摘
要:研究和总结了基于
web
service
的空间信息集成技术,提出了基于
web
service
的
NDVI
计算模
型服务架构,该方法可以实现空间计算模型的跨平台性和互操作性,大大提高空间计算模型的共享.
利用该方法对
NDVI
进行
web
service
的封装和网络发布,很好地解决了传统植被指数计算模型的共享
和互操作问题,也为其他空间计算模型的
web
service
集成与应用提供了参考.

Abstract:
Through
a
study
and
summary
of
the
web
services-based
integration
method
of
spatial
data
,
the
web services-based
integration
method
of
spatial
computing
model
was developed.
The
spatial
computing
models
based
on
this
method
can
be
run
on
various
operating
systems
and
can
be
used
between
different
software
applications.
The
sharing
and
interpretability
of
spatial
computing
models
can
be
improved
based
on
this
technique.
This
paper
took
NDVI
as
an
example
to
introduce
the
web
services-based
method
and
the
spatial
computing
model
was
encapsulated
based
on
web
services,
and
was
then
published
,
so
the
NDVI
model
based
on
web services
can
be
accessed
through
an
internet
explorer
,
that
is, NDVI is efficiently
and
effectively
shared
based
on
this
method.
In
this
way
,
other
spatial
computing
models
can
also
be
encapsulated
with
web services. Users
who
want
to
use
some
spatial
computing
models
can
search
the
network
for a
proper
model
