Import geoimage

Toolbar:

Menu: CAD-Earth > Import geoimage

Command line: CE_IMPGEIMG

Prompts:

Select closed polyline:

CAD-Earth version: Basic, Plus, Premium.

Command description:

Using this command images can be imported from major service providers (Google Earth, Google, Bing) in different resolutions (normal, medium, high, highest) and image modes (satellite, map, hybrid) in full color or gray scale in major image formats (BMP, JPEG, TIFF). Images can be clipped inside a closed polyline.

Dialog box settings:

Dialog box to import geoimage

ØImage file path.

•Relative path. The image file must be saved in a subfolder or in a parent folder relative to where the drawing file is saved.

•Full path. Image file will be saved in the folder selected.

•No path. The image file must be saved in the same path as the drawing or in any AutoCAD support file path.

•Create world file. A plain text data file used by geographic information systems (GIS) to georeference raster map images will be created. This file will be saved in the same folder as the image file.

ØImage capture. Image can be imported in full color or in grayscale.

ØImage resolution. Image tiles are processed and joined together to increase image detail, covering the closed polyline extents. If the maximum zoom level is reached after subdivision the number of tiles will be adjusted to the maximum allowable. The maximum number of image tiles processed according to image resolution are:

•Normal. One image tile.

•Medium. Up to four image tiles.

•High. Up to sixteen image tiles.

•Higher. Up to sixty four image tiles.

•Maximum. Up to 256 image tiles.

ØImage type.

•Satellite. Plain aerial image with no additional information.

•Map. A diagrammatic representation showing artificial features with text annotations.

•Hybrid. An aerial image with map information and text annotations.

ØService provider. You can choose from the web service providers Google Earth, Google or Bing. Some service providers offer more updated images than others with higher or lower resolution. Google generally have the fastest service and higher quality imagery.

ØMargin around image. Percentage image increase to show more image information around the polygon extents. For example, a 5% margin increases the image extents by 10% in the horizontal and vertical direction (10% for the left an right margin and 10% for the top and bottom margin).

ØWaiting seconds between screenshots. Increase this value if the image tiles in the final image are not aligned properly.

ØShow percentage progress bar. Uncheck this option if the percentage progress bar is shown in the final image.

ØImage clipping.

•Clip image. Image will be clipped inside the closed polyline.

•Hide image frame. If the image frame is not visible it will not be printed but the image can't be selected. To turn on the image frame, set the IMAGEFRAME variable to ON (1).

•Curve smoothness. If the closed polyline has curved sides they will be converted to straight segments before the image is clipped. The number of resulting segments will be proportional to the maximum segment length and the maximum deflection angle between consecutive segments specified. If the image will not be clipped or if the closed polyline doesn't have curved segments this option will have no effect.

ØImage transform.

•Rotate image. Image will be scaled and rotated when inserted to fit the polygon area. The image resolution will be as captured on screen.

•Skew image. Image will be skewed and scaled to better fit the image to the polygon area. The image will appear with a slight blur due to the transformation.

ØSave image within drawing. If this option is checked, binary information from the image file will be saved in the drawing. If the file is not found when opening an image, a new file will be created reading the binary data in the drawing and stored in the CAD-Earth's Images folder.

ØScreen scale factor. This value is calculated automatically. Adjust this value if you see gaps between image tiles.

Tips:

•The current drawing must be georeferenced before using this command.

•To import an image to AutoCAD you must select an existing closed polyline in the drawing where the image will be placed.

•To select the image for editing you the image frame must be visible. To turn on image frame visibility set the IMAGEFRAME variable to ON (1)

•Images are managed as external references in AutoCAD. If you intend to share a DWG where images are attached you must also include the image files, so the image references can be updated. You can use the IMAGE command to manage image references.

•If you select the relative path option you don't have to recreate the image file path in another computer as long as the image files are included in the same folder as the drawing or in a relative folder.

•The drawing must be saved first before you select the relative path option otherwise the image will be created with full path applied.

•If you select the no path option you must save the image file in the same folder as the drawing or in an any AutoCAD support file path.

•Use the insert geoimage command instead if you don't need the image to be georeferenced in the drawing.
