Get Online Maps

Get Online Maps Dialog

The Get Online Maps button allows a user to select online data from a variety of different sources. Once online maps has been selected, the data resolution will be automatically adjusted based on the zoom parameters. Online maps can only be viewed in plan view.

Online maps are raster datasets that can contain imagery, elevation, or land use information. If online maps is available, the user can right-click on each of the maps to convert them to static images that can be saved to the local hard drive. A user can convert or interpolate online maps containing elevation data to various elevation formats.

Note that online data sources are on external servers that we have no control over. The data may draw/export very slowly or become unavailable at any time. We have no control over this.

The Advanced button allows you to select from other data sources and to use other online data query functions that may not be fully supported. In the Advanced dialog, the Add Sources From File button allows you to add new Web Map Service (WMS) sources from an external text file.

Exporting to a File

An online map can be exported to a file and loaded into the project. A user may want to do this to save a local copy and not be dependent on internet access. Also, there may be more commands and options available with a local file, such as interpolation or conversion to other object types, than with online maps.
