Detailed aerial mapping and flood impact
monitoring in the V4 region
Short project description
•
Main aim of proposed project is to incorporate UAV mapping in countries of
V4 like a new one technology of precise date collection and to create a
platform for analyzing of gained data.
•
Main target area of project are lowland regions and region of floodplains near
active rivers.
•
Project proposes to study the regions after floods, scanning and monitoring of
landslides, monitoring of slope stability, biomass monitoring, cooperation
with demarcation of border fields, documentation of archeology sites and so
on.
