Terrain Elevation Geometry Sources
CivilGEO’s engineering software can utilize elevation data for creating and generating:
- Terrain surfaces
- Cross sections
- Roadway crossing high chord geometry
- Inline structure weir crest geometry
- Lateral structure weir crest geometry
- Flood maps
Elevation Grid Data
Our software supports most major elevation grid data file formats, such as:
- ArcInfo ASCII Elevation Grid
- ArcInfo Binary Elevation Grid
- ArcInfo Float Grid
- ENVI BSQ Band Sequential Grid
- ERDAS ER Mapper Grid
- ERDAS Imagine Grid
- GeoTIFF Elevation Grid
- Intergraph Raster Grid
- JPEG 2000 Elevation Grid
- USGS DEM Elevation Grid
- USGS NED Elevation Grid – BIL Format
- USGS NED Elevation Grid – Float Format
Other Elevation Data
Other elevation data files can be processed within the software to create an elevation terrain surface. This includes:
- ArcInfo Contour Shapefiles
- ArcInfo Elevation Point Shapefiles
- ArcInfo GDB File Geodatabases
- ArcInfo MDB Personal Geodatabases
- AutoCAD Civil 3D Terrain Surfaces†
- AutoCAD Contours
- Bentley MicroStation Terrain Surfaces†
- Bentley MicroStation Contours
- LandXML Formats
- LIDAR Point Cloud Formats
- XYZ ASCII Point Terrain Data
- 2DM files
Adding Elevation Data
Refer to this article in our knowledge base on how to add elevation data as well as how to construct an elevation terrain surface from online elevation data sources or through a local elevation data file.
