GEO DATA GEODATA SCIENCE (GDS) GEO-TAGGED VISUAL MEDIA Objectives VOLUNTEERED BLOCKCHAIN WITH GEO BLOCKCHAIN APPLICATIONS GEOGRAPHIC TAGS IMAGE USING GEO DATA . INFORMATION
• Data and information having an implicit or explicit association with a location relative to Earth . It is also called : Geo-Data - 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.
• The paper [1] is a case study on geochemical exploration data mapping. Geodata science • The results shows that GDS is a new research paradigms for exploring the spatial association of (GDS) 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 market place allow owners to advertise their data to interested buyers . • They propose geo-market place with three Geo tagged image key-feature : 1. Privacy : using searchable Encryption with blockchain 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 is a developer app that it is the first Bitcoin -2009 (digital uses Blockchain cryptocurrency use of money) technology blockchain technology It aims to fix the problems Used for manual It takes minutes to in global finance, often transactions, like complete Bitcoin referred to as the “ bank of purchasing goods/services transactions. the people ” . or receiving money.
• 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 Blo lockchain in in (known as dApps). • It provides a programming language, called Solidity, to financial fi fi field : : build the dApps with • The Ether ecosystem is much smaller than the Bitcoin Bit itcoin and system since the market value of ether in 2020 is just under $ 16 billion, while the price of bitcoin is almost 10 Ethereum 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 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 Blockchain- communications outside LTE, helping to enable based mobility sensors and other devices to share data over the cellular network. It is possible that the large management volume of data contributes to poor security in delivery. for 5G • 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.
• 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 on the application of the blockchain in genetic Blo lockchain in in the energy and research operations. • Blockchain technology plays a big role in improving genetic energy the efficiency and sustainability of genetic energy in various ways. Also, with the development of sector technology, there are barriers that stand in the way of 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 other 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.
