Thank you!Įmmanuel Jolaiya is a GIS analyst, data scientist, and GIS development enthusiast with a keen interest in transforming data into insights that aids in making informed decisions. Woo-Hoo! You made it! Thank you for reading along, If you found this tutorial article useful kindly share with your network. This is obviously the tip of the iceberg, I’ll show you how to turn the model we built above into a reusable tool in a future tutorial. On the menu bar, hover on Geoprocessing, select M odelBuilder from the drop-down menu to open the model builder window. Create a new map document or open an existing map document.ģ. If you have all the requirements in place:Ģ. Otherwise, you can check here on how to install ArcMap 10.x and here to download Landsat imagery from the USGS data archive. I’m assuming you have the software installed as well as the data downloaded. Goal: Mask the study area from the Landsat imagery and calculate NDVI for the study area. Software: ArcMap 10.7 ( don’t worry, all ArcMap versions have ModelBuilder, so you can still follow along : ) )ĭata: Landsat 8 OLI/TIRS and a feature class (study_area.shp). In this demonstration I’ll be using the following Specifications of software and data used: Yours can be a different reason but the common thing here is that we are trying as much as possible to optimize our time and energy and avoid carrying out repetitive tasks. You might be wondering why I want to do this, well, the simplest answer is because I know I’ll most likely carry out similar analysis in the nearest future, so to optimize time in future projects and avoid opening the raster calculator every time, I’ll be designing this model. In this practical demonstration, I’ll be building a model for masking a study area from imagery and calculating the NDVI for the study area. But, in the meantime, enjoy this :) Practical Demo I hope to start a YouTube channel soon, particularly for long tutorial articles like this. Not to scare you, but this is going to be a really long tutorial. In this article, he will be showing users how to use ArcGIS ModelBuilder to develop a model for for analyzing and manipulating GIS Data.

In the previous article in this series, Emmanuel Jolaiya provided an introduction to ArcGIS ModelBuilder.
