At the beginning of the year we announced that ArkivDigital had acquired several million aerial photographs from Svenska-Aero Bilder. Click here to see the earlier blog. During the half year since then, boxes and boxes with maps, negatives and paper copies have been transported to our office in Lyrestad. Once in place, scanners, digital cameras and computers have been working at full speed. We are far from being complete, but we want to show you a little of what we have done.
In order to view the aerial photo collection, one must have an All-in-one subscription and access the service by using the web version of our program software.
First, we want to say it is not easy to find the right picture. You must understand the layout, abbreviation and codes. In addition, not all the photos have yet been scanned and thus are not yet available. So, with these reservations, we will try to explain the steps for finding the correct image.
In this example, we will search for an aerial photo from the small village, Dalstuda, which lies in Rättviks parish in Koppparberg county in Dalarna province.
First, we go to archive search and select the archive type, Flygbilder, and then we see what is available. Note – that we are continually adding new material.
Search for “Flygkartor Kopparbergs län” and then select a volume. Each company has photographed their own maps. In this case, we will select SAB:1 (Svenska Aero Bilder).
The different navigational flight routes are on the overview maps. Locate the map that covers the region or area you are searching for.
Enlarge (zoom in) the image to see the code number.
We have now discovered that this is image series E6952 which we shall now search for in the Svensk Aerobilders volume. Select Svenska Aero Bilder Råkopier E:XXXX (SAB). The beginning letter in the image series in this case is E.
We are now coming close. In the long list, we will find the image series E:6952 and we open the volume by double clicking the volume.
Now the image series is open and you can page through it in order to look at the images for that flight route. There can be a few images or as many up to a hundred photos. Unfortunately, today there is not a better description of which houses and farms have been photographed.
Remember to also look at the back of the card (image after photo), there may be some information about who ordered the image. There may be some information noting that one wants the photo trimmed.
In conjunction with the flight route notations on a map, logs were also created, named tagningsrapporter or filming reports.
Today, we are asking for your assistance, even before we have built a proper support system for marking the individual houses and farms on a map.
There is no more detailed information than a number on an image series and an approximate route where the helicopter/airplane has flown when taking the photos for that series. The individual houses are not named. You who have lived or grown up in one place have the detailed knowledge about these houses or farms and if you want to help us identify them, we and other curious users will be very thankful.
When you find a house or farm and you know where it is located, do the following:
- Open your email application and send a mail to firstname.lastname@example.org.
- In the mail, note the AID and the coordinates for the house or farm.
- Send the mail.
AID is our identification to an image. This number can be obtained in different ways, e.g. by copying what is in the field or Copy Source Identifier which is circled in red in the image below. Once you have copied the number to your computer’s memory, paste it into your mail by going to the mail message and pressing Ctrl + v or right click with the mouse and in the menu which appears, select, Paste.
Find the coordinates
An easy way to find the coordinates is to use Google Maps: https://www.google.se.
- Enter the location if you know the address or nearest city in the search bar in the upper left corner. If there are multiple places with the same name, select the one that is correct.
- The map is now zooming in and you get a mark on the center of the site. If it’s a village or a city, usually the center is highlighted.
- Zoom in further by using the mouse wheel or +/- down in the right-hand corner of the map.
- You can move around by holding down the left side of the mouse and dragging the image.
- You can either view a map or a satellite image. Click on “Satellite” at the bottom left to switch to satellite view.
- Click on the house or farm in the Google satellite map that is the same as the image in ArkivDigital and an image will appear below with the coordinates for the place.
- Copy this information (right click and select copy) and paste this into the mail message that you send us.
You mail the following information to us:
AID number of the image – e.g. v862785.b31
Address coordinates – e.g. 56.841445, 13. 927757
We will save this information so that we can use it in the future. Thank you for your help.
We are aware that it is quite difficult to search for the right image, but this is a beginning and we hope that together we will enhance the product so that one can easily find the correct photo. We will be writing more blogs in the future about these aerial photos and the collection development.
