1.
 The Overlays Menu Overlalys Menu contains the same basic Layer List/Overlays as on the LiDAR Map Page and are activated in the same manner (check mark). The Overlays Menu contains one (1) addition selection, a Survey Grids overlay.
Overlay List

The Survey Grid overlay consists of a grid of orange 500m x 500m squares that cover the islands. Each 500m x 500m square is numbered. The grid is used to designate a specific study area. Grid numbers become progressive larger as you move to the right and down the page.
The exact steps for using the "Survey Grids" is covered in Tutorial III: Find Assigned Study Area.

See the examples of the "Survey Grids" below showing small scale and large scale grids.

Small Grid      Large Grid

6.
The Delete Features button DeleteFetures allows you to clear ALL the features/vectors you have drawn on a LiDAR image so that you can start a new submission.
Make sure to save any work you have done before using this tool. The Delete Features button PERMANENTLY DELETES ALL the features/vectors that have been drawn on the LiDAR image.
You CANNOT retrieve work that has been deleted with the Delete Features button !

[Back to Input Application Menu]




7.
The Export Features button Export Fetures saves the features/vectors you have drawn on the LiDAR image to a file in the "downloads" directory of your computer (C:\Users\username\Downloads).
The file name appears in the following format:
      CSS_featuretype_mapsection(#).geojson
         [eg: CSS_Ch_Apata(1).geojson]
After saving, the name of the file appears in the lower left corner of the current web page screen. The ".geojson" (geojason) file is a text file containing information about the vectors that have been drawn. This file can be loaded into QGIS (a free Global Information Systems program that is available at: qgis.org) to display the features/vectors that have been drawn.
The exact steps for completing this critical part of the vectoring process are covered in Tutorial VII: Save/Export features.

8.
The Submit Features button Submit Fetures allows you to submit the work you have done via email to the Centre for Samoan Studies (CSS). This is a very important final step as it allows CSS to include your work in Utu - the Samoan Archaeology and Cultural Heritage Database for the Independent State of Samoa.
The exact steps for completing this critical part of the vectoring process are covered in Tutorial VIII: Submit features.
