National Cartographic Information Center (Continued) 
NCIC uses the latest techniques of micro- 
photography and computer technology to manage 
the vast amount of information and to provide a 
focal point for information on data produced and 
distributed by many Federal sources. NCIC also 
provides information on some Federal plans for 
future data collection. 
NCIC does not obtain the cartographic data 
from present holders; rather it collects and 
organizes descriptive information about the 
data, tells where they are located, ensures 
their availability, and provides ordering 
assistance. Government and private data centers 
continue to hold and distribute cartographic 
data. Some of these centers also provide local 
users with direct access to NCIC information 
through their public service facilities; thus 
Many government and private organizations are 
cooperating with the USGS in forming a network 
of NCIC, facilities 
The USGS and the National Oceanic and 
Atmospheric Administration are the principal 
affiliates in the network. 
NCIC provides different levels of service 
for the various types of cartographic data. For 
general-purpose data-topographic maps and aerial 
photographs, the objective is to provide com- 
plete service, including the identification of 
specific products and assistance in ordering 
these products. On the other hand, only general 
information and a referral service are provided 
for special-purpose cartographic data. The 
types of cartographic data for which NCIC offers 
assistance are listed on the following page.
