Current poster presents an example of Landsat TM image processing using ENVI GIS. Research area: Taipei, Taiwan. Located on the north of the island, Taipei is Taiwan’s core urban, political and economic center; population >2.6 M continuing to expand affecting urban landscapes. Research aim: spatio- temporal analysis of urban dynamics in study area during 15 years (1990- 2005) Research objective: application of GIS methodology and remote sens- ing data to spatial analysis for a case study of Taipei. Data: Landsat TM images taken from the USGS. Software: ENVI GIS. Workflow includes following steps: 1) Preliminary processing 2) Creation color composites 3) Classification using K-means algorithm 4) Mapping using classification results 5) Accuracy assessment. The preliminary data processing includes image contrast stretching, which is useful as by default, ENVI displays images with a 2\% linear contrast stretch. For better contrast the histogram equalization contrast stretch was applied to the image in order to enhance the visual quality. The analysis of landscape changes was performed by geospatial analysis. 2 satellite images Landsat TM were processed and classified using ENVI GIS. Result of classification: areas occupied by different land cover types were calculated and analyzed. It has been detected that different parts of the city of Taipei were developing with different rate and intensity. 3 different residential types of the city were recognized and mapped. The results demonstrated following outcomes: 1) intensive urban development of the city of Taipei; 2) decline of green areas and natural spaces and, on the contrary, increase in anthropogenic urban spaces; 3) not parallel urban development in different districts of the city of Taipei during the 15-year period of 1990-2005.

This study determined using divergence measures the best indivi- dual and combinations of various numbers of bands for six land cover/use classes around the city of Arequipa, Peru. A 15 band data stack consisting of PALSAR L-band dual-polarised radar, Landsat optical data, as well as six variance texture measures extracted from the PALSAR images, was used in this study. Spectral signatures were obtained for each class for the diver- gence examination. The band having the highest separability was the Landsat visible red band followed by the two largest window PALSAR texture measures. The best three band combina- tion included three very different data types, Landsat visible red, near infrared and the PALSAR HH variance texture from a 17 × 17 pixel window. There was no need based upon the diver- gence values to use more than five bands for classification.

The need for the production of Topographic Information System (TIS) of Federal School of Surveying, Oyo arose due to the absence of Topographic Information System for proper planning of the school. Therefore, TIS was carried out with the aim of producing a tool for effective planning and land management of the school. Field and Office reconnaissance were carried out in order to be familiar with the terrain and do proper planning on the methodology and equipment to be used for the acquisition and assembling of spatial and attribute data. The geometric (spatial) data were acquired by ground survey method using Total station (South S74301) through the process of traversing, detailing and obtaining spot heights which were carried out simultaneously. The data processing were adequately and effectively done using Leica Geo Office Tools and South NTS Software for Data downloading, Notepad and Microsoft Excel for editing and preprocessing, AutoCAD 2016 for draughting, Surfer 11 for generating the Digital Terrain Model (DTM) and 3D Wireframe Map while ArcGIS 10.0 version was used for spatial analysis, query generation and information presentation. A model database was created and structured using the relational table format. The interpretation of the maps and queries produced, supports decision making policy needed by the Land surveyors, Architects, Engineers, Urban and Regional planners to plan, design and execute vital infrastructural projects in the school. It was recommended that TIS should become a lasting tool for decision making and management of land and its resources for effective and sustainable development.
An evaluation of Radarsat-2 individual and combined image dates for land use/...rsmahabir
Various land use/cover types exhibit seasonal characteristics which can be captured in remotely sensed imagery. This study examined how different seasons of Radarsat-2 data influence land use/cover classification accuracies for two study sites. Two dates of Radarsat-2 C-band quad-polarized images were obtained for Washington, D.C., USA and Wad Madani, Sudan. Spectral signatures were extracted and used with a maximum likelihood decision rule for classification and thematic accuracies were then determined. Both despeckled radar and derived texture measures were examined. Thematic accuracies for the two despeckled image dates were similar with a difference of 3% for Washington and 6% for Sudan. Merging the despeckled images for both seasons increased overall accuracy by 2% for Washington and 9% for Sudan. Further combining the original radar for both seasons with derived texture measures increased overall accuracies by 9% for Washington and 16% for Sudan for final overall accuracy values of 73% and 82%.

