     DETAILED DESCRIPTION 
       [0056]    The foregoing and other objects, features and advantages of the embodiments of inventive concepts will be apparent from the more particular description of embodiments of inventive concepts, as illustrated in the accompanying drawings in which like reference characters refer to the same parts throughout the different views. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the inventive concept in the drawings. 
         [0057]    The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting of the inventive concepts. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises,” “comprising,” “includes” and/or “including,” when used herein, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
         [0058]    It will be understood that, although the terms first, second, third etc. may be used herein to describe various limitations, elements, components, regions, layers and/or sections, these limitations, elements, components, regions, layers and/or sections should not be limited by these teems. These terms are only used to distinguish one limitation, element, component, region, layer or section from another limitation, element, component, region, layer or section. Thus, a first limitation, element, component, region, layer or section discussed below could be termed a second limitation, element, component, region, layer or section without departing from the teachings of the present application. 
         [0059]    It will be further understood that when an element is referred to as being “on” or “connected” or “coupled” to another element, it can be directly on or above, or connected or coupled to, the other element or intervening elements can be present. In contrast, when an element is referred to as being “directly on” or “directly connected” or “directly coupled” to another element, there are no intervening elements present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). When an element is referred to herein as being “over” another element, it can be over or under the other element, and either directly coupled to the other element, or intervening elements may be present, or the elements may be spaced apart by a void or gap. 
         [0060]      FIG. 1  is a high level block diagram of a system for obtaining publications linked to geographic locations in accordance with an embodiment of present inventive concepts. In an embodiment, the system includes a mobile device  10  operated by a user  20  installed with an application (also referred to as an “App”) that is programmed with a graphical user interface (GUI) to display a geographic area (e.g., a graphically rendered map or chart) as identified in a process step  50 . In various embodiments, the mobile device  10  can be a “smart” phone, tablet, laptop, electronic plotter, or other mobile devices. 
         [0061]    The App of the mobile device  10  is programmed to find and list published articles linked to a particular geographic area (as referred to in a process step  90 ). In an embodiment, the particular geographic area is an area proximate to the physical location of the mobile device  10  (e.g., within a certain radius of the physical location) or, for example, an area selected manually by the User  20 . Determining the physical location of the mobile device, such as referred to in a process step  80 , can be accomplished via a GPS (e.g., from GPS satellites  30 ) or through other methods including, for example, cellular signal positioning techniques that are known to those of ordinary skill in the art. From the list of published articles, the user can select an article to download and display, as referred to in a process step  100 . In an embodiment, permission (e.g., a license) to download and display the publication can be purchased through the GUI programmed into the App or, in an embodiment, be purchased through a separate application (e.g., a web browser) to which the App can direct the User. In an embodiment, after downloading, the publication is displayed within and can be viewed from the App GUI (referred to in a process step  120 ). In an embodiment, the publication can be displayed in a separate application (e.g., a web browser or electronic reader). In an embodiment, the publication is downloaded to the mobile device (e.g., compter-readable memory) or an attached data storage device and made available on the device for later viewing without further downloading necessary. In an embodiment, the publication is stored on an external server from where the mobile device can access and display the publication. 
         [0062]    In an embodiment, purchasing and downloading publications for display is managed via a server (e.g., of Servers  40 ) which, together with the mobile device  10 , can be connected to and communicate via the Internet  60 . In an embodiment, one or more Servers  40  are programmed to provide user accounts for particular users, who can log into and, through these accounts, purchase the ability to download and display the publications. In an embodiment, the listings of publications available for download are stored by and accessed through the server and, in a further embodiment, the publications themselves are stored by the server. In an embodiment, permissions to download publications and/or the publications themselves can be acquired directly through a publisher  25  or authorized distributors (e.g., Amazon Kindle, iTunes, etc.). In an embodiment, once purchased, viewing of a publication can be made accessible on more than one device such as, for example, different mobile devices and/or a desktop computer. In an embodiment, the App can operate on a non-mobile device such as a desktop computer. 
         [0063]    In an embodiment, the publication is an article such as from a magazine or website, an article from a newspaper or news site, or a book. In an embodiment, the publications are related to boating accessories, boat maintenance, boat testing, cooking, cruising, diving, fishing, kayaking, lifestyle, power boating, and/or sailing. In an embodiment, the publications are related to any recreational activities or tourist activities and destinations including, for example, restaurants, inns, and other accommodations. 
         [0064]    In various embodiments, the publications are linked or related to a geographical area by a reference to the geographical area within the publication, by a type of activity (e.g., sailing, fishing) that occurs in the geographic area, and/or by a predetermined or pre-established geographical relationship to the publication that is, for example, tracked/compiled by a server or other source. 
         [0065]      FIG. 2  is a process flow diagram of a system for obtaining publications linked to geographic locations according to an embodiment of present inventive concepts. In an embodiment, an exemplary process flow of an exemplary App includes the step  200  of the App displaying a GUI having a representation of a geographic area and attempting to establish a link between the App and a server (e.g., one of Servers  40  of  FIG. 1 ). In a proceeding step  210 , the App can query the host mobile device for the physical location of the device. If the App/Device can obtain a present location, the App can transmit the coordinates to the server, which will be used in connection with the established link to the server. Otherwise, the App can select default coordinates (e.g., last known location, last entered location) or query the user for a location, and send those coordinates to the server. In response, the server can transmit a list of publications geographically linked to the location of the device, for example, articles pertaining to geographic locations within a specific radius from the device or designated location or within an otherwise selected geographic region. 
         [0066]    In an embodiment, as in a process step  260 , the App then provides an option for the user to download and display a publication from the list of publications, some of which may be designated as available only with purchase. If the user selects a publication for download/display and the publication is designated as available only through purchase, and the publication has not already been determined by the App/server as being purchased by the user, the user will be prompted for payment and/or deduction from a credit balance established for the user in an account. In an embodiment, payment may be made with, for example, a credit or debit card, or similarly available payment services. In an embodiment, if the user has already been established by the App/server as having purchased the publication or the publication is otherwise freely downloadable, the user will not be prompted for payment. 
         [0067]    In an embodiment, after permission for download/display has been established, the App will provide an option for the user to download the publication if not already downloaded on the device, and will proceed to download the publication from the server or other source as applicable (e.g., as referred to in steps  280 ,  290  and  295 ). In an embodiment, the App or a separate application may then display or otherwise facilitate display of the publication. 
         [0068]      FIGS. 3A-3B  are screen shots of an application interface for listing and selecting published articles linked to a geographic area according to embodiments of present inventive concepts.  FIG. 3A  is a screen shot  300  of a GUI showing a nautical chart including a geographic area represented by an arrow designator  305 .
