GeoTalks Express – Session 5 Questions & Answers

The fifth of Blue Marble’s GeoTalks Express online webinar series, entitled Get Outside with Global Mapper, was conducted on May 13th, 2020. During the live session, numerous questions were submitted to the presenters. The following is a list of these questions and the answers provided by Blue Marble’s technical support team.

The Global Mapper Mobile knowledge base links below are to the Android version of the help pages. Although the two versions of the app contain the same functions, an iOS-specific version of the knowledge base is available here.

 

I want to know if with my license desktop, I can register a Global Mapper Mobile Pro?

​Is it the same to register the desktop version and mobile version?​ I mean if I register in desktop, can I use the Pro version in Global Mapper Mobile?

The Global Mapper Mobile app is free to download and use, but to register the Pro Module for the app you need to purchase a license. The Global Mapper Mobile Pro license is separate from the Global Mapper desktop license. You can purchase a license here on the Blue Marble website, or by contacting the sales team at orders@bluemarblegeo.com.

 

When adding a point, is there an option that allows you to take and attach a picture right there in the same window?

After tapping to add a point feature, at the bottom of the New Feature screen use the small picture icon option in the bottom right corner to add a picture to the digitized point feature. 

 

Can you cover adding photos and if those photos can later be sent to a kmz file?

In Global Mapper Mobile you can add photos to a map. You can link a photo to a digitized or existing vector feature from the Feature Edit screen, or you can add a photo directly to the map and it will be added as a picture point at the geotagged location of the photo. Since the photos taken with a mobile device do not have full georeference information they are all added as file links. 

After exporting your map from Global Mapper Mobile and sharing it to your computer, bring the Global Mapper Mobile Package file (*.gmmp) into Global Mapper desktop. From here you will be able to export layers of vector features to KML/KMZ format in such a way that the photos linked to the features will be displayed in the feature info popups seen in Google Earth. 

 

It is hard to see the measure tool against the aerial background. Can the color of the tool be changed?

The line added when measuring is a black line highlighted in yellow. Is this the part of the tool you are having trouble seeing?

The crosshair symbol used by the measure tool is grey by default, but the color of this symbol can be changed in the App Configuration

 

Will GMM be suitable for Android, iOS and Surface?

Global Mapper Mobile is available in the Google Play Store and the iOS App Store making it suitable for Android and iOS devices. The Global Mapper Mobile application cannot be run on a Microsoft Surface computer as that device is a Windows-based laptop, not a mobile device like a tablet or phone. You can run the Global Mapper desktop program on a Microsoft Surface laptop. 

 

Can we see real time field data collection activities via Global Mapper Desktop?

Data collected in Global Mapper Mobile is stored in the map in Global Mapper Mobile and cannot be streamed to Global Mapper desktop. To transfer collected data you would need to export the map and share it to your computer to then open the file in Global Mapper desktop.

In Global Mapper desktop you can set up a direct connection to an external GPS device in order to collect field data tracks in Global Mapper desktop.

 

Can we use a tiff file in the Global Mapper Mobile app?

Global Mapper Mobile does not support the import or export of TIFF files. Without the Pro Module the app will load and export Global Mapper Mobile Package format (*.gmmp) files. With the Pro Module the app will also import GeoPDF files and GeoPackage files. 

You can load TIFF files into Global Mapper desktop, and from that program export the layer to Global Mapper Mobile Package format to share and load into Global Mapper Mobile. 

 

How well does the mobile app work on an iphone or will I need an ipad?

Global Mapper Mobile works on Android and iOS phones and tablets. The only difference using a tablet versus a phone would be the screen size on the device, the app will function the same on both devices. 

 

We will get to this later but what about rest services? 

With the Pro Module in Global Mapper Mobile you can add custom online sources. Esri RESTful/Google Maps Tiles, OSM, WMS, and WMTS types are all supported. There is currently no support for feature services in Global Mapper Mobile. You can access feature services in Global Mapper desktop and export the needed features to Global Mapper Mobile Package format (*.gmmp) to then work with in Global Mapper Mobile. 

 

Is it possible to add data on the Pro version of Global Mapper Mobile through a script?

Global Mapper Mobile does not support Global Mapper script like Global Mapper desktop. You can use Global Mapper script in Global Mapper desktop to add data to a workspace, and export data to Global Mapper Mobile Package format (*.gmmp). This file can then be transferred to your mobile device and loaded in Global Mapper Mobile. 

 

Can Global Mapper Mobile support Garmin GPS Devices?

If the Garmin GPS device can be paired to the mobile device with bluetooth, and Garmin supports the device in a Garmin GPS companion app, you should be able to use the external GPS for data collection with the Global Mapper Mobile app. 

