Taking orthophotos on Kvaløya May 15 2023

That’s me, nine days ago, near a parking place by the lake Finnvikvatnet on the island Kvaløya.

I just got a drone from the Norwegian Polar Institute, a DJI Mavic Pro 2. Since it is forbidden to fly a drone in Tromsø (too near to the airport) I chose a place on Kvaløya to check out the drone and practise a bit.

What you may expect from drone flying is photos like this:

What I actually did that day was taking a bunch of photos like these:

Back at home let the computer do some heavy work. That’s the result:

What I wanted to achieve is creating a so-called orthophoto. That is a stitched image that also contains geographical information. You need quite a lot of photos to get good results. In the map above it is only 9 photos and 11 photos in two distinct groups.

I used two softwares: First OpenDroneMap to create the orthophoto and then QGIS, an open source Geographic Information System, to present the orthophoto in a geographical context.

This afternoon I took a trip to Kvaløya again, this time to the way to Sommarøya and stopped by the lake Kattfjordvatnet. Here I pulled up the drone to an altitude of 80 metres and tried to navigate a rectangular zig-zag pattern with a lot of overlapping between the images. Beside of the fact, that the images are underexposed (and I was too lazy to correct them) I’m quite content with the result. The first image is an oblique shot, the second image is an orthophoto calculated from about 80 images and then placed into QGIS.

Plan for the next two weeks: getting more practise!

Winterly Kvaløya Apr 23 2023

What a misjudgement! Since it was warm the last weeks I didn’t expect so much winter in Tromsø and around. It was a mistake not to take skis or/and snowshoes with me, when I visited the neighboring island Kvaløya today. And here everything was still snowy. Very snowy. So for example the tombstones on the graveyard in Henrikvik. Or a fence nearby, where only the edge looked out of the snow.

Snowed in tombstones in Henrikvik, Kvaløya

How many tombstone there are around? Hard to say. Some of the larger ones were quite visible while other parts of the graveyard were just a white sheet of snow. I’ll have to check in summer.

Although the temperatures were sub-zero the road by the coast was wet and free of snow. This changed when I turned into the road to Sommerøya, the summer island. Although the road is just 150 meters above sea level it was snow covered. During the snow showers it was hard to see the roadside and I slowed down a lot for every car that came my way.

Some other cars parked at the different parking places. Two skiers just started a tour. But I could hardly spot any fresh ski tracks and even some of the avalanche transceiver test station were quite snowed in. No wonder because parts of the lake Kattfjordvatnet are already open and the ice is not safe anymore.

On the other side of the water: a group of trees in the fresh, white snow. Not a single ski track could be seen. At least here ski season seems to be over.

On the other side walking through the snow is not the best idea neither, especially when there are deep, snow-covered ditches …

Skitour on the Austeråsfjellet Mar 26 2023

Slowly I’m gaining height with my fjellski. It is sunny and almost windless. Round -6 °C. I seem to be alone. I start traversing a slope while continuing gaining height. I’m nervous. I’m not a downhill skier and every metre I ski up I have to ski down again somewhere.

Mission accomplished: I’m above the tree line. Above me the blue ski, below the white snow. And, while I go further I get another blue: The sea.

When I look back I can see the whole island Tromsøya. Somewhere over there in the south, hidden by the wooded hills is my small rented apartment.

I didn’t plan a route for today. I just wanted to be out enjoying the winter. But when a heap of stones marks a top and it’s easy to reach I have to ski there. Mountain summit 1: Kraknesaksla (ca.335 m). With a nice view into the sound Grøtsundet.

According to the map there are some lakes a bit down. The lakes are invisible. There is only snow. What I can see are the buildings. One small cabin and a wee, tiny shed with a wind turbine. The cabin is closed and I cannot see any sign. Probably it’s private.

I continue my ski trip. I have reached a vidda – a plateau.

Now I start to see other people. A single skier, a group of three going uphills, a skier with a dog in the distance. Most locals love to be outdoors but perhaps not as early as I.

I decide to ski to a mountain top I found on my map app Norgeskart. It’s called Jerremaš (467 m) and is a kilometre away. On the way there I see that the group of three heads into the same direction while two others are already returning. Seems to be a popular place.

And it is. I’m not alone. Several other skiers are sitting there, enjoying the sun, talking Norwegian. Almost all of them are 65+.

I look at the 360 degree panorama. There are snowy mountain chains everywhere, the sound Kvalsundet, the island Ringvassøya and somewhere in the northwest the Norwegian Sea.

How shall I continue the tour? Skiing downhills and letting the others watch how I fall face first into the snow? As I mentioned before, I’m not a downhill skier. The others are probably all former Olympic athletes. I decide to take a small detour …

I start to ski down. To my surprise the hills are gentle and the snow is soft and uniform. I manage to ski downhill the broad, snowy slopes and I’m enjoying it. Sometimes I even think, it is too slow.

