The orthophoto map is made from aerial photographs with specialized computer programs for this purpose.
An orthophoto is an image of the earth's surface that eliminates any distortion that occurs at the time of shooting as a result of the slope and terrain.
Orthophoto maps for the entire territory of Latvia are prepared in TIFF format in accordance with the resolution determined during the aerial photography period.
Aerial photography and orthophoto map preparation for the territory of Latvia takes place in accordance with the LGIA strategy. Currently, there is a 3-year period for renewing the orthophoto map.
Available orthophoto maps by preparation cycles:
- Orthophoto map of the 7th cycle (2019 - 2020)
- Orthophoto map of the 6th cycle (2016 - 2018)
- Orthophoto map of 5th cycle (2013-2015)
- Orthophoto map of 4th cycle (2010-2011)
- Orthophoto map of 3rd cycle (2007-2008)
- Orthophoto map of 2nd cycle (2003-2005)
- Orthophoto map of the 1st cycle (1994 - 1999)
- High-resolution orthophoto maps of Latvian cities and densely populated areas (1994-2002)
Orthophoto maps are made according to a certain map nomenclature
Latvian orthophoto maps of the 1st and 2nd cycle of aerial photography are prepared in the Latvian coordinate system LKS-92 TM according to the division of TKS-93 map sheets (scale 1:10 000 map sheet corresponds to 5 x 5 kilometers in nature)
Starting with the 3rd cycle of aerial photography, orthophoto maps are prepared in Latvia in the Latvian coordinate system LKS-92 TM according to the division of TKS-93 map sheets (scale 1: 5,000 map sheet corresponds to 2.5 x 2.5 kilometers in nature).
Orthophoto maps in scale 1: 2000 (in some places - in scale 1: 1000) are available in TIFF format with connection to LKS-92 TM coordinate system.
All orthophoto maps prepared by LGIA can also be prepared in MrSID format upon request.
Orthophoto maps are also available as a WMS service
Orthophoto maps up to and including cycle 6 are available In the form of open data
