If two of more line features are selected, the Find Non-Connected Line Endpoints option will appear when<br />

right-clicking. Selecting this will display a dialog allowing you to either mark all line endpoints that do not<br />

connect to an endpoint (not an interior vertex) of another selected line or those line endpoints that don't<br />

connect and are within some distance of another selected line endpoint. This is a very useful feature for<br />

allowing easy identification and fixing of connectivity issues within loaded vector data.<br />

Any line endpoints that do not connect based on the selected criteria will be displayed with a blue circle over<br />

that endpoint. Once you think you have fixed the connectivity issues at a location, simply re-run the command<br />

to find the non-connected line endpoints to update the display of the blue circles (they are not automatically<br />

updated as you join line endpoints).<br />

Finding Nearby Points<br />

If two of more point features are selected, the Find Selected Points Within ??? Meters of Other Selected<br />

Points option will appear when right-clicking. Selecting this will display a dialog allowing you to specify a<br />

search distance. Any selected point features that are within the specified search distance of another selected<br />

point feature will be displayed with a blue circle over that point. If you delete or move some points to remove<br />

duplicates (the primary use of this tool), simply re-run the command to find the to update the display of the<br />

blue circles (they are not automatically updated as you edit the data).<br />

Flattening Terrain Using Area Features<br />

<strong>Global</strong> <strong>Map</strong>per User's Manual<br />

If one or more area features are selected, the Advanced Feature Creation Options->Create/Flatten Terrain<br />

from Selected Area Feature(s) option will appear when right-clicking. Selecting this option will allow you to<br />

create a new elevation grid covering the selected area features that has all points within the selected area<br />

feature(s) set to the elevation of those area features. Any portions of the new elevation grid outside of the area<br />

features will be set to invalid, allowing any underlying terrain to show through. If you also select the option<br />

that elevations are relative to the height of any underlying terrain, the new terrain surface will have heights<br />

equal to the original height of the terrain at each sample location within the area offset by the elevation value<br />

of the area feature. This functionality is useful for adjusting all elevation values within an area by some<br />

amount (the area elevation).<br />

This feature provides a very easy way to do things like flatten an area, like a lake, in underlying terrain layers.<br />

Just assign an ELEVATION attribute to your area feature, then select it and choose this option to flatten<br />

everything inside that area to the elevation attribute value. This is also a nice way to create an elevation grid<br />

representing a city-scape from building outlines with ELEVATION attributes.<br />

Adding Address Information to Points from Nearby Road Features<br />

If one or more point features are selected, the Add Address Information from Roads to Selected Point(s) option<br />

will appear when right-clicking. Selecting this option will cause each point to be examined to find the nearest<br />

line feature, and, if it contains addressing information, for the address of the nearest point on the line to the<br />

point feature to be stored as address attributes with the point feature. A dialog will appear to prompt you for<br />

how far from each point that you want to search for a line feature with addressing information.<br />

The following attribute names for line features are recognized as containing address information:<br />

• FR_ADDR_R, R_FROM_ADR - starting address number on the right side of the road<br />

• FR_ADDR_L, L_FROM_ADR - starting address number on the left side of the road<br />

• TO_ADDR_R, R_TO_ADR - ending address number on the right side of the road<br />
