Billeddokumentationen viser skadesomfanget.

Because Danish, like German, very often forms compound nouns by writing the parts together.

So:

• billeddokumentationen = billed
  • dokumentation
    • -en
• skadesomfanget = skade
  • s
    • omfang
      • -et

In English, we often use several words, such as photo documentation or extent of damage. In Danish, these ideas are commonly packed into one noun.

This is completely normal Danish spelling, not an unusual or technical feature.

The ending -en is the definite singular article for many common-gender nouns.

So:

• en billeddokumentation = a photo documentation / photographic documentation
• billeddokumentationen = the photo documentation

In Danish, the word for the is often attached to the end of the noun instead of being a separate word.

The ending -et is the definite singular article for many neuter nouns.

So:

• et omfang = an extent / a scope
• omfanget = the extent / the scope

In the compound skadesomfanget, the main noun is omfang, so the whole word takes the definite ending based on omfang:

• skadesomfang = damage extent / extent of damage
• skadesomfanget = the extent of the damage

Because Danish usually expresses definiteness by adding it to the noun itself.

Compare:

• en dokumentation = a documentation
• dokumentationen = the documentation

and

• et omfang = an extent
• omfanget = the extent

So instead of saying something like the billeddokumentation, Danish normally says billeddokumentationen.

That is why the sentence has no separate word corresponding to English the.

That s is a linking element used in many Danish compounds.

• skade = damage
• omfang = extent
• skadesomfang = literally damage-extent, meaning extent of damage

The s does not function here like an English plural -s, and it is not a normal possessive apostrophe form either. It is simply a common way of connecting parts of a compound noun in Danish.

You will see this quite often in compounds. Unfortunately, it is not always fully predictable, so learners usually get used to it word by word.

In compounds, Danish often uses a stem form of the first noun rather than the full standalone form.

The independent noun is:

• et billede = a picture

But in compounds, it often becomes billed-:

• billedbog = picture book
• billedtekst = caption
• billeddokumentation = photo documentation

So billed- is a normal combining form meaning picture-/image-/photo-.

Also, compound nouns are written as one word, so billede dokumentation would not be standard spelling.

Viser is the present tense of the verb at vise = to show.

So:

• at vise = to show
• viser = shows / is showing

In Danish, the present tense is very often formed by adding -r to the infinitive stem:

• at komme → kommer
• at læse → læser
• at vise → viser

So Billeddokumentationen viser skadesomfanget means The photo documentation shows the extent of the damage.

No, this is a very straightforward main-clause word order:

• Billeddokumentationen = subject
• viser = verb
• skadesomfanget = object

So it follows the basic pattern:

Subject + Verb + Object

That makes this sentence a good example of standard Danish word order in a simple statement.

It is singular.

The head noun is omfang:

• et omfang = an extent
• omfanget = the extent

So skadesomfanget means the extent of the damage, not the extents.

Even though English might sometimes talk about damages in legal or financial contexts, here Danish uses a singular compound noun referring to the overall scope or extent of the damage.

Grammatically, billeddokumentation without -en is the indefinite form, so it would mean something more like photo documentation in a general sense, not the photo documentation.

Compare:

• Billeddokumentation viser skadesomfanget = Photo documentation shows the extent of the damage / Photographic documentation shows...
• Billeddokumentationen viser skadesomfanget = The photo documentation shows the extent of the damage

The version with -en sounds more like you are referring to a specific set of images or a specific documentation already known in the context.

Yes, shows is the most natural translation in this sentence.

The verb at vise can have several related meanings, such as:

• show
• display
• point out
• indicate

But in this context, where documentation makes something clear, shows is the most idiomatic English choice:

• Billeddokumentationen viser skadesomfanget.
• The photo documentation shows the extent of the damage.

You could sometimes also translate it as documents or demonstrates, depending on context, but shows is the plain, direct equivalent.
