The native GIS app Cadenza Mobile can be used on all current tablets and smartphones.

Recommended:

  • Main memory. 512 MB or more
  • Internal storage capacity: 32 GB or more
  • Screen resolution: 1024 x 768 or more
  • Device with GPS function and camera

How do I download the GIS app Cadenza Mobile?

The Cadenza Mobile app is available for iOS and Android devices and can be downloaded here:

iOS version: https://apps.apple.com/us/app/cadenza-mobile/id1052754530

Android version: https://play.google.com/store/apps/details?id=net.disy.cadenza.mobile.app&hl=en

Where is my mobile map stored?

When you export a map from Cadenza Desktop, it will be stored in your local user directory on your computer. It is also automatically uploaded to the Cadenza Mobile Server - if available. All mobile maps available on the Cadenza Mobile Server can be transferred directly to your mobile device.

How can I prevent my data from being stored in the cloud?

The Cadenza Mobile Server can also be operated as an in-house solution integrated into your IT infrastructure. Feel free to contact us at any time. Our team will be happy to provide you with an individual offer fully tailored to your requirements.

What can I do if my mobile map is too big to store it in the cloud?

You can request additional storage space for your account, if required. Feel free to contact us at any time. Our team will be happy to provide you with an individual offer fully tailored to your requirements. Alternatively, you can transfer the mobile map to the tablet connected via USB cable. In addition, when creating a new mobile map in Cadenza Desktop, you can select, for example, the size of the area to be exported, the display scale or the grouping of layers. This way you create smaller custom mobile maps.

What is the difference between exporting grid and vector data?

Grid data
When creating the mobile map, image files (tiles) are generated for each selected layer with the export format "grid data" for the map section in all scale ranges you selected. For each grid layer, a pyramid representation is created. The data volume and thus also the export time increase exponentially per scale level. Moreover, attribute data as well as documents and metadata are extracted and then inserted into the mobile map.

Vector data
When exporting layers with the "Vector data" export format, the data is exported to a SpatiaLite database. The signatures are transferred to an SLD file. The mobile map is rendered on the mobile device.

If layers are originally declared as vector data, we recommend that you select the "Vector data" export format when exporting maps. For complex layers that should only be visible in large scale ranges, we recommend that you select the export format "Grid data".

What media formats does Cadenza Mobile support?

Cadenza Mobile supports the following media file formats, provided that the mobile device's operating system supports them:

  •  Image formats: .png, .jpg, .jpeg, .gif, .tif, .tiff, .bmp
  • Video formats: .m4v, .mp4, .mov, .3gp, .wav, .ogg
  • Audio formats: .3gpp, .ac3, .mp3, .wav, .webm, .ogg
  • Additional formats: .xls, .doc, .ppt, .pdf, .odt

Which factors influence the duration of the export?

There are four factors that affect the time required for exporting the mobile map:

  1. Number of layers o Only export those layers that you actually need
    • Group layers that fit together and do not need to be shown or hidden individually on the mobile device (group layers).
    • Move layers that you use in multiple mobile maps to a separate mobile map. You can also show these layers in other mobile maps. For this purpose, use the app's map view and select the layer list.
  2. Maximum scale of the mobile map
    • Make sure to select the smallest possible value for the maximum scale.
  3. Number and size of the linked documents and media files
    • Linked media files and documents are also exported for each layer: Make sure that you choose a small file size when you add the respective files.
  4. Use of data sources that Cadenza Desktop can access reliably
    • Ideally, your map data is available locally on your computer, so that network access is avoided. If possible, use Solid State Disks (SSD) for your data storage and the local user directory.
    • Accessing services can significantly slow down the export process, since many services have a long response time.

How does the size of the mobile map affect the map application?

Only the number of layers contained in the mobile map affects the tablet's processing speed. The map extent and the size of the mobile map have no influence on this. Please note:

  • The larger the export file, the longer the export process takes.
  • You must expect that during the export process the map will occupy at least 2.5 times its size in temporary storage space on your computer. The same applies to the import of a map. So if the map is 0.5 GB in size, you will need at least 1.25 GB of free disk space.
  • Downloading the mobile map from the server to the tablet takes longer if you use large maps.

How many network data sources can I use?

For long map export processes, we recommend that you use as few network data sources as possible. They are generally less reliable, and the performance of local data sources is often higher.

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.
