4. Types of derelict areas - categories to be recorded are :- 
a) Spoil Heaps 
b) Excavations and Pits including working quarries 
c) Military and other Service derelict areas 
d) Disused rallway land 
e) Disused waterways (infilled or 100% vegetative cover) 
f) Disused sewage works and installations 
g) Disused sewage farms 
h) Demolition areas 
1) Scrap yards a) vehicle 
b) miscel laneous 
J) Allotments 
k) Neglected waste ground - this is particularly important in urban areas 
1) Disused dockland 
m) Tipping sites - sites were tipping is evident 
n) Others - areas such as disused roads which may be classified as dereiict 
5. State of use of each site 
a) In use - Tipping sites (4m) and scrapyards (4i) are to be regarded as "in use" if refuse or 
other material Is seen to be present. The last previous use will be recorded if this Is recognisible 
on the photographs, eg. a quarry now being used as a tipping site. 
b) A distinction wil! be made to show whether the site is used or disused in categories a, b, c 
and je 
6» Water on slte - streams, drains, rivers and canals are not to be considered. 
1) Water present 
2) Water not present 
7. Buildings on sites 
1) Yes 
2) No 
8. Tipping on sites 
1) Yes 
2) No 
9 Surrounding land use - at some sites more than one "land use" may be present on adjacent land. 
Categories are to be classified on a 5 point scale indicating order of areal extent. 
a) Industrial 
b) Residential 
c) Urban centres, shops and commercial installations 
d) Agricultural 
e) Parkland (urban only) 
f) Other - this category can be further subdivided 
o 
° 
Vegetation type - classifications to be :- 
a) Trees 
b) Shrubs 
c) Grass 
11. Vegetation cover - the total degree of vegetation cover is to be expressed as :- 
a) «102 cover 
b) 10% to 50% cover 
c) >50% cover 
INTERPRETAT ION 
Two year old black and white, panchromatic, 1/5000 scale aerial photography was available for the 
sample area. After some interpretation expertise had been attained, an air photo survey was carried 
out using these photographs to produce a map showing the extent and distribution of derelict land 
for 1977. 
Training in Interpretation was done by establishing an air photo key, "a device designed to aid the 
Interpreter in the rapid and accurate identification of objects from the study of aerial 
photographs"2. 
An air photo key Is normally produced by checking the photo identified objects with ground observed 
data. This is done for a sample area within the total area under study. For this survey, time 
limitations required that the training process be speeded up; by studying aerial photographs of a
