Lossless Data Compression of Grid-based Digital Elevation Models: a Png Image Format Evaluation
At present, computers, lasers, radars, planes and satellite technologies make possible very fast and accurate topographic data acquisition for the production of maps. However, the problem of managing and manipulating this data efficiently remains. One particular type of map is the elevation map. When stored on a computer, it is often referred to as a Digital Elevation Model (DEM). A DEM is usua...
متن کاملFruit Fly Research and Development in PNG
Many cultivated and natural fruits play an important role both in food security and in meeting nutritional requirements in households throughout PNG. Fruit fly species of the family Tephritidae account for significant preharvest and postharvest food losses, and a reduction of these losses will improve food availability at household levels. The Papua New Guinea Fruit Fly Project (PNGFFP) has con...
متن کاملOn the Collision between Two Png Droplets
In this article we study the interface generated by the collision between two cristals growing layer by layer on a one-dimensional substrate through random decomposition of particles. We relate this interface with the notion of β-path in an equivalent directed polymer model and, by using asymptotics results from Baik and Rains [3] and some hydrodynamic tools introduced by Cator and Groeenenboon...
متن کاملTile mapping
At the high resolutions attainable with the new generation space-borne sensors, the focus moves increasingly from spectral characteristics to geometric features. This trend is even more evident for urban areas which tend to show an unpaired concentration of linear features with respect to any other land cover. This naturally applies to both optical and radar images, and suggests one may use loc...
متن کاملOne Tile to Rule Them All: Simulating Any Tile Assembly System with a Single Universal Tile
In the classical model of tile self-assembly, unit square tiles translate in the plane and attach edgewise to form large crystalline structures. This model of self-assembly has been shown to be capable of asymptotically optimal assembly of arbitrary shapes and, via information-theoretic arguments, increasingly complex shapes necessarily require increasing numbers of distinct types of tiles. We ...
