MapBrowser Basic export allows you to export an Area of Interest (AOI) as a single JPG image. You can also export the imagery as a georeferenced file with the Basic export.
Exporting as a single image
- Start the export.
- Select the Export type as Basic.
- Complete the steps described below.
Selecting the area to export
Navigate to the area you would like to export and re-position it if it's required.
Selecting the resolution
Specify a resolution in meters per pixel. Choose the resolution you want for the exported image. The available options are determined by the size of the box you define. The estimated file size is displayed in the Summary section.
The resolution that you should choose depends on the zoom level at which you want to export the AOI.
NOTE: If the area you have defined is too large for the highest resolution you will see the message "For a higher resolution please define a smaller area." This tool permits saving of images at extremely high aspect ratios, which can be very useful when saving along transportation routes.
- You can use high resolution options for 2D (vertical) imagery only
- Rotated imagery cannot be exported in high resolution, instead the imagery is exported in its original orientation
NOTE: Annotations and measurements are not included in the exported high resolution image.
There is a system limitation to maximum image size, which varies by coordinate system. For the default Web Mercator coordinate system, this limit is 50 megapixels. Due to the way local map projections are rendered, the maximum image size for locally projected imagery may be lower than 50 megapixels.
Exporting to a georeferenced file
Exporting georeferenced files is very useful when you want to use an image in third-party applications, such as ArcGIS or Autodesk.
To export the content to a georeferenced file, select Include georeferenced file. The georeferenced file will be saved as a .JGW file.
Viewing the export summary
Once you select all the options, you'll see the export summary with the following information:
- Width of the image in pixels
- Height of the image in pixels
- Estimated file size of the image and georeferenced zip file
The estimated file size is a very rough estimate with respect to the maximum file size that will be downloaded. The actual size will often be much lower because it is difficult for us to estimate image compression efficiency in advance.
Reviewing your export
Click REVIEW EXPORT to view more details of your export. The Export Summary dialog is displayed where you can specify a name for the export. This name will be displayed in the DOWNLOADS window.
Downloading the files
Click CONFIRM EXPORT to start preparing the download.
The DOWNLOADS window is displayed with the progress of your download.
If you chose to create a georeferenced file, that is saved as JGW.
NOTE: The JGW georeference file has the same filename as the image file, and its name must always match that of the JPG. The filenames follow this format: <export type><file format>.zip.
You can import the image and its JGW to any application that supports georeference files. Examples are AutoCAD Map 3D or Civil 3D, ArcGIS, ArcMap, MapInfo and QGIS. See the article on using a georeferenced image for more information.