General Information on using an External GPS with Global Mapper Mobile:

Using an external GPS device with Global Mapper Mobile would be using the GPS to replace the location services information for your phone/device. To use an external GPS device you will need a companion app for the GPS to receive the data stream and push the location information into Global Mapper Mobile. 

To set this up, first turn on and connect your GPS device using bluetooth and the companion app that will read the information from the GPS device. This companion app, typically made by the makers of the GPS device, should allow you to see when the external GPS is connected as this is not yet indicated in Global Mapper Mobile, but we are working on an interface to see this information right in the app. With the GPS device connected in this way, the external location data should replace the internal location data and be read into Global Mapper Mobile. 

 

How big are the files you send as Global Mapper Mobile Package (*.gmmp) files?

The file size of Global Mapper Mobile Package (*.gmmp) files depends on the data you are sending in this format. More layers, larger datasets, and higher resolution data will result in larger files. 

 

Is there any 3D functionality in Global Mapper Mobile as there is in Global Mapper desktop?

With Global Mapper Mobile being designed to work on smaller and less powerful mobile devices, there is no 3D view functionality. You can have 3D data, like elevation grid layers, loaded into the app via a Global Mapper Mobile Package (*.gmmp) file, but you will only be able to view the data in 2D. 

 

Can you navigate to a point like a forest inventory plot with this app?

With the Pro Module of Global Mapper Mobile the app can display the distance and bearing from the GPS location to a selected point feature. You can select a point feature with the digitizer tool, and enable the distance and bearing in the GPS section of the app configuration

 

Can you get data off of your MangoMap account into the Global Mapper Mobile app?

MangoMap does not yet support streaming data from a map as an online source so you are unable to stream data from a MangoMap to Global Mapper desktop or Global Mapper Mobile.

If you have the source data you used to create your MangoMap, or you are able to download data layers from your MangoMap account, you can open those layers in Global Mapper desktop and export them to a Global Mapper Mobile Package (*.gmmp) for use in Global Mapper Mobile. 

 

Can one edit a point or vertex position once clicked?

Yes, you can edit the location of a point feature or a feature vertex one the feature has been created. To do this, select the digitizer tool and tap on the feature you would like to edit, tap again on the feature to open the Edit Feature screen. Tap Vertices to see the coordinates of the vertices or the location of the point feature. Select a vertex entry by tapping on it, and tap on the digitizer tool in the bottom right corner to edit the coordinates of the selected vertex. 

 

Is the elevation value displayed at the crosshair derived from the DEM layers? Or perhaps from the street map?

The elevation value shown for the crosshair location when an elevation layer is displayed comes from the loaded elevation layer on the map. 

 

I just installed Global Mapper Mobile on my phone. I logged in and now it needs a registration code. Is that emailed?

The Global Mapper Mobile app is free to download and use, but to register the Pro Module for the app you need to purchase a license. The Global Mapper Mobile Pro license is separate from the Global Mapper desktop license. You can purchase a license here on the Blue Marble website, or by contacting the sales team at orders@bluemarblegeo.com.

To register the Pro Module on your device, you will need to login with your Blue Marble account and then enter the order number for your purchased Pro Module license. 

 

Does the Global Mapper desktop version matter when working with the Global Mapper Mobile? We are still on version 18.

While you can use the Global Mapper Mobile app with an older version of Global Mapper desktop, we highly recommend upgrading to the current release for both programs. Many updates in Global Mapper Mobile depend on how Global Mapper Mobile Package (*.gmmp) files are produced from Global Mapper desktop. Newer versions of the desktop program include updates related to the writing and loading of Global Mapper Mobile Package files, and using an older version of the program will limit the functionality of your GMMP files and the Global Mapper Mobile app.

 

Can I use feature templates without the Pro Module?

Yes, you can use feature templates as part of a Global Mapper Mobile Package (*.gmmp) without the Pro Module. You can create, manage, and add feature templates as layers in a workspace through the Configuration > Feature Template section of Global Mapper desktop. 

 

Using external GPS submeter accuracy is only available with the Pro Module?

Using an external GPS device with Global Mapper Mobile would be using the GPS to replace the location services information for your phone/device. To use an external GPS device you will need a companion app for the GPS to receive the data stream and push the location information into Global Mapper Mobile.

While you can set up an external GPS unit to work with Global Mapper Mobile without the Pro Module, the new Advanced GPS options coming in version 2.1 of the app, used to manage and monitor data from an external GPS, will not be available without a license for the Pro Module.    

 

Is there a list of GNSS pairable devices for GMM Pro 2.1?

We do not currently have a list of all pairable devices. If you have a specific unit you are wondering about, please let us know. 

