Supported External Data Formats

Our software can utilize a variety of external data, such as:

  • AutoCAD and AutoCAD Civil 3D Drawing Files (*.dwg, *.dxf)
  • Bentley MicroStation Drawing Files (*.dgn)
  • AutoCAD Civil 3D and Bentley MicroStation Terrain Surfaces (via LandXML)†
  • 3D Models (via SketchUp)
  • Elevation Data (numerous formats detailed below)
  • GIS Data (*.shp, *.gdb, *.mdb)
  • Survey Data (numerous formats detailed below)
  • Raster Imagery Data (numerous formats detailed below)

CivilGEO’s products also supports model data such as:

  • HEC-RAS Projects (*.prj)
  • HEC-HMS Projects (*.hms)

Elevation Data

Elevation data can come in a variety of different formats. The following elevation data file formats are supported:

  • ArcInfo ASCII Elevation Grids
  • ArcInfo Binary Elevation Grids
  • 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
  • GeoTIFF Elevation Grids
  • LandXML Terrain Models
  • USGS DEM Elevation Grids
  • USGS NED Elevation Grids – BIL Format
  • USGS NED Elevation Grids – Float Format
  • XYZ ASCII Point Terrain Data
  • LiDAR Point Clouds (*.las, *.laz)

GIS Data

GIS data consists of two components:

  • Spatial Data: This component contains coordinate information that describes the element. For example, this could be a manhole location.
  • Attribute Data: This component is used to store information about the element. For example, this could be the manhole invert and rim elevations.

The following GIS data file formats are supported:

  • ArcInfo Shapefiles
  • ArcInfo GDB File Geodatabases
  • ArcInfo MDB Personal Geodatabases

Survey Data

Survey data can be used to import alignments, cross-section geometries, terrain surfaces, and much more.

The following survey data formats are supported:

  • AutoCAD 3D Points
  • AutoCAD Civil 3D COGO Points
  • ENZ (Easting, Northing, Elevation) Point Files
  • ENZD (Easting, Northing, Elevation, Description) Point Files
  • NEZ (Northing, Easting, Elevation) Point Files
  • NEZ (Northing, Easting, Elevation, Description) Point Files
  • PENZ (Point, Easting, Northing, Elevation) Point Files
  • PENZD (Point, Easting, Northing, Elevation, Description) Point Files
  • PNEZ (Point, Northing, Elevation) Point Files
  • PNEZD (Point, Northing, Easting, Elevation, Description) Point Files
  • XYZ ASCII Point Files

Raster Imagery Data

In its simplest form, a raster imagery file consists of a matrix of cells (or pixels) organized into rows and columns (or a grid) where each cell contains a color value. Rasters can be digital aerial photographs, images from satellites, digital pictures, or even scanned maps.

The following raster imagery data file formats are supported:

  • Bitmap (*.bmp)
  • ERDAS IMAGINE (*.img)
  • GeoTIFF Georeferenced TIFF (*.tif, *.tiff)
  • Intergraph Enhanced Compression Wavelet (*.ecw)
  • JPEG 2000 (*.jp2, *.j2k, *.jpg2)
  • JPEG (*.jpeg, *.jpg)
  • MrSID (*.sid)
  • Portable Network Graphic (*.png)
  • TIFF Tagged Image File Format (*.tif, *.tiff)
