Missing telemetry tracking points on Map tile

Hello,

We're using the Azure IoT Central solution as some kind of proof of concept. We're passing coordinates from our devices and we want to display tracking in IoT Central based on last reported positions.

I see in IoT Central Raw data all my data with location points: 25 points, but when I use them in Google maps (as converted gpx) it shows me completely different shape of data/route than I see in IoT Central map tile. The map tile in IoT Central shows one point per 15 minutes (at least it looks like that), is it true? Is there any way to display all points on map tile, to see better route? We want to track our devices, see below images, the difference is huge.


This is the dataset (retrieved from IoT Central from raw data). The yellow points are visible on my map:

This is the Google Maps view based on exported data from that Excel (converted to gpx):

This is the Map tile in IoT Central (it shows 2 routes, but both routes should be the same, and they should match with Google Maps view):

The expected result in IoT Central is to see pretty much the same shape/route as it is in Google Maps, we're using in both places the same source data, so why they are different? Is there any limitations? Do you show only one point per 15 mins (based on my Excel sheet observations)? Can we do some operations/configuration to make it better? Our customers are not happy when they compare Google Maps with IoT Central.

Hello @sebsko-0421
We are checking on the below ask.

The map tile in IoT Central shows one point per 15 minutes (at least it looks like that), is it true?

Hello,

Ohh I see now, but there are more points between these displayed, so 100 points for me means last 100 points, so the beginning of the route should be skipped? Look these yellow points are/were visible, but white points not, so I expect last 100 points, or you take 100 points (avg) in selected time frame e.g. past week?

Hi there, Can you tell me what the Map Tile Time Range is set to? The larger the time range, the more sampling occurs across the location data points.

Hello,

I was trying to use different time ranges and smaller time range = more points and more frequent interval between them. I was checking 'past 1 hour', but ideally would be 'Past 1 day' or even week...

Hello @sebsko-0421

We have a response our product team and your feedback is considered in this scenario.

we split the selected time range into buckets and take a data point from each of those buckets. Hence, the larger the time frame, the larger the interval between points.
