Spatial Modelling: Wind Energy

STUDENT amply NAME: FIONA BARRIE

1. What type of variable is the wind speed data? [1 mark]
continuous

2. How much area of the Isle of Wight has wind speeds undecided of powering a 45 m wind turbine to meet the ships companys capability requirements? [3 marks]
174.1km squared

3. a. How much republic classified as urban falls within those areas suited for wind energy production? [3 marks]
21.2km squared
b. Which IDRISI manipulation operators did you use to calculate this value (list them in logical order with any parameters/operator options used)? (450 characters) [5 marks]
Select: G.I.S compend - databasequery - OVERLAY. Choose first range: windspeed_over_69, second realise: urban. yield cipher type urban_windspeedover69, select first *second. Then while away G.I.S analysis - database query - EXTRACT. In feature definition image choose Urban. Image to be processed will be: Urban_Windspeedover69. Select Total sum, and tabular. Answer given, turn into km.

4.



Given that (i) SSSIs deficiency to be preserved, (ii) woodlands and surrounding areas are not suitable sites, (iii) turbines command to be located at least 1 km away from urban areas, and (iv) wind speeds need to be qualified of generating sufficient energy:
a. What total area of land is suitable for constructing wind turbines? [3 marks]
25.9km squared
b. Briefly outline your methodology for calculating this land total; provide justification for decisions regarding operators and parameters you have used. Include a flowchart to illustrate the cartographic process* (1000 characters) [8 marks]
G.IS analysis-Distance- BUFFER. In device characteristic Image: Urban, Buffer Width: 1000, think of Target Area in Output Image: 2, Value for buffer zone in output image: 0,Value for non buffer zone in output image: 1, Output image: Urbanarea_Suitable. Buffer map created. twin with woodland, with Buffer width: 500....If you want to get a full essay, order it on our website: Ordercustompaper.com
