from point sources, which refer to the large number of plants, <strong>for</strong> which the<br />

fuel consumption is known at plant level but emissions are calculated due to<br />

standard emission factors.<br />

(FOFSBM NFUIPEPMPHZ<br />

The distribution of emissions in the Danish emission inventory is carried out<br />

in databases and in a ge<strong>og</strong>raphical in<strong>for</strong>mation system GIS.<br />

The methodol<strong>og</strong>y applied in the part of the distribution carried out in GIS is<br />

shortly described in this chapter. The description is made <strong>for</strong> the Industrial<br />

Processes sector as case, as this distribution is rather simple.<br />

The emission inventory <strong>for</strong> Industrial Processes covers both point sources<br />

and area sources. Emissions from point sources are allocated to the coordinates<br />

<strong>for</strong> the individual plants included in the Danish inventory system and<br />

are not relevant in relation to the GIS procedure. Emissions from area<br />

sources are calculated from production statistics and the resulting emissions<br />

are national totals as allocation of the sources (industrial plants) is not possible<br />

with the available data. Instead a proxy <strong>for</strong> the distribution is applied, in<br />

this case the location of industrial areas as given in the national top<strong>og</strong>raphic<br />

map KORT10 by the National Survey and Cadastre (Figure 2.1). The map of<br />

industrial areas is not reflecting differences in the location <strong>for</strong> different industries,<br />

but only holds industrial buildings (referred to as the industrial<br />

area as the buildings are treated as areas rather than units). The map is a<br />

shape file and the industrial areas are polygons.<br />

As SPREAD gives emissions on 1x1 km, the map of industrial areas must be<br />

combined with the Danish 1x1 km Grid Net. The grid is an orth<strong>og</strong>onal coordinate<br />

system and the cells are defined and named by their lower left corner<br />

coordinates. The grid net map is a shape file and the grid cells are polygons<br />

(Figure 9.2).
