Elevation Tools
V7 products include elevation models that extend All
Topo's usefulness to a third dimension!
- Elevation at Cursor. more...
- Path profiles between two points or along an
arbitrary traced path. more...
- Elevation ranking: finds and ranks high/low
elevations. more...
- Line-of-Sight Tool: quickly determines what you can
see from a point, includes source and destination heights. more...
- Elevation data can be exported to standard DEM or XYZ
files. more...
- Beautiful, 24-bit hillshading and false elevation map
coloring. more...
All Topo's elevation database is the full resolution
(0.1 meter; 1 arc-second spacing continental US+Hawaii, 2 arc-second
Alaska) 'National Elevation Database' (NED) terrain model.
Any profile may be exported as a graphic image to the
clipboard, a file or printer.

| Elevation
at Cursor / Waypoint
As the cursor moves over the map surface, the elevation
under the cursor is displayed:

You can choose to display the elevation in Feet, Meters
or Survey Feet.
You can also add elevation tags to waypoint descriptions
and notes. These tags are evaluated when the image is drawn or waypoint
lists are listed and exported. Adding %Elevf% to a waypoint description:

displays:

| Path
profiles between two points or along an arbitrary traced path
Any route connected features can be profiled by
right-mouse-clicking near any of the connected points and choosing 'Build
Profile...':

builds this profile:

Right-click near the base point of any path built with
the draw pencil:

choose 'Build Profile...' to see an elevation profile
along the path:

Change the profile's properties to control trace colors,
grid span, titles and earth curvature display. |
| Elevation
ranking: finds and ranks high/low elevations
Use the 'Elevation Rank' tool to quickly find the
highest point on a map:

All Topo will quickly search and display the highest or
lowest points on a map. You specify how many points you want to
find, and how far they must be apart. This is a handy tool for quickly
finding suitable repeater locations. |
| Line-of-Sight
Tool
All Topo will quickly compute line-of-sight coverage
from a single base point to all other points on a map. You can specify the
height above ground level for the rover and two heights at the base. All
Topo shows rover locations that can see either base heights with green
dots, purple dots designate rover locations that can see only the high
base height; red dots show rover locations that can not see either base
elevation.
To compute coverage select the main menu option:
"Tools: Elev Tools...: Line-of-Sight (tab)"; enter the
controlling information; finally press the 'Begin Computations...' button:

This tool is very handy for estimating radio coverage
(line of sight only, the K factor is not programmable), areas of concern
for visual corridors:
