Crop identification and area estimation through the combined use of satellite and field data for county Durham, northern England

Shueb, Saleh Saber January 1990 (has links)
This thesis investigates the use of combined field and satellite data for crop identification and area estimation in County Durham, Northeast England. The satellite data were obtained by the Thematic Mapper (TM) sensor onboard Landsat-5 on 31 May 1985. The TM data were geometrically corrected to the British National Grid and the county boundaries were digitized in order to apply the methodology used in this study on a county basis. The field data were obtained by applying a stratified random sampling strategy. The area was subdivided into five main strata and forty four 1km(_^2) sample units were randomly chosen and fully surveyed by the author using a pre-prepared questionnaire. The field area measurements were taken and the final hectarage estimates were obtained for each crop. The research demonstrated the ability of Landsat-TM data to discriminate between agricultural crops in the study area. Results obtained emphasised that satellite data can be used for identification of agricultural crops over large geographic areas with small field sizes and different environmental and physical features. A land-cover classification system appropriate to the study area was designed. Using the Landsat-TM data, the study produced a classification map of thirteen land-cover types with more than 80% accuracy. The classification accuracy was assessed quantitatively by using the known land-use information obtained from the sample units visited during the field survey. The study analysed the factors which influenced the degree of separability between different agricultural crops since some crops were more clearly identified than others. Using a double sampling method based on the combination of both Landsat- TM and field data in regression analysis, a hectarage estimate was produced for each crop type in County Durham. The results obtained showed that the regression estimator was always more efficient than the field estimator. Crop area estimated by regression reduced the imprecision in all strata and was more efficient in some strata than others. This indicated that a gain in precision was achieved by using Landsat- TM in conjunction with the field data. The results illustrated that stratification based on an environmental criterion was an efficient approach as far as the the application of agricultural remote sensing in County Durham is concerned. The stratified approach allowed each stratum to be analysed separately, thereby lessening the reliance on cloud free imagery for the whole county on any given date. Furthermore, the results obtained by this study suggest that it is possibile to link remote sensing data with existing county based information systems on agricultural and land-use.

Långtida markanvändningsförändringar i jordbruket på Ingmarsö

Erlandsson, Rasmus January 2010 (has links)
Traditionellt skötta jordbrukslandskap hyser några av Sveriges mest artrika naturtyper, i huvudsak öppna gräsmarker till vilka en stor del av Sveriges hotade kärlväxter är knutna. Jordbrukets utveckling sedan 1800-talets slut har lett till kraftig minskning av gräsmarker och sämre kvalitet hos de kvarvarande. Skärgårdsjordbruket har små möjligheter till storskalighet och har inte haft samma effektiviseringstryck på sig som jordbruk på fastlandet. Det kan alltså tänkas ha behållit äldre tiders småskalighet – i de fall det fortfarande bedrivs – och därmed stora naturvärden. Studien är en jämförelse mellan jordbrukets utveckling i skärgården och på fastlandet, baserat på GIS-analys av historiska kartdata kompletterat med fältstudier och intervjuer. Undersökningsområdena omfattar Ingmarsö i Stockholms skärgård och Myra, norr om Norrtälje. Arbetet omfattar också en GIS-baserad hävdanalys där gräsmarker klassats utifrån historisk markanvändning. Resultatet är tänkt att vara ett hjälpmedel i restaureringsprojekt genom att ringa in marker med potentiellt höga naturvärden. Reslutatet visar att skärgårdsjordbruket gått tillbaka men behållit sin småskalighet och förblivit aktivt. Till skillnad från det undersökta fastlandsjordbruket som så gott som upphörde innan 1950-talet. Hypotesen att skärgårdsjordbruket skulle vara mindre påverkat av jordbrukets allmäna utveckling bekräftas alltså, men då studien inte bygger på replikat går det inte att dra några generella slutsater. Ett flertal tänkbara förklaringar finns, bland annat skärgårdsbondens bredare försörjningsbas med möjlighet till fiske och intäkter från sommargäster. Hävdanalysen ringar in ett flertal områden som kan vara intressanta föremål för restaurering, men inventeringar krävs för att utvärdera analysmetoden.

