Utilizing mapping tools

[GoneFishingLTN]

Hey so I have google earth open on the computer and navoics open on the lake I’m trying to research. I’m just having trouble really navigating through these two things are there any tips?

the lake I’m looking at is twelve mile lake in Iowa
example on google earth I see a lot of white dots.....is this rock?
cant you adjust the year your looking at on google earth

If you are using google earth and are looking at the 7/2016 image, I would tend to believe the white dots are not rocks, turning the date back to 9/2012 the water was significantly lower and those white dots are not present in the same locations.  Rocks tend to not move.  It may be buoys or maybe even birds on the pond surface.

The white dots on the 9/2012 image might be rocks (it would be a really widespread field or them) or possibly and more likely in my opinion, windblown whitecaps 

 

Older satellite images can be found by checking the Historical Images box under the View tab and then sliding the bar on the timeline.

Yes there are plenty of rock piles in that lake (close to the bank).

 

Yes you look at historical images on google earth. It is a clock looking button with a green arrow to bring up the timeline and then you can scroll left and right to change the date.

 

PM me for more specific details about that lake.

When your using your Navionics App. with the lake your doing research on go to select menu and then make sure you have community edits on.  Specifically if you are trying to identify rocks or other fishing structure it is likely that someone has marked these type of things on your App.  under the menu section you can select Satellite overlay with several different options such as chart density for your contour lines and even Depth shading which makes it real easy to identify target depths at a glance.  There are many other features on the App. that are very helpful for studying a body of water.  One important thing to do is always click on update charts in the menu as well so that you are getting the latest data possible.  Please feel free to send me a message if I can help you with any questions you may have with the App.  I use it all the time planning on all the bodies of water I fish.  My wife gets a little ticked sometimes because I'm usually studying a map rather than watching the movie LOl...
