Example 2 – Single Picture Mode – Vienna

Task: Somebody gave us Gauss-Kruger coordinates from a map in Austria showing some object. We want to download image of that object and match the coordinates to the map. Coordinates were given: Y: 5602120, X: 5341494, and were taken from Austrian map made in Austrian Hermannskogel Local Datum. We want to see surrounding of the object, maybe 200 meters on each side. We want to use Bing maps and Aerial map type, so we get pure image without any labels. Output should be in .Bmp format with appropriate world file. 

Solution:

We will focus on square Y:5602000-5602400 and X: 5341300-5341700. 

First we setup desired Map source: 

Then we select Coordinates format: 

Then we select desired output format: 

Then we set Map Download Parameters and click download button:

We can preview source map area:

If you look carefully into picture above you will notice that Gauss-Kruger grid is not aligned with geographic grid. There is an angle between Gauss-Kruger grid and Geographic grid, called “Meridian Convergence”. Gauss-Kruger grids do not go perfectly North-South all the time. That is why we have 2-step process, first get “source image” containing area of interest, and then  perform transformations on selected rectangle to convert it into Gauss-Kruger grid and get final image. 

We can preview final map area:
