In this research the potential of grain production increase in Latvia is analysed. The land use analysis show that even in some nearest years it is possible to increase grain production by 400-500 thousand tons compared by 2010 level, but in 10 years period – by 1 million tons or more. This is due to increase both areas and yield. It is assessed during of the research that price above 90 Lats/t for wheat and above 80 Lats/t for barley, rye and oats stimulates grain production. Also some additional state regulation measures are recommended in the research.

The results of birth growth investigation in the 9 year old plantation on the abandoned podzolic soils of agriculture lands are assumed. The planting density was 1100; 1600; 2500; 5000 and 1000 plants per hectare. The average heights have reached 5.31 and 5.36 m, but average DBH 5.38 and 5.36 cm in the plots with 10 000 and 5000 trees per hectare accordingly. The average height has reached 6.47; 6.65 and 6.73 m but average DBH 7.17; 6.67 and 7.38 cm in the plots with 2500; 1000 and 111 trees per hectare accordingly.

Attempts to estimate the allowable maximum population density is well known in the history of game management in Latvia. Relatively permanent environmental features (e. g. landscape and forest structure) have been used for the assessment of carrying capacity of hunting grounds. Amount of the available winter feed was considered as a limiting factor for major game species in each landscape unit and forest type. While focusing on the actual abundance of feed, many other factors, including mutual interaction among species and populations, were overlooked.

Cadastral valuation model for building land has been approved by Regulations of Cabinet, and is expressed by a mathematical formula. The elements of cadastral valuation model for building land are the following: the base value of the building land, the land area under jurisdiction conditioned by the purpose of use, correction coefficient of the area, the correction coefficient accounting for the changes in the market, the correction coefficient of encumbrances and the correction coefficient of pollution.

Changes in soil morphological, physical and chemical properties as a result of establishing forest on agricultural lands were studied using as an example the lands naturally overgrowing in different periods of time by Norway spruce (Picea abies (L.) H. Karst.), silver birch (Betula pendula Roth.), grey alder (Alnus incana (L.) Moench) and aspen (Populus tremula L.). The research results showed that the soil with a texture of sandy loam and loam retains the morphological properties of agricultural land for up to 100 years.

Study was conducted in north-eastern Latvia (57° 38’ N, 22° 17’ E): in a part of Slitere National Park that was un-managed since year 1923 and affected by large storm in November of 1969. Supervised classification of Corona and Landsat 5 images of the area (in total 1646 ha) from years before and after the storm (1966–2010) were carried out and parameters characterizing the fragmentation calculated for 3 land-cover classes: forest, areas with low woody biomass and non-forest areas.

In order to ensure operation of the Cadastre, the Cadastre information system is being maintained and improved. Cadastre text and spatial data regarding cadastre objects, which are located in the territory of Latvia, are registered and maintained in the Cadastre information system. In order to specify the value of particular cadastre object, four models of cadastral assessment are developed. These models provide cadastral assessment of all cadastre objects registered in the Cadastre information system.

Cadastral map in modern market economy in different fields is marketable product. Summarized on it digital geospatial data, obtained in cadastral survey, can be widely used by many users. These data are captured using different methods of cadastral surveying therefore they have different accuracy. Land parcel boundaries are updated in compliance with data of higher accuracy. Wherewith, assessment and improvement of quality of cadastral map is very actually.
