I normally take the position of the end user who does not RTFM

again thanks for the hard work

Chill out

Tore,

I found the problem. I will have a new version shortly that fixes it.

[phiggins]

r.fairman, Well if you are overlaying an image that has depth soundings on it, I can't determine what they are, you have to tell me by entering it.

[phiggins]

Well I fixed Tore's problem. I had some temporary files hard coded as the C:. His temporary drive is D:

I've uploaded the new beta version V3.3.5

[phiggins]

I put in some checks for testing if the waypoints in a GPX file were put in correctly in V3.3.5 and the checks were wrong. V3.3.6 corrects it which is now uploaded.

Hmmm the problem I keep running into is resolution. I can't seem to find a way to make anything that doesn't turn into an unintelligible mess. I'm not sure if it has to do with my location and the absence of of harbor charts. I am in Penobscot Bay Maine and all of the charts are huge. When I go to overlay in GE either the GE image gets stretched or the Chart gets pixelated to death. I challenge anyone to come up with something for this area. I am primarily working with NOAA charts 13309 and 13302.

[phiggins]

How about this. Done with the Beta GE2KAP.V3.3.6

[unbusted67]

That is very nice. How did you do it with an ENC? I have been trying to use RNC's this whole time. Every time I try to line up an ENC in the Image overlay mode in GE I can't seem to get the corners to line up. The lat and lon formatting is different.

Also how do you adjust the amount and style of depth info in open CPN, I always seem to end up with too much info, the old high water/low water reading is just too cluttered

[phiggins]

Yes with an ENC and make a image with coordinates.

Paul..

Your #247 .kap overlay looks great,much improved..

Tore

[phiggins]

Thanks Tore

Unbusted67, Not sure what you mean by the highwater/lowwater. This is another chart I created as shown on OpenCPN from GE2KAP.V3.3.6. Here is the whole procedure that I did to make it:

1. On OpenCPN open the route manager and delete all waypoints and routes and tracks. Close the route manager.

2. Drop a waypoint in the upper right corner of the chart ( I used ENC US5ME26M) and the lower right.

3. Reopen route manager and Export All wayoints to Belfast Harbor.gpx

4. Do a print screen.

5. Open a image program I used Paint and paste the image into it.

6. Crop the image to the waypoints.

7. Save the image as Belfast Harbor.jpg

8. Start Google Earth and center it on Belfast Harbor.

9. Start GE2KAP.V3.3.6 and select BelFast Harbor.jpg in the overlay field.

10. Enter a name for the chart: Belfast Harbor

11. Press Create KAP. GE2KAP will do the rest.

Notice how the land areas show what GE was showing.

Just experimenting to see if I can make the result clearer and found if I save the cropped image in Paint as a 256 color bitmap, I get the result below..

[phiggins]

I decided to try just overlaying the BSB/KAP chart 13309_1.kap. The advantage being you don't have to go through all stuff building the image from the ENC chart, you just specify the kap chart as the overlay. Below is the result with the fuzz at 8%. The problem with it is that the chart has streets embossed on it so they are showing rather than the streets from GE. But its not too bad, eh?

Thanks for the step by step Paul. Very helpful. By High/low water I mean the dual soundings you get on an ENC. They give you two soundings and put them right next to each other making it very hard to read.

As per your most recent post that is very impressive. Can you give me the step by step of how you did that? As I said before when I use an RNC everything becomes badly pixelated, either on the original KAP or on the GE image.

[phiggins]

That was real easy, I just started GE2KAP.V3.3.6 and entered the chart in the overlay image/chart field and pressed Create Kap. I had to Redo it a few times to adjust the fuzz.
