Crops issues with season mods

Recommended Posts


I created a 10x map using 4097 dem with pixel at 2.5. 
all the gdm files are at 8192. 
I completed the map and started the test. I discovered an issue when I use season 

kind of crosses appear on my fields characterized by higher crop maturity. I enclosed captures to explain this phenomenon. Need your help I don’t know if it s a Pb of file size, script or other. 
thank you in advance

Looks like you have got a problem with your Gdm files being the wrong size, what have you based your calculations on dem/gdm size as normally the following applies

Normal map of 2k x 2k  dem- 1024 with 2 pixel definition

 gdm -- 4096 x4096

tipCol 4096 x 4096

seasons mask 4096 x 4096


an 8192 x 8192 gdm size normally equates to a 4k x 4k map with 2 pixel resoloution

Hi what does it mean - with 2.5 pixel and dem 4096 my gdm should be 10240x10240?

As far as I'm aware you can only change the dem map size by adjusting the pixel density in steps of 1

ie 1024 x1024 pixel density 2 = 2k x 2k, pixel density 3 = 3k x 3k  etc

The gdm/grle files however have to work to the power of two so when divided by the pixel density the result is a whole number to avoid distortion

i.e gdm 4096 pixel density 2 = 2048

gdm 4096 pixel density 3 = 1365.3333

gdm 4096 pixel density 4 = 1024

in your case ----gdm 8192 pixel density 2.5 =3276.8

Hence the reason map sizes are normally 2k x2k, 4k x4k, 16k x 16k with 2pixel density
