Geographical information is a whole that contains the geographical location information and information describing a subject, such as characteristic features, measurement observations, classifications and descriptions. In addition to the location of a specific building, the geographical information can provide details such as that the building is red and has three storeys.

Internet map service
In addition to an address and service search, the Internet map service can be used to access several kinds of map materials, such as plan maps and aerial photographs from 1946 onwards. There is also a version of the service optimised for mobile devices.
Up-to-date city plan
The up-to-date city plan is a combination of legally valid city plans in the entire city area.
The base map is used as a basis for planning and municipal technology-related plans. Subjects featured on the base map include real estate information, buildings and structures, traffic routes, various terrain subjects, altitude information and nomenclature.
Land ownership map
The land ownership map is a theme map that depicts the land owned by the City.
The Lahti region guide map covers the area of five cities/municipalities (Asikkala, Heinola, Hollola, Lahti, Orimattila). The materials related to Lahti are constantly updated, while the materials related to the other municipalities are updated once or twice a year.
Orthoimages can be used as the basis for various plans together with the base map, for example. There are images from individual years between 1946 and 2014.
The office map depicts real estate divisions, buildings, address numbers, nomenclature and the traffic network.
On theme maps, certain themes or subjects are highlighted in comparison to the other contents of the map. Theme maps are usually based on guide and office maps, but the descriptions and scales vary depending on the purpose. We produce theme maps for the City's own needs and, when commissioned, to external customers.
