安卓简易,高清海图应用程序评测

对于你的安卓设备不是最佳的选择
翻译者-------帆译组:张益博

应用程序,联想A1,智能机,接收器,做什么 安卓简易、高清海图应用程序评测 MarinteLiteApp.jpg


  安卓简易海图是一款免费的应用程序,类似于海图标绘仪如果你的安卓智能机或者平板上有一个内部或外部GPS接收器,它可在海图上显示你的船位,它使用的是标准NOAA格栅图,类似于许多其他显示标准纸质海图的应用程序。

   该应用免费使用,是一个诱惑,通过免费下载的海图部分(即简易版)用起来很差,如果你想要使用该应用哪怕是再多一点地理显示,你就得升级应用至高清版本,得花9.99$,来避免免费版中卡,慢的毛病(以及可移去横幅广告)。

    因此,它实际上不免费,当然除了一些在很小的固定的活动区域的船来说下载下来供离线使用,或者是其他一些能确保自己时刻联网不断状态(这很难达到)的船用起来能便利一些。

除此之外,nuti海图甚至还缺乏一些许多其他低成本海图应用都有的特点。
版本评估:简易海图(免费)  高清海图(9.99$)
版本2.7(22) 2.3运行于联想A1平板


它能做什么
这是它的一些主要特性:

  • 启动,联网后你看到你所在位置的基本海图。你可以缩放海图来选择一些区域(简易),花一点时间,下载下来供脱机使用
  • 一旦你获得了适当的简易海图,在NOAA海图上查看你的船位,通过缩放查看前面以及四周
  • 再次返回在线下载附加简易海图
  • 在图上选择自己船的轨迹并且可保存
  • 通过图的下角选择自己标记航点
  • “航点指引”功能(但不是完全指引功能)
  • 可选择测量两点间距离
  • 在线(不是离线)辅助界面


不足
简易,高清海图不像一些其他的应用,一个完全的海图测绘仪,只简单基本的显示你的船位,允许航点以及其他一些功能的简单使用。它不包括典型的导航功能(没有多航点功能,不显示速度,航向等)对于一款免费的应用程序这样的简单功能可能就够了,其简易版除了是免费下载以外,要想很好的用它你会非常沮丧于它的局限性,你必然会升级至付费高清版(9.99$显然是开发商的意图)为了下载较大部分的海图。即使这样,下载还会很慢,繁琐,并且可能会导致在不同的缩放级别和分辨率之间出现混乱拼接。

这都是可接受的,那么,来比较下高清海图和其他有着丰富功能的付费应用,像Memory-Map,MX Mariner还有NavionicsMarine&Lakes结果还没开始比较呢,用户就已经抱怨其运行的慢了。

总结
其有限的功能,导致我都有可能推荐几乎任何一个其他有关海图的应用程序了,对比看来像这软件是十年前做的。还有更糟糕的是它的图表功能。即使是付费版本,下载图表也是非常繁琐的,而且很容易出错,到最终也不知道你得到了什么。例如,你选择了一个小范围的图表来下载(在线)。然后,离线(正如许多现实情况一样),你开始放大刚下的海图区域来查看你的船位,突然意识到你忽视了细节,因为缩放分辨率不够图像变得模糊(在你第一次下载海图时,你必须记住,要选择最佳的缩放级别)。你不得不回去,联网,再次下载该区域具有更高分辨率的图。在一个更大的区域这样重复n多次,你可以结束这个让人发狂的缝图部分,这样图就可以放大到不同层次了。如果你更注重细节,在简易图上精益求精的话,最好别这样,当你放大时,在它旁边的地方将很容易变得模糊甚至图中还会产生一个洞。

在一个复杂的航行区航行,绝不是我相信我的船或者相信我的命这样简单,这不是儿戏!如果你喜欢栅格图(NOAA图表,看看与纸质图相似),建议你花几块钱买下MX Mariner或者Memory-Map,这都是功能很全的应用程序,里面下载了全部的NOAA海图,并且永久可用,可放大或无缝地转移至较小的或较大规模的图表。或者如果你喜欢矢量图,建议了解下Navionics Marine & Lakes。

注:当我从我的安卓平板卸载该海图时,发现数据和图表的文件仍然存在,为了释放平板宝贵的空间。我不得不又通过电脑手动删除了这些文字性的上百个文件夹,以重新获得约130MB的存储空间(幸好我当时没有通过这个APP下载所有的大面积区域)。

