Latvian DTM at Wind Farm at Grobina, Latvia

Introduction

The Latvian elevation model in 20m grid resolution is a digital terrain model produced by the Geospatial Information Agency of Latvia (Latvijas Ģeotelpiskās Informācijas Aģentūras). The model was derived from LiDAR scans and stereo-orthophotos. Spatial coverage is for the whole of Latvia. The data available in windPRO was accessed during early 2019 – and holds data with source-date 2017.
