ask the user for the name of the output file with the NDVI values. ask the user for the image the NDVI should be calculated from. For this we want to create a small program that calculates the NDVI (NDVI = (NIR-Red)/(NIR + Red)).įor a start our program should be able to: This tutorial shows you how to create an EnMAP-Box application using the EnMAP-Box and hubAPI programming interfaces. Use Strg and click on methods to jump to their definition or hover over for a description. Use the hubAPI documentation to get familiar with the basic concepts of application development. In case of very strange IDL behavior: restart the IDL workbench. In case of strange IDL behavior: use the reset button. Don’t forget: you need to re-compile your *.pro files to make changes visible. Create test routines with sample data to verify your routines, e.g. Use Shift+B to toogle breakpoints and stop your code for debugging. Use this to check if your app runs correctly without development license. This opens the EnMAP-Box using the *.sav files only without compilation of *.pro-files. Start EnMAP-Box in IDL virtual machine mode. Remove application folder (de-installation). For installation they just need to put it into their own /enmapProject/applications/ directory and re-start their EnMAP-Box.Ĭompile application, create documentation, copy files to application folder (installation). Copy the /enmapProject/applications/MyApp folder to share it with other EnMAP-Box users. Copy your Applications Source Code Folder to share your project with other EnMAP-Box developers. For distributing your application you can either. Call IDL> myApp_make again for compiling your application and copying *.sav files and supporting documents to the application folder:. Just modify the IDL code, manuals etc. 
… or open supporting documents via Help > MyApp.Now you can run your application from the EnMAP-Box menu bar via Applications > MyApp > MyApp Application.
