This paper describes creating of the digital relief of Latvia. Its plane approximation step is 500 m, with the hydrographical network included. As the initial data for creating the relief, two data sets provided by the Latvian Geospatial Information Agency (LGIA) were used. This work is targeted on preparing and checking of these initial data. Problems of acquiring elevation data for rivers and lakes are considered. The geospatial data of LGIA, which were used for creation of the digital relief by the Environment Modelling Centre (EMC) of Riga Technical University (RTU), are reviewed. The methods for identifying of faulty geospatial data are considered. Two reliefs – the LGIA provided digital relief and the EMC created digital relief are compared. The comparison shows that both reliefs are not perfect, due to faulty initial data and the large plane approximation step used.
