TYPES OF PROJECTIONS IN TERMS OF THE DIMENSION TO KEEP


Equidistant 1.PROYECCIONES

"They keep the distances in certain directions.
"The lines that remain: AUTOMEC LINES
Anamorphosis-LINEAR - Linear Deformation in the rest of the addresses .= (distance measured in the projected / actual Distance)
ANAM AUTOMEC-lines. LINEAR = 1
-Used when you want to measure from a point
2.PROYECCIONES COMPLIANT
"They keep the angles as each pair of curves in the field (the tan) and its lines represented.
"Anamorphosis ANGLE: The difference between the principal and the angle of the sphere.
He used charts
-Parallel (Upright) Meridian
3.PROYECIONES EQUIVALENTS
-Maintain the surface of any shape
SURFACE-Anamorphosis is the ratio between the area of the map and reality
"They are generally used for thematic maps, parcel
4-PROJECTIONS AFILACTICAS or anaphylactic
"Do not retain any previous magnitude but errors (Anamorphosis) are close to a

GEOMETRIC CLASSIFICATION

BY THE POSITION:
"POINT OF VIEW PROJECTION or VERTICE
DESIGN-CENTER (tangency)
I-projected plane, or azimuthal OUTLOOK
It is planned to sup. Land a plane

II-DEVELOPMENT PROJECTIONS
It is planned to sup. Land on a sup. Geometric (-cone-cylinder)
I-FLAT CHARACTERISTICS OF PROJECTIONS
-Circles passing through vertex of P -> Straight lines
Pts equidistant from the vertex-projection-> equidistant from C. of Proj.
-Surfaces equidistant from the center of P. -> Same deformation
CLASSIFICATION OF P. FLAT
A-LEVEL FOR THE POSITION (CENTER OF PROJECTION)
1.Plano perpendicular to the axis. Center pole-> Polar, Equatorial
2.Plano perpendicular to Ecuador. Center on the Ecuador-> Meridiana, transversal
3.Plano perpendicular at any point-> Oblique, direct, horizontal, overhead
B-BY PROJECTION VERTICE
1.GNOMONICA or CENTRAL-> PTO OF VIEW IN THE CENTRE OF THE EARTH
"It is projected throughout the hemisphere
-The maximum-orthodromic circles-> Straight
Large-deformation to get away from the center of projection
2.ESTEREOGRAFICA-> PTO opposite view to PROY CENTER
"It's under (keep the angles)
"It can be a hemisphere
"Circles in the field-> circle in the plane
If the circles pass through C of P-> R are circles
"In circles centered on the scale is constant-CP
"When there are lines that intersect under the angle meridians cte-> rhumb-> logarithmic spirals
3.ORTOGRÁFICA-> PTO OF VIEW IN THE INFINITE
-Field is a hemisphere maximum
4.ESCENOGRAFICA-> EXTERIOR VIEW NEXT PTO
1.71 R-AHIR
1.594 R-PARENT
1.69 R-LOWRY
1.76 R-FIORINI
