Final Charter for Working Group
As more and more resources become available on the Internet, there are
immediate and pressing needs for some applications to acquire spatial
location information about certain resources or entities. These
applications include navigation, emergency services, management of
equipment in the field, and other location based applications.
The objective of the Spatial Location WG is to develop a payload format
to solve the following problem: How can an application represent the
spatial location of an identifiable entity, via or represented on the
Internet?
The payload shall define the spatial location in (at least) a
geo-centric three dimensional coordinate representation (with a
timestamp) of a uniquely identifiable entity.
The work items for the Spatial Location (SLO) Payload are:
-
Spatial Location Representations. For interoperability reasons, a
single absolute/default format shall be supported by all SLO-aware
entities. This format shall have (at least) Longitude, Latitude,
Altitude and a Timestamp when these values were last known. In
addition, a framework for adding any optional spatial location
representations shall be specified. Though, this group shall not
define any optional spatial location representation. Defining
optional representation(s) can be a future work effort. -
SLO Payload Coding Mechanism. There must be a coding mechanism
selected/designed for coding/decoding SLO Payload. The coding
mechanism must be supported by all SLO-aware entities. -
Investigating the requirements of SLO payload on application and
carrier protocols. The investigation by this group will focus
on:
-
Representation Negotiation Mechanism Requirements,
-
Requirements of Server Discovery,
-
Transport related Security, QoS and Policy Requirements, etc.
-
Requirements for Applications to utilize SLO Payload
What this group will not focus on during the initial chartering,
shall be the following:
- Descriptive Location
- Location Assisting
- Generic Measurements
- Non-earth based location systems (ex: heliocentric)
