'What's Here?' Tool

Introduction

Using the 'What's Here?' Tool

Introduction

This tool provides information about the data layers that have features at a selected point of interest. 

 

There are two 'What's Here?' tools:

1) Button on the map tool bar - selects features for all layers loaded on the map.  

2) On a layers legend tile - under 'Layer Tools' - selects features for an individual layer only.

 

NOTE there are some exceptions - selected place names and measured distances will not be picked up by this tool, nor do they have it available on their legend.

How to Use the 'What's Here?' Tool

Name Description
'What's Here?' tool Lets you investigate features on the map.
  • Select the 'What's Here?' option from the layer tools available in the legend of the active layer or on the layer tools menu.
  • Click on a point on the map where you are interested in a feature, the tool will find features where you click.  The tool will pick up features within a small distance from the point you click so you don't have to worry about clicking the exact point of a feature.
  • Information on all features at the selected point will be displayed.
  • This information may be printed using the 'File, Print' option on your browser menu, 
  • To return to the map select 'Back' on your browser menu, or 'Proceed to Map' at the bottom right of the screen.
Selection area The features found by the tool depend on the scale of the map at the time.  Most features are set to be selected within a 3 pixel measurement.  This varies but to get an idea - at a window width of 815km a 3 pixel measurement equates to approximately 2km.
Selecting features near to the coastline Some coastal features are harder to find at a small scale or "zoomed out" scale.  This is because they are slim line feature which only exist for a few meters near coastline.  For more accurate use of the tool zoom in to your area of interest.
Best use of tool Again, for more accurate use of the tool zoom in to your area of interest. Some features are small and it can be difficult to select them at a large scale.

 

Note for those of you that use the Import My Points function.  If you have displayed polygons and one has a self intersect (lines crossing over) the "What's Here?" tool will bring back an 'invalid' type error.  NABIS can display them but cannot calculate the area for this type of polygon.

Here is an example of an invalid polygon:

 

Example of an invalid polygon - it has a self intersect.
