Comparison of world map with europe city map

[YellowFoxNP]

Hi Bernd,

what are the differences between the Europe City map (Here) and the World Map (Here) in terms of

• performance
• system requirements
• and coverage?

For example, are the truck attributes for Germany the same in the Europe and World map?

Best regards

Hi Nico,

Thanks for this trigger! I will forward this thread tom some experts in the different domains (data/coverage, modules, system administration...) and request their feedback.

My personal expectation is:

• The HERE World map is a superposition of the continental HERE maps. Therefore the TruckAttributes in both maps should be equal in European countries compared to the World aequivalent.
• No direct impact on xCluster2, xTour2, xLoad2 as these modules do not access the map data by themselves. So I'd say we need to check this in xRoute2, xDima2, xData2, xLocate2.
• We offer some abbreviation mechanisms to refer to sub-units of the world map. I recommend that you check this article about country codes. It explains how to apply codes such as "zz-eur" to restrict a routings search space to European countries. We also use the abbreviations for the search graphs in the HPR context.
• There's also a com.ptvgroup.xserver.xlocate.SearchOptions parameter in xLocate 2 that speeds up the indexed search in a significant manner (unfortunately does not support the abbreviations mentioned above).
• Of course you will need more disk space and memory.

Here are also some related forum posts:

• Data quality comparison of providers
• How to evaluate coverage of traffic data via PTV APIs (also applies to otherfeature layers such as PTV_TruckAttributes)

Here's some feedback from Nazir:

We do not use continent specific map, we use World Map for all xServer2 environments, so on Cloud and on Datacenter environments.

If the customer runs xServer application on a local environment, having a plane map folder locally would be the best way for them. Because, it's easier to patch and faster to process. We can create a guide for installation.

System requirements depend on usage, however for running a World Map on a Linux machine we recommend

• At least same amount of cores as modules ( if there are 8 modules overall, then at least 8 available cores)
• At least 60GB of RAM for World Map (Our least used environment has 100GB RAM)
• Faster SSD storage for World Map (at least 250 GB)

On the other hand, I cannot give you an exact comparison of maps. But, we can try both - World and Continent map in the same environment with the same requests to find out the performance difference.

I hope the information above helps you a bit. Please, do not hesitate to ask more questions if you have any.
