Today the capture of GNSS data has become accessible to most people via sensors built into smartphones. Although smartphone sensors are not known to have particularly high accuracy, they provide a simple, cost-effective solution for GNSS data collection.

The use of a WebGIS is of great help for visualizing and organizing spatial and non-spatial data when planning and managing large events. It can allow visitors to easily access data and query information through an application on their phone.

The objective of this project is to develop a web-based mapping application that enables users to investigate the distribution of different soil types across Austria. The application provides users with information about the coverage of each soil type within Austria.

This exercise employs a variety of Object-Based Image Analysis (OBIA) Methods to classify a generated scene (Figure 1). This includes the use of sample-based and knowledge-based (including hierarchical) approaches. All practical tasks in this exercise were conducted using eCognition 9.
