A Short Introduction to GIS

What is GIS?

GIS stands for Geographic Information Systems.

This system utilises technology to show information about locations on the earth's surface. 


Examples of Geographic Information Technologies:

  • Global Positioning Systems (GPS)
    • It is a satellite-based navigation system that provides location and time information anywhere on or near the Earth.
    • It has numerous applications such as navigation, surveying, mapping, and tracking, among others.
  • Remote Sensing (RS)
    • It is the process of collecting and interpreting information about the environment and the Earth's surface using sensors that are not in direct physical contact with the object or area being studied.
  • Geographic Information Systems (GISy)
    • It is a computer program that is used to collect, store, manage, analyze, and display geographically-referenced data.

GIS Application Sector:
  • Local Government
  • Business, Real Estate and Marketing 
  • Public safety, Military and Defense 
  • Natural Resource Exploration 
  • Civil Engineering / Utility 
  • Transportation
  • Public Health and Epidemiology (Heath Care)
  • Geospatial Industry
  • Scientific Research
  • Environmental Sciences
  • Education Administration
  • Political Science
  • Urban Planning, Management and Policy

Project 3: Soil Erosion Analysis

Image
Upon initial observation, Kampung X is currently facing a severe issue with erosion. As a researcher assigned by the Department of Agriculture Malaysia, my responsibility entails 1the task of conducting studies on the soil erosion rate from 1990 to 2010. The Revised Universal Soil Loss Equation (RUSLE) is used as it can estimate erosion and plan conservation measures by predicting the amount of soil loss in specific fields with specific slopes. This equation utilizes five key factors that can be assigned numerical values to predict the soil loss at a given location. The soil loss is calculated as follows: A = R × K × LS × C × P   where A is annual soil loss (tons/ha/yr),  R is the rainfall erosivity factor,  K is the soil erodibility factor,  LS is slope length and steepness factor,  C is cropping and management factor, and  P is conservation supporting practices factor (Yoder and Lown, 1995) Rainfall erosivity (R) factor is the index that measures the erosion force of specific rainfa

Vector Geoprocessing Tools

Image
A geoprocessing tool is one that systematically manipulates either the geometry or the attribute information or both of a vector GIS data file. It is used to perform various spatial operations and analyses on vector data. These tools allow for tasks such as buffering, clipping, merging, intersecting, dissolving, and more. They provide the means to extract, transform, and analyze data within a geographic context, facilitating effective spatial analysis and decision-making processes.   The photo above clearly shows the function of the 6 basic toolkits. Basic six toolkits Buffer - creates a geometric area around vector features by using points, lines or polygons (input) at a specified distance of a feature or features (buffer width) - can create variable distance buffers based on attribute value  - use equidistant projection to center the point from that point, know the scale well and can draw buffer Clip   - subset tool - large dataset to clip down into smaller subset/dataset - clip oper

Project 2: Land use change analysis

Image
    To analysis the land use change by using GIS The land use change map  for the Year 1990 to 2000, 2000 to 2010, and 1990 to 2010 are created using QGIS . The graph of land use changes for the Year 1990 to 2000, 2000 to 2010, and 1990 to 2010 are drawn by using Microsoft Excel .  Diagram above shows the map of land use change from the year 1990 to 2000. Graph above shows the area change (hectare) of land use change from the year 1990 to 2000. Diagram above shows the map of land use change from the year 2000 to 2010. Graph above shows the area change (hectare) of land use change from the year 2000 to 2010. To get a better visual for soil erosion change for the past 20 years, a map and a graph is drawn.  Diagram above shows the map of land use change from the year 1990 to 2010. Graph above shows the area change (hectare) of land use change from the year 1990 to 2010.      From the graphs, the area of forest is the largest and the orchard has the second largest area no matter from the y
