National Integrated Land System

Project Description
The National Integrated Land System (NILS) project is a phased
effort to develop a common data model and toolset for managing
land records in a Geographic Information System (GIS)
environment. The common data model and toolset will meet the
core survey and parcel management business requirements of the
Bureau of Land Management and the US Forest Service.

The four NILS models include:

1. Survey Management:

Survey Management is a set of applications that provides
surveyors with the ability to manage survey data collected in
the field. It allows for exporting data to a variety of survey
equipment and for importing data back into the Survey Management
database. GIS, raster, and field data are all integrated within
Survey Management for data validation and decision making while
in the field. Survey Management will provide field surveyors
with tools to research survey data that can be taken into the
field. Additional tools will assist in the calculation of field
data and observations. A subset of coordinate geometry and
layout calculation tools will also be available. Next
implementation is scheduled for March 2003.

2. Measurement Management:

Measurement Management is a desktop GIS application that allows
surveyors to analyze and adjust surveyed data from the
field. Measurement Management allows for the combination of
measurement data from a variety of sources and reliabilities to
create a seamless measurement network. Measurement Management
contains a suite of mathematical formulas that allow the
transformation of raw survey data into the measurement
network. This is referred to as the legal description
fabric. The legal description fabric can then be used to create
the parcel fabric, which can be used by land managers for
decision making.

Measurement Management contains tools to input and import data,
construct measured features, edit measurement data, adjust and
analyze the measurement network, perform least square
adjustments, perform coordinate geometry and layout, and create
a parcel fabric. Next implementation is scheduled for March

3. Parcel Management:

Parcel Management will be a desktop GIS application that
provides tools for land managers to create and manage parcel
features and their legal area descriptions. The parcel fabric
can be vertically integrated with survey features captured and
managed using the Survey and Measurement Management
applications. A set of tools for standardizing and facilitating
land management workflow processes will be provided with the
parcel management suite of tools.

4. GeoCommunicator:

GeoCommunicator is an interactive Web-based land information
portal, powered by ESRI's Geography Network, that uses the
Internet to effectively deliver maps, geographic activities, map
and image services, clearinghouses, spatial solutions, reference
documents, potential cost sharing partners, and much more to
individual user browsers and desktops, allowing data providers,
service providers, and users throughout the United States to
communicate, access, and share land-based information.
