Objectives

GEO DATA GEODATA SCIENCE (GDS) GEO-TAGGED VISUAL MEDIA VOLUNTEERED GEOGRAPHIC INFORMATION BLOCKCHAIN WITH GEO TAGS IMAGE BLOCKCHAIN APPLICATIONS USING GEO DATA .

Geo-Data

• Data and information having an

implicit or explicit association with a location relative to Earth .

It is also called :

• geospatial data and information
• georeferenced data and information
• geodata and geoinformation

Geodata science (GDS)

• Is the science to studying and mining

the geospatial data to derived meaningful and unknown geoinformation and knowledge , and making spatial decisions.

Geodata science (GDS)

• Benefits :

1. well understand the origin, evolution and future of our Earth and planet 2. prediction and assessment of earth resources, environments, and natural hazards. GDS methods for exploring and mining geoscience data including :

• 1. data statistics.
• 2. data mining.
• 3. data insight and prediction.

Geodata science (GDS)

• The paper [1] is a case study on geochemical

exploration data mapping.

• The results shows that GDS is a new research

paradigms for exploring the spatial association of geochemical patterns .

• They used statistical analysis (standard and mean) in

their study .

Geo-tagged visual media

• Geo-tagged visual media is a form of volunteered

Geographic information (VGI)

• Volunteered Geographic information (VGI) [2] :

enable a crowdsourcing process to create information-driven

• value. VGIS, implemented by executing a project and its

crowdsourcing strategy, are driven by online networked community participation enabled by a technological infrastructure.

• In the geo-spatial domain, organizations are taking

advantage of technological improvements on the demand side of geographic and location-based data and services, to involve volunteers on the Web to take part in the production of (VGI)

Volunteered Geographic information

Examples : 1. The International Institute for Applied Systems Analysis (IIASA) has created Geo-Wiki, an information portal that allows volunteers to improve data on land cover using satellite imagery from Google Earth. 2- Flicker website and application 3- Columbus App : is a mobile application that lets users explore their surrounding through geotagged photographs.[4]

Land cover classification

• [3] present and evaluate a framework to filter relevant geo-

tagged image from social network sites for Land cover classification tasks .

• This framework used computer vision to analysis the content of

geo tagged image on social network sites to generate descriptive tags .

• These photos are used to train Artificial Neural Network to

predict photos relevance for land cover classification .

• The framework implemented with Geo-wiki to fetch relevant

photos from flicker .

La Land Cover Cla lassification

• The main outcome of the study is reusable framework to find & filter

imagery that can help determine land covers types and investigate weather particular countries should have customized model or weather data from all countries can be used to build one generalized model .

• The model have been able to classify the images into classes like

(outside ,outdoor, sand , containing trees and others)

• The outcome is integrated to Geo-wiki

Geo tagged image with blockchain

• Geo market place allow owners to advertise

their data to interested buyers .

• They propose geo-market place with three

key-feature : 1. Privacy : using searchable Encryption Technique es to protect location . 2. Accountability 3. Spam resilience

Ge Geo tagg agged im image with ith blo lockchain in

• Techniques that have been used:

1. Searchable Symmetric Encryption 2. Hidden Vector Encryption 3. Vector digital commitment 4. Blockchain ,smart contacts , bulk storage .

Blo lockchain in in fin financial fie field : Bit itcoin and Ethereum

Bitcoin -2009 (digital money) is a developer app that uses Blockchain technology it is the first cryptocurrency use of blockchain technology It aims to fix the problems in global finance, often referred to as the “bank of the people”. Used for manual transactions, like purchasing goods/services

• r receiving money.

It takes minutes to complete Bitcoin transactions.

Blo lockchain in in fi financial fi field : : Bit itcoin and Ethereum

• Ethereum-2015 (smart contracts)
• It is another cryptocurrency app like Bitcoin .
• It is another use case for the blockchain that supports

Bitcoin and is the second widespread operation after Bitcoin, widely known synonym is “Blockchain 2.0”

• It provides a platform to build smart-contract apps

(known as dApps).

• It provides a programming language, called Solidity, to

build the dApps with

• The Ether ecosystem is much smaller than the Bitcoin

system since the market value of ether in 2020 is just under $ 16 billion, while the price of bitcoin is almost 10 times what Over 147 billion dollars.

• Ethereum’s transactions take seconds to complete

Blo lockchain in in Land registration.

• The land registration system : It is a

system that uses a decentralized database that enables some companies Selling their property in a virtual environment. Land registration procedures are implemented through a blockchain It reduces intermediaries (the third party), as this method is considered safe and transparent for carrying out many transactions.

Blockchain in in Food tr tracking systems

• Work on this system began in October 2018, when IBM announced that

it could Track data of food supply chain and trade line from farm to store (IBM, 2018) .The system allows food retailers, whether suppliers or growers, to view supply chain data nearby In real time, the way to determine the origin and safety of products is easily and transparently.

Blockchain- based mobility management for 5G

• Blockchain use in mobile communications:

Blockchain technology supports Bitcoin to securely conduct financial transactions without intermediary such as banks.

• For example, 5G is expanding the field of mobile

communications outside LTE, helping to enable sensors and other devices to share data over the cellular network. It is possible that the large volume of data contributes to poor security in delivery.

• It makes the network vulnerable to attack as

well as slow response and slow, the use of blockchain helps us to overcome these problems.

Blockchain in Transportation

Supply chain management can be implemented in the transportation system, where stakeholders can track the goods Along the chain without relying on a central entity for branded product authenticity as well as RFID technology. it allows companies to track their products from the creation step to delivering them to the end consumer. and helps them improve their business and know the identification of problems in the chain to address.

Blo lockchain in in the genetic energy sector

• Blockchain plays a role in the genetic energy sector It

is a mathematical form that stores data in a safe and free from counterfeiting, as there is a lot of interest

• n the application of the blockchain in genetic

energy and research operations.

• Blockchain technology plays a big role in improving

the efficiency and sustainability of genetic energy in various ways. Also, with the development of technology, there are barriers that stand in the way

• f its spread.

Continue

• Some studies confirm that the use of Blockchain to

manage market transactions in Geothermal energy, electricity, or even renewable energy Oil and gas are very important and an innovative topic with the development of technology as research initiatives in the industry emerged to explore Innovative ways to present value using a blockchain such as Intel, where it was a founding member and also the Blockchain Association for Oil and Gas

Blo lockchains in in in industries

• Blockchain is used in the electricity

sector where interactions are facilitated from one device to another so that producers and consumers can interact with each

• ther effectively.
• Blockchain technologies are also

used in industries such as pharmaceutical and medical products that need strict and safe control by all parties.

Blockchain in in th the healthcare sector

• Patient and health data is usually exchanged between multiple

sources, such as doctors, patients or even insurance companies, as well as clinics, because ownership of this information is very important and safety breaches it are very dangerous so blockchain is used in this field as it reduces errors in information and records Patients and make transactions safer.