Nuosavybės teisių atkūrimas į miško žemę Alytaus apskrityje / Restitution of Forest Land in Alytus County

Jakubauskaitė, Vita 03 June 2009 (has links)
Esminė žemės santykių pertvarka pradėta tik priėmus 1991 m. liepos 25 d. Žemės reformos įstatymą ir 1991 m. rugpjūčio 18 d. Įstatymą “Dėl piliečių nuosavybės teisių į išlikusį nekilnojamąjį turtą atstatymo tvarkos ir sąlygų. Alytaus apskritis yra pati miškingiausia apskritis Lietuvoje t. p. ši teritorija išsiskiria saugomų teritorijų gausa. Miškų ūkio paskirties žemę Alytaus apskrityje 2008 m. sausio 1 d. duomenimis valdė: 42,83 proc. privatūs miškų savininkai, Nacionalinių parkų valdomos žemės nėra, 55,88 proc. visų apskrities miškų valdė miškų urėdijos, 1,29 proc. valstybinės žemės valdė kiti fiziniai ir juridiniai naudotojai. Per 2004 – 2008 m. laikotarpį privačių miškų ūkio paskirties žemės plotas Lietuvoje kasmet didėjo vidutiniškai po 22713 ha, t.y. 90850 ha per 4 metų laikotarpį, Alytaus apskrityje – po 4548 ha, t.y 18191 ha padidėjo privačių miškų. 2008 m. privatūs miškai sudarė atitinkamai 32 proc. Lietuvoje ir 43 proc. Alytaus apskrityje nuo visų miškų. Skirtingas miškų privatizavimo procentas yra dėl to, kad Alytaus apskrityje didesnius plotus užima valstybiniai parkai ir draustiniai, yra santykinai daugiau valstybinės reikšmės miškų. Atsižvelgiant į Žemės reformos įstatymu sudarytas sąlygas miškų privatizavimui, taip pat į galimybes žemės ūkiui netinkamas naudoti žemes apsodinti mišku bei esant svaiminiam apžėlimui (kas dešimt metų vykdant inventorizaciją yra randama apie 50-70 ha savaime apaugusių miškų),iki žemės reformos pabaigos išliks privačių miškų...

Alytus District is the most forested area in Lithuania. Moreover, this territory is famous for its numerous protected areas. The data available on January 1, 2008 show that 42.83 percent of the forest areas belong to private forest owners. Pursuant to this information, the are no any territories owned by the National Parks; 55.88 % and 1.29 % of all forest lands are forestry-owned and belong to other natural persons and legal entities respectively. Within 2004-2008, the area of privately owned forests showed annual increase by 22713 ha or 90850 ha altogether. Within the period of 4 years, Alytus District expanded its territory by 4548 ha annually (or 18191 ha of privately owned forests). In 2008, the privately owned forests accounted for 32 % and 43% of all forests in Lithuania and Alytus District respectively. These forest privatization results differ because Alytus District is mostly covered by state-owned parks and sanctuaries or state forests. With reference to the forest privatization conditions following the Law on Land Reform and the possibilities to use the non-agricultural lands for forests and in the background of self-vegetation of the areas (valuation surveys carried out every 10 years show that there are about 50-70...

