This document describes how to build a mobile check-in app in 75 minutes using ArcGIS Online and various ArcGIS APIs. It outlines the key components and services needed, including geocoding, routing, feature services to find and update points of interest. The app allows users to find nearby pizza places, get driving directions, check in when arriving and leaving to share their experience. Building the app on ArcGIS Online provides a cloud-based geospatial solution that can be accessed from any device and monetized through advertising or additional business insights.

32. ArcGIS Online Basemaps
Visualizing your world

33. Base layer options…

34. Projections and Spatial References

35. Where in the world am I?
Mercator
Geographic - WGS 1984
-87.6,41.9
-9743828.3,5131825.1

36. Basemap Service
var basemapURL =
“http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer”;
dojo.require("esri.map");
map = new esri.Map("mapDiv", { wrapAround180: true, null });
map.SetSpatialReference({"wkid":102100});
var basemap = new
esri.layers.ArcGISTiledMapServiceLayer(basemapURL);
map.addLayer(basemap);

37. ArcGIS Online Services
Solving problems

38. Where am I?

39. Input Coordinates
navigator.geolocation.getCurrentPosition(zoomToLocation, this.geolocationError);
function zoomToLocation(location) {
var centerPoint = esri.geometry.geographicToWebMercator(
new esri.geometry.Point(location.coords.longitude,
location.coords.latitude));
var symbol = new esri.symbol.PictureMarkerSymbol(
{"url":”images/BluePin1LargeB.png“,”width":28,"height":28} );
var graphic = new esri.Graphic(centerPoint, symbol);
geolocationLayer.graphics.add(graphic);
map.centerAndZoom(centerPoint, 16);
}

40. Geocode Service
var geocodeService = new
esri.tasks.Locator("http://tasks.arcgis.com/ArcGIS/rest/services/WorldLocator/GeocodeServer");
var address = { "SingleLine": address };
locator.outSpatialReference = map.spatialReference;
var params = {address: address, outFields: ["Loc_name"]}
geocodeService.addressToLocations(params, geoCodeResults);
Ext.each(candidates, function (candidate) {
if (candidate.score > 80) {
var geom = candidate.location;
var graphic = new esri.Graphic(geom,
symbol, null);
geoCodeLayer.graphics.add(graphic);
}
});

41. Drive time tolerance?

42. Geoprocessing Service
var geoProcessService = new esri.tasks.Geoprocessor(
"http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Network/ESRI_DriveTime_US/GPServer/C
reateDriveTimePolygons");
var driveTimes = “1 2 3”; // minutes
var featureSet = new esri.tasks.FeatureSet();
featureSet.features = features.push(geoCodeGraphic);
var params = {"Location":featureSet,"Times":driveTimes };
geoProcessService.execute(params, driveTimeResults, null);
function driveTimeResults(results,messages) {
var features = results[0].value.features;
for (var f = 0, fl = features.length; f < fl; f++) {
var feature = features[f];
if (f == 0) // minute 1
feature.setSymbol(polySymbolRed);
if (f ==1) // minute 2
…
driveTimeLayer.add(feature);
} );
}

43. Find places of interest

44. Feature Service – “geo query”
var poiCloudFeatureService = new QueryTask
("http://services.arcgis.com/uCXeTVveQzP4IIcx/arcgis/rest/services/BIG_POI/FeatureServer/0");
var q = new esri.tasks.Query();
q.returnGeometry = true;
q.outFields = ["NAME", "ADDRESS", "PHONE", "DESCRIPTION"];
q.geometry = driveTimeGeometry;
q.spatialRelationship = esriSpatialRelIntersects
q.where = "Cuisine = 'pizza'";
poiCloudFeatureService.execute(q, addPizzaLocations, null);
function addPizzaLocations(features) {
Ext.each(features , function(feature){
graphic = new esri.Graphic(feature.geometry,
symbol, null);
pizzaLayer.add(graphic);
});
}

45. Select a place

46. Graphics Query
var pizzaLayer= map.layers["pizzaLayer"]; // stay local
dojo.connect(pizzaLayer, "onClick", displayInfo);
function displayInfo(args) {
var pizzaLocation = args.graphic;
var newView = Ext.create('PF.view.PizzaLocation',
{
fullscreen:true,
feature:pizzaLocation,
title:pizzaLocation.attributes['Name']
});
this.defaultMapView.push(newView);
}

47. Ok, take me there!

48. Route Service
var routeService = new esri.tasks.RouteTask
("http://tasks.arcgisonline.com/arcgis/rest/services/Network/USA/NAServer/Route");
var params = new esri.tasks.RouteParameters();
params.stops.features[0] = startLoc;
params.stops.features[1] = endLoc;
params.returnDirections = true;
params.directionsLengthUnits = esri.Units.MILES;
routeService.solve(params, function (solveResult) {
var directions = solveResult.routeResults[0].directions;
directionFeatures = directions.features;
var routeGeom = directions.mergedGeometry;
var startPt = routeGeom.getPoint(0,0);
var lastPath = routeGeom.paths[routeGeom.paths.length - 1];
var endPt = routeGeom.getPoint(routeGeom.paths.length – 1,
lastPath.length - 1);
}
function addGraphics(startPt, endPt, lastPath)…

49. Are we there yet?

50. Geometry Service - geofencing
Var geomService = new esri.tasks.GeometryService(
"http://tasks.arcgisonline.com /ArcGIS/rest/services/Geometry/GeometryServer");
var bufParams = new esri.tasks.BufferParameters();
bufParams.distances = [ 25 ];
bufParams.geometries = [ toPt ];
bufParams.outSpatialReference = new
esri.SpatialReference({"wkid":102100});
geomService.buffer(bufParams,
function (geometries) {
var geoFence = geometries[0];
var symbol = self.checkinToleranceSymbol;
var graphic = new esri.Graphic(geoFence, symbol);
geoFenceGraphicLayer.add(graphic) });
…
isPoint InFence = geoFence.contains(currentLocation); // local

51. check-in

52. Feature Service – update the cloud
var checkInLayer = new FeatureLayer(
"http://services.arcgis.com/uCXeTVveQzP4IIcx/arcgis/rest/services/PizzaCheckins/FeatureServer/1");
// Invisible layers
var distance = getDistance(routeGraphic);
var duration = getDuration(checkInTime, checkOutTime);
var userRating = getUserRating(duration, distance);
routeGraphic.Attributes["POI_ID"] = poi.attribues[' POI_ID' ];
routeGraphic.Attributes["Name"] = poi.attributes[' NAME' ];
routeGraphic.Attributes["CheckIn"] = checkInTime;
routeGraphic.Attributes["CheckOut"] = checkOutTime;
routeGraphic.Attributes["Duration"] = duration;
routeGraphic.Attributes["Distance"] = distance;
routeGraphic.Attributes["Rating"] = userRating;
checkInLayer.applyEdits([routeGraphic], null, null);
