BSC Review

P3.2.2. (third paragraph)

Comment made at second sentence: I assume it is intentional to repeat the next three sentences exactly as before.

MT: It comes straight from CM, but I admit it does look pretty weird to have these 3 sentences repeated under both type (a) and type (b). Should we revise it? How about:

Properties and typical characteristics. The individual sheets in a special or thematic map series may be used independently, and the concept of area is still quite important as a unifying factor. The primary characteristic is, however, the display of subject or thematic information. Map series of this type are normally either:

(a) a group of maps each of the same area but displaying various themes or aspects of the same theme, e.g., geology, soils, monthly rainfall totals for the year, and irrigation potential within a country; or

(b) a group of maps devoted to a common theme but not of the same area, e.g., maps indicating irrigation potential within a country.

Sheets of subtype (a) are generally of uniform size, scale, and projection, etc., because it is most economical to create them on a common base and superimpose the various subjects on that base. In many cases the sheets are published at about the same time and may not be available separately. As they are often the result of a specific project, the sheets are unlikely to undergo subsequent revision, but if revision does take place, it will almost certainly be applied to all sheets at the same time. The entire special series will almost invariably be the work of one publisher who is likely to indicate the relationship between sheets by means of the designation, the sheet identification, or both.

East Africa 1:4,000,000

(Comment: Sheets cover the mineral resources, forest and game resources, vegetation, geology, soils, and physical features, each of the same area)

Sheets of subtype (b) may be at different scales and different projections and may show non-contiguous areas, though usually within a defined geographic entity. In many cases the sheets are published at about the same time and may not be available separately. As they are often the result of a specific project, the sheets are unlikely to undergo subsequent revision, but if revision does take place, it will most certainly be applied to all sheets at the same time. The entire special map series will almost invariably be the work of one publisher who is likely to indicate the relationship between sheets by means of the designation, the sheet identification, or both.

Emergency Measures Organization, urban analysis series : [Canada]

(Comment: Includes Vancouver (32 sheets) and Toronto (32 sheets of each E & W); sheets are devoted to a common theme but are not of the same area)

With both subtypes, the sheets are usually published at about the same time and may not be available separately. As they are often the result of a specific project, the sheets are unlikely to undergo subsequent revision, but if revision does take place, it will most certainly be applied to all sheets at the same time. The entire special map series will almost invariably be the work of one publisher who is likely to indicate the relationship between sheets by means of the designation, the sheet identification, or both.

TF: I like this revision. 1/6/16 

RB: Yes, that's better. 1/6/16 

LSC: This is much clearer.  I would suggest including blank lines before and after the examples and comments.  1/16/2016

MT: Done (but changed "usually" to "often" since that seemed a closer match to "in many cases"). Don't worry, there are blank lines in the document, I just didn't include them here to save space. 1/6/15
