The 5th UN-SPIDER RSO-Meeting in Vienna, Austria
Ukrainian RSO has developed several recommended practices on the usage of satellite data for disaster risk management and emergency response. These practices were discussed at the 5th UN-SPIDER RSO-Meeting 13 and 14 February 2014 in Vienna, Austria, and presented on the UN-SPIDER Knowledge Portal.
The first practice is devoted to the use of SAR satellite imagery for flood mapping. The practice shows the use of ESA NEST software for pre-processing and processing of SAR imagery using a threshold method for deriving flood extent. The QuantumGIS software is used to visualize the results of image processing.
The second practice is focused on using NDVI values derived from MODIS to build a linear regression model for crop yield forecasting. It is shown how QuantumGIS software can be used to extract average NDVI values over administrative regions. This data is further integrated with official statistics on crop yield to build a regression model. For this purpose any statistical package can be used.
