Using this command images can be imported from major service providers (Google, Bing, Yahoo, Ovi) in different resolutions (Normal, medium, high, highest) and image modes (satellite, map, hybrid) in full color or grayscale in major image formats (BMP, JPEG, TIFF). This command is intended to be used when a map or image is needed to be inserted in a drawing to show the site location with no scale and without having to georeference the drawing first.
Dialog box settings:
·Save image files automatically. If you select this option, image files will be saved in the CAD-Earth Images folder automatically assigning a consecutive file name.
·Select where to save image files. A file selection dialog box will be shown where you set the file name and folder where the image will be saved.
ØImage capture. Image can be imported in full color or in grayscale.
ØImage format. Available image formats are: BMP, JPEG an TIFF. Use the JPEG format if you need to reduce the imported image file size to the maximum possible.
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 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.
·Highest. Up to sixty four image tiles.
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).
·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.
ØGeolocate selected polyline. Select to place the closed polyline initially selected in a map to define its geolocation. A map will be shown where you can insert, move, rotate an scale the polyline until it is correctly placed.
ØSave georeference parameters to file. A file selection dialog box will be shown to save a DGW text file containing conversion parameter values.The georeference parameters are translation, rotation , scale and EPSG ID.
ØSave georeference parameters in current drawing. Select if you wish to georeference the current drawing and use the parameters defined to convert between drawing and latitude/longitude coordinates by other CAD-Earth commands.
·The same image mode you select (satellite, map, hybrid) when geolocating the polyline will be used when the image tiles are processed.
·Select normal resolution to get the same map image as shown on screen. Text and symbols will appear smaller if you select a higher image resolution when importing a map.
·To select the resulting 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 most CAD programs. 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 intend to share the drawing where images were attached choose the 'Select where to save image files' option. That way, you can easily locate the corresponding image files to include with your drawing file.