Review of Marine Charts Lite and Marine Charts HD Android Boat ChartingApp
Not the Best Choice for Your Android Device
Marine Charts Lite is a free Android app that like a chartplotter showsyou your boat's position on a chart, assuming your Android smartphone or tablethas an internal or external GPS receiver. It uses standard NOAA raster charts, the same asmany other apps - which display the same as standard paper charts.
Theenticement here is that while the app is free, the method by which you downloadchart sections (which the app calls "tiles") for use is so clunkythat if you want to use this app in more than just a tiny geographical area,you're motivated to upgrade to the Marine Charts HD version, sold for $9.99, toavoid the slowness and problems of the free downloads (and to remove the bannerads).
So it'snot actually free except for those who boat in only a small geographical areathat can be more easily downloaded for offline use on the boat - or for peoplewho are constantly connected (a risky thing to trust on a boat).
In addition, NutiCharts lacks many of the features of otherlow-cost charting apps.
Versionreviewed: Marine Charts Lite (free) and Marine Charts HD ($9.99) version2.7(22)
Tested on Lenovo A1 Tablet running Android 2.3

What It Does
Here arethe key features of Marine Charts Lite:
·        On startup, when online, you see a base map chart of yourlocation. You can then pan around and zoom in somewhat to select small chartareas (tiles), a little at a time, to download for offline use.
·        Once you have appropriate chart tiles, view your boat's GPSposition on the NOAA chart - zoom and pan to look ahead and around.
·        Return online later to download additional chart tiles.
·        Option to track your boat on the chart and save the track.
·        Option to mark waypoints by dropping pins on the chart.
·        "Guide to waypoint" function (but not full routingfunctions).
·        Option to measure distances between two points.
·        Online (but not offline) help screens.

The Downside
MarineCharts Lite and Marine Charts HD are not a full chartplotter like many otherapps, but essentially just show your position on the chart and allow simple useof waypoints and other functions. It does not include typical functions forroutes and navigation (no multi-waypoint routes, no speed and course, etc.).Its simple functions might be fine for a free app, except that its freedownloading of chart tiles is so frustratingly limited that to use it well youinevitably want to upgrade to the paid HD version ($9.99 - obviously thedeveloper's intent) in order to download larger sections of charts. Even then,downloading is slow and tedious and may result in a chaotic stitching of chartsections at different zoom levels and resolutions.
It's appropriate, then, to compare Marine Charts HD to otherpaid apps with many more features, like Memory-Map, MX Mariner, and Navionics Marine & Lakes - and then it really doesn't evenbegin to compare.
Usersalso complain that it runs very slow.

Conclusions
Itslimited features alone would cause me to recommend virtually any other chartingapp over Marine Charts, which in contrast looks like software written a decadeago. But worse still is its chart functioning. Even with the paid version, itis very tedious to download chart tiles, and it's easy to make a mistake andend up not really sure what you're getting. For example, you select a certainarea of a small-scale chart to download (when online). Later, offline (as inmany real-life boating situations), you start to zoom in to see your boat inthat chart area and suddenly realize you don't have enough detail because thezoom doesn't go far enough in or becomes blurry (you have to remember to selectthe best zoom level when you first download the chart section) . You have to goback online and download some more in the same area with a higher level ofzoom. Do this several times in a larger area and you can end up with a crazyquilting of chart sections that can be zoomed to different levels. If you havemore detailed chart tiles in one place compared to the place just beside it,when you zoom in that other place will simply become blurry or a hole in thechart.
This is not something I'd trust my boat or my life to in atricky navigational area! If you like raster charts (the NOAA charts that lookidentical to paper charts), then spend a few bucks more and get MX Mariner or Memory-Map, whichare full-featured apps that download entireNOAA charts and keeps them all in focus whenzoomed and seamlessly shifts into smaller- and larger-scale charts. Or if youlike vector charts, check out Navionics Marine & Lakes.

Note: When I uninstalledMarine Charts on my Android tablet, the data and chart files remained, using upprecious resources. I had to manually delete that folder with literallyhundreds of files via my computer to regain some 130 MB in storage room (and Ihad not downloaded all that large an area with the app).
