ENVS200: Creating a Final Map Poster

In Year 3 you will need to produce a computer-drawn final map as part of your independent dissertation project. This exercise is to help you learn and practise the skills needed.

You should use GIS software (ArcGIS/QGIS) to create the map itself, and a graphics program like Corel Draw to draw the sections, GVS and key and to put the poster together. The University of Liverpool provides Corel Draw as its preferred graphics drawing package.

For this exercise, you are required to complete a final map that will fit on one sheet of A4, based on a field map of Melmerby in the Lake District. The map should be clearly derived from the field map.

The final map poster must include:

1. A title that indicates where the mapped area is located.

2. The name of the author and the date mapping was completed and the date the final map was published.

3. Location map(s) of the area (with scale, North, Longitude, Latitude).

• These should be purpose drawn, not just lifted from Multimap, Encarta, Google.

4. Final solid geology map(s) at appropriate scale(s), which may be different to the scale mapped in the field.

• Formations should be indicated by both colour and letters so that the map is usable in black and white (e.g. if photocopied).

• Each formation should display a unique colour and letter/number code.

• Boundaries should use standard representation of solid line for observed boundary, dashed line for inferred boundary and pecked line for drift boundary.

• The map(s) should show the location of drift deposits, but these should be subordinate to the solid geology. The boundaries of drift deposits should be marked by a pecked line. Solid geology should normally be coloured through the drift deposits and solid boundaries marked by a dashed line. Drift may be filled with a transparent colour [white with ~90+% transparency] to allow solid geology and drift to be seen simultaneously.

• The map(s) should contain as much representative data (bedding etc) as is necessary to define the structure of the area. In an area of structural complexity it may be appropriate to transfer most or all of the data from the field maps. In simple areas, where most readings are similar, fewer data need be transferred. Make sure structural data are legible: symbols should be at least 5 mm in length and dip/ plunge numbers should be at least 8pt on the final printed map. Do not include values for the strike.

• The map(s) can include salient annotations where appropriate.

• The map(s) should not include geomorphological information (breaks of slope etc)

• The map(s) should not include locality numbers.

• The map(s) must include a scale bar, North arrow and an indication of magnetic declination.

• The map(s) must be located with respect to national/GPS ordnance survey grids and/or latitude and longitude.

• Maps should be computer-drawn and include a topographic base map. If you choose to create your map in CorelDraw, you will need to scan in the base map and trace relevant features (coastlines, roads, contours etc) into a layer in CorelDraw.

5. At least one cross section at the same scale as the map with no vertical exaggeration. The section must be properly located on the map. If the section is not vertical the orientation should be justified (e.g. profile-plane section). Geology should be extrapolated below sea level and above ground. Use form lines to illustrate bedding where appropriate.

6. At least one generalised vertical section [GVS], to scale and with full chronostratigraphic subdivisions (i.e. with proper names like Ordovician, Arenig etc) as well as lithostratigraphic divisions. See the GVS construction primer for advice.

7. The lithological unit key should be incorporated into the GVS, including superficial deposits, unless this is impossible. Units shown in the GVS do not need to be repeated in another key. Units that cannot be placed in the GVS, such as igneous intrusions, should be included in a separate lithological key. Units on the map should be lithostratigraphic subdivisions unless this is impossible. Each formation should have its own colour and letter code which should be identical across map, cross section and GVS.

8. Make sure all symbols, including line symbols (boundaries, faults etc) are listed in the key.
