Sweden is a country with few native tree species. According to Govt. 2007/08: 108, exotic tree species may be seen as an opportunity to increase the growth of tree volume in Sweden. Potential areas where explored In this work for cultivation with Pinus contorta var. latifolia Engelm., Larix sukaczewii Dylis, Abies lasiocarpa (Hook.) Nutt., Populus × wettsteinii Hämet-Ahti (tremula x tremuloides) and Picea mariana (Mill.) Britton et.al.

Lantmäteriet (the Swedish mapping, cadastral and land registration authority) has been laser scanning Sweden since 2009. From the laser scanned data a digital elevation model (DEM) in grid format, with a resolution of 2 m, is produced. This DEM is called GSD-Höjddata, grid 2+ and from its data and the laser point cloud itself (in the form of a las-file) contour lines can be extracted. Lantmäteriet has not yet done this, but plans to update the contour lines in their cartographic products exist. If this is to be done in a satisfactory way an evaluation of different methods for it is needed.

The aim for this essay is to identify and distinguish the metal casting of Uppåkra during late Iron Age by examine related material that primarily consist of finds made with a metal detector. I intend to, by analysing maps, concentrations in the detector material and probable constructions within the settlement, find patterns that can indicate a metal casting activity. The results of the essay show that a number of concentrations can be seen and that they both indicate metalworking activities and to some degree a structural specialization in the settlement. The exclusive artefacts also indicate that Uppåkra was a settlement with over-regional functions when it comes to traditions dealing with metal casting..

The aim of this study was to map the prevalence of aeolian sand dunes in Västerbotten, northern Sweden to find dunes formed during earlier deglaciation phases, which was then preserved in cold-based conditions during the youngest stadial of the Weichselian glaciation. These preserved dunes were expected to be covered by a layer of till and have a rather faint morphology compared to dunes formed during the Holocene. Consequently, high resolution LIDAR-derived images from the Swedish mapping, cadastral and land registration authority (Lantmäteriet) was used to detect the dunes throughout an area covering most of Västerbotten, above the highest coastline and below the mountain range. The analysis resulted in several new findings of aeolian dunes compared to the findings in the quaternary soil map created by the Geological Survey of Sweden. Despite the fact some of the dunes at the LIDAR-derived image had a strange faint appearance, it was quickly evident during the fieldwork that the aeolian sand was not covered by till on any of the dunes visited.

With the days DGPS-technology can a position of 5 centimetres decides. With this exactly position is the technology very interesting for the agriculture. I think this technology can come more and more in the future. You can also move the fact and information further to the spreader, sprayer and seeders. If the combine is equipped with harvest accounting, can you with help of the system make harvest maps.

The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.

Being able to take a decision on an area you've never seen is a difficult task. It is also complicated to introduce an environment in the best way to benefit its purpose. This study focuses on the differences people notice between 2D and 3D models. To make it more concrete, the study has been linked to a case study called Ha?lsans va?g 255.

This study has a double purpose. First, it explores and maps out the use of quantitative key indicators in social performance reporting within a microfinance portfolio. This was done on behalf of Storebrand Asset Management, who would like to aggregate and report the social results of their microfinance investments to their customers. The study concludes that the extent of social reporting and types of indicators used varies, meaning that it is hard to aggregate data for use in further reporting. Thus, the work towards the goal of social reporting has only just begun.

The purpose of the essay Multi criteria analysis of potential conflicts concerning land use planning - natural stone mining in Lysekil municipal is to study possibilities and limitations in GIS based multi criteria analysis as a tool for land use planning. How GIS based multi criteria analysis can be implemented to localize potential conflict areas between natural stone mining and other land use activities and what advantages and disadvantages the method holds are the main issues of this study. The essay studies these questions through a case study, concerning the geographical area of Lysekil municipal in western Sweden and problematizes the interest of natural stone mining in relation to other land use interests. A literature study was carried through, concerning multi criteria analysis and planning. After collecting and processing of data the multi criteria analysis could be implemented in the ArcGIS tool Weighted Sum.

