“How to…Create a Google Earth History Chart For Your Lowrance HDS Units” This topic has been debated a lot and there are a few ways to do this – Rowan Timmer
This topic has been debated a lot and there are a few ways to do this. Most involve a painstaking and timely process to get right. This method will change your life if you have attempted these maps before. After loads of trial and error, trolling the net and private help from an internet friend in the USA, I perfected this method a few years back and have been keeping it a secret until now. The time has come to share it and ultimately get guys onto making these maps quickly and easily themselves. I use this particular method to make maps exclusively for my Lowrance Units.
There are a few things you need to install and change on your PC’s before this will work, but once they are done its really simple. Bear with me.
1 Step 1: Download SAS Planet. https://bitbucket.org/ sas_team/sas.planet.bin/downloads/
2 Step 2: In the SAS planet folder you will need to add two tile storage files. The files you need are: https://bitbucket.org/greverse/greverse.bitbucket.org/ downloads/TileStorage_GC_188.8.131.52.7z https://bitbucket.org/greverse/greverse.bitbucket.org/ downloads/TileStorage_GE_184.108.40.206.7z
Once you have these, copy and paste them into the SAS planet folder that was created when you did the download.
3 Step 3: In the maps subfolder in the main SAS planet folder copy and paste this file : https://bitbucket.org/greverse/greverse.bitbucket.org/ downloads/GeoCacherDirect.zmp
4 Step 4: Locate your Google Earth cache folder. Normally it is here: C:\Users\yourname\AppData\ LocalLow\Google\GoogleEarth\
5 Step 5: Direct SAS planet to the Google Earth cache location
Okay, that’s the hard part done and you only have to do this once on the initial setup.
6 Step 6: Open Google Earth and select the historical date you wish to use. Now you need to make sure that the whole image has loaded, which basically means zooming in as much as you can so that the tiles are downloading to your cache. Basically as you view in Google Earth the tiles you view are being saved automatically to the cache folder you found just now. You just need to scroll around the dam so they activate and download. This allows you to reopen Google Earth and view previously viewed places quickly without having to re download the tiles. Click your way along the dam until you can see it is fully downloaded. When you are done, close Google Earth.
7 Step 7: Open SAS Planet and choose Earth (Google Earth) as the target map.
8 Step 8: Find your dam location on SAS Planet and then select the version date that you used in Google Earth on the time line.
The historical imagery you viewed in Google Earth should now be displaying on SAS Planet.
9 Step 9: Outline the area you want to build with the Polygonal tool and click the green tick.
10 Step 10: Selection manager. Click on the stitch tap and choose KMZ for Garmin Overlays
11 Step 11: Create a target folder on your desktop and save the build to that folder. The file extension is now .KMZ which allows you to open in Google Earth to check.
The picture above shows the historical image auto overlaid and referenced in Google Earth. No more stretching and pulling to fit the image, it is done automatically. Once you are happy with the image (do a small test one otherwise it will be too big for your PC to handle) delete the .KMZ file you built. The step above is purely for test purposes and once you have got the hang of this you don’t need to do it. You will now have to restart the image build step as before but save the file with the file extension from .KMZ to .ZIP. This is important. It must be a .ZIP extension. Click start.
12 Step 12: You will now have a zip-file in your target folder. Download 7ZIP from the net and use that to extract the files. Right click the zip folder and choose 7ZIP/ Extract here. It will save a .KML file and a folder called “files”. Delete the zipped folder you don’t need it anymore.
13 Step 13: Insight Map Creator. Download the free software from the Insight store. You will have to register an account and go through the steps of buying online. There is no fee but you need to do it this way and they will email you the download link. Save the program and open it up.
