Copyright of maps in Denmark
Maps published in Denmark by the government since early 1800s generally are subject to a special copyright that never expires. For this reason, tracing from maps that carry any marking such as Generalstabens topografiske Afdeling, Kongelige Søkort-Arkiv, Geodætisk Institut etc. should be avoided even if they appear to be out of copyright by the normal rules.

Tasks
Administrative divisions
Denmark/Administrative divisions has more details including guidelines on how the various administrative divisions can be mapped.
The goal of these tasks is to map administrative boundaries and the closely related parish boundaries as far back as these can be documented.
| Task | Status |
|---|---|
| Clean up chronologies around Kingdom of Denmark vs Denmark proper | To Do |
| Region boundaries (2007-) | Mapped but missing source |
| Amt boundaries (1970-2006) | Mapped but from low resolution source |
| Amt boundaries (1793-1970) | In progress: Southern Jutland counties missing, precise start dates missing |
| Amt boundaries (1662-1793) | Not started, need sources |
| Herred boundaries | In progress: Southern Jutland missing |
| Sognedistrikt boundaries (1803-1841) | Not started: need sources for which parishes organized into districts |
| Sognekommune boundaries (1842-1970) | Complete: Københavns Amt, Frederiksborg Amt |
| Købstad boundaries (?-1970) | Some mapped incidentally |
| Kommune boundaries (1970-2006) | Not started, need unrestricted sources |
| Kommune boundaries (2007-) | Not started, need unrestricted sources |
| Ejerlav boundaries (16XX?-) | Not started, some mapped incidentally |
| Sogne boundaries (?-) | Complete: Københavns Amt, Frederiksborg Amt. In progress: Præstø Amt |
Regional details from Trap 2nd ed. maps
The goal of this task is to trace regional details from Trap 2nd ed. regional (county) maps.
- Primary road network (thick black or white lines)
- Hamlets, villages and towns as nodes (settlements)
- Larger lakes and woods
These are details that have enough clarity at the scale of the regional maps. Smaller features like minor roads, streams, and smaller woods may be too difficult to trace accurately from these maps.
| Task | Status |
|---|---|
| Primary road network | Complete: Frederiksborg, København, Præstø |
| Settlements | Complete: Frederiksborg, København. In progress: Præstø |
| Lakes, woods | Complete: Frederiksborg, København |
Local details for market towns from Trap 3rd ed. maps
The goal of this task is to trace local details from Trap 3rd ed. market town (købstad) maps.
- Street network: Trace the street network from around 1900 when the maps were created
- Buildings and amenities: Add particular buildings and amenities marked on the maps, such as churches, city halls, hotels, etc.
| Task | Status |
|---|---|
| Major street network | In progress: Mostly complete except the last half of the volume 3 maps |
| Full street network | Not started |
| Significant structures and amenities | Not started |

Trap Danmark
J.P. Trap. Statistisk Topografisk Beskrivelse af Kongeriget Danmark (see also wikipedia:da:Wikipedia:WikiProjekt_Trap_Danmark and Projekt Runeberg)
The first three editions are considered out of copyright.[1] In addition, none of the included maps appear to be based or include any data from government maps that would be covered by the special perpetual copyright of maps in Denmark. For example, the Royal Library of Denmark confirms that maps like [1] from Trap, 2nd ed. are out of copyright.

Historical aerial imagery
Some of these seem like they are based on photos which might not be covered by copyright anymore since it would be expired for photos in Denmark taken before 1970 that don't have "artistic merit" (værkshøjde). Nevertheless, it seems that the private companies owning the aerial imagery still assert that they have exclusive rights.
- 1944: LW1944 Partial coverage.
- 1945: Flyfoto 1945 All of Denmark covered in the first set of aerial imagery of the whole country.
