renato.semadeni Posted January 16, 2015 Share Posted January 16, 2015 Hi there I'm trying to combine two existing landscape into a single one. Is there a possible approach to this? Kind regards, Renato Link to comment
silent Posted January 16, 2015 Share Posted January 16, 2015 Hi Renato, I'm afraid this is not a trivial task and it is not possible to do this out of the box. It should be OK to have 2 landscape nodes in world. Could you please give us more information about your use case? Thanks!

renato.semadeni Posted January 19, 2015 Author Share Posted January 19, 2015 Hi Andrey Lets say a supplier delivers us an improved version of a certain area, landscape, models, etc. But we already have this area in a wider landscape. We would now import the improved into the existing one... For example: the Washington landscape from last year includes as well the Port Angeles area. If we would like to exchange the existing area in Washington with the one from Port Angeles. Is this understandable? =) Renato Link to comment
unclebob Posted January 20, 2015 Share Posted January 20, 2015 Hey Renato, glad you're asking such cool questions! The whole "merge process", let's call it that, is critically depend on data your supplier provided to you. If we're talking about engine friendly format (prepared heightmap, diffuse/specular/normals tiles & materials, terrain node file, custom content in .mesh format, etc.) then it might be a hell of a job to merge it or change parts. I'm not saying it's impossible as in some cases you can just delete old "terrain cells" and replace them with new ones; in other cases it's possible to add new data just as another terrain, that's it. But better way is to use raw data to prepare & merge it in external terrain editors such as WorldMachine. After that you'll have to export merged data to engine friendly format and use our Landscape plugin to recreate whole landscape in the engine. That'd be the way if you want to merge Port Angeles and Washington. We though about developing such terrain toolset (geotiff, raw terrain data, area of interest with detailed data support, etc.) built into the engine but that'd take at least a year in development.

renato.semadeni Posted January 21, 2015 Author Share Posted January 21, 2015 Hi Andrey I hoped for a merging tool =), but I see there would be an imense amound of development. I see the approach to merge the heightmap and create updated diffuse/specular/normal maps in WorldMachine. I think the same count for the land use data (such as coasts, forest, streets,...)? Would you provide the raw data of washington and port angeles for testing such an approach? Thanks a lot, Renato Link to comment
unclebob Posted January 21, 2015 Share Posted January 21, 2015 Renato, That'd more than 50 gb space so I recommend you to get raw data from public domain, like this one: http://maps.ngdc.noaa.gov/viewers/wcs-client/ Link to comment
renato.semadeni Posted January 22, 2015 Author Share Posted January 22, 2015 Thanks for the help and for the link and yes I will try it with this one! Link to comment
