Because Global Mapper Mobile is intrinsically connected with the desktop version of the software, all of the supported file formats as well as map layers originating in a spatial database or Web Map Service can be embedded within a Global Mapper Mobile Package (GMMP) file for transfer to the device. All data will retain the display and rendering characteristics that were applied in Global Mapper.
All data displayed in Global Mapper Mobile is prepared in and exported from the desktop version of the software as a Global Mapper Mobile Package file. There are several options for transferring this file to the device:
Field-collected data is first saved locally as a GMMP file, which can subsequently be transferred back to the desktop software using any of the above methods.
Global Mapper Mobile utilizes your device's GPS functionality to provide real-time location information as well as location-specific data collection capability. During the initial installation, you will be asked to grant permission for the application to use you device's location data and, while some of the basic operations of the application will be available without this capability, is strongly recommended that you enable this service.
One of the more powerful components of the application is its data collection capability, which can entail a variety of workflows from simply recording a point based on the current location to filling out a preconfigured attribute form with pick lists, required fields, and other attribute elements. The advanced data collection process begins in the desktop software where a template layer can be created to define the field data collection requirements. This layer is then transferred to the device within a GMMP file.
Global Mapper Mobile offers a complete suite of field digitizing tools for manually creating or editing points, lines, and area features on the device. Several options are available for creating points or sequential vertices based on manually tapping the screen, on the GPS location, or on a defined time or distance increment while moving. The editing function allows individual points or vertices in a line or area feature to be inserted, moved, or deleted.
One of the most powerful point management tools in Global Mapper Mobile is the option to assign a photo from your device's internal camera or photo library to the current GPS-derived location. Not only will this image be tagged on the device, but the association with the tagged location will be retained when the GMMP file, including any associated photos, is transferred back to the desktop version of Global Mapper.
Sometimes referred to as situational awareness, the GPS functionality on your device allows you to display your current location and progress in relation to any loaded data. Beyond simply referencing your movement against a traditional street map, this allows you to navigate to features or assets that are not as apparent. For instance, you can monitor your progress on a geological map to ascertain what landforms or bedding planes are present under foot.
Comparable to the Overlay Control Center in the desktop version of Global Mapper, the mobile edition offers an efficient layer management tool in which loaded layers can be turned on or off or can be reordered to expose features from an underlying layer. The Overlay Control Center also provides access to the metadata for a selected layer.
