How to Predict future landuse using GIS

Prediction of future landuse is an easy task. You Just know basic of GIS. Let's Think how urban area will grow. 
Growth Depends on Some factors as:

  1. Distance between two cities
  2. Distance from Roads
  3. Elevation of City
  4. Near to outer area of city
  5. Trend of change from Agriculture to Urban, or Forest to Urban
  6. The actual landuse
  7. Rate of change
We can predict future landuse in two ways, Using Regression model or By CA Markov Method with Machine learning approach to solve complex problems. 

So CA Markov is best to predict with MLP and Neural Network approach. This way we train our model with 50% learning and 50% testing approach. But any learning accuracy between 40% to 70% will provide accurate results. It depends upon how we are getting output results. Each time after modification check results by comparing to real landuse if it matches at least 70% then continue to predict for future.  All task are too easy some work need to do in ArcGIS and some in Terrset Model. Both are NOT open source.

Learn ArcSWAT Model Watershed Simulation using GIS - Complete Tutorial


ArcSWAT is Watershed simulation model in GIS. It uses weather and climate data to calculate water flow at outlet Watershed. Its very Easy also. Most of Research paper accepted who used SWAT Hydrological Model. It works with ArcGIS 10.1-10.4.  It used to calculate water flow for ungauged catchments.  Never think simulation is difficult, if learn in proper way its like Just Word. Surprise your friends by Publishing a Good paper. 
In this course you will learn other related advance task of GIS also, like preparation of Soil Map, Mosaic of DEM etc.
  • Discharge in Cubic meter Per Second at Watershed outlet, Daily Monthly and yearly
  • Watershed and Sub-watershed delineation using SWAT
  • Configure SWAT model for any Area in World
  • Groundwater Recharge
  • Sediment at outlet (Soil Erosion)
  • Water Yield
  • Preparation of Soil Map and DEM Mosaic for large Watershed
  • Water Quality
  • Simulation of Daily Data
  • Data preparation for SWAT
  • Updating SWAT Database
  • Understanding advance task of Simulation
  • Working with daily data and working without data
  • Configure Data set for India
  • Evaporation and Evapotranspiration
  • Watershed Simulation
  • Successfully run The SWAT Model
  • Preparation of Soil Map of Any country
