TerraLand

TerraLand plugin contains of multiple components which use GIS data & coordinates to load & create Photo-Realistic Terrain from any part of the Earth within a few clicks.

The package is Unity 5.x & Unity 4.x compatible.

​

Connects to ESRI Elevation & Satellite Imagery servers and download needed data for user defined area of interest along with many other options to adjust resolutions and other settings.

• Global Elevation & Satellite Imagery support for downloading
• Highest available Elevation data resolutions ranging from over 30 meters in most of the Earth areas to approximately 3 meters in some limited areas. More Info
• Highest available Satellite Imagery provides 1 meter or better Satellite and Aerial Imagery in many parts of the world & lower resolution satellite imagery worldwide. More Info
• Bathymetry data included to create above & below (negative values) sea-level heights mixed for the final heights. More Info
• Multi-Threading operations for faster & synchronous job handling
• Create, update & edit terrains right within the scene
• Multiple or single terrain chunk support for both Elevation & Satellite Imagery
• Built-in Geo-Coder to search any location on Earth
• Built-in Interactive Map can preview selected area using Google, Bing, OpenStreetMap, MapQuest, MapBox & Yandex with 35 style variations
• Analysis Maps Downloader can get terrains’ Slope, Aspect, Hillshade & Elevation maps up to 8192 resolution on the fly
• User-Friendly area definition by real-world metrics or geo-coordinates
• Heightmap/Elevation data downloader with complete resolution flexibility & other various options More Info
• Satellite Imagery downloader with lots of options to define resolution quality & import settings More Info
• Save Elevation & Imagery data for later usage in projects or external GIS software
• Can save elevation data in 3 formats of ASCII Grid, Raw & Tif along with projection (.proj) files
• Satellite Images will be saved in Jpeg format with compression quality modifier
• Automatic failed images downloader due to connection drops during the downloads
• Predefined resolution presets for elevation & imagery to automatically set final terrain quality
• Generated Terrain(s) can have up to 8192 heightmap resolution to override Unity’s limitation and achieve high resolution terrain surfaces
• Each downloaded Satellite Image/Texture can have up to 4096 resolution and unlimited resolution for the entire terrain(s) as much as GPU can handle
• Elevation/Vertical Exaggeration modifier to set final heights. TerraLand automatically rescales terrains based on Real-World area size (value of 1)
• Preset Management to save any user adjustments made in the UI
• Run-Time “Terrain Neighbors” script to handle terrain neighboring during the gameplay

A collection of multiple operations needed for terrain management in the scene.

• Loads any previously downloaded elevation data files of ASCII, Raw & Tif
• Applies elevation data to new or existing terrains regardless of the data resolution or terrain(s) resolutions through complex resampling operations
• Sets terrain neighbors if lost or doesn’t exist at all for seamless LOD & Tessellation between terrain chunks
• Splits selected single terrain to the user defined grid size
• Smoothen out terrain heights if there are jagged edges on the surface
• Exports elevation data in 2 formats of ASCII & RAW from the selected terrain(s)
• Image Tiler which takes a folder containing satellite images in project and textures corresponding terrain(s) More Info
• Terrain To Mesh converts selected terrain(s) to mesh and optionally places it in the scene
• Mesh To Terrain takes a 3D model/mesh and outputs a terrain with selected resolution in the scene
• Converts DMS (Degree, Minute, Second) to DD (Decimal Degrees) coordinate systems and vice versa

A newly introduced component to do image processing on satellite images and maps. It takes a satellite image and outputs 3 map types of Shadowless map, Colormap & LandCover (Splatmap).

• Shadow Remover can remove shadows from the Satellite Images through complex image processing operations
• Colormap Generator can remove small details from the Satellite Image and generates a colormap
• LandCover Generator Filters top used colors in the image and generate a landcover/splatmap from the image
