Colleagues,
For info. I will respond to this after 21st April as I am travelling in India
till then.
Best wishes,

Regarding Dr. Anand’s concerns and the referenced letter below:
Esri has long understood the importance of interoperability between systems and
users of geographic information and services. Esri has participated in the
development of national, information community, OGC, and ISO TC 211 standards
from the development of the US Spatial Data Transfer Standard in the 1980s
through the development of OGC Geopackage today. As a sustaining member of
ASPRS and a Principle member of OGC, Esri would gladly participate in efforts
to further the development of open LIDAR and point cloud standards. Keep in
mind that ASPRS owns and maintains LAS, along with other spatial information
standards, and would have the lead in moving it into OGC or ISO TC211 for
further work if they so desired. Esri will continue to support and use the
ASPRS LAS standard; the Optimized LAS (see FAQ at
https://github.com/Esri/esri-zlas-io-library) is not intended to replace LAS
but to enhance access to remotely stored LIDAR information for our users.

Subject: [TC-Discuss] Open Letter for the need for Open Standards in LiDAR
To all colleagues in Academia, Government and Industry who have interest in
maintaining Open Standards:
On behalf of Geo for All community,
http://www.geoforall.orghttp://www.geoforall.org/, I would like to bring to
your kind attention a significant development that can lead to undermining our
principle for Open Geospatial Standards. I request you review the wikipage
http://wiki.osgeo.org/wiki/LIDAR_Format_Letter that is meant to represent our
concern and allow for ongoing input and expression by our geospatial community.
We specifically thank Martin Isenburg (author of LASzip and LAStools,
http://laszip.orghttp://laszip.org/ and
http://lastools.orghttp://lastools.org/) for bringing this matter to our
attention (email below) and an email thread of our initial discussion of this
subject that highlight the wider implication of this issue
http://lists.osgeo.org/pipermail/ica-osgeo-labs/2015-March/001225.html
We request all who wish to support this effort to protect Open Standards for
Geospatial data to kindly add your name , email, affiliation details to the
wikipage directly or email Patrick Hogan (Email -
patrick.ho...@nasa.govmailto:patrick.ho...@nasa.gov ) with the subject
heading Support for Open Geo Standards and the following fields (Name, Email,
Affiliation ) and we will gladly add this to the wiki.
There is current interest by the OGC in pursuing point cloud encoding
standards, including a member-initiated mechanism to extend LAS data with
OGC-standard XML content. The OGC invites interested members who wish to work
on this effort to please contact Scott Simmons (Executive Director, Standards
Program E-mail :
ssimm...@opengeospatial.orgmailto:ssimm...@opengeospatial.org ) to register
their interest and discuss details. OGC will also be holding an ad hoc session
at our next Technical Committee meeting in Boulder, CO, USA in June 1st (more
details will be send soon) to bring together all interested from all sectors
(government, industry, academia) for this and plan next steps. We welcome
feedback and input from Esri and invite them to join this effort to support
open LIDAR formats.
I thank you all again for your attention and support for this important matter.
Best wishes,
Suchith Anand

Hi all,
A number of us have been collaboratively developing an Open Letter asking key
stakeholders to avoid fragmentation in LiDAR standards.
It starts:
We, the undersigned, are concerned that the current interoperability between
LiDAR applications, through use of the open LAS format, is being threatened
by ESRI's introduction and promotion of an alternative Optimized LAS
proprietary format. This is of concern since the
