Data Considerations

CV-25 - Metadata, Quality, and Uncertainty
  • Describe a scenario in which possible errors in a map may impact subsequent decision making, such as a land use decision based on a soils map
  • Evaluate the uncertainty inherent in a map
  • Compare the decisions made using a map with a reliability overlay from those made using a map pair separating data and reliability, both drawn from the same dataset
  • Critique the assumption that maps can or should be “accurate”
CV-20 - Raster Formats and Sources
  • Explain how color fastness and color consistency are ensured in map production
  • Compare outputs of the same map at various low and high resolutions
  • Differentiate among the various raster map outputs (JPEG, GIF, TIFF) and various vector formats (PDF, Adobe Illustrator Postscript)
  • Compare and contrast the file formats suited to presentation of maps on the Web to those suited to publication in high resolution contexts
  • Compare and contrast the issues that arise for map production using black-and-white and fourcolor process specifications
  • Outline the process for the digital production of offset press printed maps, including reference to feature and color separates, feature and map composites, and resolution
  • Critique typographic integrity in export formats (e.g., some file export processes break type into letters degrading searchability, font processing, and reliability of Raster Image Processing)
  • Prepare a map file for CMYK publication in a book
  • Prepare a map file for RGB presentation on a Web site
  • Discuss the purpose of advanced production methods (e.g., stochastic screening, hexachrome color, color management and device profiles, trapping, overprinting)
CV-03 - Vector Formats and Sources
  • List the data required to explore a specified problem
  • Discuss the extent, classification, and currency of government data sources and their influence on mapping
  • List the data required to compile a map that conveys a specified message
  • Discuss the issue of conflation of data from different sources or for different uses as it relates to mapping
  • Describe a situation in which it would be acceptable to use smaller-scale data sources for compilation to compile a larger scale map
  • Describe the copyright issues involved in various cartographic source materials
  • Explain how data acquired from primary sources, such as satellite imagery and GPS, differ from data compiled from maps, such as DLGs
  • Explain how digital data compiled from map sources influences how subsidiary maps are compiled and used
  • Explain how geographic names databases (i.e., gazetteer) are used for mapping
  • Explain how the inherent properties of digital data, such as Digital Elevation Models, influence how maps can be compiled from them
  • Identify the types of attributes that will be required to map a particular distribution for selected geographic features
  • Determine the standard scale of compilation of government data sources
  • Assess the data quality of a source dataset for appropriateness for a given mapping task, including an evaluation of the data resolution, extent, currency or date of compilation, and level of generalization in the attribute classification
  • Compile a map using at least three data sources
