Remote Sensing and GIS

Working Group


To share information about, develop resources for, and support networked research related to remote sensing and GIS in the LTAR network.


  • To identify remote sensing and GIS technical expertise within the LTAR network, and to serve as a conduit for collaborative partnerships.
  • To assist research working groups with identification of available remote sensing and geospatial data products.
  • To identify a geospatial data sharing platform for networked research; establish spatial specifications (e.g. projection parameters and accuracy levels).
  • To work with other groups to develop best practices for working with and curating network-wide geospatial data, especially for new or emerging technologies (e.g. UAV data).


  • Hold regular meetings to share updates.
  • Update the survey on remote sensing and GIS expertise to make it relevant to the project plans resulting from the 2018 Annual Meeting.
  • Make expertise lists available to the wider LTAR community via the LTAR website.
  • Create a listing of recommended geospatial datasets including:
    • geospatial data collections available across the network and publicly, and
    • contact point information
    • access tools for remote sensing data (e.g. Github code, etc.)
  • Develop a geospatial data sharing platform strategy for LTAR geospatial data, including an image service.
  • Work with the IMTF to create a data management plan for UAV data.
  • Write a one-page fact sheet for the RS+GIS working group, following the ARS template.
  • Lead the development of a collection of 4-6 manuscripts on remote sensing frontiers in LTAR research, for submission to a journal such as Remote Sensing of the Environment.


  • Prioritization of LTAR research questions related to RS/GIS.
  • Identification of RS/GIS expertise currently present within the LTAR network, as well as sites lacking such expertise.

Datasets Produced

For the LTAR 2016 Annual Meeting in Archbold, we compiled a list of datasets recommended for inclusion in standard geospatial data holdings of LTAR. These datasets already exist from various public sources. However, they do not all exist in a centralized data archive for LTAR. Work is underway with the Information Management Task Force to specify and develop a centralized working geospatial web service for LTAR, including an image server. Once developed, we may decide to compile base layers for all sites and make them available through a LTAR-focused web service.
