National Geographic - TOPO! for ArcGIS
Overview:
TOPO! for ArcGIS - Multi-layer Edition
The Fastest, Most Accurate Way to Add TOPO! Base Maps, DEMS
and Hillshades to Your Projects.
TOPO! for ArcGIS is the only topographic map solution that integrates
directly with ArcGIS. This extension adds a toolbar to ArcMap that directly
accesses raster maps and data from the National Geographic TOPO! State
CD-ROMS (sold separately). The toolbar also makes it easy to locate and
manage maps and data in your project. With one click, you can select the
maps and layer(s) you want and import them into your project as georeferenced
data. Layers can be toggled on and off, and transparencies, color ramps,
and visible scale ranges can be adjusted separately. Small file sizes make
using TOPO! for ArcGIS fast and easy to use!
Designed for ArcGIS, TOPO! for ArcGIS gives you professional-level graphics,
using next-generation DEM and topographic hillshade data. It's all you
need to ensure that your project is run smoothly, economically, and efficicently.
Introducing TOPO! Digital Elevation Models
TOPO! DEM gives you the option to add digital elevation data to your
coverage area. Elevation data is essential to a wide range of GPS applications.
TOPO! DEMs merge the highest resolution, best quality elevation data available
from the USGS 1 arc second / 30 meter National Elevation data set into
a seamless raster format. As a layer in ArcGIS this data can be used with
a color ramp for creating natural background imagery, modeling landforms
in three dimensions, slope and aspect analysis, and understanding drainage
networks and watersheds.
Use TOPO! DEM by itself, or with either TOPO! Base Maps or TOPO! Hillshade
for astonishing and accurate depictions that bring your project to life!
Combine TOPO! Base Maps with TOPO! Hilshade and TOPO! DEM for spectacular
results!
A single source for quad maps, hill shade, and DEMs not only reduces
costs but guarantees alignment between layers. Toggle layers on and off
individually, adjust their transparency levels, or apply a color ramp to
create the exact base map you need.
Tasks made simple
TOPO! for ArcGIS gives you faster work flow and better results. An
easy-to-use toolbar automates the repetitive tasks associated with importing
and managing multiple raster data files. All TOPO! data layers are stored
unprojected and referenced to Geographic NAD83, which enables ArcGIS desktop
products to display them in any map projection of your choice.
