Important! According to the Government of the Republic of Lithuania 2014 August 20 Resolution no. 791 "On the Lithuanian State Elevation System and the Lithuanian State Gravity System", the Lithuanian State Elevation System LAS07 (hereinafter - LAS07) and the Lithuanian State Gravity System LSS07 (hereinafter - LSS07) shall enter into force on 1 January 2016. & nbsp;

Director of the National Land Service under the Ministry of Agriculture in 2015 December 30 by order no. 1P-632- (1.3.) "On the Description of the Procedure for the Transition to the Lithuanian State Elevation System LAS07 and the Lithuanian State Gravity System LSS07 and the Approval of the Lithuanian Territorial Geoid Model LIT15G" approved the Description of the Procedure for the Transition to the Lithuanian State Elevation System LAS07 and the Lithuanian State Gravity System LSS07. The description is available here.

Three computer programs have been created to recalculate the heights of individual earth surface points, which you can download from the Lithuanian Spatial Information Portal.:

1. xyH772BLH07 – is designed to change the height system of ground surface points when the plane coordinates of the points (LKS 94) are known

2. BLH772xyH07 – is designed to change the height system of points on the earth's surface when the ellipsoidal coordinates of the points LKS 94 are known

3. bigxyh77h07 - "batch" type electronic calculator bigxyh77h07.exe developed for processing large arrays of ground surface points (eg LiDAR measurement results) by converting normal heights from BAS 77 system to LAS07 system

 

You can read the instructions for using the mobile applications here.

 

BAS772LAS07 – Web application for changing the height system of points on the earth's surface when the ellipsoidal or plane coordinates of points LKS 94 are known.

 

You can also download the geoid model LIT15G of the territory of the Republic of Lithuania, which is linked to LAS07, on the Lithuanian Spatial Information Portal. You can download the geoid model by entering the phrase LIT15G in the data search. You will be able to download the geoid model in 7 different formats