Much faster than expected I leave the vidda behind. I pass the first trees and see more and more tracks – and skiers. Many of them are skiing on the prepared ski trail that cuts through the valley like a German Autobahn. Others just sit on a mat in the snow taking a break.

A hole in the snow triggers my curiosity. I ski there and look down. A shallow mountain stream flows down there. Open water. It’s comforting that the snow layer is more than a metre thick.

Now it’s only some more kilometres to ski back to the parking lot where I started my ski tour this morning. Although I’m avoiding the prepared ski trail it is obvious, that more and more skiers have been here the weekend. Ski tracks everywhere.

After round about 17 kilometres I’m back at the car. Pretty exhausted and thirsty but very satisfied.

Here’s a map from today’s ski tour. I went counterclockwise. Red is faster than green but still not fast. I’m not a downhill skier.

White beaked dolphins Feb 18 2023

This morning I got a facebook message. A colleague of mine had spotted marine mammals on Kvaløya.

I packed the camera and the big telephoto lens and took the car there. I drove around and also took the tunnel to the neighbouring island Ringvassøya but I couldn’t spot any. On the way back I turned into the side road to Kvaløyvågen where I saw a parked car with hazard lights and two people standing, one with binoculars. I asked them if there were any whales around and they affirmed.

And then I saw them too – a pod of at least ten animals. They swam against the current of the sound Kvalsundet and I could spot them for a while. I took some photos and cropped the images, because they were round 300 metres away.

I do not know anything about dolphins. According to my colleague it’s White beaked dolphins.

Thanks a lot for the tipp, M. . It was a special experience to spot so many dolphins from land. Without your message I would have missed them.

Coastal walk through the snow Jan 28 2023

Yesterday it was warm in Tromsø and it rained a lot. Last night it got slightly colder and today it snowed at +1 °C. I decided not to ski but to take a coastal walk by the shore of Kvaløya.

Especially the first half was a wet experience with some heavy snow showers coming from the front. The clouds seemed to start just above my head and I couldn’t see Tromsøya nor any mountains.

Although I have become pretty wet the way back was more comfortable. The wind was in the back, the snowfall decreased and finally I even could see the mountains again.

Round three hours later I arrived at the car. The luv side was plastered with wet snow. And I was glad that a had spare clothes in the car I could change into.

Two weekends in Tromsø Jan 17 2023

No, I will not write about this year’s warm January weather in Tromsø, the sleet showers, the icy roads, the rain today. I will write about the last two weekends.

Saturday, 7 January

My first ski tour this year. And since I’m a lousy downhiller I start again at the parking place at Finnvika on the island Kvaløya where terrain is not steep. At the parking place I meet a group of skiers, each with a dog but we have different directions and soon I’m alone and will be for the rest of the tour. It is not sunny – we still have polar night – but the sky is blue and bright. I ski cross-country, I’m too lazy no navigate. Slowly I gain high, it won’t be more than round 300 metres today.

The forecast is right, it gets windier and gustier by the hour and the snow is drifting over the barren rocks and the snow fields.

Some hours and 9 km later I’m back at the car. Some mountain tops have huge cloud-like objects in the lee. It’s drifting and blowing snow, a clear sign for high wind speeds.

Tomorrow I planned to take a tour to Sommarøya together with Marika who works at the Norwegian Polar Institute as well. We wanted to watch the waves in the storm.

Sunday, 8 January

Already the day before I changed plans. The weather service forecasted wind gusts up to 27 m/s. That’s not the weather where I want to cross wind-exposed bridges with my car. I just walk to the near shore to spot the waves there. Tromsø however is quite sheltered between mainland and the island Kvaløya and the waves are not so huge.

Saturday, 14 January

A lazy day. Nothing more to say.

Sunday, 15 January

I fetch Marika and we take the car to Sommarøya. No storm, no wave watching, just sightseeing and being outside. We stop at the road through the valley Gáhttovuonvággi (Sami) or Kattfjorddalen (Norwegian) to take photos from the mountains that shone brightly in front of the dark, purple clouds. They look harsh and untouchable.

On Sommarøya we walk around and visit some of the sandy beaches. Don’t let the clear, turquoise water fool you – it’s not the tropics and the water is ice cold. From the beaches and hills there are a zillion views to the mountains and islands around. It’s a beautiful spot, just an hour away and I should go there more often.

Next weekend?

Well, the weather forecast does not look too promising, but we’ll see. Maybe the next blog article shows only black-and-white photos.

An almost outdoor barbecue on Kvaløya Jan 7 2023

Some days ago I got a message from Elisabeth. She already had organised several events with friends and acquaintances – always outdoors – and in this message she asked me:

Lyst å bli med på grilling på fredag etter jobb?

“(Would you) like to join (us) for a barbecue on Friday after work?” That sounded like fun and I gladly accepted the invitation.

Friday evening was calm and clear and with -12 °C pretty cold for Tromsø – the coldest day this season. So I put some food and a lot of warm clothes with me. I met Elisabeth and two of her friends at the parking place and we went down to the barbecue hut by the sea. It looked like just a normal wooden house. Only without door, without window panes and without any floor. Instead of this a huge fire place in the middle.

