Find the three most suitable locations for an onshore wind farm in Bristol
The given method uses the simplified version of Baban and Perry. There are plenty of constraints which are identified by Baban and Parry. Most of the thresholds are identified and modified by the values in the study area. The given report presents step by step process in the completion that are required by analyses and presenting the result in cartographical method. The given suggestions on conventions in the instructions can be ignored only when the names of the datasets which are created at each of the analytical steps.
Introduction to ArcGIS
ArcGIS is a set of instructions of the applications. That is there are a number of programs that are added together to make up the entire GIS functionality. This is similar to the way Microsoft Office has so many component programs such as Excel, PowerPoint and Word. ArcMap has got similar tools and applications as that of PowerPoint as it is the application for looking at the GIS data graphically. The application used for data creation and management is called Arc Catalog. Arc Catalog is very similar to the Windows Explorer. It is just that it has data formats that can be used in ArcGIS that may be in a variety of formats and tabular datasets. In every applications there exist some toolboxes that can be used to access the appropriate functions for each of the applications.
Managing spatial data
The question now is how to manage the spatial data using the ArcCatalog. The first thing that is to be done is to create a new folder. The folder made is in the D: drive of the computer machine you are working on and is identifiable as containing the work. To manage your work better one can use initials followed by underscore and GIS postfix. Next the thing that comes is that use the move folder app present on the desktop to copy the folder Base data from S:/FET/SUPPORT/MAPS/WINDFARMS to the folder the user creates at first. The next step inquires the usage of the windows explorer and open the new folder just created and save the base datasets and answer the questions as given. After that one needs to open ArcCatalog and navigate to the same folder made earlier. If the folder you already created goes missing or is not found click on the icon that looks like a black cross with a yellow folder icon. The next window takes you to the interested folder you would like to go to. The basic difference between the two views is that the ArcCatalog manages and presents the component files of the spatial data source as a single spatial data set. As because of its intelligence the handling of the spatial data always use the ArcCatalog to manage the spatial data sets. At the end of each practical one must use the move folder app to move the folder working on to the H:\ drive which is supposed to be a secure network space which is backed up regularly. At the start of the second session we need to move it back and continue the working. It is very much sensible to keep a up to date copy of the GIS folder on a USB removable drive. It is not mandatory to save the work that has been done in the ArcCatalog. Since it is mostly about data management and structures, the changes made are automatically saved. One however needs to be familiar with the terminology of the hierarchy of vector data types works in the geodatabase format. The raster datasets can be stored in the geodatabase and can be represented by regular grid icons.
The Data Dictionary
To take care of the table we need to select a dataset in the ArcCatalog in the area of the heading catalog. The next that is to done is to select the preview tab in the large area to the right of where the dataset is selected. After that one needs to include all the data sets. The next session completes the table so that the user is familiar with the familiar with the official data before you start the analytical process.
Introduction to Arc map Interface
There are plenty that can be docked along the side of the interface. They are active as you right click in the grey area at the top of the interface or by selecting the toolbar to activate or deactivate. Other than that there are for more common ArcGIS toolbars annotate them in the same way as that of before preceding to the exercise.
Exploring the Geodatabase
In conjunction to the dictionary data task, this part is designed to enable and helps you to get through the spatial and attribute on has with them to complete the project. Thus is done by clicking on the Add data button and then navigating to the working folder. The geodatabase are used to feature classes to add up to the ArcMap project as layers.
ArcGIS and Geoprocessing
To create the areas that are constrain the developments based on the information we need to perform spatial analyses and implement buffers. This is generally based on the Baban and Parry method. There are plenty of other constraints that are identified by baban and parry but are not included in the analysis. Most of the thresholds are modified to values appropriate to the study area. This session generally has the following learning objectives:
- To perform a buffer process
- To perform a union process
- To perform a dissolve process
- To plan a geoprocessing application
- To introduce you to the Arc Toolbox
- To perform a slope analysis of raster data
- To perform an aspect analysis of raster data
- To use the raster calculator
Completing a geoprocessing application is generally about GIS usually involving more than the use of the single, specific geo tools. It is required that they use the orchestrated implementation of a series of processes. This process might be necessary any number of times as possible until and unless the final result is achieved. To complete the entire task one needs to consider the development within the defined area. And which requires the development beyond the definition area.
Wind farm development
This session is all about combining the previous two results in order to identify the areas which are suitable for the farm development. The datasets which has been developed so far are combined exclusion zones, inclusion area and the topographical suitable areas. What next is to be done is to combine the topographically suitable areas and the inclusion areas with suitability layers and then remove this layers that are within the exclusion zone. The next bit of analyses that needs to be taken care of is that to undertake the visibility analysis used to assess the visual impact of the three potential farm sites. Once the analysis is taken care of they need to present the process and the product of the analysis that is to be completed in series of maps. The booklet that needs to be present are the basic instruction, create, the maps that is needed to be produced for coursework.
Producing the Maps for Report
This section is used upon and is as a guide to help you plan the maps. This section of the maps can be used to show the process of the analysis. The first thing that needs to be taken care of is to establish the mapping needs. This is done when you plan ahead and decide on how many maps you are supposed to make. The purpose of the map, suitable titles, list of datasets, overall style and the fonts you are going to use. Once these are decide you can go on to create and establish a basic style from them. Then one needs to think on about the individual maps and answer few questions on how you intend to produce before starting. Then the creating part starts in ArcMap. Previously you might have been looking a layout in the switch mode which is now in the form of Layout view. We already know how to symbolize features in the feature class with the use of unique values from the attributes. While compiling your final maps one needs to group features and assign the symbols in the group. To add map furniture one needs to add the layout from the insert menu item. The legend wizard window ha two lists. One needs to map layers in the view list, the second has the selection that can be displayed in the legend. Set border and background for your legend in the windows. The next window manages the spacing between the legend and the items and again accepts the defaults. Type a suitable title for the map that suits your map style. A well balanced design combine the intention, symbology, content map furniture and considerations. One should always remember that you are creating a map series and the conventions you adopt can be consistent.
