Respected sir/mam,
I have using satellite image of Landsat 8 and 5 for LULC classification. I am confused that which software and method are the best for LULC classification?
Please help me.
Thanks and Regards
It depends upon your interpretation which is a key to accuracy and can be improved using indices and various online extraction tools like Settlements from OSM.
You can utilize a series of software to this end but personally speaking ENVI works wonders in this regard
Generally speaking, given the diverse range of climate systems and terrain conditions in different areas, there is no conclusive agreement on introducing a specific approach that would provide the most accurate results in all circumstances. However, RF and SVM usually show acceptable performances. I would recommend you to read following papers to get more information (codes are also available):

Amin Naboureh Thank you for your response. I will definitely gone through those papers.
Most GIS and RS software have the standard classification methods (ArcGIS, QGIS, ENVI, Eedas etc).
Dear Pritiranjan
I would check out the Queensland, Australia, SLATS website. https://www.qld.gov.au/environment/land/management/mapping/statewide-monitoring/slats . The people running this are experts and no doubt will be happy to answer questions directly.
Dear Pritiranjan Das
Most of the Geographic Information Systems programs have good classifiers, it's a matter of testing and seeing if you get the result you want (ArcGIS Pro, QGIS).
On the other hand, you have programs that were created for digital image processing (PCI Geomatics, ENVI, TerraAmazon), in which you find more options. These programs also have the basic GIS tools.
Finally, the trend is for these processes to be carried out in the cloud to streamline processes, here a very good tool is Google Engine.
Note: My program references are based on what I have used, surely there are other programs (possibly with better results)
Hi Pritiranjan Das,
You can use Google Earth Engine for LULC Classification using machine learning algorithm. You can easily find the code for that in GEE itself. You just have to give the training data sets according to the Landsat imageries. Most importantly, try different band combinations for identifying the classes keeping the base map as reference. It will take less time for such classification. You can even check the training accuracy and validation accuracy with the preparation of the LULC map using GEE.
Hi Pritiranjan Das,
Im using ERDAS for classification and using google earth imagery for comparison
Dear Pritiranjan Das ERDAS Imagine is a perfect image classification software. I agree with others that all GIS software (Open or licensed) have standard image classification algorithms but ERDAS Imagine is exceptionally made for image classification. So, I suggest you do image classification using ERDAS Imagine. There are options available, you can do either supervised or unsupervised classification based on the applicability of your research. I prefer supervised image classification using the maximum likelihood classifier for my studies.
Gibji Nimasow Thank you sir for your valuable response, i must follow your preference.
Regards.
I suggest you to use Google Earth Engine.
Please refer the link below for LULC classification using Random Forest

You can also use different ML algorithm for the classification in GEE easily.