More people dropped by until we were eleven people in total. Some of them had reindeer skins with them but they were hardly used. You know these parties where all people gather in the kitchen? It was a bit alike, all of us stood round the fireplace in the middle of the hut. Some to make stick bread or sausages, some to grill marshmallows or prepare waffles and some just to stay warm.

It’s always great to meet interesting, nice people. It gets however a bit harder when most of them are native speakers, because my Norwegian is still not so well. But it gets better and better. While I couldn’t take photos from the conversations I could take photos from the beautiful surroundings, even from within the hut. Remember, no window panes.

After three hours people started to leave. I was the last one left, just to take some more photos, then I took the car home as well.

Thank you Elisabeth for the organisation and for inviting me. Or more Norwegian: takk for i går – thanks for yesterday!

The first frost – hiking tour on the Laukviktinden Oct 2 2022

Today was the second day, where my car was covered with ice in the morning. I had to scrape ice after breakfast because I wanted to drive to Kvaløyvågen on the island Kvaløya to hike up the Laukviktinden (587 m) today. The weather was calm and the sky was blue and I enjoyed the views on sea and mountains from the car.

When I passed the shallow bay Finnvika I just had to stop and go there. Large areas were covered with a thin layer of ice that sparkled in the sun. Autumn in Tromsø is a fast season. Last weekend the trees were colourful, now many of them are bare.

20 km later: I just parked my car by the sea and read the tour description. I should follow the road for 80 metres, take the gravel road to the left and leave it when it turns left. The rest of the tour would be pathless but according to the book easy to find.

When I left the gravel road the terrain was a bit tricky. It was more or less overgrown boulders with hidden holes. The trees had shed their leaves and almost looked dead. I was glad when I had reached the mountain ridge where it was much easier to walk. The wet moss was covered with frost and so were the water puddles. Laukviktinden came into view, but I knew that there would be an acsent before. It looked pretty steep. Hopefully it’s just the perspective.

And indeed it was less steep than expected. A bit tricky however because some parts were wet and slippery. And that one of the countless moss pads hid a knee deep water puddle was not nice ;-) ! It is always a satisfying experience when you gain altitude, are above the tree line and can see more and more – both fjords and mountains.

Just straight ahead I spotted the lake Laukvikvatna and its neighbours. They lie 50 metres below. So I first had to climb down before hiking up again. Most of the lakes were covered with a thin layer of ice.

From the lake it is only 200 more metres in altitude to the top – according to the tour book. That meant that most of the the ascent lied behind me. It was easy to go up, only the very last part was a steep boulder field. Probably not the best routeI chose, but that was hard to see from below.

The terrain flattened out and then – all of the sudden – I could see the summit marker: A huge pile of stones with a metal box containing the summit book. And behind that: The open sea with the island Vengsøya.

What do you do on mountain summits beside of adding your name to the summit book? Yes – you take a selfie! After that I went a bit further to a place where the terrain drops off steeply. Here the view was really impressive because I could not only see the open sea and its islands but the bay Laukvika and even the boggy marshland that looked like it was directly under my feet. Here I took my iPhone as camera because it has a wide angle lens.

I took a break, ate some cookies and drank water. I even met another hiker that probably hiked up twice as fast as me. Then I started my way back. I found a better way because it is so much easier to find a good path when you look from above. Later my optimism was dampened when I landed in quite steep terrain and had to traverse it a bit until I was on my old trail.

Round 9½ km later I reached the gravel road again. In the shadow the ground was still frozen, but the car that waited in the sun was warm.

Grønnlibruna and Petterbolhaugen Sep 25 2022

It’s Sunday. Weather forecast looks very promising and I want to go out hiking. I scroll through my tour book and the net and cannot decide. Finally I just grab my stuff and the book and take my car to Kvaløya where I mostly use to hike. I’ll find something.

While driving I remember the small mountain Grønnlibruna where I’ve been already in November and May. There’s a lot of birch forest in the first half of the hike – perhaps a good place to be in autumn. I drive to the place where the tour starts and park my car.

The sky is covered with clouds and clouds flow through the valleys as well. But the yellow birch leaves of the forest I’m hiking though shine colourfully.

I reach the top of Grønnlibruna. Although it is only 401 metres high I am above the tree line. I continue to a smaller hill in the southwest to enjoy the autumnal colours. Later I’ll learn that it has a name: Petterbolhaugen. I reach the top and just in this moment the sun comes out. It already had started to illuminate small parts of the impressive mountains but now it shines on my face.

The weather become sunnier and sunnier and the views on the mountain panoramas are beautiful.

Many trees have lost already many leaves and even tiny puffs of wind take more leaves with them. Soon the colourful autumnal tinted forests will transform into grey collections of bare trees. Then I will hope for the first snow. But today I collect the colours – for the blog, my memory and my soul.