 

Can the Global Mapper Mobile be used for traffic analysis?

Global Mapper Mobile is designed to take your data into the field and collect data as you wish. You can then export and bring the data back to Global Mapper desktop for further analysis. Depending on what types of data you are working with and the analysis you are looking to do, this app could be used for some traffic analysis. 

 

Can you use connected GPS accuracy augmentation tools (IE bad elf) to increase accuracy of points and other features logged within Global Mapper Mobile?

Using an external GPS device with Global Mapper Mobile would be using the GPS to replace the location services information for your phone/device. To use an external GPS device you will need a companion app for the GPS to receive the data stream and push the location information into Global Mapper Mobile. Do you know if Bad Elf produces a companion app for their devices? 

 

Is there a way to track the surveyor in Field, and also track the editing?

There is no edit tracking function in Global Mapper Mobile but you can use the Save As option to save interactions of your map as you edit it. 

 

Can you add data layers from online sources?

From the Main Menu in Global Mapper Mobile you can choose to Add Online Data Layer to stream data from Open Street Map. With the Pro Module of the app you gain access to additional built-in online sources, as well as the ability to add custom online sources and save data from online sources for offline use. 

 

What about local reference systems, like here we are working with DLT Dubai local reference EPGS:3997?

You can set the projection for your Global Mapper Mobile Package (*.gmmp) file in Global Mapper desktop. In the desktop program, set the workspace options in Configuration > Projection, and when you export your data to GMMP format select the option to Use Currently Selected Projection

With the Pro Module registered in Global Mapper Mobile, you can edit the projection parameters for a map in App Configuration

 

Is UTM available only in the Pro version?

No, you can set the projection for your Global Mapper Mobile Package (*.gmmp) file in Global Mapper desktop. In the desktop program, set the workspace options in Configuration > Projection, and when you export your data to GMMP format select the option to Use Currently Selected Projection

With the Pro Module registered in Global Mapper Mobile, you can edit the projection parameters for a map in the mobile app through App Configuration

 

Can you use pre-existing schemas from a database or layer as opposed to creating from scratch?

While you cannot create a Feature Template from an existing layer, once you have created a feature template you can save it to a template file that you can share and load into other installations of Global Mapper desktop. 

 

Can Global Mapper Mobile record tracks and routes?

Yes, Global Mapper Mobile can create point, line, or area features with the GPS methods Time Interval and Distance Interval. These methods will record a vertex or point at a specified interval tracking the movement of the user with the device. The time interval and distance intervals can be set in the GPS section of the Global Mapper Mobile App Configuration

 

Can you customize data points (waypoints) with unique icons?

Yes, as you create features and see the Edit Feature or New Feature screen, you can tap on Type to set the feature type. Each feature type built into Global Mapper Mobile is associated with a feature style that will be used to display the point, line, or area feature on the map. 

 

Mobile works without an active cellular connection?

Yes, the GPS location services will still function on a device even if it is not connected to a network, wifi or cellular. You will need a cellular or wifi connection to share data to and from your mobile device and stream data from online sources. 

 

I need help opening maps using dropbox and iOS. Please run through the process, the map wants to open locally.

 

From the Global Mapper Mobile Open Map option, you can use the button in the bottom right corner to browse your device for a map. This browse screen will show files downloaded on your device as well as files accessed through a file-sharing app like Dropbox. 

When opening a map from a file-sharing app such as Dropbox, you will need to tap for more options in a file. In Dropbox select to Export the file and when options for export appear, scroll through the app suggestions and select Copy to Global Mapper Mobile. This should launch the Global Mapper Mobile app and open the map.

 

​Is there a benefit in tiling exports to GMMP?

Tiling your export to Global Mapper Mobile Package (*.gmmp) file will break the data up into separate GMMP files, one for each tile. Tiling your data could be useful if your data covers a large area. Users in the field will be able to load and work on smaller portions, individual tiles, of the complete data in Global Mapper Mobile. 

 

Highly recommend some plus and minus buttons for zoom. Especially when starting at world view and zooming. With finger pinch zooming I took a tour of Antarctica.

I have written a request ticket about adding zoom and pan buttons that you can enable in Global Mapper Mobile to assist with navigation around a map. 

From the control center in Global Mapper Mobile, use the home button to return to the full extent of the map, or you can tap on the options for a layer and zoom to a specific layer. 

 

Would you happen to know if this app will work with Trimble catalyst gps device?

We currently have an open enhancement request to be able to connect Trimble Catalyst systems with Global Mapper Mobile.

 

Can you use an external antenna for rtk Ntrip Network?

Currently Global Mapper Mobile does not support interaction with RTK based GPS devices. We have a feature request on this issue that our development team is considering.
