Introduction

Data View lets you browse underlying textual information for all of the features in a layer in a spreadsheet-like format. A layer is made up of features which can be either points, lines or polygons. These features can be represented by a symbol, text, line or an area. These features also have text information attached to them called attribute data. Attribute includes information like the features name, features size, or where the legal definition of a feature can be found. Attribute data can be viewed by using the 'Data View' or the 'What's Here?' tool. Data view can be used to view attribute information and highlight, select and sort features.  You may also export the information from data view.

Feature Description
Access Data View 'Data View' lets you browse all the objects in a layer in a tabular format, select objects of particular interest, and see these highlighted or featured on the map. 'Data View' only appears when the active layer has objects that can be browsed.
  • Select the Map Legend Tab.
  • Select a Layer with the 'Data View' function (eg Commercial Catch), and click on the 'Data View' tool from the Layer tools list.
  • The 'Data View' page appears, showing the objects on the layer in a table.
Browse Objects
  • The scroll bars at the side and bottom of the table let you browse the objects to find those of interest.
  • If there are too many objects for one page, you can move from page to page using the 'Previous [1] [2] Next' page selection hyperlinks.
Select Objects
  • The tick boxes on the left of the table let you select objects by clicking in the box.
  • To remove a tick, click the ticked box again.
Sorting Using Column Titles
  • If you click on a column title the table will be sorted in ascending order on the data in that column.  Click the same title again to sort descending.
Return to Map
  • To return to the map as it was displayed before going into 'Data View', click the 'Proceed to Map' button.
Highlight Selected Objects on Map
  • If you click on the 'Highlight selected objects on map' button the objects you have selected will be highlighted in yellow on the map. A yellow triangle will appear beside the 'Legend Layer Title' for the layer, to indicate that there are highlighted objects.
  • NOTE - some selections may not be shown if the map layer has a maximum zoom level set.  For example if the map is set to come on below a window width of 100km.  If you selected more than one feature and they are further apart than 100km they will not show up as the map has to zoom out to encompass both of them.
Show Selected Objects on Map
  • If you click on the 'Show selected objects on map' button, only the objects you have selected will be shown on the map, all other objects from that layer will be removed.
  • The set of selected objects are shown as a new layer on the legend called 'Selected [layer title]' and the layer on which the selection layer is based is displayed as 'Hidden' on the legend. To see the total layer again, select 'Show Layer' from the Menu List for that layer.
  • NOTE - some selections may not be shown if the map layer has a maximum zoom level set.  For example if the map is set to come on below a window width of 100km.  If you selected more than one feature and they are further apart than 100km they will not show up as the map has to zoom out to encompass both of them.
Export Data This button will export the information contained in data view for the chosen layer.  It gives you the option to open or save the information as a .csv file.  This will open in excel.  You can then save it off as an excel file to allow formatting to be applied to it.
