Image Classification in QGIS – Supervised and Unsupervised classification

Image Classification in QGIS: Image classification is one of the most important tasks in image processing and analysis. It is used to analyze land use and land cover classes. With the help of remote sensing we get satellite images such as landsat satellite images. But these images are not enough to analyze, we need to do some processing on them. So to use these images for analysis we need image classification. In this post we will see how to download a Landsat satellite image and image classification in QGIS.

There are many software tools available for image classification such as ArcGIS, ERDAS IMAGIN, but these are not open source software. QGIS(Quantum GIS) is very powerful and useful open source software for image classification. QGIS 3.2.1 for beginners

The basic requirement for image classification is image itself but the other important thing is knowledge of the region for which we are going to classify the image.  For this either you need to do manual survey or else you can use google earth. Definitely Manual survey leads to better result.

There are two types of image classification methods..

  1. Supervised classification
  2. Unsupervised classification

Unsupervised classification is not preferred because results are completely based on software’s knowledge of recognizing the pixel. For unsupervised classification you can use KMeansclassification. In this post we will see Supervised classification only.

Download the Sample Image data for classification

Let us see how to download a satellite image first to take out sample image. One of the source is Earth Explorer  and register. If you already have an account then sign in.

Note: Please read terms and condition and usages of data.

Image classification in QGIS

Here you will see search criteria tab on your left hand side, select it. Enter date and month in the options provided, so that if you want to download image for specific season we can get that image. In rainy season cloud cover is more so it is recommended that we download a image free from cloud cover and mostly of summer of winter season to yield good results.

After zooming in to the location of interest on map click on data sets. And then search for landsat archive. Expand landsat archive option. Depending on our criteria of image we can select more than one option here. We can also set additional criteria based on our requirement.

After setting the criteria click on results. It may take some time to get the results.

Image classification in QGIS

Now analyze the results available on your screen. There are some options given for our convenience. Click on show browse overlay and check if your location comes within the image or not. An image on your screen will appear. It will take some time to display depending on your internet speed as shown below in image.

Image classification in QGIS

When you find image of your choice click on download button. Click on the download button of the file which have largest size. Don’t download other data. The download file in the folder is with extension .tar. extract that file and you will get a folder containing all the images and a text document.

Image classification in QGIS
Image classification in QGIS

You can see there are 12 images and one MTL text document. This text file is very necessary if this file is not downloaded then image classification will not be possible. We need only 7 images B1 to B7 for image classification, however we can use all the images but it will be very bulky for QGIS to handle and as you start image classification you will understand why we have used 7 images only. You may also consider to look more tutorial on QGIS.

Image Classification in QGIS :

1.) Now open QGIS and install SEMI AUTOMATIC CLASSIFICATION plug-in from the plugin option. After installation of the plugin if toolbox on the screen of the same is not showing by default then, then click view and click panels. And Check both the panels SCP: ROI creation and SCP: classification.

16.) You can set band set as per your convenience. Set the band set such that you can easily identify land cover and land use classes. For this example we are selecting the above band set. You may also set band set by zooming into your desired location and then load current value of canvas and then click apply. We can do this until we get proper colour for our image.

Image classification in QGIS

17.) Now in SCP: ROI creation panel click on new shp. ROI means Region of Interest.

Image classification in QGIS

18.) Create a shape file in the same folder with name roi or as per your wish. Click on ‘+’ sign and then Click on create a ROI.

Image classification in QGIS

19.) Now as per your knowledge of the location zoom in and create a polygon. We are creating polygon because it will take pixels of same colour with slightly difference in the value. Right click to end the polygon.

Different ways to convert Shapefile to GeoJSON – Online or Offline or API

Convert Shapefile to GeoJSON. Shapefile, ESRI made a standard vector file format which is largely adopted in the field of GIS by programmers and geographers . While GeoJSON is also an open standard format designed for Web which largely supported with GIS JavaScript API, other programming API and with GIS (Geographic Information System) software tools too, for easily rendering. GeoJSON is based on JavaScript Object Notation. Here we will explore different methods to convert the files online, or offline or with the help of API which programmers can make use of.

  • It will so the table in the next step. You can directly download the converted file or you can check it through clicking on publish button.

Convert shapefile to geojson

  • Below is the screen of published Geojson file.

