  1. processing tabular data

  2. Look at Google Earth Image

  3. Look at Google Earth Image

  4. Converting XY Table into Point Feature Class • Get longitude (X) and Latitude (Y) from Google Earth

  5. longitude (X) and Latitude (Y) from Google Earth • Save in Excel • Convert in Decimal Degree format • Add Excel worksheet in ArcMap • Add Data > Add XY Data (geographic coordinate system, WGS 1984) • Select a coordinate system for the data • Points will be drawn as an event theme in ArcMap

  6. Convert the event theme to a shapefile or geodatabase feature class • Right-click the file name, select Data > Export Data • Points can be exported to a geodatabase feature class or to a shapefile • Re-project to the UTM coordinate system

  7. Quiz • Re-project to the UTM coordinate system

  8. Georeferencing • Save Google Earth Image (jpeg) • Select Ground Control Points (GCP) • At least 3 points are required for Affine (1st Order polynomial transformation) • Add Georeferencing tool bar • Apply ‘Fit to Display’ on the image • Add GCPs • Update Georeferencing when satisfied • Rectify for permanent transformation
