Coordinate Systems
This is measured East and West in a geographic coordinate system.
What is Longitude?
The conversion of data from a curved surface to a map’s 2d plane could cause distortions in data’s direction, distance, area, and this.
What is shape?
This scale size is best for maps representing relatively small areas.
What are large scale maps?
Latitude and longitude are measured in these three units.
What are degrees, minutes, and seconds?
An equidistant projection preserves these.
What are distances?
A small-scale map is typically smaller than this ratio.
What is 1:100,000?
A projected coordinate system has constant lengths, angles, and these in its two dimensions.
What are areas?
This projection type preserves the direction of the data.
What is an azimuthal projection?
A distance of 15km in the real world would measure this long on a map of 1:50,000 scale.
What is 30cm?
