GIS (Geographic Information System)

  

GIS stands for Geographic Information System. It is a system designed to capture, store, manage, analyze, and present spatial or geographic data. GIS combines hardware, software, and data to provide a wide range of capabilities for understanding and working with geographic information.

Here are some key components and concepts related to GIS:

• Spatial Data: GIS is primarily concerned with spatial or geographic data, which includes information tied to specific geographic locations on the Earth's surface. This data can be in the form of points, lines, polygons, and raster images.

  GIS system maintains spatial data & attribute data. Spatial data (where)

  • specifies location
  • stored in a shape file, geo-database. 
    
• 
  Hardware: GIS systems often require specialized hardware, including computers with sufficient processing power, storage capacity, and display capabilities. In some cases, specialized input devices like GPS receivers and digitizers are used to collect spatial data.
• Software: GIS software is used to create, edit, analyze, and visualize geographic data. Popular GIS software packages include ArcGIS, QGIS, and Google Earth.
• Data: Geographic data is at the core of GIS. This data can come from various sources, including surveys, remote sensing, GPS devices, and existing databases. GIS can integrate data from different sources into a unified system.
• Data Layers: In GIS, data is organized into layers, each representing a specific type of geographic information. For example, a GIS project might have separate layers for roads, land parcels, rivers, and population data.
• Spatial Analysis: One of the primary functions of GIS is to perform spatial analysis. This includes operations like buffering, overlaying, proximity analysis, and spatial modeling to gain insights from geographic data.
• Map Production: GIS is often used for map production and cartography. It allows users to create maps with various symbols, labels, and thematic representations to convey spatial information effectively.
• Geocoding: GIS can convert addresses or place names into geographic coordinates (latitude and longitude) or locate addresses based on coordinates. This is known as geocoding and is useful for tasks like mapping and navigation.
• Remote Sensing: GIS can incorporate data from remote sensing technologies such as satellites, aerial photography, and drones. This data provides valuable information about the Earth's surface.
• 
  Spatial Queries: GIS enables users to perform spatial queries, allowing them to retrieve specific geographic information based on criteria like location or attributes. For example, finding all the schools within a certain distance of a park.
• Visualization: GIS software provides tools for visualizing geographic data through maps, charts, and 3D models. Visualization aids in better understanding and decision-making.
• Decision Support: GIS is used in various fields, including urban planning, natural resource management, environmental monitoring, transportation, and emergency response, to support decision-making processes by providing spatial insights.

GIS has a wide range of applications in both the public and private sectors, and its versatility makes it a valuable tool for managing and analyzing geographic information to solve complex spatial problems.

Attribute (descriptive) data (what, how much,when)

• specifies characteristics at that location, natural or human-created.
  
• stored in a database table .

Advantages of GIS

• Effective Planning
• Better Information Management
• Enhanced Mapping Capabilities
• Improved Communication
• Manage Natural Resources
• Efficient Design
• Better Marketing Planning
• Optimise Public Transportation
• Scientific research employs GIS 
• Asset Management etc.

There are several GIS software packages available, ranging from open-source and free options to commercial solutions. The choice of GIS software often depends on the specific needs of the user or organization, as well as factors like budget and available resources. Here are some of the most popular GIS software options as of my last knowledge update in September 2021:

ArcGIS:

Developed by Esri, ArcGIS is one of the most widely used commercial GIS software packages. It offers a comprehensive suite of tools for data creation, analysis, visualization, and management. ArcGIS includes desktop, web, and mobile applications.

QGIS (Quantum GIS):

QGIS is a free, open-source GIS software that is powerful and user-friendly. It has a large and active community of users and developers, which has led to the creation of numerous plugins and extensions. QGIS is available on multiple platforms, including Windows, macOS, and Linux.

GRASS GIS:

Geographic Resources Analysis Support System (GRASS GIS) is an open-source GIS software package known for its advanced geospatial analysis capabilities. It is particularly popular in the scientific and research communities.

MapInfo Professional:

MapInfo Professional is a commercial GIS software known for its ease of use and is often used for business and location-based analytics. It provides tools for mapping, analysis, and data visualization.

Global Mapper:

Global Mapper is a user-friendly GIS software that combines spatial data management with analysis and visualization capabilities. It supports a wide range of data formats and includes 3D visualization tools.

Google Earth Pro:

Google Earth Pro is a free desktop application that offers basic GIS functionality, including the ability to import and visualize geographic data. It is user-friendly and widely used for educational and basic mapping purposes.

PostGIS:

PostGIS is not standalone GIS software but rather a spatial database extension for PostgreSQL. It adds spatial data capabilities to the PostgreSQL relational database, making it a powerful choice for those who need to manage and analyze geospatial data within a database environment.

Mapbox:

Mapbox provides tools and services for building custom maps and applications. It's commonly used for web and mobile mapping applications, allowing developers to create interactive maps with custom styles and data.

OpenLayers:

OpenLayers is an open-source JavaScript library for building web-based maps and GIS applications. It provides a framework for displaying and interacting with maps in web browsers.

GeoServer:

GeoServer is an open-source server software that allows users to publish and share geospatial data over the internet using various standards like WMS, WFS, and WCS.

These are just a few examples, and there are many other GIS software packages available, each with its own strengths and focus areas. The choice of GIS software depends on your specific needs, budget, and familiarity with the software. 

Android on Virtual Box

Installing android on PC is really helpful on some case when you are testing app or any reason you want to run the app. If you need more than one device along with the device you have on your hand is create a virtual device. It would be the best way to run the app.

To solve this problem you can create a virtual device on your pc using the virtual box. You can download the android x86 os on your pc or virtual box to make this happen.

Just follow the few steps to create it.

1. Download the Disk image from THIS LINK. this will take you to the  URL https://www.android-x86.org/
2. Then Download the Virtual Box using THIS LINK or https://www.virtualbox.org/
3. Then Create a Virtual Machine using Followings:
   Name: Android (anything you wish)
   Machine Folder: (Leave default)
   Type: Linux
   Version: Other 64-bit
   
4. Then Link the image file on the machine as you start
   
   
5. Give put desirable amount of RAM. I think 4096 MB is enough for 4GB.
6. Create a virtual Hard Disk
7. Then Choose the Hard Disk File type as VDI (Virtual Box Disk Image)
   
   
8. Storage on physical hard disk 'Dynamically allocated'
9. File location and size around 32 GB

Now the time has come to run the Virtual device,

Go to settings and adjust the followings,

• SYSTEM 
• Motherboard
• Pointing Device> PS/2 Mouse
• Processor
• Processor(s) : 4
• DISPLAY
• Screen
• Video Memory: 128 MB
• Graphics Controller: VBoxVGA
• Acceleration: Tik the Enable 3D acceleration

Then Click OK and save it.

Next, Load the Downloaded iso file and run the machine.

As the machine runs the Go to Advance Option.

> Advance Option

    >Auto _Installation-Auto Install to specified Hard disk 

        >Auto Installer Option (YES)

            >Run Android-X86

If you have a fucing Fate then a black screen with console# may appear or it will stuck then you need to close the virtual box and Power off the machine.

Start the Machine again and Go to Advance Option and Boot from the Local drive.

    >Hovering the first option press 'e'

then replace this line 

grub edit> kernel /android-9.0-r2.kernel force root=/de/ram0 S><dev/ram0 SRC=/android-9.0-r2

into

grub edit> kernel /android-9.0-r2.kernel nomdeset xforcevesa root=/de/ram0 S><dev/ram0 SRC=/android-9.0-r2

Then press enter and press 'b'

Now your machine is ready to run.
