What are the standard parallels for the North America Albers Equal Area Conic and the USA contiguous Albers Equal Area Conic?

Used for the conterminous United States, normally using 29°30′ and 45°30′ as the two standard parallels. For this projection, the maximum scale distortion for the 48 states is 1.25 percent.

What are the standard parallels for the North America Albers Equal Area conic coordinate system?

Uses and applications Used for the conterminous United States, normally using 29°30′ and 45°30′ as the two standard parallels. For this projection, the maximum scale distortion for the 48 states is 1.25 percent.

What should be the range of Albers equal area conic?

Total range in latitude from north to south should not exceed 30–35°. No limitations on the east–west range. Used for small regions or countries but not for continents. Used for the conterminous United States, normally using 29°30′ and 45°30′ as the two standard parallels.

What’s the maximum distortion of an east-west conic?

No limitations on the east–west range. Used for small regions or countries but not for continents. Used for the conterminous United States, normally using 29°30′ and 45°30′ as the two standard parallels. For this projection, the maximum scale distortion for the 48 states is 1.25 percent.

How are two standard parallels used in conic projection?

This conic projection uses two standard parallels to reduce some of the distortion of a projection with one standard parallel. Although neither shape nor linear scale is truly correct, the distortion of these properties is minimized in the region between the standard parallels.

How are all areas proportional to the same area?

All areas are proportional to the same areas on the earth. Locally true along the standard parallels. Distances are most accurate in the middle latitudes. Along parallels, scale is reduced between the standard parallels and increased beyond them. Along meridians, scale follows an opposite pattern.

What are the standard parallels for the North America Albers equal area conic and the USA contiguous Albers equal area conic?

Used for the conterminous United States, normally using 29°30′ and 45°30′ as the two standard parallels. For this projection, the maximum scale distortion for the 48 states is 1.25 percent.

What is Albers USA?

Albers USA is typically the go-to projection for US Elections because it shows a non-distorted Alaska and Hawaii in close proximity to the rest of the states. However, Mapbox basemaps are rendered in a web mercator projection by default.

What are the disadvantages of conical projections?

Like all projections, the Albers Equal Area Conic Projection has map distortion. Distances and scale are true only on both standard parallels with directions being reasonably accurate.

What should be the range of Albers equal area conic?

Total range in latitude from north to south should not exceed 30–35°. No limitations on the east–west range. Used for small regions or countries but not for continents. Used for the conterminous United States, normally using 29°30′ and 45°30′ as the two standard parallels.

What’s the maximum distortion of an east-west conic?
