- 2. Using Google Maps in Delphi apps • Introduction: Google Maps in Delphi apps • Architecture in a nutshell • Map options • Positioning, markers • Geocoding, reverse geocoding • Directions • GPX, GEOJson
- 3. Introduction: Google Maps in Delphi apps • Programmatic control of Google Maps via Delphi code • Wide range of geographical related functions • Available for - VCL apps for Windows - FMX apps for Windows, macOS, Android, iOS - IntraWeb apps for web • Easy to use Delphi classes, properties, methods. No Javascript required • Free liberal use of Google Maps, some use is paying https://console.developers.google.com/
- 4. Architecture in a nutshell WebBrowser control based • Navigate to https://maps.google.com • Injection of Javascript to interact with map via Google Maps Javascript API • Use WebBrowser interface to expose Javascript browser events as Delphi events • Additional use of Google geocoding / Reverse geocoding APIs
- 5. Map options • Map types: default, terrain, satellite, hybrid • Traffic • Streetview • Language • Controls: zoom, map type, streetview
- 6. Demo
- 7. Positioning • Map position: - WebGMaps.MapPanTo(), - WebGMaps.MapPanBy(X,Y) - WebGMaps.MapZoomTo(bounds) • Markers - WebGMaps.Markers.Add()
- 8. Demo
- 9. Geocoding, reversegeocoding • Translation of address to longitude & latitude and vice versa • Via TWebGMapsGeocoding, TWebGMapsReversegeocoding component • In VCL helper component: TWebGMapsLookupEdit
- 10. Demo
- 11. Directions • Calculating routes from point A to B • Optionally add waypoints • WebGMaps.RenderDirections() • WebGMaps.GetDirections() • WebGMaps.Directions result collection • WebGMaps.FillDirectionList()
- 12. Demo
- 13. GPX, GEOJson • Import and export GPX files WebGMaps.LoadGPSRoute(); WebGMaps.SavePathToGPSRoute(); • Import GEOJson files (http://geojson.org/) WebGMaps.LoadGeoJsonPolyLine(); WebGMaps.LoadGeoJsonPolygon();
