When is a sketch map better than a copy of an Ordnance Survey extract?

When the point being made would be lost in the detail. A published map shows everything at once, so a specific pattern - the arrangement of sampling sites, the extent of one land use, the sequence of landforms along a coast - competes with hundreds of other features. A sketch map strips those out and can exaggerate what matters, and it can carry annotations written directly onto it. The published map remains better where accurate position, precise distance or full context is needed, which is why the two are often used together.

What are the commonest mistakes made in drawing sketch maps?

Leaving off the conventions, especially the north arrow and any indication of scale; copying too much detail so the map is cluttered and the point is lost; labelling features without annotating them; drawing features so far out of proportion or position that the map misrepresents the site; and failing to give a title that says where the area is. A sketch map with no key to its symbols or shading is also unreadable.

How would you use a sketch map to show the location of a study area?

Draw it at two scales if necessary: an inset showing the region or country with the study area marked, and a main sketch showing the immediate area. On the main sketch show the coastline, river or main roads that fix the position, name the nearest settlements, mark the study sites, and add distances and a north arrow so the reader can judge how far apart the sites are. Annotate the features that explain why the site was chosen, such as the meander bend investigated or the boundary between two land use zones.

Questions from this subtopic

Each one with the model answer underneath.

1
What is a sketch map, and what is it for?
Model answer
A sketch map is a simplified, hand-drawn map that shows only the features relevant to the point being made, drawn roughly to scale rather than surveyed. It is used to show the location of a study area, to summarise a distribution or a landform assemblage, or to record what was observed at a site. Its purpose is communication: by omitting everything irrelevant, it makes one geographical point clearly, which a full topographic map cannot do.
2
What is the difference between a label and an annotation?
Model answer
A label simply names a feature - sea wall, meander, terraced housing. An annotation names it and then says something geographical about it: sea wall, undercut at the base, showing that wave attack continues despite the defence, or meander with an undercut outer bank where flow velocity is greatest. Labels identify; annotations explain, interpret or link the feature to a process, and it is the annotation that earns credit.
3
What should a fieldwork sketch map of a study site include?
Model answer
A title stating what and where it shows, a north arrow, an indication of scale, and a frame. Within the frame it should show the outline of the main features - coastline or river channel, roads, buildings, land use boundaries - the position of each sampling site clearly marked and numbered, and annotations explaining the significance of what is shown. Grid references for the corners or for key points let the reader relate the sketch to a real map.
4
When is a sketch map better than a copy of an Ordnance Survey extract?
Model answer
When the point being made would be lost in the detail. A published map shows everything at once, so a specific pattern - the arrangement of sampling sites, the extent of one land use, the sequence of landforms along a coast - competes with hundreds of other features. A sketch map strips those out and can exaggerate what matters, and it can carry annotations written directly onto it. The published map remains better where accurate position, precise distance or full context is needed, which is why the two are often used together.
