The document describes a project to create an interactive 3D model of Kathmandu University by integrating spatial data from multiple sources. A team of students used software like SketchUp, ArcGIS, and Google Earth to develop 3D models of buildings and terrain at KU from plans, cadastral data, and georeferenced images. These models were combined and georeferenced in ArcScene to produce a 3D representation of the university. The final 3D model was made interactive by adding functionality for zooming, panning, and changing views for web dissemination.
The Global Positioning System is a satellite-based radio navigation system for determination of precise position and time, using radio signals from the satellites, in real-time or in post-processing mode.
The advantage of digital imagery is that it allows us to manipulate the digital pixel values in the image. Even after the radiometric corrections image may still not be optimized for visual interpretation. An image 'enhancement' is basically anything that makes it easier or better to visually interpret. An enhancement is performed for a specific application as well. This enhancement may be inappropriate for another purpose, which would demand a different type of enhancement.
Filtering is used to enhance the appearance of an image. Spatial filters are designed to highlight or suppress specific features in an image based on their spatial frequency. ‘Rough’ textured areas of an image, where the changes in tone are abrupt, have high spatial frequencies, while ‘smooth’ areas with little variation have low spatial frequencies. A common filtering procedure involves moving a ‘matrix' of a few pixels in dimension (ie. 3x3, 5x5, etc.) over each pixel in the image, using mathematical calculation and replacing the central pixel with the new value.
A low-pass filter is designed to emphasize larger, homogeneous areas of similar tone and reduce the smaller detail in an image. Thus, low-pass filters generally serve to smooth the appearance of an image. In some cases, like 'low-pass filtering', the enhanced image can actually look worse than the original, but such an enhancement was likely performed to help the interpreter see low spatial frequency features among the usual high frequency clutter found in an image. High-pass filters do the opposite and serve to sharpen the appearance of fine detail in an image. Directional, or edge detection filters are designed to highlight linear features, such as roads or field boundaries. These filters can also be designed to enhance features which are oriented in specific directions.

LiDAR acronym as Light Detection and Ranging is remote sensing technology having several technical and socialite advantages. This technology is basically used to make high resolution digital map to provide the real time data. This data can be processed and used to extract the useful information. A typical LIDAR system consists of three main components, a GPS system to provide position information, an INS unit for attitude determination, and a LASER system to provide range (distance) information between the LASER firing point and the ground point. In addition to range data, modern LIDAR systems can capture intensity images over the mapped area. Therefore, LIDAR is being more extensively used in mapping and GIS applications.

Covenant University location navigation system (CU Naviloc) built on the Android
platform is a mobile based system which can be easily accessed from an android
mobile device across any location, downloadable on Google play store and
deployable anywhere in the world. In this study,Computer-aided design as well as
building Information modelling (CAD/BIM) system applications were introduced to
the simulation of Covenant University, a smart and compact campus whose edifice
elaborates the need for the development of a three dimensional (3D) virtual model of
locations as an advancement over the existing 2D model representation of maps on
the Google map and Google Earth platform. Therefore, this research work outlays the
development of three dimensional models (CU NAViLoc Model) for details of
information at Covenant University as well as the requirements for its development
and implementation for cooperate representation of the institution. A three
dimensional map of CU was packaged into a location navigation system and was
implemented using Unreal Engine, Trimble SketchUp and Revit to effect a user
friendly, smarter and multi-dimensional viewable user interface. CU Naviloc explore
the advantage of the rich benefits of building information models and geographic
information systems to build a free-roam navigator, based on a well-updated model of
Covenant University location map. The benefits of this system is not limited to 3D
capability, real time similarity, portability, no downtime on access, and progressive
scalability with zero or little loss of data. The usage of the CU Naviloc system
requires free download and installation of the app and internet presence.

Euro30 2019 - Benchmarking tree approaches on street dataFabion Kauker
By examining the use of algorithms to solve the Prize Collecting Steiner Tree (PCST) problem we consider the facets which determine effectiveness. Specifically, by measuring a number of solution approaches and comparing them based on metrics. In order to understand the solution approach we must asses why it is useful. Our goal is to determine the effectiveness of Mixed Integer Programming (MIP) and heuristic methods. Utilizing freely available street and address data a base graph representation is created and then computed on. Such that a tree connects every address utilizing the minimum total length of edges from the street network. This is the basis of many approaches used to solve infrastructure problems including telecommunications network design and costing. The analysis is conducted on methods developed by Hegde et al. 2015, Ljubić et al. 2006, and Teitz et al. 1963. We present a data processing architecture, as well as a concise set of results and a framework for assessing the facets and trade-offs for a given approach. In this case the heuristic approaches are proven to have advantages in the simplistic case but fail when more complex requirements are added. This is where the MIP approach is able to capitalize, whilst detrimentally limiting the flexibility due to the strictness and specificity in modelling.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Kathmandu University being the leading institution of Nepal doesn’t have any
means to disseminate the University map portals among its visitors, students
and other stake holders
The two dimensional master plan without any spatial reference is still serving as
the tool to visualize the spatial position of the University components
So a necessity of three dimensional map was felt which could serve as a tool to
visualize all the features along with the terrain in digital form with the web
access.

TIN representation of the terrain
TINs are a form of vector-based digital geographic data and are
constructed by triangulating a set of vertices (points).
The vertices are connected with a series of edges to form a
network of triangles following Delaunay triangulation

INTERACTIVE TIN EDIITNG
The resulting triangulation satisfies the Delaunay triangle criterion
No vertex lies within the interior of any of the circumcircles of the
triangles in the network.
If the Delaunay criterion is satisfied everywhere on the TIN, the
minimum interior angle of all triangles is maximized.
The result is that long, thin triangles are avoided as much as possible.

Multisource data integration is often a complex task and involves the series
of coordinate transformation and file formats interpolability issues.
The users of today’s era wants map to be more interactive and user
friendly.
Accurate 3D modeling of the any geographical location first seeks the
quality data with completeness and correctness and also the excellent
working environment .
Establishment of the web server is the effective means of disseminating
the maps among the variety of users .
