Mercator map projection - Study guides, Class notes & Summaries

Georeferencing Associating a map (such as a pdf without spatial information) or image (such as an aerial image without spatial information) with spatial locations. Control Points Consisting of multiple points, points come in pairs that match the spatial location with a point on an unreferenced image or map. Spatial Reference System (SRS) or Coordinate Reference System (CRS) A coordinate-based local, regional or global system used to locate geographical entities. International Terrestrial Refe...

Geomatics - the modern scientific term referring to the integrated approach of measurement, analysis, management, storage, and presentation of the descriptions and locations of spatial data Spatial Data - data that is collected using a variety of methods including earth orbiting satellites, air and sea-borne sensors, and ground based instruments data is processed and manipulated with state-of-the-art information technology using computer software and hardware Surveying - art of measuring d...

Control Survey: Lambert Projection correct answer: An imaginary cone is placed around the earth so that the apex of the cone is on the earth's axis of rotation above the North Pole, for northern hemisphere and below the South Pole for southern hemisphere projections. East west direction is relatively free from distortion in this method. Therefore, states longer in east-west direction are projected with this system, Scale is set for 158 miles of N/S distance in this method. Transverse Merc...

Where do our ideas about places come from? - our knowledge of the world is mediated -- media, culture, the internet, school, art, etc. etc. etc. - experiences aren't immediate/direct what are geographical imaginaries? - the collection of assumptions and ideas that we have about places what does geographic literacy entail? - asking the questions: - where does this idea come from? - who made/organized them, and for what purpose? - do they have merit? - do they occupy the correct amount...

GISP Study Already Graded A+ Georeferencing and Control Points - Georeferencing: The process of associating a map or image with spatial coordinates to accurately represent its geographic location. - Control Points: Specific points that correspond in pairs, matching known spatial locations to points on an unreferenced image or map. Spatial Reference Systems - Spatial Reference System (SRS): A coordinate-based system—local, regional, or global—used to locate geographical entities, al...

Interrupted Map correct answers Removes parts of the globe to prevent distortion Uninterrupted Map correct answers Displays the entirety of the earths surface but may cause more areas of distortion Mercator Map Projection correct answers Shows accurate direction but has significant distortion in size of land marks Goode Homolosine Projection correct answers Shows true size and shape of land masses but has distortion near edges of the map and is not good for directions Robinson Projec...