ANÁLISE ESPACIAL DA EVOLUÇÃO DA COBERTURA E USO DA TERRA NO DISTRITO DE SANTA FLORA, SANTA MARIA, RS / SPACE ANALYSIS OF THE EVOLUTION OF THE COVERING AND USAGE OF THE EARTH IN DISTRICT OF SANTA FLORA, SANTA MARIA, RS

Pereira, Luciano Volenhaupt 18 February 2008 (has links)
This present work had as objective to spatially analyze the evolution of the covering and usage of the land through the usage of geoprocessing techniques in the district of Santa Flora, Santa Maria, Rio Grande do Sul (RS), in the period of 2000 and 2006. Specifically it was sought to identify, to quantify and to analyze the representative information of the landscape, relating them to the social economical and environmental aspects of the district. In this way, it was used for the accomplishment of the study, Santa Maria's municipal map (1993), the image of the satellite LANDSAT 7 ETM+ (2000) and the image of the satellite CBERS 2 (2006), both of the same time period, implemented by the geoprocessing system SPRING. This system allowed the accomplishment of the classification of the images and in the elaboration of the cartographic elements (cartographic base, hipsometric map, clinographic map and map of the earth usage), associated in parallel to the conference in the field. The classification type was supervised and the images were classified pixel by pixel, and the classifier used was the MAXVER. The thematic classes used for use of land were: forest, farming, field, exposed soil and water. After the stage of image classification, the crossing of the thematic maps was done. With the aid of the LEGAL programming, it was determined the forest evolution, the evolution of the farming field with the following classes: increase, maintenance, decrease, and the areas of permanent preservation in agreement with the current legislation. Among the key findings are referred to the increase area of farming class in 11.008,00 ha between the periods from 2000 to 2006, increasing by more than 100%. Consequently, there was a decline in forest area (6.825,32 ha) in the field (21.291,32 ha) in the period of 2006, due to the expansion of the primary sector, in this case farming. The results enabled know, track and explore the coverage and use of the land through the techniques of geoprocessing, providing subsidies for the different areas. It should be noted that in this study, the agricultural activities are responsible for the changes in coverage and use of the land assigned to socioeconomic policy of the primary sector. / O presente trabalho teve por objetivo analisar espacialmente a evolução da cobertura e uso da terra por meio do uso de técnicas de geoprocessamento no distrito de Santa Flora, Santa Maria, Rio Grande do Sul (RS), no período de 2000 a 2006. Especificamente buscou se identificar, quantificar e analisar as informações representativas da paisagem, relacionando-as aos aspectos socioeconômicos e ambientais do distrito. Desta forma, utilizou-se para a realização deste estudo, o mapa municipal de Santa Maria (1993), a imagem do satélite LANDSAT 7 ETM+ (2000) e a imagem do satélite CBERS 2 (2006), ambos de mesma época, implementados no sistema de geoprocessamento SPRING. Este sistema permitiu a realização da classificação das imagens e na elaboração dos elementos cartográficos (base cartográfica, mapa hipsométrico, mapa clinográfico e mapa de uso da terra), associadas, paralelamente, à conferência no campo. O tipo de classificação foi supervisionada e as imagens foram classificadas pixel a pixel, sendo que o classificador utilizado foi o MAXVER. As classes temáticas utilizadas para uso da terra foram: floresta, lavoura, campo, solo exposto e água. Após a etapa de classificação das imagens, realizou-se o cruzamento dos mapas temáticos. Com o auxílio da programação LEGAL, determinou-se a evolução florestal, a evolução da lavoura com as seguintes classes: aumento, manutenção, diminuição, e as áreas de preservação permanente de acordo com a legislação vigente. Entre os principais resultados destaca-se o aumento da área classe lavoura em 11.008,00 ha entre os períodos de 2000 a 2006, ou seja, acréscimo em mais de 100%. Conseqüentemente, houve a diminuição da área florestal( 6.825,32 ha) e a de campo (21.291,32 ha) no período de 2006, em decorrência da expansão do setor primário, neste caso lavoura. Os resultados obtidos permitiram conhecer, monitorar e explorar a cobertura e uso da terra por meio das técnicas de geoprocessamento, fornecendo subsídios para as diferentes áreas. Salienta-se que neste estudo, as atividades agrícolas são responsáveis pelas mudanças na cobertura e uso da terra atreladas a política socioeconômica do setor primário.
