Remember to explain what type of metadata you will create (i.e. is it fordiscovery or is it for detailed assessment of features) [30%]3.

In this assignment you are going to explore the process of capturing a vector spatialdata set that meets the data specification for a particular application. The data setyou are going to create is a historical land cover map (see definition for land coverbelow) of an urban area. In terms of an application you can assume you are workingfor an environmental consultancy who have been asked to map the assigned areawith a review to regeneration. You will be supplied with a geometrically correctedRGB aerial photograph of the urban area, which covers part of Salford, UK, and youare required to create a vector-based data set from that aerial photograph for use inArcGIS (or an equivalent GIS package). The deliverable from this process will be awritten report outlining the process you have gone through to create the data set; a properly scaled image of the map you have created; associated metadata; and anevaluation of the approach you have taken.Definition of Land Cover:“Land cover refers to the physical and biological cover over the surface of the Earth,including water, vegetation, bare soil or rock” (Sultana and Powell, 2010: 1726).Added to this basic definition you could also include manmade surface types, suchas concrete and tarmac. The key thing with land cover is that you do not try tointerpret a use for the surface types identified.Reference: Sultana, S. and Powell, W.T., 2010. Land Use. In Warf, G., editor,Encyclopaedia of Geography. Sage Reference: Los Angeles, London, New Delhi,Singapore, Washington D.C. pp. 1726 – 1732.Aerial PhotographyYou will each be provided with an RGB aerial photo of part of Salford. Thisphotography is copyrighted and so should not be used for any other purpose thanthis assignment.The aerial photo is panchromatic and has a spatial resolution of 25cm, and datesfrom the early 2000s.Your report should comprise the following elements:1. Preparation – Consider the function of a land cover map and identify whatfeatures you will include in your map and how you might represent thosefeatures (i.e. as points, lines or polygons). Examine the aerial photographand identify issues with it as a data source for a land cover map). [30%]2. Data capture strategy – Identification and justification of the approach tobe taken, data standards to be used (i.e. metadata standards) and how anylimitations with the aerial photograph as a data source will be addressed.Remember to explain what type of metadata you will create (i.e. is it fordiscovery or is it for detailed assessment of features) [30%]3. Data capture – this section should include a copy of your map embeddedas an image in your report, and a copy of the accompanying metadata youhave created. [30%]4. Evaluation – including a review of your map against other similar mapproducts for the same area (if any are available), and a critical discussionabout what might be the ideal data set for this application.
