Android Geo Apps: In Soviet Russia latitude and longitude find you

About

● I am a scientist. The area of my interests includes machine learning, traffic jams prediction, BigData algorythms.

● But I'm a programmer, so I'm interested in NoSQL databases, Java, Android, Hadoop, Spark.

● I am a fan of variety GEO API (Maps API for example)

Introduction

Some maps are extremely old

Some maps are inaccurate

Some maps are used in games

And, of course, some maps are realistic

● Geo applications are a specific

type

● Maps are optional

● Geo content in your app

● There’s a mobile aspect

Geo apps

Revenue

Localizing Content

Managing Digital Rights

● Popular commercial sites pay for

usage

● Limits

● Google Maps for business

● AdMob integration

● Time in app

Google’s profit

● Media content with geolabel

● Places, addresses, organizations

● Wiki

● Type of activity

● Individual tracking

● Purchases

Data

Targeting Advertising

Data sources

● Cell of Origin : finds location by

CellID

● Time of Arrival (TOA)

● Observed Time Difference (OTD)

● A-GPS : starts from base stations

LBS (Location Based Services)

● GPS guzzles battery power

● GPS is often inaccurate

● People active in more than 10

times

Why LBS?

Geo Technologies

● Latitude & longitude

● Latitude is y, longitude is x

● But it looks like this: (y, x)

● To indicate the cities, regions and

countries you need diffirent

coordinate precision

● Spherical geometry

Latitude and longitude

Mercator Projection

Maps

The Maps Family Let's map everything on the map

● Convenient controls (zoom)

● Geocoding

● Routing

● Layers

● Gestures

● Showing traffic jams and public

transport (optional)

Opportunities of Respectable API

● v2 with 3D rendering

● Gesture control

● Best support and documentation

● Heatmap & clustering

● Simple integration with location API

● Best demos

Google Maps

● Heatmaps

● Marker’s icon customizing

● Clusterization

● Customizing of marker clusters

● Calculating distances and areas

(spherical geomatry)

Android API Utility Library

● Template project in Android Studio

● Obtaining API key in Google Developer Console

● Changing Manifest and Gradle build script

● Playing with examples

● Debugging on the real device

● Updating GooglePlay services on the virtual devices

How to attach Google Maps?

● This SDK was designed to work with

Android 2.x devices

● Best photos from space

● Excellent coverage in the U.S.

● Supports geocoding, reverse

geocoding, and routing

Bing Maps SDK

● Excellent coverage in Russia

● More attractive on iOS

● No direct geocoding

● Development was stopped

● No special limits

● 25,000 geocoding requests per day

Yandex Map Kit

● Data from OpenStreetMaps

● Best coverage in the world

● Development by community

● No routing & traffic jams

● Tiles from MapQuest + OpenLayers

● Fork & control code :)

● Offline maps via MobileAtlasCreator

OsmDroid

● Add osmdroid libraries to CLASSPATH

● Include slf4j-android logging library

● Add a MapView to your xml layout

● Add permissions to manifest

● If it is required, create a tile provider chain

● If it doesn’t work, copy simple example

How to build OSM app?

● Modern JS API and ancient Android

API (waiting new Android SDK)

● Geocoding, routing, traffic plugins for

Leaflet (JS Library)

● Simple features without key and

advanced features by API key

MapQuest

● OsmDroid fork

● Free for 50k views in month

● GeoJSON and TileJSON support added

● Data objects like points and lines use doubles instead of the

E6 int convention

● Small separate modules for different tasks

● See github

MapBox

●

● PostrgreSQL/PostGIS

● osm2pgsql

● Mapnik (rendering of OSM data)

● Ruby magic

● Grab OSM data (planet dump)

● Quick ref here

Waiting for signal ...

If you developing a project for...

● a U.S. company - Bing Maps● a transnational company - Google Maps● a Russian company, or one in in the former U.S.S.R. -

YandexMapKit● OpenSource with special tiles - MapQuest + OpenLayers● OpenSource with its own data - OsmDroid● Tuning OpenSource and paid API - MapBox● … just to play - NokiaMaps