Remote sensing and geographic information systems (GIS) analysis involves the use of technology to gather, manipulate, and analyze spatial data to understand a range of phenomena. Remote sensing entails obtaining information about the Earth's surface by examining data acquired by a device, which is at a distance from the surface, most often satellites orbiting the earth and airplanes. GIS are computer-based systems that are used to capture, store, analyze, and display geographic information. These two approaches are used widely, often together, to assess natural resources and monitor environmental changes. Social scientists can gain insights into fine spatial and temporal dynamics of a range of social phenomena in environmental contexts by analyzing time series of remote sensing data, by linking remote sensing to socioeconomic data using GIS, and developing with these data a range of digital models and analyses. This article examines remote sensing and GIS in general, with an emphasis on the former, and then explores how these approaches may be used together to address a range of issues. It also emphasizes the role of remote sensing and GIS for use by scientists, engineers & geologists in water resources management

Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.

2. Geospatial analysis and its aspects, features and techniques in
geospatial technologies
Introduction
Despite in geographic information systems, most spatial analysis methods emerged before and
independently from GIS technology. Most of these methods have been integrated later into the GIS
technology. GIS platforms provide several functions such as data acquisition, data management and
visualization. The combination of these functions with analytical operations makes them even more
efficient.
The term ‘GIS’ is widely attributed to Roger Tomlinson and colleagues, who used it in 1963 to describe
their activities in building a digital natural resource inventory system for Canada (Tomlinson 1967, 1970).
The history of the field has been charted in an edited volume by Foresman (1998) containing contributions
by many of its early protagonists. The research makes the unassailable point that the success of GIS as an
area of activity has been driven by the success of its applications in solving real world problems.
Geospatial Analysis
Geospatial analysis in environmental science refers to the use of geographic data to identify
environmentally relevant information that is referenced to geography and that can also be referenced to
time. Four examples are the detection of environmental hazards, monitoring the spread of pollution over
time, analysis of trends in environmental parameters such as temperature and ocean acidity over time, and
to associate various environmental parameters with locations (such as droughts with geographical
location).
Geospatial analysis or modeling of spatial data has traditionally been the domain of geographic
information systems (GIS) specialists, employing commercial software and data products. Recent years,
however, have seen the development of open source tools and free or low cost web services, such as
Google Maps, that make geospatial analysis accessible and feasible to the non-specialist citizen scientist.
Geospatial analysis tools that can be applied to a range of questions relevant to stroke services. The codes
used here are for two free and open source software environments—R and Python.
Geospatial analysis tools allow manipulation and modeling of geospatial data. These tools, data, and
modeling techniques have a long track record in the quantitative geography, city and regional planning,
and civil engineering research literatures. Geospatial data, in the context of stroke research, includes the
location of patients and treatment centers, routes through the road network linking patients to treatment
centers, geographic and administrative region boundaries (e.g., post codes, government areas, and national
boundaries) and disease incidence and demographic information associated with such regions(Milne
MSW,2017)
3. Concept of Geospatial Analysis
In geospatial analysis, the location of a data point on the Earth's surface is referred to in terms of longitude
and latitude. In practice, longitude is the X axis and latitude is the Y axis. More complex data, such as
national boundaries or administrative or postcode boundaries consist of sets of points connected together in
defined orders, typically to produce a closed shape. Other structures, such as road networks, are also
constructed using sets of points and include other types of information, such as speed limits, travel
direction etc.
A geospatial framework provides mechanisms for representing, loading, and saving geospatial data and
performing fundamental mathematical operations (Pebesma E.,2018).For example, the simple features
package, on which some examples is based, provides structures to represent all manner of shapes and
associate them with non-spatial quantities, perform transforms between coordinate systems, display shapes,
compute geometric quantities like areas and distances and perform operations like intersections and unions.
A key emerging subdomain of geospatial analysis is spatial network analysis. Several open-source
packages now exist for modeling and analyzing spatial networks, such as urban street networks, including
dodgr for R (Padgham M. dodgr 2019) and OSMnx for Python (Boeing G. OSMnx,2017).
Aspects of Geospatial data or spatial data:
Spatial data, also known as geospatial data, refers to explain any data related to or containing
information about a specific location on the Earth's surface. According to the Bailey: "One difficulty
experienced in any discussion of links between GIS and spatial data analysis is clarification of exactly
what is to be considered as spatial analysis. The problem arises because, by its nature, GIS is a
multidisciplinary field and each discipline has developed a terminology and methodology for spatial data
analysis which reflects the particular interests of that field. In the face of such a diversity of analytical
perspectives, it is difficult to define spatial analysis any more specifically than as: a general ability to
manipulate spatial data into different forms and extract additional meaning as a result" (Bailey 1994, p.
15).

