The video below shows how the web application works. Web application has been done by Gulnur Khalmurzayeva during the course "IP: Application Development" as final assignment. There are five main Multispectral Image Layers, where user can digitize the geometries. First, there were set the necessary requirements for the further work. Additionally, to build this app it is used the Dojo build system, which convert a set of resources. By adding image layers and creating special functions, the user can get possibility to switch between the layers and with the help of draw toolbar, it is possible to digitize the features (point, polygon etc.). The layers connected from ArcGIS Online Services (imagery.arcgisonline.com/arcgis/rest/services/LandsatGLS). The application has been written based on samples of "Russian Federal Service for State Registration, Cadastre and Cartograph" using Web AppBuilder for ArcGIS accessing image services using the ArcGIS API for JavaScript and for digitizing objects on multispectral layers.
