GIS

GIS means Geographical Information System this system I used for data visualization used by geographical lovers and developers to show their data on it, There are lots of GIS-based software which allows getting geographical input data in form of raster and vector, raster data is nothing but special data which used colors to show its range and vector data are points, polygon data which shows a particular value on the map

GIS

So let's talk about Q-GIS open-source software to get an idea of how a GIS-based system works

The first thing to do with this software is to collect data

your data can be in the form of raster or vector so to identify this data we used extensions for vector is .shp file and for raster, it is .tiff file

raster v/s vector

so understand the data, lets assume you got one project where you have to show to people about covid-19 active, dead count using the map for India so you have this data in excel form or CSV file

You have made the layout of the website and to show this data you have a GIS server here you have to insert all the CSV data in form of vector to show its Information

covid data visualization using GIS

So here we go special geographic data need a special server which is a GIS server we can insert data of covid active and covid e dead cases

now let's understand how you can convert CSV data into vector

1. install QGIS
2. open new project
3. select on insert data
4. add CSV file
5. save it as .shp file

that's it your data is converted into point data

and this .shp file you can add into Geoserver and using Postgres SQL you would able to sow this data into your webpage

same you can add your raster data into it the only difference is raster data of any surface you need to download from a geographic special data website

I wanted to share with you some basic information about GIS because its a very easy to grasp and you can roll on this technology on any website to show your data and virtualized it better for user

Thank you
