processing tabular data

Look at Google Earth Image

Look at Google Earth Image

Converting XY Table into Point Feature Class Get longitude (X) and Latitude (Y) from Google Earth http://support.esri.com/es/knowledgebase/techarticles/detail/27589

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

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

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
