What Is Digitization In GIS: The Key To Effective and Efficient Mapping?

Digitization is the process of converting geographic data into digital form. During this process, spatial data on maps or images are traced as points, polylines or polygons. It has many uses in GIS, including recording and displaying geographic information, generating map layers, and storing data.

Digital datasets usually contain data that can be represented as numbers or symbols such as text or graphics. The process can also involve converting analogue images into digital ones.

GIS stands for Geographical Information System which is a software application that uses digitized data to model aspects of geography, such as earth surfaces, scientific fields, and social-cultural phenomena.

Digitization in GIS can be integrated with many other software applications like CAD (Computer-Aided Design), 3D modelling, etc.

Geographic Information System Definition – Robust & Complete Guide

 

Have you ever looked at a map and wondered how it was made? Well, one of the ways we create maps is by using something called a Geographic Information System, or GIS for short.

Geographic Information System, commonly known as GIS, is an innovative technology that has revolutionized the way we analyze and manage spatial data.

The Full Form of GIS is “Geographic Information System,” which is a powerful tool used for storing, analyzing, and manipulating geographical data.

GIS is a multi-disciplinary field that combines geography, cartography, statistics, computer science, and data management.

The Geographic Information System goes beyond just creating maps; it provides a platform for complex analysis of spatial data, creating models, and predicting future trends.

A Digital Georeferenced Reconstruction of al-Biruni's Map from The Masʿud Canon

Conference Paper

Full-text available

• Oct 2024

 

Abu Rayhan al-Biruni was a prominent Central Asian scientist from the Kingdom of Khwarazm. In the fifth volume of his 11-volume Al-Qānūn al-Masʿūdi (“The Masʿud Canon”) written in the first half of the 11th century AD and dedicated to Masʽud of Ghazni, al-Biruni provided the coordinates of 600 geographic objects of that time, such as cities, island...

 

Claudius Ptolemy's East Africa Georeferenced and Visualized

Article

Full-text available

• Dec 2023

 

In this paper, we present the product of the most recent continuation of our multiyear project that has involved georeferencing and visualization of data from Claudius Ptolemy’s classical ‘Geography’. The previously developed set of more than 2,200 translations of the ancient coordinates of Ptolemaic objects to the modern coordinates that can be vi...

 

 

Visualization and GIS Analysis of Ptolemy's One-Sided Globe in the Old and Modern Contexts

Article

Full-text available

• May 2022

 

In this paper, we frame the results of our multi-year project devoted to georeferencing and visualization of data from Claudius Ptolemy’s seminal ‘Geography’ in the context of other ancient, medieval and modern cartographic sources, some of which were influenced by or derived from Ptolemy’s massive and widely venerated classical work. Our GIS anal...

 

 

Enhanced Mathematical Method for Visualizing Ptolemy's Arabia

Article

• Sergey K. Stafeyev
• Mengjie Wang

In this article, we provide updates and enhancements to the mathematical methods for translating ancient coordinates from Ptolemy's classical Geography into coordinates that can be used in modern GIS tools, such as ArcGIS, QGIS, and Google Earth. We also expand our coverage from India to Arabia, another historically important peninsular subcontinen...

 

Iterative Reconstruction of Ptolemy's West Africa Using Modern GIS Analysis

Conference Paper

• May 2019

• Lyudmila M Filatova
• Dmitri Gusev
• Sergey K. Stafeyev

The multifaceted and challenging problem of reconstructing Claudius Ptolemy's map of ancient West Africa from the numeric coordinate data and other information found in his seminal 'Geography' and visualizing the results in modern projections using popular and powerful GIS tools, such as ArcGIS and Google Earth, is addressed by the authors iterativ...

 

 

Ptolemy's Britain and Ireland: A New Digital Reconstruction

Article

Full-text available

• May 2018

• Corey Abshire
• Anthony Durham
• Dmitri Gusev
• Sergey K. Stafeyev

In this paper, we expand application of our mathematical methods for translating ancient coordinates from the classical Geography by Claudius Ptolemy into modern coordinates from India and Arabia to Britain and Ireland, historically important islands on the periphery of the ancient Roman Empire. The methods include triangulation and flocking with s...

 

GIS Analysis and Digital Reconstruction of Ptolemy's India beyond the Ganges, Serike and Sinae

Conference Paper

Full-text available

• Apr 2018

 

In this paper, we use GIS analysis to produce a new digital reconstruction of the ancient India beyond the Ganges, Serike and Sinae, three peripheral regions from Claudius Ptol-emy’s classical Geography, a seminal work that provides coordinates of more than 6,300 places once known to the celebrated scientist of antiquity. We discuss practical impli...

 

 

The Fertile Crescent in Ptolemy’s “Geography”: a new digital reconstruction for modern GIS tools

Conference Paper

Full-text available

• Apr 2017

• Corey Abshire
• Dmitri Gusev
• Sergey K. Stafeyev

The Fertile Crescent was defined by the celebrated U.S. archaeologist J. H. Breasted as a semicircle spanning the territory from the southeast corner of the Mediterranean to the north end of the Persian Gulf and passing through the area located immediately north of Arabia. In the classical Geography by Claudius Ptolemy, this land corresponds to the...

A Mathematical Method for Visualizing Ptolemy's India in Modern GIS Tools

Article

Full-text available

• Corey Abshire
• Dmitri Gusev
• Ioannis Papapanagiotou
• Sergey K. Stafeyev

Ptolemy's Geography provides latitudes and longitudes for over 6,000 locations known in his time in the ancient world. Unfortunately, many of the coordinates that were chronicled at that time are known to represent a distorted view of the world. We provide a window into Ptolemy's world by systematically converting the ancient coordinates into their...

Ptolemy's West Africa Reconstructed

Conference Paper

Full-text available

• May 2005

• Lyudmila M Filatova
• Dmitri Gusev
• Sergey K. Stafeyev

We reconstructed Ptolemy's map of ancient West Africa using a modern geographic information system (GIS). Our analysis showed that the relevant information in Ptolemy's "Geography" is a compilation of data from three or more sources, including at least one version of the Periplus of Hanno, and that some of the data is apparently redundant. This fin...