Convert shapefile to geojson

Whole process is same from new uploaded file from data set or from google drive or from drop box. If you face any problem ping us at website.

You might be interested in Query on Geojson data file then try our tool IGIS Map tool.

This is presented by Engineer Philosophy pvt. ltd, working in GIS Sector an IT company. What you need to do is to just Register, login and upload only .shp and .dbf file and then export the uploaded layer to GeoJSON file by just selecting the option which appear at upper right corner in Navigation bar. You can also explore the attribute table from the website directly and filter the same which no other online tool provides.

different ways to convert Shapefile to Geojson - Online or Offline or API
different ways to convert Shapefile to Geojson – Online or Offline or API

Not only this, but you can classify the Map according to the shapefile dbf attributes and automatically classify and color it. The classified map can be exported as Scalable Vector Graphics i.e svg file.

Disclaimer: The above project is handled by me and my team and the project is in beta phase while you can definetly convert the shapefile to GeoJSON at client side securing your shapefile data. I would welcome your suggestion to improve the tool by commenting below or contacting me.

B.) Map Shapper : 

Map Shapper is the best tool which we should refer first. It is the best online tool which also handles large shapefiles and renders it quickly. Its an open source project and is licensed under MPL 2.0. Just drag the shapefile or zipped shapefile which will render the shapefile on map and can be further exported as geojson file with the option provided in tool itself.

different ways to convert Shapefile to Geojson - Online or Offline or API

With No doubt Map Shaper is much more better than any other tool for now, while the only reason why I placed this tool in second place just because the first tool was my own tool which provides more option for classifying the map, see all attributes in the data table and also exported as svg file.

2.) Offline Method – Convert Shapefile to GeoJSON in QGIS:

You must have installed QGIS  (Quantum GIS) before performing the provided steps. You may also look over other tutorial in QGIS.

1.) Open QGIS Desktop and Select Layer -> Add Layer -> Add Vector Layer or click on Add Vector layer icon appears at the upper left in the application.

different ways to convert Shapefile to Geojson – Online or Offline or API

2.) Select the zipped shapefile or any of file i.e .shp or .dbf or .shx by browing the folder. Note, that all the three files i.e .shp, .dbf and .shx file should be present in the same foder with same name.

3.) Once uploaded, the map will be rendered and showed in QGIS application. Now navigate to Layer menu and select Save As option or just from the layers panel select the layer and right click from it to select Save As option.

4.) A window pop up will opne up. From the window just select the GeoJSON format and provide the name of the file in the input box as shown in the image provided below. Save the file. It will export the file in GeoJSON format.

different ways to convert Shapefile to Geojson - Online or Offline or API

3.) Offline Method – Convert Shapefile to GeoJSON with command line ogr2ogr tool:

Firstly you need to install an ogr2ogr tool of GDAL which is a GIS utlitly command line tool so as to convert one file to another. Now if the ogr2ogr is installed globally check by simple tying the ogr2ogr in command line if it is working or not. Or if it residing in some file system you need to navigate to ogr2ogr file and type in the same in command line. Now Just type in the following:

  • “ogr2ogr -f GeoJSON -t_srs crs:84 [name].geojson [name].shp”

To get more option list and format you may see this gdal org link.

This tool will be helpful if you want to convert bulk files from shapefile to geojson. You can refer the .sh script found at github.

4.) Convert Shapefile to GeoJSON -API or library:

Shapefile is a binary file and cannot be viewed directly in notepad or textpad as like with GeoJSON file. So if you want to create your own API, to convert Shapefile to GeoJSON you should first have a knowledge of how to read the binary shapefile. You may refer to some of the articles which I have written some post which would help you to get the basic knowledge to know the format of files and read.

You may further refer to some of the best Shapefile to GeoJSON converter API which is open source project: :  This is dedicated library to convert to GeoJSON, created by Marc Harter and Licensed with MIT. : This library is also MIT Licensed and is inspired by the above wavded library which uploads zipped file of shapefile. The library provided an example to use with leaflet js. : Map Shaper as desricbed above is licensed under MPL 2.0 and can be very useful if you want to convert to GeoJSON as well as TopoJSON.

Hope this article helped you. If are facing some problem in converting the shapefile to geojson do comment below with the problem statement. We will definitely look over that. Also you can provide your valuable comment below if you are using any other library or tool to cover the same.
