Why Maps Can you use a square globe? Could you fold up a globe and put it in your pocket? Why do we need maps? What types are there?
Map Makers Cartography: map making Develop a way to put a curved surface onto a flat surface (Map Projection) Mercator Gnomonic Conic Are the most common projections
Wrap a cylinder around a globe. Meridians appear straight. This creates distortion near the poles where the meridians normally come together.
Mercator Projection Compass directions appear as straight lines Latitude & Longitude are shown clearly and easily measured with a ruler. Shapes are shown correctly.
Imagine a sheet of paper touching a globe at one point (tangent) Little distortion occurs at the point of contact. It is usually the poles.
Gnomonic Projection There is a great distortion in both directions from the point of contact. Used in navigation of great circle routes Great circle appears as a straight line on these maps.
Conic Projection Cone placed over a globe so that the axis of the cone is aligned with the axis of the globe. Cone touches the globe along one parallel.
Conic Projection The area near the contacted latitude has the least distortion. Good for studying a specific area.
Polyconic Projection Placing many conic map projections together can give you a continuous map. The relative shape and size of small areas are the same as the globe.
Reading Maps Earth Science Mr. Bimber. Map Projections: You cant draw the round earth on flat paper, so all maps are distorted. Take a transparent globe.
III. Chapter 1.3 Representing Earth's Surface. Map Projections A map projection is used to portray all or part of the round Earth on a flat surface. This.
Goals: 1. Differentiate between latitude and longitude. 2. Understand that a topographic map is a 2-D model that displays 3D information 3. Describe map.
Maps Chapter 6, Section 3. Map Projections How is a map made? How is a map made? Points on a globe (3D) are transferred to paper (2D). May distort shapes.

How Can Objects on Earth be Located?. Types of Maps Cartography: study and practice of making geographical maps. Mercator Projections:Cyclindrical projections.
Where on Earth are we?. Globe to map? Projecting the Earth The position of a place on the Earth's is defined by coordinates of latitude and longitude.

Objective: To describe properties of solid shapes such as perpendicular and parallel lines, faces and edges.
Vertex-Edge Graphs. The Basics ❖ A vertex-edge graph is a graph that includes edges and vertices. ❖A❖An edge is a side (shown by a straight line) ❖ V❖
Solids in contact is in relation to cones, spheres and other cylindrical objects in contact. Sometimes you can get objects with flat surfaces also.
Understanding Coordinates NJDEP & ESRI: Understanding Map Projections & Coordinate Systems.
Three-dimensional Shapes (3D) These shapes are solid or hollow, you could hold them in your hand. They have three dimensions: length, width and height.
Solving 2-D Vectors Graphically Physics. Why? O You can and people have accurately represented a situation by drawing vectors to scale in order to recreate.
