How do I get large areas of Google Earth images into KAP format?

I will be heading off to the Solomon Islands and I understand the charts are not too acurate there, nor is the mobile coverage much good. I am wanting to download a large number of Google Earth images and store these for offline usage.

I can do the download with SAS.Planet and save this in GeoTiff format but none of the navigation software will recognise any of the formats that SAS.Planet produces.

I can convert these to KAP but only if they are very small. If i try to convert a large Tiff file with Ge2Kap, imgkap or any other program I try ( windows or Linux) they all crash.



I want to be able to capture whole islands or whole reefs and not have to do the whole thing in 0.5nm x 0.5nm blocks.



Is there a way?

Re: How do I get large areas of Google Earth images into KAP format?

I can understand your plight. I have spent hours on Google Earth with GE2KAP downloading satellite pics for OpenCPN for Fiji and New Caledonia....I don't know of any other way to do it.

Re: How do I get large areas of Google Earth images into KAP format?

If you are happy paying a small subscription to VentureFarther, or contributing data, the VFKaps plugin makes this possible. You have the option of using Bing and Nokia satellite images as well as Google.


Note: These are Google Map images, not Google Earth, so there are no historical images.

There is an easy way using GE2KAP and SAS Planet. I've done thousands of charts in SE Asia.



Here is my briefing/tutorial that may help you. Download


And some info on SAS Planet Download

Re: How do I get large areas of Google Earth images into KAP format?

I find Ovitalmap is the easiest, download on to tablet, mac or android. I used says planet for along time but now prefer ovitalmap for ease.

I recommend you revisit the settings required in SAS Planet. In GE2KAP press F1 for the Help and navigate to 'SAS Planet Setup'.


If that doesn't work please PM me.

Re: How do I get large areas of Google Earth images into KAP format?

This thread brings back memories of my cruising in the Solomon Islands in 1990 and 91.



I made three satellite imagery charts of the north shore of Guadalcanal. You can download them here.


These charts were created using imagery from ESRI/ArcGIS available via SAS Planet. The imagery from Google Earth was not acceptable at the zoom level I chose along the coast.


And for comparison the Venture Further generated Google Earth charts is also shown below.



BTW, the cm93 charts appear to be in good correlation with the satellite imagery.

Quitta,

Please reproduce the problem on GE2KAP with the Diagnostic level in the optios set to 1 then send me the GE2KAP.log file and any input files that you used. My email is in the Help (f1)

Re: How do I get large areas of Google Earth images into KAP format?

You can download large area hi resolution KAP Google Earth charts with
Terra Incognita
https://sourceforge.net/projects/terraincognita2/
This program does not allow "Historical Imagery" so I use GE2KAP with a large resolution Monitor to fill in Clouded areas etc
I have attached a help file

Steelcat,
That is exactly what I needed, put a pollygon around an island and create a .kap chart that will work with OpenCpn.

And that is exactly what GE2KAP can do. Do you need some pointers about doing that?

In just a few minutes I made this chart of Savo Island with a polygon around it.


Is this what you are looking for?
