BasicGeopos 1.1.0

This is library for manipulating geolocation inside ClassLibs - UWP has BasicGeolocation, Android and MAUI has Location, but in .Net we have nothing.

constructor

new BasicGeo(latitude, longitude, altitude = 0) // args are validated since v1.1.0
Function Clone  // [since v1.1.0]
Function FromObject(anyObject as Object)    // tries to extract data from given object [since v1.1.0]

various distance metering

Function DistanceTo(dLatitude As Double, dLongitude As Double) As Double
Function DistanceTo(oGeoPos As BasicGeopos) As Double
Function DistanceKmTo(oGeoPos As BasicGeopos) As Double

Function IsNear(oGeoPos As BasicGeopos, distanceMeters As Double) As Boolean
Operator -(ByVal oGeoPos0 As BasicGeopos, ByVal oGeoPos1 As BasicGeopos) As Double

checking if BasicGeopos is inside various areas

Function IsLatitudeBetween(value0 As Double, value1 As Double) As Boolean
Function IsLongitudeBetween(value0 As Double, value1 As Double) As Boolean

Function IsInsideRectangle(latMin As Double, latMax As Double, lonMin As Double, lonMax As Double) As Boolean
Function IsInsideRectangle(oGeoPos0 As BasicGeopos, oGeoPos1 As BasicGeopos) As Boolean

Function IsInsideCircle(center As BasicGeopos, radius As Double) As Boolean

get centers of some regions

You can treat it as another form of constructors

GetEuropeCenter()   // "Mainland Europe"
GetEUCenter()       // "In Europe, not including overseas territories"
GetPolandCenter()
GetKrakowCenter()
Empty() // <=> (0,-150), middle of ocean; to make some scenarios easier

tests if we are inside one of these

These tests are done as IsInsideRectangle, not IsInsideCircle

Function IsInsideEurope() As Boolean
Function IsInsideEU() As Boolean
Function IsInsidePoland() As Boolean
Function IsInsideKrakow() As Boolean

Function IsEmpty() As Boolean   // test if current BasicGeopos is Empty one

serialization etc.

Helpers, to avoid warnings that ToString should have CultureInfo, etc. Default precision is 5 digits, it is about 10 meters.

Function StringLat(Optional iDigits As Integer = 5) As String
Function StringLon(Optional iDigits As Integer = 5) As String

Function FormatLink(sBaseLink As String) As String  // replace %lat , %long with values
Function ToOSMLink(Optional zoom As Integer = 16)
Function DumpAsJson() As String // dump as one-line JSON token [since v1.1.0]

DMS (degree, minute, second)

Function StringLatDM(Optional sFormat As String = "%d°%m′%s″", Optional iDigits As Integer = 5) As String
Function StringLonDM(Optional sFormat As String = "%d°%m′%s″", Optional iDigits As Integer = 5) As String

and constructors

FromDMS(latD As Integer, latM As Double, latS As Double, latSN As String, lonD As Integer, lonM As Double, lonS As Double, lonEW As String) 
FromDM(latD As Integer, latM As Double, latSW As String, lonD As Integer, lonM As Double, lonEW As String)
FromDM(latD As Double, latSW As String, lonD As Double, lonEW As String)