Subsurface Scattering är nu för tiden väldigt populärt inom datorgrafik och används inom de flesta filmer och spel, men det är ingen enkel process för att uppnå ett bra resultat. Därmed kommer forskningen och utvecklingen fokuseras på subsurface scattering i verkligheten och inom Autodesk Maya med inbyggda renderingsmotorn mental ray. Subsurface scattering via mental ray kan lösas på flera olika sätt och nödvändig information om subsurface scattering shaders och andra noder kommer att förklaras för de metoder som känns till som lightmaps och photon maps. Det kommer även finnas en tredje metod som fokuserar på passrendering av en lightmap shader. Metoderna bevisar sedan vilken metod som anses vara den bästa för situationen man befinner sig i..

?Are the headwaters streams at the right position in the map? is a study that has been performed on behalf of Holmen Forest, region Örnsköldsvik. This study will be the basis for deciding if the Hydrology Layer Property map or Holmen Forest map will be used for planning nitrogen fertilization in forestry. The background to this study is that nitrogen fertilization near water will increase the risk of nitrogen leaching out into the water systems, which has a negative impact on the environment. The headstreams positions have been recorded in the field with a GPS and the data analyzed in the geographic information system ArcMap.

This paper deals with the development of scientific geography during Antiquity from its mythical background before the seventh century BC to Claudius Ptolemy during the second century AD. The main focus is on questions concerning the shape of the earth, its place in the universe, size and mapping of the earth. Already before 400 BC, the idea of the earth as a globe was firmly estabished. During classical time, Aristotle used empirical and rational arguments to prove that the earth was a sphere and that it was situated motionless in the center of the universe. In the third century BC, the first reasonably correct measurements of the circumference of the earth was carried out by Eratosthenes.

IP-adresserna under IPv4 är inte tillräckliga och har på många delar i världen redan tagit slut. IPv6 erbjuder många fler tillgängliga adresser och övergången till protokollet har redan börjat. Det Gävlebaserade företaget Interlan erbjuder en tjänst som kontrollerar om kommuner och myndigheter i de nordiska länderna är nåbara via IPv6 samt om de är säkrade med DNSSEC. Denna rapport beskriver jobbet med att förbättra och göra deras tjänst anpassningsbar för flera länder. Processen som beskrivs är parametriseringen av skripten som samlar data, skapandet av en databas att lagra data i, och ändringar till hur data presenteras så att det går att lägga till flera länder..

This thesis presents the results from a osteological analysis and a GIS-study aimed to examinedifferences in the located animal bones in different areas of the excavation site of Ajvde.The osteological material came from five excavated square meters on the site and was comparedwith osteological results from other researchers from different areas to create overview and try tosee differences between the areas.The GIS-study took data from all animal bone material excavated on the site, a total of about 2300kilos, and presented them in maps of spatial distribution for each layer (pictures 4, 5, 6 & appendixpicture 1) to see if there were any clusters of activity and changes between the layers. The dating ofthe culture layer and the burial field (pictures 7 & 8) were presented in maps to see if they could becorrelated with what was seen with the animal bones. Pictures of different shorelines were alsopresented (picture 9) to compare with the results that were seen in the changes of animal bones fromdifferent layers.The results of the GIS-study have shown that the activity on the site have moved over time alongthe hight differences of the land. The earlier layers show activity only on the higher elevation butlater moves down, and in the upper layers activity have been all over the excavated area. Clusters ofanimal bones were seen in the so called ?black areas? of the sites (shown in picture 2) but also otherareas contained a lot of animal bones.The results of the osteological analysis have shown that there are differences in what species arefound in different areas.

In the middle of the 19th century was Calluna heath the major nature type in Halland, but the remaining parts today is only 1 500 hectares which is a 99 % decrease of the Calluna heath mainly due to an increase in forest plantations and arable fields. I have made a quantitative study how the Calluna heath of Grönabur & Sandsjöbacka has changed between 1841 and 2005 and why it didn?t disappear in the same manner, as it did in other parts of Halland. The studying of original sources as historical maps, literature and by doing field visits has been significant for the final result. The main reason for the different development of the Calluna heath in the investigation area (69 % decrease), compare to elsewhere in Halland, is the establishment and management of a nature reserve..
