# We measure the coast
and draw what is
actually there.

A survey and cartography office in Tromsø. Six people, two boats, one plotter that has never once jammed on a Friday.

- 114 sheets published
- 28 years above the Arctic Circle
- 6 cartographers and surveyors
- 2 survey vessels

Kvaløya, north coast. Flown 04.06.2025, 1,200 m AGL.

## What we do, in four parts

A

### Control and levelling

Primary and secondary control networks, precise levelling, deformation monitoring on dams and quays. Adjusted in-house, reported with the residuals attached.

±2 mm / km

B

### Airborne and terrestrial lidar

Point clouds at 40 to 400 points per square metre, classified and delivered as LAZ with a terrain model on top. We fly our own missions between March and October.

400 pt/m²

C

### Hydrographic survey

Multibeam bathymetry to IHO Special Order in sheltered water, Order 1a offshore. Tide-reduced against our own gauges, not the nearest port.

IHO S-44

D

### Cartographic production

Everything above turned into a sheet somebody can fold in a wind. Colour, hierarchy and generalisation are decided by a cartographer, not a default style.

6 colours

## Published sheets

Sold at the office and by six chandlers along the coast. Every sheet carries its survey date on the reverse; we do not reprint without resurveying.

N-097 | Tromsøysundet approaches | 1:10 000 | ETRS89 / UTM 33N | 7th | 2025
N-091 | Senja, western fjords | 1:50 000 | ETRS89 / UTM 33N | 3rd | 2024
N-083 | Balsfjord, valley floor | 1:25 000 | ETRS89 / UTM 34N | 5th | 2024
N-076 | Ringvassøya interior | 1:50 000 | ETRS89 / UTM 34N | 2nd | 2023

## Terrain, honestly generalised

A contour is an opinion about where a slope stops being one slope. We publish ours at three generalisation levels and say which one you are looking at.

Our terrain models come out of lidar we flew ourselves, so we know what the vegetation was doing that week and how much of the ground we actually saw through it.

Where the point cloud is thin, the sheet says so. There is a small grey tint on the reverse index for every square kilometre we would not stake a boat on.

## How a sheet is coloured

Three tints, printed in that order. Every sheet in the catalogue uses the same three and nothing else.

01

### Water and depth

Flat tint under everything. Two steps only: charted depth and the rest. A third step would imply a survey we have not done.

02

### Relief and slope

Hillshade from our own lidar, never from a public model. Where the cloud is thin the tint stops and the sheet says so.

03

### Culture and route

The only layer allowed the accent blue. Roads, tracks, cairns, and the two ferries that still run in winter.

## Instruments on the shelf

Everything is owned, calibrated annually, and taken to the field by the person who booked it.

## Asked at the counter

Why is my house not on the sheet?
  Buildings under twelve square metres are omitted at 1:25 000 and everything is omitted at 1:50 000. It is on the survey; it is not on the print.
Can I have the data instead of the sheet?
  Yes, as LAZ or GeoPackage, at the same price. We will ask what you intend to do with it, not to refuse you but because the answer changes which product is right.
Do you correct errors?
  Every reported error is checked within a fortnight and the sheet is reissued at the next printing. The errata list is on the counter, on paper, going back to 1998.
Why no digital hillshade on the 1:50 000?
  Because at that scale it hides the contours, which are the thing you actually navigate by.
