NVIZ Reference Manual

CONTENTS

What's Here Panel

The What's Here panel lets you interactively query surfaces, vectors and sites displayed in the NVIZ viewer. Query results appear in the What's Here text box. You can also pipe results directly to a text file. Query points appear in the NVIZ viewer as icons.

OPTIONS

What's Here?

Turns the What's Here interactive query on and off.

Attributes

Lets you select optional output query attributes.

Map Name

Names the query map (surface) used.

Easting

Provides the easting of the query point.

Northing

Provides the northing of the query point.

Elevation

Provides the elevation of the query point.

Color Category

Provides the surface color (as RGB) of the query point.

XY Dist from Prev

Provides the horizontal distance (XY) between the current and the previous query points.

XYZ Dist from Prev

Provides the actual distance (XYZ) between the current and the previous query points.

Dist Along Surface

Provides the overland (draped) distance between the current and the previous query points. If selected, a line draws between the current and the previous query points.

Dist Along Exag Surface

Provides the overland (draped) distance between the current and the previous query points using vertically exaggerated elevations. The vertical exaggeration used in this calculation comes from the surface zexag value. If selected, a line draws between the current and the previous query points.

Postgres

Queries the selected (g.select.pg) database based on results from the current query point.

Reset

Adds a horizontal line to the query output.

Clear

Clears the What's Here panel text box (query results).

Query vector

Uses the query results from selected vector (see Query map) to query a selected (g.select.pg) Postgres database.

Query sites

Uses the query results from selected sites file (see Query map) to query a selected (g.select.pg) Postgres database.

Query map

Selects the file (vector or sites) to use for the Postgres query. If you select Query vector, provide a vector map name. If you select Query sites, provide a sites file name.

PG Table

Enter the name of the Postgres table. The table must be in the currently selected Postgres database.

key col

Enter the name of the column in the Postgres table. The column must be in the currently selected table.

Xcol

Enter the name of the easting column in the selected Postgres table. Use only with the Query sites option.

Ycol

Enter the name of the northing column in the selected Postgres table. Use only with the Query sites option.

Dist

Enter the radius from the selected query point to search the Postgres Xcol and Ycol. In other words, return all of the database records within the set distance from the selected point.

Pipe to

Outputs query results to a user defined text file.

Close

Closes the What's Here panel.
