GIS 2go - Frequently asked questions (FAQ)
Which devices are supported by GIS 2go?
GIS 2go has been optimized for use on tablets and smartphones.
Which hardware do I need to run the GIS 2go Add-in?
The add-in runs on all hardware that is supported by the ArcGIS Desktop System. For a highly performant export of your mobile map we suggest a PC with the latest multicore processors and Solid State Disk (SSD).
I can't find the GIS 2go App in the Google Play Store. What are the minimum requirements for running the app?
Your tablet needs to meet the following requirements:
- Android 4.0 or higher
- "xlarge" screen
Hinweis: "xlarge" screen is a Google definition. xlarge screens are at least 960dp x 720dp, where “dp” are “device independent pixel”. You can convert your actual resolution to dp using a formula: dp = px / (dpi / 160)
Example: For the Nexus 7 (1280px x 800px at 216 dpi) this means:
dp = 800 / (216 / 160) = 592
This means that the Nexus 7 is not considered an “xlarge” device.
As a rule, all Android 10 inch tablets are supported.
The following devices are currently not supported: Nexus 7, Samsung Galaxy Tab 1 (Modell GT-P7500), Galaxy Note 8.0
Where can I save my map without using the cloud?
The mobile server can also be hosted on-site using your own infrastructure. Please contact us for more information and an individual offer.
How can I save my map if there is not enough storage space available in the cloud?
You can extend storage space by upgrading your account. Please contact us for more information.
Where will my mobile map be saved?
Mobile maps are exported to the mobile server and will additionally be saved to a local folder. In the GIS 2go Add-in you can change the path to this folder.
Why does the map export take a longer time than expected?
When you export a map, image files (tiles) for every selected layer in every selected scale range for the current map extent will be created. In other words, an image pyramid is generated for each layer. The data volume and therefore also the duration of the export increases exponentially with each additional scale range. In addition attributes, media attachments and further metadata are extracted and also added to the mobile map.
How can I minimize the duration of the export process?
The duration of the export process depends on the following factors:
Number of layers
- Only export layers you will really need on the go.
- Group layers that don’t need to be displayed as a single layer.
- Save layers that you need in multiple maps in an extra map.
- This prevents commonly used data from being exported multiple times.
Maximum scale range
- Choose the smallest possible maximum scale range.
Number and size of the attached media
- Keep the file size of the attached media small.
Use data sources that are saved locally on your PC and use a Solid State Disk (SSD)
- Optimally the data to be exported should be available on your local machine and you
- should use the fastest possible storage medium (for example SSDs).
- The higher latency of online services will slow down the export process.
What impact does the size of a mobile map have on the performance of the app on your tablet?
Only the number of layers has an impact on the performance of the map on the tablet. The scale range and the size of the map do not have any impact. Please note:
- The larger the file, the more time the export process takes.
- Be aware that during the export process the mobile map needs at least 2.5 times more space for temporary storage. In addition to the map itself, you will need roughly the same size again as free space during the import process
- Downloading larger maps from the server takes longer than downloading maps with a smaller file size.
How do I transfer maps via USB cable to my tablet?
If there is no connection to the Mobile Server your map will only be exported to your local maps folder from where you can transfer it via USB cable to your tablet. Connect the tablet to your PC.
For Android: : Copy the map from your local map folder to the folder “CadenzaMobile” on your tablet.
For iOS: You can use iTunes to transfer the map. Open iTunes, click on the connected device and go to the “App” tab. At the bottom of the page select the app “Cadenza Mobile GIS 2go”. In the list on the right you can see the data of the app. Click on the “Add” button and select your map file. We recommend using a program like iExplorer (Link: http://www.macroplant.com/iexplorer)) to transfer maps since it can access the filesystem of your iPad directly and is generally faster. Copy your map to the “Documents” folder inside the app folder.
In the app: Tapping on the “Import” button will import the map you just copied to your device and add it to the map list.
Where do I modify the export limitations?
How many network based data sources can I use?
For longer map exports we recommend using as few network based data sources as possible. They are typically less reliable and performance of local data sources is usually better.
Does GIS2go support base layers for the export?
Yes, as long as they are inside a basemap container.
Are password protected layers supported by the GIS 2go Add-in?
No, the GIS 2go Add-in is not allowed to export password protected layers. This is a restriction of ArcGIS. If the desktop map includes password protected layers a warning is displayed. The user has the option to save a copy of the map without those layers. This map can then be exported.
For more information about password protected layers in ArcGIS, please go to http://forums.esri.com/Thread.asp?c=158&f=1702&t=255435
What impact does the Arc2Earth Add-in has on on GIS 2go?
According to recent user feedback, there is an interaction between the GIS 2go Add-in and the Arc2Earth Add-in (http://www.arc2earth.com/). In this combination, ArcGIS will crash at the end of the map export process. Currently the only solution is to deinstall Arc2Earth or to use separate ArcGIS installations for both Add-Ins.
What happens when I deinstall GIS 2go?
For iOS: All data in the documents folder will be deleted.
For Android: All maps and exported map changes will be untouched. Only the local database of the App will be deleted. This includes all changes that have not been exported yet.
Why does ArcGIS crash during the export?
You may have too little memory available. To resolve this problem we recommend reducing the amount of layers to export or to use a Windows 64-bit version so that more memory can be allocated.
Where do I find the log files for t he GIS 2go-Add-in?
An error message concerning nested group layers appears. Why am I not allowed to export the map?
The Add-in supports only one level of grouping. If your map includes group layers inside other group layers an error message appears in the export dialog. To export the map, make sure that there are no nested group layers in the map or deselect them in the export dialog.
Where can I find information about the version of the Add-in?
In the ‘Info’ tab you can find all necessary information about your current GIS 2go-Add-in version and build date. This information might be helpful in case of troubleshooting.
Why is it not possible to establish a connection to the Mobile Server?
Access may be prevented by your firewall. The host cadenzamobile.env.disy.net needs to be reachable on port 443
