map of latvia

AS "Latvijas valsts meži" offers for everyone interested in a freely accessible contour lines vector layer. The contour lines cover almost half of the territory of Latvia (more than 32 900 km2), they completely cover Kurzeme, most of Zemgale, as well as a small part of Vidzeme and Latgale. The layer contains information about contour lines with a 2meter step. The data is prepared automatically using a 15-meter terrain model, created from the LIDAR point cloud ground class points (aero laser scanning data from 2013-2035 LGIA). Data are available in the LAS - 2000.5 normal height system. Automatically generated data in loosely flat ground relief areas forms loops, connecting as many as possible high value points of equal value. Such loops in contour lines data are observed on the waters, bogs and plains. In the moment, manually-specified data are not available, as it requires a great amount time resources of specialist. Manually corrected data, higher detail, and lower horizontal step data we provide as a paid service.

Data will be supplemented by the availability of LGIA aero laser scanning data for new territories. For those interested in getting information about adding new data and services, as well as about service malfunctions, we invite to fill out the email form available here.
