Problems with maps of different projections

The two pictures below are a line drawn with two points of equal latitude and longitude. (Thinkgeo / Bing map)

Depending on the difference in the map projection method, the below problems

Is there a way to solve this problem?

79 23.034 N
055 06.445 E

35 49.069 N
038 35.039 W

Hi Binary,

It looks the line render correct in both of them, because they are different projection.

Could you please let me know more detail about your question?

Hello Etan,

I want to present coordinate data received from Bingmap in the same shape on the ThinkGeo map.

The further the distance between the two points, the greater the difference.

Is there anything that can be converted to draw on a thinkgeo map as shown in Bingmap?

For example, I wonder if there is a way to treat two points as curves based on projection rather than straight lines.

Best Regards

Hi Binary,

I think I understand your question.

If your line in image one is straight line, you want to make it render in the same area and it should be a curve.

Our map don’t have this API, but you can do something like this:

  1. Cut the straight line in image 1 to many vertexes. Currently line only have two vertexes, you add many vertex in this line and get a multiply line, the denser vertexes can get better curve.

  2. Re-project the multiply line, get a new multiply line. When you render it, it will looks like a curve.

Wish that’s helpful.

Regards,

Ethan
