Bing maps: Calculate distance between 2 waypoints (straight line)

[UI1222]

Hi 

I was inspired by Reza Dorrani video on geospatial components on youtube: https://youtu.be/cj2cC8EBj-I 

So far everything is working perfectly. 

The calculation above is the distance following roads, and estimated traveltime with current traffic. 

I would like to add a calculation with the distance between the 2 waypoint in a straight line, does anyone know how to do that?  

Just like this website, with the same waypoints:

Hi @UI1222

The way I would approach this would be to call a Flow, or to create a custom connector that calls the Bing REST API.

I'm tagging Reza so that he can better advise.

@timl 

Thank you for the input. 

Does the Bing API supports this? or is it under development, like some of the other things @RezaDorrani mentioned in the video.

The latitude and longitude are in the data set. I guess its possible to calculate it using math, in some way, but im not sure how.

Hi @UI1222 ,

Do you want to  calculate the distance between 2 waypoints (straight line)?

Regarding the needs that you mentioned, I think the GetRoute action under Bing Map connector could achieve your needs. I have made a test on my side, please try the following workaround:

Set the Text property of the Label to following:

BingMaps.GetRoute(TextInput1.Text, TextInput2.Text, {optimize:"distance",distanceUnit:"Kilometer"}).travelDistance

Note: More details about GetRoute action under the Bing Map connector, please check the following article:

https://docs.microsoft.com/en-us/connectors/bingmaps/#get-route

Of course, if could also consider calculate the Distance between two different Way Points using Math function. Please check and see if the following thread solution could help in your scenario:

Please try above solution, then check if the issue is solved.

Thank you for the input. 

Yes, I want to calculate the distance between 2 waypoints in a straight line. 

A long story short. We have to pay our employees according to some rules made 100 years ago. Before route calculations where available. Back then, you drew circles on a map around your Company, the further the employee had to travel away from the company to a building site, the more you had to pay.  

I'm already using the GetRoute formula in my calculation in the first picture. It works great. But its not what I need in this situation.

Note: The distance actually vary a lot between the two calculations. 33 vs 18 km.

Hi @UI1222 ,

Have you tried the Math Calculation solution I provided above?

I've tried the formula, but I cant get it to work.

Finally made it work. Thanks to PowerAppster on Youtube: https://youtu.be/h-ZSd4w926k

Here is how my version works. (Note: my syntax is danish, so you might need to replace ; with ,)

Set pi as a global variable:

Set(varPI;0,017453292519943295) 

Set Waypoint 1 and Waypoint 2 as Global variables:

Set(varWP1;BingMaps.GetLocationByAddress({addressLine: YourSource.Address; locality: YourSource.City; postalCode: YourSource.PostalCode}));;

Set(varWP2;BingMaps.GetLocationByAddress({addressLine: YourSource.Address; locality: YourSource.City; postalCode: YourSource.PostalCode}))

Im my case, Waypoint 1 is always one of out company adresses, and Waypoint 2 is always a local building site. 

Set this formula in a variable or just on a label:

Round(12742 * Asin(Sqrt(0,5 - Cos((varWP1.point.coordinates.latitude - varWP2.point.coordinates.latitude) * varPI)/2 + Cos(varWP2.point.coordinates.latitude * varPI) * Cos(varWP1.point.coordinates.latitude * varPI) * (1 - Cos((varWP1.point.coordinates.longitude - varWP2.point.coordinates.longitude) * varPI)) / 2));2)

The output is the distance between the 2 waypoints.

Hi, I've been trying to duplicate this; I have kind of really similar issue with my work, but here the issue is no the routes but the lack of a directions system in the country AND I need to check if my coworkers are at our customer's locations as needed.

Currentlý I have this:

Waypoints:

Set(varWP1,BingMaps.GetLocationByPoint(Value(lb_Loc_Lat.Text),Value(lb_Loc_Lon.Text)));
Set(varWP2,BingMaps.GetLocationByPoint(Value(lb_Sup_Lat.Text),Value(lb_Sup_Lon.Text)))
Note: lb_Sup_Lat/Lon and lob_Loc_Lat/Lon has the coordinates as Decimal Degrees (DD); May this be the issue? But the location of my coworker is Location.Latitude/Longitude so I believe it shouldn't be...

Label of Distances:
Round(12742 * Asin(Sqrt(0.5 - Cos((varWP1.point.coordinates.latitude - varWP2.point.coordinates.latitude) * varPI)/2 + Cos(varWP2.point.coordinates.latitude * varPI) * Cos(varWP1.point.coordinates.latitude * varPI) * (1 - Cos((varWP1.point.coordinates.longitude - varWP2.point.coordinates.longitude) * varPI)) / 2)) , 2)

Note: Just replaced the parts highlighted as Bold) and result still "0"

Hi UI1222, thanks for sharing this. Unfortunately I'm getting an error - I think it's because 2 parameters are being used for the Sqrt function? Looks like a 0 is being provided followed by a formula? I took the 0 out but I'm still not getting the correct result 😞
