Use Phone GPS to find closest store

[NickK]

Hello, 

I've built an app to give colleages in the field easy access to retail store level data (sales, lease & design info). 

They are asking for me to add the ability for the app to find the nearest store to them instead of searching for a store. 

I know I can use the phone's gps location and all my records have latitude and longitude coordinates (in decimal degrees) as well. 

Has anyone attempted this?

I've found several examples of the math required to get the distance between 2 sets of Lat&Long values, but they require setting variables for a distance calculation. (Something I haven't done). 

Any help will be appreciated, Thanks!

Hi,

I think of three ways you can solve your issue:

1 - If you have the function, you can create hidden text labels as intermediate values; You can do some math by just pointing the Label name (e.g., Label1/2 will get Label1 value and divide by 2)

or

2 - You can try using Context variables (e.g., UpdateContext({val1:Location.Latitude});UpdateContext({var:Atan(val1/2)}) for a dumb example);

3 - You can create a customapi that can connect to some api (such as Bing maps) and makes the math directly. This option needs more work to build, but it's better since it will get you the actual driving distance between two points and might eventually give you the traffic, etc.

There might be better solutions, though.
