LWMdraw3:I can't get shorelines,what am i doing wrong?

[Guest]

First,thanks to Ken for this wonderful job.I can see effects ,surf or no surf,but i can't get any differents shore,sand...The width is set to 10 or 20 and the layer to (default) 8. What is wrong?Daniel

Hi DanielIf you copy-n-past the text of your VTPSource.asm file here maybe I or someone will see your problem but I'm uncertain at this point how to give you a hand.ThanksKen

Hi again DanielI counted the number of data point lines three times to make sure of the count and with that found only 57 line/points BUT this says there are 59 line/points:VTPPolyMethod2 31, 1, 0VTPPolyMethod2Ex 2831+28 = 59With that try editing the VTPSource to show:VTPPolyMethod2 31, 1, 0VTPPolyMethod2Ex 26and then try and reassemble and see what happens.Hope this helps yaKen

Hi again KenI've made the change you suggested.I got a window return.I manually added two line/points with the same result.After testing more and more,i realised that when i generate the files at differents Lat/Long,the shoreline stays at the first generation place,and the water is changing.That must explain why i could not see the shore.Perhaps I've not understood your whole help file (sorry for my bad English).Another thing,it seems that 10 or 20 width is not enough,50 is better.Thank you one more time.Daniel

Hi DanielAfter you calculate the FS coordinates the Cell and Area labels, (bottom left of window), displays the bounds for the data points you click on within the image. You should not be having this problem if your working within a single Area, (LOD 13), but if your working within multiple Areas it's important to re-adjust the coordinates and press Calculate again so those label displays show the correct Area your working with. The VTP data points are calculated from those display labels within the program code so if you don't re-adjust the coordinates those data points will not be the correct values. I'm working on the next version and have replaced those labels with textboxes so that the user can simply type the Area bounds they wish without having to re-adjust coordinates along with some other added features.I hope it's working for you ok now.Ken

Ok KenJust another (surely evident)question:To work with correct scale,the 256 X 256 image must represent 1228.8 m X 1228.8 m (one area's size) where i am living (very close to 45 N).Another one:in the text .asm files,no altitude is written;where is it coded?That's all.Thank you again.Daniel

According to the SDK, the Areas avarage 1.2 kms in size but they are determined by decimal degree distance and the cos factor of latitude degrees. And only the LWM determines the altitude.LaterKen
