The aim of this paper is to define the range of objects that may need to be accommodated in the development of a practical cadastral database, to also accommodate 3D spatial units, and permit a range of encodings to coexist. The level of geometric encoding as defined in the ISO19152 LADM provides a framework of categorization of spatial units recorded in a cadastre, whether formal or informal, historic, current or planned. The levels of encoding range from simple “text based” spatial unit to the “topology based” encoding (in both 2D and 3D).

From colonial to modern times, Brazilian agricultural property has remained immersed in a chaotic vortex of deregulation. Attempts of institutional reform - such as the Lei de Terras (Land Law) of 1850 - have been largely unsuccessful, whilst providing legal grounds for land grab by large estates and narrowing the scope of possibilities open for legitimate reevaluations of the first institutional landmark on land use and ownership in the country - the sesmarias.

Irrational water use and mismanagement are at the root of several environmental problems in the Aral Sea Basin, including secondary salinization. Pre-season leaching (February-March) is a common practice of farmers to manage soil salinity challenges. For example, farmers in the Khorezm region tend applying up to 600 mm of leaching volume to prevent accumulation of salts in the root-zone. However, excessive leaching volume causes the water tables to rise at 1-1.5 m depth which are dangerous depths.
