The document provides an overview of location services and positioning technologies. It discusses geolocation, which is estimating the real-world location of an object, as well as common global navigation satellite systems like GPS. Indoor positioning systems that locate objects inside buildings are also covered. The document then explores mapping technologies including geocoding, reverse geocoding, geofencing, and geovisualization. It concludes by discussing isolines on maps and the potential for an open location platform to connect disparate data sources using location as the link.

- * Location Services – The Past John Snow: Case Study Maps have been used to represent information throughout the ages, but what might be referenced as the first example of true location 'intelligence' was in London in 1854 when John Snow was able to debunk theories about the spread of cholera by overlaying a map of the area with the location of water pumps and was able to narrow the source to a single water pump. This layering of information over a map was able to identify relationships, and in turn insights that might otherwise never have been understood.
- * Location Services – The Present Exact percentage is controversial, but it is believed nearly 80% of all data is connected to location. https://www.gislounge.com/80-percent-data-is-geographic/ Of 30 topics studied in 2017, location intelligence was perceived as more critical than big data, social media analytics, or IoT.43% of respondents perceive location intelligence as very important20% of respondents perceive location intelligence as critically importantThus a total 63% of respondents highly weighed location services - Research & Development (R&D) and executive management are two functions that place the greatest importance on location intelligence analytics and business intelligence (BI). - Energy and transportation industries place the most significant emphasis on location intelligence analytics and BI today. - Marketing and sales have the highest level of interest in map-based visualizations of data and information. - Executive management is most interested in cloud-based deployments of location intelligence analytics, and BI gives cloud its highest criticality ranking. https://www.forbes.com/sites/louiscolumbus/2017/02/11/the-state-of-location-intelligence-analytics-bi-2017/#bb348b83ccba
- Location Services – The Future The future of an autonomous world requires location services. http://360.here.com/2015/04/16/autonomous-cars-can-understand-real-world-map/ A core data component of many Internet of Things (IoT) devices is location. IoT is forecasted to have up to 34 billion devices and 6 trillion dollars spent on IoT solutions by the year 2020. http://www.businessinsider.com/how-the-internet-of-things-market-will-grow-2014-10

- Core to location services is the ability to locate objects. This topic covers why positioning is relevant, different methods used for obtaining position, technical terms associated with positioning, and brief examples of technical implementations.
- In the simplest of terms, positioning is extracting the coordinates of an object
- DEFINITION: GEOLOCATION
- The way latitude and longitude work Positive (+) numbers for latitude are north, longitude are east. Negative (-) numbers for latitude are south, longitude are west.
- In the past, attempting to locate a geolocation was tough to do. Briefly touch on the basics of a sextant. http://www.wikihow.com/Use-a-Sextant
- DEFINITION: GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS) A common approach to obtaining a geolocation is to use a Global Navigation Satellite System (GNSS). An example of a GNSS implementation is the Global Positioning System (GPS) by USA, a global navigation satellite system that provides geolocation (latitude and longitude) and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Other example of GNSS implementations include: Galileo (Europe) 北斗卫星导航系统 (Beidou – China) ГЛОНАСС (GLONASS – Russia)
- Geolocation can also be obtained through resolving data points. For example, location data resolved from an IP address. http://whatismyipaddress.com/geolocation
- DEFINITION: INDOOR POSITIONING SYSTEM Indoor positioning system (IPS) is a system to locate objects or people inside a building using radio waves, magnetic fields, acoustic signals, or other sensory information collected by mobile devices.

- Online documentation on topics discussed thus far. OPTIONAL: Demo one or more of the topics covered
- Maybe a little history of cartography here. Humans have always made maps (cave paintings!). Important point to make: Making maps is HARD. Very few organizations make their own maps. HERE is one of them.
- Not all maps are alike. (In the screen captures above, bing map is shown on right, google map on left. The screen captures were relevant to attendees, so consider changing screen captures to location of venue where presentation is made)
- Even from the same map maker (HERE) we can see variations in maps. This is intentional when considering a political point of view. https://developer.here.com/documentation/map-image/topics/examples-map-pview.html

- DEFINITION: REVERSE GEOCODING (At this time, could also introduce concept of batch geocoding) (Consider changing example data to venue geolocation)
- Resource for learning more about developing with geocoding
- DEFINITION: GEOFENCING Discuss how commonly used to create a trigger of when an object enters/exits a geofence boundary
- Resource for learning more about how to develop for geofencing
