Description

海図表示装置及び海図表示システムNautical chart display device and nautical chart display system
　本発明は、海図情報及び陸上地形情報を取得して海図を表示する海図表示装置及び海図表示システムに関する。 The present invention relates to a chart display device and a chart display system that acquire chart information and landform topography information and display the chart.
　近年、地形情報を取得して地図を表示する地図表示装置は、船舶の航海時に使用される海図や、そのときに航海を行っている船舶の位置や進行方向等を表示する海図表示装置に限らず、自動車に搭載されて目的地への道案内を行うナビゲーションシステムにおいても広く利用されている。また、携帯電話やスマートフォン、パーソナルコンピュータにおいても、同様の機能を備えたものが広く利用されている。 In recent years, map display devices that acquire terrain information and display maps are limited to charts that are used when navigating ships, and chart displays that display the position and direction of travel of ships that are navigating at that time. Moreover, it is also widely used in navigation systems that are installed in automobiles and provide route guidance to destinations. In addition, mobile phones, smartphones, and personal computers that have similar functions are widely used.
　従来の紙に印刷された地図では、例えば目的地を示す目印等をペン等で書き込むことが可能であるが、そのような書き込みが多くなると、地図が読みにくくなる場合がある。また、例えば海図では、同様の理由により、通常、海図に直接ペン等で書き込みを行わないようにしている。しかしながら、地図に書き込みができないと、地図と各種情報を記載したメモのようなものと両方参照する必要があり、煩わしいものである。 In a conventional map printed on paper, for example, a mark indicating the destination can be written with a pen or the like. However, if such writing increases, the map may become difficult to read. Further, for example, in a chart, for the same reason, normally, writing is not directly performed on the chart with a pen or the like. However, if it is impossible to write on the map, it is necessary to refer to both the map and a memo describing various information, which is troublesome.
　そのため、上記のような地図表示装置では、例えばタッチパネルを備えた装置において、タッチパネルから手書き情報を入力することが可能な地図画像表示システムが知られている（例えば、特許文献１及び２参照。）。この地図画像表示システムでは、必要に応じて表示範囲の拡大や縮小を行うことが可能であり、また、タッチパネルから手書き情報を入力することが可能になっている。さらに、その入力された手書き情報は、地図の表示範囲の拡大や縮小に応じて大きさも変更可能になっている。 Therefore, in the map display apparatus as described above, for example, a map image display system capable of inputting handwritten information from the touch panel in an apparatus having a touch panel is known (see, for example, Patent Documents 1 and 2). . In this map image display system, the display range can be enlarged or reduced as necessary, and handwritten information can be input from the touch panel. Furthermore, the size of the input handwritten information can be changed according to the expansion or reduction of the map display range.

　ところで、このような地図画像表示システムは、地図画像を操作する場合と、手書き情報を入力する場合とで切り替える必要があり、特に大人数で同時に地図情報を見るような場合、簡便に切り替えることが可能な手段が望ましい。また、このような手書き情報は、地図情報に表示されている建物等に紐づいていると、そのような建物等がなくなった場合にどのように管理すべきかが問題であり、例えば、大規模な災害があった場合に手書き情報が表示されなくなる、海図の場合には、地図に紐づける情報がない、という問題があった。さらに、このような手書き情報を共有化して他の端末等でも参照できることが望まれていた。 By the way, such a map image display system needs to be switched between a case where a map image is operated and a case where handwritten information is input.
