Hi M1013828,
I think we have all the required pieces together now.
I think the first thing you need to do is bake the roads shapefile into a large RGB bitmap, where the roads are one defined colour and everything else is some other colour. The bitmap must be exactly the same dimensions as your attributes map.
Next, you'll need to download and install L3DT Pro v2.9 build 10, which includes an updated attributes map importer plugin. The installer is on the pro downloads page now (consult your sales/registration receipt e-mail).
Next, you'll want to copy a backup of your attributes map somewhere, in case this all goes south on us.
Then, you'll need to create a text file containing the following data:
- Code: Select all
R, G, B, Climate, Land type
90, 70, 80, "Artificial", "Asphalt",
Please set the R, G, B colour values to the colour of the road in your bitmap, and save the file somewhere with a '.txt' extension.
Finally, in L3DT, with your project loaded, select the '
File->Import->Attributes map->From colour map with palette file' menu option. This will then ask you for the filename of the bitmap image and the palette text file. Thereafter, it should load the image and bake just the road onto your existing attributes map.
Please let me know if you find any problems.
Cheers,
Aaron.
