  • Chapter Six: Digitizing, Creating, and Editing Data

Chapter Goals

  1. Define and explain manual or hardcopy digitizing see digitized
  2. Define and explain heads-up or on-screen digitizing see digitized
  3. Explain when manual or heads-up digitizing see digitized might be used
  4. Define and explain Remote Sensing
  5. Know when remotely sensed images are used in GIS Geographic Information Systems the software used to create, store, and manage spatial data Data that deals with location, such as lists of addresses, the footprint of a building, the boundaries of cities and counties, etc. , analyze spatial problems, and display the data in cartographic layouts   Geographic Information Sciences
  6. Define spatial resolution Spatial resolution refers to the level of detail or granularity in an image or a spatial dataset.
  7. Define temporal resolution One of four resolutions (or the resolving power) used to describe raster data (spatial resolution, spectral resolution, temporal resolution, and radiometric resolution)Temporal resolution refers either the the time period a single raster is valid for (if applicable) or the return interval of a particular sensor which captures remotely sensed data. For example, LandSat collected imagery of a location every 14 days.
  8. Define and explain basemaps
  9. Define and explain georeferencing
  10. Know when georeferencing is necessary
  11. Generally describe the process of georeferencing
  1. Generally describe the process/steps of creating a new shapefile One of the two main types of vector data in any sort of digital science or art, is simply denoting a type of graphical representation using straight lines to construct the outlines of objects we learn in this class (there are more than two vector data in any sort of digital science or art, is simply denoting a type of graphical representation using straight lines to construct the outlines of objects types in GIS). Shapefiles are each only one geometry type, either a point, a polyline, or a polygon. Shapefiles are stored in folders and most often do not have relationships with other data. or feature class One of the two main types of vector data in any sort of digital science or art, is simply denoting a type of graphical representation using straight lines to construct the outlines of objects we learn in this class (there are more than two vector data in any sort of digital science or art, is simply denoting a type of graphical representation using straight lines to construct the outlines of objects types in GIS). Feature classes are each only one geometry type, either a point A GIS vector data in any sort of digital science or art, is simply denoting a type of graphical representation using straight lines to construct the outlines of objects geometry type which is made up of just one vertex pl. vertices One of a set of ordered x,y coordinate pairs that defines the shape of a line or polygon feature. , marking a single XY location in any given geographic or projected coordinate system. , a polyline A GIS vector data in any sort of digital science or art, is simply denoting a type of graphical representation using straight lines to construct the outlines of objects geometry type which is made up of two or more vertices connected by straight lines. Often used to represent objects such as roads, river, and boundaries. , or a polygon. Feature classes are stored in geodatabases and are most often used when data relationships are important.
  2. Define and explain geocoding and reverse geocoding
  3. Define GPS
  4. Recognize GPS data collection applications for GPS recievers and smartphones/tablets
  5. Define and explain crowdsourcing
  6. Define and explain direct feature editing and attribute table editing
  7. Know the difference between the Define Tool and the Project Tool, including when to use each one
  8. Define and explain geographic transformation, including when and when not to use one
  9. Know the difference between Field Calculator and Calculate Geometry, including when to use each one
