This removes any problems of the 2GB cache memory for offline work and cruisers will quite often share images that they have converted. This software takes a satellite picture of your choosing and converts it into a KAP file that’s readable on the chartplotter. One great use of the software is that you can overlay satellite pictures onto the plotter on your laptop by using GE2KAP software (what I used), which has in turn been superseded by Sat2Chart. There are many free charts you can download onto this software, as well as ones to purchase. Many cruisers use Open Source CPN, which is chartplotting software on a laptop. With the MotionX app you can switch between satellite images to find the clearest There’s also a 2GB restriction in the cache memory for use offline. That’s great when using broadband, but on a poor connection can be slow and time-consuming. Fortunately a history slide bar allows you to go back through previous pictures of the area to find the clearest view. However, some Google Earth images are affected by cloud cover, or the sun was at the wrong angle when the image was taken. We can add a GPS so that our position is seen on the image. With Google Earth, zooming in on an area where there is coral we can quite clearly see just where there are shallows and deeper areas. Using satellite imagery takes the concept of eyeball navigation a stage further. It takes a lot of practice to estimate actual depth but it is relatively easy to separate shallow from deep water. On a cloudy day it is most difficult to determine depths. Polarising sunglasses are useful, but the sun must be behind you otherwise glinting from the sun makes the depth unfathomable. Hoisting someone aloft to look down from the spreaders can aid navigation. When sailing among coral the first tactic is to use eyeball navigation: with clear water and the sun behind it is quite clear where shallows are and what needs to be avoided. I don't know how the Google satellites work, so it might not even be possible to add a day/night setting with our current technology.We have got used to chartplotters and GPS being very accurate sometimes (I think) too accurate as we pass ever closer to obstructions, confident we’ll be safe because it shows them on a computer screen.īut when cruising further afield we need to understand that the charts may not be as accurate as we’d like them to be, and we need to sail more conservatively than we might, for example, in north-west Europe. For example, you could set it to midnight setting, and everything would be dark and windows would be glowing. One thing that would be cool is adding a function where you could change the time of day. Overall, it's amazing, and I fully recommend it to any geography or history nerd. For two, places like China, Russia, and North Korea obviously aren't 3d because those countries dont give us permission to analyze there country at every angle thousands of times (for good reason). For one, most of the non-3d areas are random countryside's or small towns, which makes sense, as it would take so much effort to turn a tiny little town in the middle of Canada to 3d, and it's not worth it. Unfortunately, the whole world isn't 3d, but that makes sense for multiple reasons. This is a great app and I'd recommend getting it. And yes, even though I didn’t pay anything I still feel shortchanged. I now know that if I had a desktop I’d be able to look at the moon and mars so I feel really gypped now. Overall really great concept but what I’m gathering from other reviews, the app particularly for iPad is super low quality compared to others. It is absolutely impossible to tell one country/state from the next with the impossibly thin tan line separating everything that, oh yea, is the same color that is used for most of the landscape. Also, it would be really enjoyable (and easier on my old lady eyes) to be able to make borders bold or different colors or even cut out a region to view it individually. You can’t adjust any type of visual settings so if you zoom too far in on, say, China, you get a million different location names in English and Chinese and you can’t even see the land under all the text. I am terrible at geography and thought this would help me with a class I’m taking but I was mistaken. It’s like they took what they were in the process of developing years ago and just threw it up without even looking at it for a quick review. It takes a lot of disappointment for me to write reviews but this app is just so flat. Not Even Basic App Comforts (2020 iPad Pro)
