The current article presents two map projections used in Romania mainly for military purposes, namely Lambert-Cholesky (from 1917 to 1931) and Gauss-KrпїЅger (from 1955 to 1971). After a brief description of their individual characteristics and particularities of application in our country, a comparison of the distortions produced by both projections was presented in order to emphasise their various advantages. The accuracy of relief representation using contour lines on maps drawn to scales of 1:20,000 and 1:25,0...

With a cultivated area of over 2x108ha, wheat is the largest crop worldwide by cultivated surface. For wheat crops, the production suffers loss caused by weeds, and depending on the weeding level, the fertilization level can surpass 50% (1). Weed management is just one of the technological components present in any crop technology. Given the biological particularities, wheat crop is mainly weeded with dicotyledonous species. The objective of this paper is the comparative evaluation of the classic method for determ...

The management of construction waste it is at an early stage in urban areas and lacking in rural areas where this fraction is frequently uncontrolled disposed on public lands. Despite the fact some items of construction waste are considered inert for the environment (soil, concrete) it also contains hazardous items (paint additives, cans, and containers) or recyclables (plastics, metals, wood). Potential recovery of this waste stream is high if it is properly managed. The paper estimates the potential amounts of w...

Colours have a unique position among all the principles of map design and visualisation of spatial data. Colours are a part of map language, and they carry the information value. Also, colours are used for creating the hierarchy of map elements by distinguishing the important from the unimportant. Furthermore, colours are a part of the whole graphic design of any visualisation of spatial data. There is a huge number of papers focusing the theoretical basis of colour use in cartography and spatial data visualisatio...

Atlas production is largely a joint work of cartographers and designers.