... Much geospatial data is of general interest to a wide range of users. For example, roads, localities, water
bodies, and public amenities are useful as reference information for a number of purposes.
Another example: First, I show to record the location of each tree in a well-defined study area. Then map
the location of each tree (a GIS task). At this point, I might be inclined to make inferences about the
observed pattern. Are the trees clustered or dispersed? Is the tree density constant across the study area?
Could soil type or slope have led to the observed pattern? Those are questions that are addressed in spatial
analysis using quantitative and statistical techniques.

Geospatial technology
5. Geospatial technologies is a term used to describe the range of modern tools contributing to the geographic
mapping and analysis of the Earth and human societies.
The science and art of photographic interpretation and map making was accelerated during the Second
World War and during the Cold War it took on new dimensions with the advent of satellites and
computers.
Techniques of geospatial technology:
Geographers employ a number of different techniques for collecting, studying, and analyzing spatial data.
These techniques include both quantitative and qualitative approaches, while also stressing important
computer-centered technologies. Many students trained in these techniques go on to work in a number of
different public and private industries, from planning departments to environmental assessment agencies to
non-profit community based organizations.
There are some techniques given below:
1. Global Positioning System (GPS):
A satellite-based geo-location system that functions worldwide and is accessible to the public via GPS
units a network of U.S. Department of Defense satellites which can give precise coordinate locations to
civilian and military users with proper receiving equipment.
Useful of GPS
-Records a location point associated with all observations
-Helps with data management
Triangulation
6. 2. Remote Sensing:
Imagery and data collected from space- or airborne camera and sensor platforms. ®
Images and data collected remotely.
® Often by satellite, but other platforms also exist.
® Information stored digitally, transmitted electronically.
® Often includes information invisible to human eye.
® Fully geo-referenced.
^ High Resolution Images -Best for observing
“human scale” phenomena -Highly targeted -
Narrow field of view ^ Low resolution images -
Best for regional phenomena
Multispectral
-Images in color
- Able to discern material types
- Post-processing often required
panchromatic
-Black and white
7. -Collect systematically
expensive
- wider field, more coverage, less
Panchromatic
3. Geographic Information Systems (GIS):
A suite of software tools for mapping and analyzing data which is geo-referenced (assigned a specific
location on the surface of the Earth, otherwise known as geospatial data). GIS can be used to detect
geographic patterns in other data, such as disease clusters resulting from toxins, suboptimal water access
etc.
Geographic Information System (GIS) is a data base management system which effectively stores,
retrieves, manipulates analyses and displays spatial information of both cartographic and thematic origin.
GIS is a computer based system which can handle large volumes of spatial data derived from a variety of
sources such as field surveys, aerial surveys and space remote sensing, in addition to the already existing
maps and reports. Access, etc.
4. Satellites:
A satellite is something that goes around and around the earth or another planet. Some satellites are
natural, like the moon, which is a natural satellite of the earth. Other satellites are made by scientists and
technologists to go around the earth. The Landsat’s (for land -sensing satellites) have for decades been the
most important remote-sensing satellites, though many others also have been launched. The first Landsat
was lifted by the United States in 1972 and the seventh was functioning as of 2002. Landsat’s circle Earth
at a low altitude of 420 to 912 kilometers (260 to 570 miles), passing over the North and South Poles rather
than circling the equator. This path means that Earth rotates inside the circular orbit of each satellite,
constantly presenting new territory to the satellite's view. The data collected by the Landsat’s are made
9. It works by radiating energy into space and monitoring the echo or reflected signal from the objects.
Radar studies of water and ice are not limited to Earth. The U.S. National Aeronautics and Space
Administration (NASA) has proposed that spacecraft mounted radar be used to peer through the icy crust
that covers Europa, one of the moons of Jupiter, to see whether a global ocean lies hidden beneath it. The
European Space Agency's Mars Express mission, scheduled for launch in 2003, was expected to carry
radar to map ice deposits in the soils of Mars.
6. Internet Mapping Technologies: software programs like Google Earth and web features like
Microsoft Virtual Earth are changing the way geospatial data is viewed and shared. The developments in
user interface are also making such technologies available to a wider audience whereas traditional GIS has
been reserved for specialists and those who invest time in learning complex software programs
