create an application that can see location using arduino

To provide advice we need a better description of what you want and expect to do.

Here is a discussion linking an arduino with gps to App Inventor. It may be what you want.

Connecting ESP8266 (NodeMCU) with Android app (MIT APP inventor) especially the longitude and latitude from a gps module

This is the value of latitude and longitude in my serial Arduino. [gpswork] This is my example design in Mit App inventor [Screen1] This is the blocks of my design in Mit app [Screen2] Gps Code: #include <TinyGPS++.h> #include <SoftwareSerial.h> static const int RXPin = 3, TXPin = 4; static const uint32_t GPSBaud = 9600; // The TinyGPS++ object TinyGPSPlus gps; // The serial connection to the GPS device SoftwareSerial ss(RXPin, TXPin); void setup(){ Serial.begin(9600); ss.begin(G…

Here is a tutorial for using Map Markers. Part of it shows how to determine the nearest location to you. You might need some of that code.

National Park Tutorial (Markers) updated

A bubble sort creates a list of locations in ascending distance from the device. The first item in the calcul…

Is this what you need to know or something else?
