Terrain Builder Map Size with Sat

[Sandro Saitek 0]

Moin dear community,

maybe you can help me. I have a terrain made ​​with a size of (5120 x 5120) x 10 = 51200
Now I have the texture of the Map ( satellite ) made ​​in 4 different parts. Each with 12800 x 12800 resolution (it´s a .bmp data). Now when I load the parts into the Terrain Builder and coordinate adaptive, it fits with the Highfield together not quite.

 

How do I adjust the positions of a right?

With a jpg, png file I do not want to do that and I did it try with a resolution of 5120 x 5120. But if you zoom in, it's pixelated.

 

Here are some screens :

Thanks for the help ♥ so that you save my day

A cell size of 50 is going to look rubbish. Use 10 or lower, I think most people use 4 - 6

 

Here is a chart to show you sizes etc

EDIT:

 

Your terrain is 51200x51200.

 

Your satellite tiles are 12800, and you want them in a 2x2 Grid.

 

12800x2 = 25600, which is half the size of your Terrain.

 

The only way for them to cover all of your Terrain and in the correct place would either be to use a larger (25600x4) image set, or let TB stretch them to double thier original size.

 

 

 

Regarding tiling rasters - I wrote this before I realised your source imagery would not directly fit your mapframe, but the same process still applies, albeit with a different set of numbers)

 

 

You will have to offset your rasters' coordinates in the Rasters Tab in the Layer Manager, (You can also set these offsets when you import the data).

 

Since your using 2x2 grid of images at 12800px each you have to offset the rasters' coordinates - same goes for your surface mask raster's if it is also split into 2x2 images the same way.

 

Here's a rough guide for the offsets you'll need, given 12800px imagery:

 

E = easting | N = Northing

Left Bottom : E = 200000 N = 000000 

Right Bottom : E = 212801 N = 000000

Left Top : E = 200000 N = 012801

Right Top : E = 212801 N = 212801

The Left Bottom image(12800x12800px) occupies  the pixel coordinates from(inclusive) 200000 E, 000000N all the way up to 212800 E, 012800 N.

 

To set the next raster (Right Bottom) up in the correct position you start it one pixel coordinate AFTER the final coordinates ^^^ of the first image in the grid.

 

This means your Right Bottom raster goes into coordinates 212801 E, 000000 N. 

 

Which is 1 grid coordinate more than where the previous rasters pixel coordinates ends.

 

The same method is used for adding the top row of rasters, which should be clear from the example above in the <code> section.

 

 

This same process applies regardless of raster size, you just need to do the math for your raster size to get the coordinates you require.

Thank you, very much <3
