pressure data, and then estimates the current position based on the estimated altitude, the positional data previously recorded on the measurement log DB 31 and geography data stored in the map information DB 33.

PROBLEM TO BE SOLVED: To provide a method, a device, and a program for drawing wherein a load on an operator or on a device is small in a process of painting distinguished color. SOLUTION: An input section 10 receives a request from an operator. A storage section 20 stores a control program of a control section 50, a drawing program, and various data including control data, map data, and altitude data. The control section 50 performs integrated control of each section of the drawing device, judges whether the altitude of each area divided by a reference line in a map to be processed is higher or lower than the reference line on the basis of the altitude of the reference line specified by the operator through the input section 10 and the altitude data stored in the storage section 20, and displays a map with different colors painted according to the result of the judgement on a display section 30.

Method, device, and program for drawing

PROBLEM TO BE SOLVED: To provide a map information creation device with reduced information quantity required for creation of a map on which land areas and water areas are distinguished. SOLUTION: This device is provided with a boundary data storage part 11 which stores the boundary data for specifying the boundaries between the land and water areas, a specific data storage part 12 which stores the specific data specifying whether a certain location should be in the land or water area, an extraction means 13 which extracts the boundary data of the boundary contained in a range desired to be created on the map and the specific data of a location contained in the range when specifying the range together with a request to create the map, a drawing means 14 which draws boundary lines between the land and water areas in the range based on the extracted boundary data, a determination means 15 which determines whether a closed region generated by the boundary lines should be the land or water area using the extracted specific data, and a generation means 16 which assigns a first color to the closed region determined to be a land and assigns a second color to the closed region determined to be sea based on the determination result and creates the map.

Map creation device

PROBLEM TO BE SOLVED: To solve the problems in which information indicating positional information of a flying object cannot be transmitted to a terminal device which controls the flying object, and a map corresponding to the position of the flying object cannot be output in the terminal device which controls the flying object.SOLUTION: A terminal device comprises: a map information storing unit for storing map information having one or more pieces of map positional information indicating a position on a map, and indicating a map; a receiving unit for receiving flying object positional information indicating a three-dimensional position of the flying object from the flying object; a sky-map information acquisition unit for acquiring sky-map information indicating a sky map as a map using the position of the flying object indicated by the flying object positional information as a view point, by using the map information and the flying object positional information; and an output unit for outputting the sky-map information acquired by the sky-map information acquisition unit. The terminal device can transmit the positional information indicating the position of the flying object to a terminal device which controls the flying object. Further, the terminal device which controls the flying object can output a map corresponding to the position of the flying object.

Terminal device, method for outputting sky-map information, and program

PURPOSE:To display not only the warning area at an altitude higher than that of one's own plane but also a downward monitoring area to which a clearance is set together. CONSTITUTION:This map display device displays a map on a display device 11 by reading three-dimentional map data of an area corresponding to one's own position from a map data memory 1, compares one's own altitude H1 and altitude data Hx read from the map data memory 1 and displays the area higher than one's own altitude H1 as the warning area to the display of the display device 11. The map display device is provided with a clearance input means 6 for setting/inputting clearance (h), a subtracter 7 determining a downward monitoring altitude H2 by subtracting clearance (h) from one's own altitude H1, a comparing circuit 10 comparing one's own altitude H1 and the downward monitoring altitude H2 with altitude data Hx and a color control circuit 9 which displays in different color an area as the downward monitoring area to the display device 11 when altitude data Hx is between H1 and H2 as the result of the comparing by the comparing circuit 10.
