My script to import Moon and Mars Datagrid (altimetric data)
http://sites.google.com/site/moonmaplab/port-mehdia
The name is MoonAndMars.

You can found here the dataset :
MOON: http://imbrium.mit.edu/DATA/LOLA_GDR/
The file are:
LDEM_4.IMG: 4 px/deg
LDEM_16.IMG: 16 px/deg
LDEM_32.IMG: 32 px/deg
LDEM_64.IMG: 64 px/deg

MARS: http://pds-geosciences.wustl.edu/missions/mgs/megdr.html
From 4 to 128 px/deg

You must download the IMG file and the LBL file in the same directory
Select the image file, choose the coordinate, check the numbers of vertex :eyebrowlift: and then click on Exec.

Thanks for the update to this great script!

3

it looks awsome

and is it for 2.5 if not is it gooing to be ported to 2.5 soon?

Thanks for the update

happy 2.5

i saved the LBL as HTLM is this ok ?

Don’t change the extension of the file, You must have 2 file in the same directory with the same name and with extension IMG and LBL,

Then run the script, (you can open the file with notepade and then copy and paste the code)

Click Select and search you directory with the file. Select the coodinate that you want import and press Exec. That it’s all :wink:

Now I must be going, but more late I explain better all the thing

resolution of maps

i think the LDM4 represent something like 30 KM / Pixel
i mean this is ra eally rough approximation of the surface
but the file size is very small

what are the other resolution values if you know theses?

Thanks

Thanks

RickyBlender: but still get an error for

I think that you have a wrong version of the script. The correct is named MoonAndMars.py

In any case here you can foun the blender file. http://www.pasteall.org/blend/2859

For the moon file LDEM_4 is 4 pixel(or point) for degree
LDEM_16 is 16 pixel for degree and so on
To calculate the precision on the equator (more you are near the pole, more is the precision) you must use this formula:
Radius of the moon2Pi/360/px/deg.
So for LDEM_64 the precision is 470 meter. (ther are more of 265 million of points)

For Mars is the same but you must change the radius.

If you open the LBL file you can see some detail used for calculate the map. The script show this date

If you need more information, ask me.

VB

ps
The files that you need for the moon, for example, are these:

The file JP2 it’s a Jpeg2000 file that you can use for normal map.

for the first blend file o got manh vars at top see pic
http://cid-348ad7d85dee0c79.skydrive.live.com/self.aspx/picgen1/z2.JPG

now i got the IMG and LBL4 files for the moon to start

npw i got the importa blend file
and i get a lot less vars then in the first files

just 2 words

for the moon4 file i have
and it’s beginning to read the file

but even that one is not working i get an error on an aray laterat line 84 in the program!
what can i change to make it work ?

Thanks

Ok, we are near. Your pic is correct but the windows is too little, You must expand the window (you can use right CTR+UP arrow),
When you start the script in the windows you can see only the Select button, the word Message and more upper the word Parameter
Then click on Select, select the IMG file, not LBL, If is OK, under the word parameter appear some controls and some labels.
Select the coordinate (for example from top to bottom 3, 0, 10 and 20
then click on Exec

If there isn’t too much point is immediate,

Here you can see the window script after you have selected the file.

only as shown on the pic wiht only 2 words?
Yes

Use the blender file in Pasteall.org : http://www.pasteall.org/blend/2859

IMPORTA MAPPE.blend

But is important that you keep the window of the script more high as possible (at least 700 pixel)

the path seems to be good but no error in the console output only
on screen at message line in middle of screen!

copy of the file LDEM4 for the moon
http://cid-348ad7d85dee0c79.skydrive.live.com/self.aspx/picgen1/LDEM^_4.IMG

and LBL
http://cid-348ad7d85dee0c79.skydrive.live.com/self.aspx/picgen1/LDEM^_4.LBL

try it with these files don’t know may be something wrong with theses!

i got theses file form the given moon site

hope it can work cause it seems very intersting

Thanks

I tried your file and are OK. You have the 2 file in the same directory? Because that message appear when the script don’t find the LBL file.

Ciao
VB

19

yes the 2 files are in the same folder

but why it does not find the LBL file t ?
i mean is there something wrong with the name may be ?

i tried it again in other folder for the 16 files and get the same error

i printed the file name and i g et this for LDM
at line 158

print ’ filename ext =’,FileAndExt[0]

Checking for installed Python… got it!
filename ext = C:\Users\RJ\0blend25\0aplha29061\2

so looks like it’s not getting the right name for this file i think

Thanks

20

sorry forgot to add teh full name

but the LBL name is not right here i think
here is the full name for the LBL file

filename ext = C:\Users\RJ\0blend25\0aplha29061\2
filename ext = C:\Users\RJ\0blend25\0aplha29061\2
filename = C:\Users\RJ\0blend25\0aplha29061\2.LBL

why is name = 2.LBL ?

Thanks
